• SATA Windows 7 Problems

  - by Isaacs

  Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit. Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives. Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..). Oddly enough if I boot to a ubuntu everything works fine. Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!

• How would I setup iMail to forward a user's mail to another service w/o leaving a copy locally?

  - by Scott Mayfield

  I have an iMail 2006 server installation in which I have a particular user that has several aliases that all point to a single user (me, for the record). I've been copying all of my mail to GMail and reading it there, but it annoys me that I have to go back weekly and log into my mail account on iMail and delete between 6 and 10 thousand copies of messages I've already received, in order to keep my mailbox from filling up (yes, I have it set with no quota, but I consider it bad form to just let the box grow indefinitely). I've got the copying setup via an inbound user rule, but I'm wondering how to accomplish a "copy and delete" rule. The manual isn't clear on what happens with multiple matching rules (will they be processed in order, or is it a first match situation?) and there isn't a means to combine multiple actions into a single rule. If I use the "forward" action, I THINK that it's going to screw up all the sender information once the mail reaches my GMail account and show it as coming from me instead of the original senders (can anyone confirm that this is accurate?) An easy answer would be to delete my user account entirely, replace it with an alias that maps to my GMail account, but then I would lose my ability to log into the system for admin duties. So that leads me to creating a second, lesser known account for admin use, but since it's a real account, sooner or later I'm going to get mail sent to it and I'll be back to the same situation of having a user account that doesn't get emptied periodically. I imagine I can set the quota to 0 MB to cause all incoming mail to my admin account to bounce, or setup an inbound rule to bounce everything, but this is starting to sound kludgy to me. Does anyone know of a more direct work around to copying a user's incoming mail to an outside server and then deleting the local copy w/o removing their account entirely? Or is this just wishful thinking? Thanks in advance. Scott

• How does Linux determine the SCSI address of a disk?

  - by Chris Sears

  Greetings, I'm working with RHEL 5.5 guest VMs under VMware ESX 4. When I configure the virtual disks in the VM hardware settings, each disk has a SCSI address in the format "N:M". For example, "1:3" would mean SCSI host number 1 and SCSI target ID 3. When I look at the disk info from the VM's BIOS or a Windows OS, the detected SCSI address info matches up with the virtual hardware settings. But under Linux, the SCSI address components don't match up, at least not completely or consistently. I've tried the three supported virtual SCSI and SAS drivers and they all seem to be "broken", but in different ways. Here's a list of the virtual hardware addresses vs what was detected under Linux with each of the drivers: Driver vHW Addr Linux Addr -------- -------- ---------- LSI SAS 0:0 0:0 LSI SAS 0:3 0:1 LSI SAS 0:6 0:2 LSI SCSI 1:1 2:1 LSI SCSI 1:4 2:4 LSI SCSI 1:7 2:7 pvSCSI 2:2 1:2 pvSCSI 2:5 1:5 pvSCSI 2:8 1:8 My main question is why does this happen under Linux? The next question is: how do I get it fixed or fix it myself? If I was going to guess, I'd say it's an issue with how the kernel is handing out the SCSI host number and how the Linux SCSI driver (included with VMware tools) is detecting the SCSI target number. Perhaps the order the drivers are loaded also has something to do with the issue. I'm guessing this would not involve udev, but I could be wrong. Any thoughts would be appreciated. Thanks! PS. My environment is VMware, but I don't need an answer for these drivers specifically. I imagine this might be a problem with any SCSI driver under Linux.

• Eee PC Seashell series netbook screen is cut off at bottom no matter the resolution

