• Finding the file that is on a bad block on a HFS+ volume (debugfs for HFS+)

  - by Blair Zajac

  I have a drive in our iMac that has bad blocks, as booting from an Ubuntu 11.10 live CD and using ddrescue -f /dev/sda /dev/null finds them. I'd like to get the drive to remap them by writing to the blocks, say using hdparm --write-sector, but I don't want to do this without knowing what's in those blocks and finding the file that owns them, so I can restore the file from another source. I found fileXray but don't feel like spending $79 to map a block to a file and hfsdebug has been taken offline. Are there suggestions on a tool or technique to use? I looked at all the Ubuntu HFS+ packages to see if they could provide this info but nothing jumped out at me. BTW, I used Disk Utility to erase the empty space, but it didn't get any of the bad blocks to be remapped, according to smartctl -A.

• Western Digital Mybook is creating folders I didn't create