  - by Yzmir Ramirez

  I have an Eee PC 1015PE Seashell netbook running Windows 7 Home Premium with an Intel Graphics Media Accelerator 3150 (8.14.10.2230) with a "Generic Non-PnP Monitor" detected. I tried: Changing the resolution (Control Panel = Appearance and Personalization = Display = Screen Resolution) to 1024x768 Updating the video driver (to 8.14.10.2230) Uninstalling the driver and rebooting Pressing the Windows Key + "-" (magnifier) Pressing Ctrl + Mouse Scroll only resizes the desktop items Pressing Fn + F4 shows 1024x600 (which I think is what I should be using, but nothing happens) EDIT: Changed from Landscape to Portrait and it works Attached an External Monitor and when I extend or set as desktop it works only on the External Monitor (shows up as "Generic PnP Monitor in Device Manager) Basically the bottom inch of my desktop is off-screen hiding my start bar, but my wigets are in their proper position (the start bar is not hidden). Pressing Ctrl + Esc shows the start menu but its cut-off. I'm pretty sure I should be using 1024x600 resolution, any advice? What's odd is that this only started happening recently. EDIT2: Here are some screenshots showing the problem: Resized Window to fit: Opened Start Menu - notice it cut off: Maximized window and then scrolled down - notice no Start Menu: I downgraded my graphic driver I downloaded from the Intel Download Center for the Graphic Media Accelerator 3150 (now: 8.14.10.1972) and now my "Generic non-PnP Montior" detects as "Digital Flat Panel (1024x768 60Hz)".

• How does the "Steam" platform work? Is it DRM? Can I trust "Steam"-powered games?

  - by Chris W. Rea

  So – I just bought the new game Supreme Commander 2. This question is not about the game, but about the online software installation platform that it seems to require. I haven't bought a game in a long time, and I'm puzzled: Apparently, SC2 is a "Steam"-powered game. When I went to install the game, it asked me to either create a new Steam account, or log in with an existing account. I clicked "Cancel" because I don't plan to play online and I don't want anything unnecessary installed on my computer, since I only plan to play single player! However, after clicking "Cancel", the installer asked for my confirmation that I indeed wanted to cancel installation of the game! I thought I was just canceling the "online" portions! So I really want to know: How do "Steam" powered games work? Is this essentially a form of DRM (Digital Rights Management)? Can I trust this software platform? Has anybody done any independent verification on how this platform works? (I'm very leery of any DRM after the Sony BMG CD copy protection scandal. Thank goodness for Mark Russinovich.) Does the "Steam" platform install anything particularly nasty or unwanted on my computer?

• No sound through headset - only mic is working

  - by Kristis

  I noticed that no sound is being played to my headphones. The laptop has a conexant sound card together with the sounds apps provided. But the thing is that I also noticed that now instead of one playback device - 2 are presented: speakers and headphones. And while speakers do play sound nicely - even test sound are not played through headphone output. Also, headphone output does not have a jack assigned to it, while speakers have L R Rear panel Analog Jack(my laptop does not have a jack on the back - only on the right). Also - my headphones have a mic as well - and when I plug it in - the mic is working(using top panel digital jack),but the headphones themselves are not. And laptop is recognizing when audio device is plugged in. And I checked the headset on other devices - the headphones are working. I have tried updating drivers, rolling back drivers and completely uninstalling drivers and then restarting - nothing helped. I imagine that I somehow need to reconfigure the jack configuration just have no idea how and where. Any suggestions? Thanks

• External USB HD with -optional- mains?

  - by Stephen

  Hi, I'm Christmas-present-buying, and I'd appreciate recommendations for a USB HD with an optional mains power input. I've hunted, but can't find all the information I want (partially due to sketchy product specifications). Background: This is for a digital TV which I do not own, and so I'd like to get it correct first time. The TV has a USB port to allow recording straight to disk, but the manuals don't say how much power can be drawn through the USB port. The manual's instructions state, possibly generically, to plug the drive in before connecting to the TV. Ideally I'd like a small (2.5"?) drive which can draw power over USB, with an mains power input if it turns out the USB port on the TV doesn't offer enough juice. The ideal is to use one cable, two max. A powered USB hub would introduce too much clutter. I've spotted that the LaCie Petit drives have what appears to be an additional power input, but I'm not even sure from the specs what that is. And the device doesn't ship with a mains adapter. Suggestions?

• X.org - mouse gets stuck on press

  - by grawity

  I'm using Arch Linux. Very often, when I click on something, the OS thing sees the mouse press but not the release. If it was a link or file I clicked, moving the cursor would drag it too. Hammering the same mouse button again gives no effect. Usually, if I tap the touchpad (ALPS), the system finally sees both press and release of that, and I can continue working. (This might be because it uses a different driver - synaptics instead of evdev.) As you can imagine, this is quite annoying even for someone who spends 70% of his life in front of a terminal app. This is not a mouse issue - I'm on a laptop, and this affects both the Trackpoint thing and an external USB mouse. This is not a DE or window manager issue - I have used GNOME (with Metacity, Compiz and Xfwm4), Xfce (with Metacity and Xfwm4), mwm, twm, awesome, and wmii. Doesn't seem to be a hardware thing - after rebooting into Windows XP, everything works fine. hal is used for the auto-configuration of devices (as I have to disconnect the USB mouse often), so Xorg.conf really has nothing of relevance. Xorg -version shows: X.Org X Server 1.6.3.901 (1.6.4 RC 1) Release Date: 2009-8-25 X Protocol Version 11, Revision 0 If it changes anything, the laptop is stone-age Dell Latitude C840. I kinda suspect either hal or the evdev thing to cause it, but I really have no ideas on what to check further. In other words, HALP!#$ This thing is driving me nuts.

• Scheduling Automatic Backups for Virtual Private Web Server running CENTOS 6.3 and WHM

  - by Oliver Farrell

  I'm pretty new to administering my own VPS - but thus far am finding it quite a compelling experience. There's something quite refreshing about having complete control over everything it does. One thing that I would like to look at is a suitable backup solution (a few times a day). My current setup is as follows: I'm running a CENTOS 6.3 VPS with a single 25GB hard drive solely for the purpose of hosting websites. I'm using WHM & cPanel for administering them. I now plan on adding an additional hard disk and hooking it up to my VPS. What I'm not sure about is how I get the two disks talking and get the backup process going. I'm not a seasons SSH-er so don't really know where to start. I'm hosting with Serverlove (one of the best hosting providers I've used) and am provided with a number of unique identifiers for each hard disk so I imagine these may play a part in linking them together. I appreciate that this is a little vague (I'm clutching at straws) but any assistance is very much appreciated.

• Does btrfs balance also defragment files?

  - by pauldoo

  When I run btrfs filesystem balance, does this implicitly defragment files? I could imagine that balance simply reallocates each file extent separately, preserving the existing fragmentation. There is an FAQ entry, 'What does "balance" do?', which is unclear on this point: btrfs filesystem balance is an operation which simply takes all of the data and metadata on the filesystem, and re-writes it in a different place on the disks, passing it through the allocator algorithm on the way. It was originally designed for multi-device filesystems, to spread data more evenly across the devices (i.e. to "balance" their usage). This is particularly useful when adding new devices to a nearly-full filesystem. Due to the way that balance works, it also has some useful side-effects: If there is a lot of allocated but unused data or metadata chunks, a balance may reclaim some of that allocated space. This is the main reason for running a balance on a single-device filesystem. On a filesystem with damaged replication (e.g. a RAID-1 FS with a dead and removed disk), it will force the FS to rebuild the missing copy of the data on one of the currently active devices, restoring the RAID-1 capability of the filesystem.

• Corliss Expert Group Home Security: How to Secure Your Home without Spending Too Much?

  - by Mika Esmond

  HOME SECURITY: HOW TO SECURE YOUR HOME WITHOUT SPENDING TOO MUCH Imagine if there were no burglar or criminals who threaten the safety of our homes; we will be surprised how much savings we would have on several things we do to secure ourselves and our loved ones. We would not need fences, gates with locks, doors locks, window grills, CCTV cams, perimeter lighting, shotguns and baseball bats. The cost of maintaining these things can run up to the entire cost of building another room or, in some cases, a whole new house. The rationale for home security is the same for national security. A nation maintains an army whether it has enemies or not; so, whether burglars will come or not, we have to prepare for the eventuality. Hence, we end up spending for something we might never put into the actual use it was intended for. You buy a pistol and when a burglar breaks in you fire the gun either to scare or disable the intruder. We hope we will never have to use these things; but we still buy them for the peace of mind that comes from knowing we can secure or protect our family and home.

• ubuntu 9.10 installer doesn't recognize the hard drive

  - by dan

  I downloaded Ubuntu 9.10 x86_64 and am trying to install it on a fairly modern system with a Gigabyte GA-MA770-UD3 motherboard. Ubuntu 9.04 installed fine and still will when I stick that disc in, but 9.10 doesn't see my hard drive (western digital 250GB). If I boot from the disc, I can install gparted and it does recognize the drive, but when I try to start the install process from the live disc, Ubuntu again doesn't recognize the hard drive. I checked /var/log/messages and see this: Nov 12 17:28:08 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'. Nov 12 17:28:08 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.

I checked my BIOS, SATA is enabled and is set to IDE mode, so there shouldn't be software RAID, but nonetheless, I added nodmraid to the boot line and tried again. It still doesn't recognize the drive. I checked /var/log/messages again and now see this: Nov 12 17:49:38 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was boad, boot with 'nodmraid'.

I've tried all of the various BIOS settings for SATA. IDE,RAID, etc. Nothing seems to work.

• Can I use multiple URLs in the URL field of KeePass?

  - by Sammy

  I am using KeePass version 2.19. What I would like to do is have more than just one URL address associated with a given user name and password. The entry for a given website might look something like this... Title google User Name email Password pass URL https://accounts.google.com/ServiceLogin?hl=en&continue=https://www.google.com/ https://accounts.google.com/ServiceLogin?hl=sv&continue=https://www.google.com/ https://accounts.google.com/ServiceLogin?hl=de&continue=https://www.google.com/ As you can see the ?hl=en changes into ?hl=sv and then to ?hl=de for the three different languages in which I wish to view the Google log-in page. But this of course could be something completely different, like different web services from the same provider like YouTube and Gmail by Google. Very much like SE where you have several websites but only use one user name and password. I imagine something along the lines of having multiple entries for one and the same website, where KeePass would actually prompt you to choose which one you want to use. So you have several user names and passwords that use the same URL. But is it possible to have several URLs using the same user name and password, so that KeePass asks me "to which of the following three URLs do you want to auto-log into with this password"?

• How to Eliminate Black Bars from Powerpoint videos ?

  - by appu

  Hi, I am running a digital signage system for my client. The basic installation is a vertically oriented 42" LCD TV with a 1920x1080 screen resolution (reverse of 1920x1080 when setup normally, i.e. landscaped). Please check out the following link for a basic screen divisions layout I want to setup. http://flickr.com/photos/55097319@N03/5410208856 In the division labeled "ppt" I plan to run a powerpoint presentation. The screen division is 360x1476 resolution. As there isn't an option in powerpoint to specify slide size in terms of resolution so according to this article on indezine http://indezine.com/products/powerpoint/books/perfectmedicalpres02.html to get a screen resolution of my preference I divided 360 and 1476 each by 72 which gives me 5"x 20.5" as the slide size for my ppt. After setting up slide size as per above dimensions, I used sizer (http://brianapps.net) to resize my ppt window to 360x1476 so that when I record I do not get any black bars. But after launching recording there are side black bars visible which camtasia records and brings-inside cam studio with black bars. http://www.flickr.com/photos/55097319@N03/5409597049 My question is that after doing the above and as explained in the following video link why do I still get black bars. http://feedback.techsmith.com/techsmith/topics/eliminate_black_bars_in_your_powerpoint_recordings Is there an option in camtasia to stretch the recording to cover up black bars or any other alternative way I can get rid of those black bars while I get a ppt recorded as per my preferred dimensions. Notes: In the techsmith video above it asks to adjust my desktop screen resolution which my display chipset does not allow me to set. I set up show in powerpoint to be "browsed by an individual(window)". Also signage software only supports swf's and video file formats natively and not ppt, pptx etc. Thanks bhavani.

• Network latency and speed of light

  - by James

  This was kinda of covered by the following Is minimum latency fixed by the speed of light? , but i would like to add the follow up a bit. The scenario is as follows; we have two opposing sites one on the West Coast of the US and one in Ireland. The customer is in central Europe, and has requested a latency test. Ireland gives responses of ~65-70ms. However the West Coast guys claim to be faster with a response of 60ms. Now a quick check says that light in fiber would take about 42ms to make the trip to the States and 8.5ms to Ireland. So obviously this is a single hop and does not include routers, switches, firewalls, protocol overhead etc. Would I be right to call BS on their figures? As a final note I tested a ping to Google IP address that was allegedly on the west coast from a site that covered a similar distance and was amazed to get a response time of 20ms. Suggesting ICMP packets that travel twice the speed of light. So A) what am I missing B) Am I right to suspect shenanigans? UPDATE: Guys thanks so far for your help and I have been reading various previous questions on this. About 5 years I had an issue where the hop from the UK to Ireland added 10ms of latency no matter what we did. In the end I moved the servers; So imagine my surprise when I have guys that claim they are 5ms faster with a transatlantic trip. So again should I call BS? Oh and assume both sites are normal mortals that don't have access to Google magical routing, warp dives or flux capacitors. :)

• Loss of network connectivity when playing video on Optoma HD180 projector

  - by Jeff Fohl

  Hi Folks - New to Super User, so I hope this question fits in with the guidelines. Very strange problem I am having, and I am at a loss as to how to continue troubleshooting this one. The basic problem is that when I attempt to watch streamed video on a particular display device (an Optoma HD180 projector), my network connectivity drops like a stone to barely measurable levels. This is my setup: I have a Dell H2C 730x running Windows 7 64bit. This particular computer has two ATI Radeon HD 4800 video cards. I have two Samsung 22" monitors connected to one card, and an Optoma HD180 digital projector connected to the other card via an HDMI cable. My internet connection is normally a reliable 6Mbps. The problem I am having occurs when I stream video (or even just browse the web) on the Optoma Projector. When I do this, my internet connection drops to practically zero (just a few kilobits per second). When I move the browser away from the projector, and over to one of my Samsung monitors, the internet connection comes right back. Note that the Optoma projector is on and enabled as a third monitor all this time. I can move the mouse around on the projector without triggering the problem. I tried pinging my router when I was playing a movie on one of the monitors, and I get a 1 millisecond response. However, when I have the movie playing on the Optoma projecter, pinging the router gives me response times in the hundreds of milliseconds, or times out completely. So, it clearly is something local to my machine - and not some sort of throttling occurring down the line. I would think that it is possibly something to do with the HDMI driver conflicting somehow with my network driver (which is a USB-based wireless connection). This one has me really stumped. Anyone have any ideas?

• Can't upgrade NVIDIA GeForce 310M display driver on Acer Aspire 5745PG

  - by Emerson

  I've been for days already trying to update my video driver. I have an Acer Aspire 5745PG with a "NVIDIA GeForce 310M" board, and I was trying to run Sony Vegas video editor with Boris Continunn plugins. It happened that some of the plugins, like BCC Text Extrude wouldn't work, showing the message "Insufficient depth resolution to run Blue". I then read somewhere that updating the display driver would do the trick. That was when my nightmares started, I lost already good 3 nights trying to sort this out, without success :( The display driver that was before (and that I current have after restoring) was the version 8.16.11.8997. First thing I tried was downloading the 8.17.12.6619 driver directly from Acer, which was shown as the latest version from Acer website: http://support.acer.com/product/default.aspx?modelId=2466 Running it would say "Diver Package Failure - Setup failed to read the required Display Driver to be used with this package" I then tried directly the NVIDIA own driver, which the latest was version 296.10: http://us.download.nvidia.com/Windows/296.10/296.10-notebook-win7-winvista-64bit-international-whql.exe That gave me similar error message :/ So after some researching I found out that some people had the same issue and they had to change the configuration file to allow the installer to recognize this NVIDIA board: http://forums.nvidia.com/index.php?showtopic=222904 That topic said to look for the "Device Instance Id" property of the "NVIDIA GeForce 310M" display , which I couldn't find, instead I found the "Hardware Id", which seemed to be the right one. I followed the instructions and changed the inf file first for the Acer installation, and after for the NVIDIA own driver. It actually managed to go ahead with the installation in both instances, but the only thing I got was a black screen, while the computer still apeared to be running fine. I had to hard reset, and then it would come back with generic vga driver. I could only get my display back using the recovery function. I imagine thousands of this notebook was sold, and it can't have its driver updated?? Could someone help me with this?? Thanks Echo

• NGINX Configuration Error using Codex Example: Is This a Typo in Codex?

  - by jw60660

  I installed NGINX using this tutorial: C3M Digital NGINX Tuturial but after reading this article on security issues with "cut and paste" configuration tutorials: Neal Poole's article regarding security and NGINX configuration I decided to follow Poole's suggestion to use the configuration suggested in the WordPress codex: Codex on NGINX Configuration I used the Codex configuration for a multisite installation using W3 Total Cache. When attempting to start NGINX I get an error saying that the /etc/nginx/nginx.conf test failed. The error message was: "Restarting nginx: nginx: [emerg] unknown directive "//" in /etc/nginx/sites-enabled/teambrazil.com:18" When I looked at my site specific configuration at that path I noticed the rewrite rule in the server block was: rewrite ^ $scheme://teambrazil.conf$request_uri redirect; That line in the Codex example was: rewrite ^ $scheme://mysite.conf$request_uri redirect; That looked like a mistake to me, and I changed my line to: rewrite ^ $scheme://teambrazil.com$request_uri redirect; I then attempted to restart NGINX but got the same error message. My question is: is that a mistake, and is there anything more I have to do aside from restarting NGINX after making this change. As suggested by both tutorials I set up the directories: /etc/nginx/sites-enabled and /etc/nginx/sites-available and created the appropriate symbolic links using: touch /etc/nginx/sites-available/teambrazil.com ln -s /etc/nginx/sites-available/teambrazil.com /etc/nginx/sites-enabled/teambrazil.com Is there something else I need to consider after making this correction? Or was it not an error in the first place? I'm pretty stuck here. BTW, I am using Debian squeeze as an OS on Amerinoc's VPS. I'm just getting familiar with VPS administration and am pretty much a noob. Thanks very much, would appreciate any input.

• Turn Excel spreadsheet into a formula

  - by ?????? ??????????

  I have an Excel spreadsheet that has a complex computation that is not trivial to turn into a macro or a single-cell formula. The spreadsheet has a about 10 different inputs (values a human enters in different cells of the spreadsheet) and then it outputs 5 independent calculations (in different 5 cells) based on that input. There calculation is using some pre-entered data in the spreadsheet (about 100 different constants) and doing some look-ups on them. Now I would like to use this whole spreadsheet as a formula on a different spreadsheet to calculate a set of input values and produce the corresponding set of output values. Imagine this as creating different table with 10 columns for the input variables and 5 columns for the outputs, then copying each input into the other spreadsheet and copying back the output in the results table. For instance: - A1, A2, A3,... A10 are cells where someone enters values - through a series of calculations B1, B2, B3, B4 and B5 are updated with some formulas Can I use the whole series of calculations from A1..A10 into B1..B5 without creating one massive huge formula or a VBA macro? I want to have a set of input values in 100 rows from A100, B100, C100,... J100 onward. Then do some Excel magic that will: 1. copy the values from A100...J100 into A1 to A10 2. wait for the result to appear in B1 to B5 3. copy the values from B1 to B5 into K100 to O100 4. repeat steps 1 to 3 for all rows from 100 to 150

• Win7 System folder contains infinitely looping SYSTEM(!) directory

  - by Matt

  My Windows 7 Enterprise computer has been crashing fairly frequently recently, so I decided to boot up in safe mode and run the TrendMicro client I have installed. It froze about 10 minutes into the full system scan, so in the spirit of http://whathaveyoutried.com, I started scanning each folder individually. When I got to ProgramData, the AV failed with an uncaught exception. I then went down a level and tried scanning Application Data, which failed as well. Imagine my surprise when I open the folder just to see the same folder again! As far as I can tell, this folder loop continues indefinitely. (If you are trying to recreate this, keep in mind that ProgramData is a hidden folder.) I'm actually a bit concerned that these are system folders, as this is a brand-new computer with a clean installation. I guess I have three questions: Has anyone else seen/experienced this before? I'm running Win7 SP1. How do I fix this? I've run CHKDSK \F with no success (although it was incredibly slow). What are the ramifications of an infinitely recursive directory? Theoretically speaking, each link takes up memory, so shouldn't I have no space available on my hard drive? (I've got about 180GB left.) I noticed that the tree view on the left only shows the "linked folder" icon on the deeper folders--does this mean anything special? (I've circled the icons or lack thereof in red.) How can the OS even resolve this aberration? And above all, what would happen if I were to select "Expand all folders"??? :P Matt

• Send keystrokes simultaneously to both host and slave over internet?

  - by donodarazao

  I would like to watch movies with a friend who lives far away from me. For this, the playback should be synchronized on both our pc. However, we have some constraints: Due to our low bandwidth internet, any form of streaming solution wouldn't work. We do however both have the same copy of the movie on our harddisks. We use movies to learn languages and because of this, we very frequently pause and rewind. The typical "3...2...1...go!" solution over skype wouldn't work because it would soon get out of sync. I imagine an approach that sends keystrokes simultaneously to both our pc would work (for example, if I press space to pause the movie at my pc, space should also be send to his pc). Any ideas how this could be realized? I looked into Synergy and InputDirector, but both neither seem to be an option, because I don't want to see the desktop of my friend, I want to see my desktop Keystrokes should be sent simultaneously to both pc, not just to one pc We have both Windows 7x64, and we might use any media player (VLC, XBMC,...).

• Folder redirection GPO doesn't seem to be working

  - by homli322

  I've been trying to set up roaming profiles and folder redirection, but have hit a bit of a snag with the latter. This is exactly what I've done so far: (I have OU permissions and GPO permissions over my division's OU.) Created a group called Roaming-Users in the OU 'Groups' Added a single user (testuser) to the group Using the Group Policy Management tool (via RSAT on Windows 7) I right-clicked on the Groups OU and selected 'Create a GPO in this domain, and Link it here' Added my 'Roaming-Users' group to the Security Filtering section of the policy. Added the Folder Redirection option, specifically for Documents. It is set to redirect to: \myserver\Homes$\%USERNAME%\Documents (Homes$ exists and is sharing-enabled). Right-clicked on the policy under the Groups OU and checked Enforced. Logged into a machine as testuser successfully. Created a simple text file, saved some gibberish, logged off. Remoted into the server with Homes$ on it, noticed that the directory Homes$\testuser was created, but was empty. No text file to be found. From what I've read, I did everything I aught to...but I can't quite figure out the issue. I had no errors when I logged off about syncing issues (offline files is enabled) or anything, so I can only imagine my file should have ended up up on the share. Any ideas? EDIT: Using gpresult /R, I confirmed the user is in fact part of the Roaming-Users group, but does not have the policy applied, if that helps. EDIT 2: Apparently you can't apply GPOs to groups...so I applied to users and used the same security filter to limit it to my test user. Nothing happens as far as redirection goes, but I now have the following error in the event log: Folder redirection policy application has been delayed until the next logon because the group policy logon optimization is in effect

• How does USB device recognition work?

  - by GorillaSandwich

  I'm curious how USB device recognition works in Windows. I imagine it's something like this: When you plug in a device, it tells Windows "here's my device ID to tell you what I am" Windows looks to see if any drivers have been installed that match that device ID. The driver probably tells Windows what the device should be called - like "BlackBerry Curve" or "Canon Printer" If so, it somehow associates that device with that driver Otherwise, it looks for a matching driver online (if you let it) Am I right? If so, that still leaves some questions. When you install drivers, where do they go? Are they files in a folder, or do they get added to the registry? What is Windows doing when it first recognizes the device, thinks, and finally says "your new device is installed and ready to use?" Where does Windows look for missing drivers? Is it in their own database? Do device manufacturers submit drivers to Microsoft for inclusion there? Can anybody explain how this process really works? Also, do other OSes do this differently?
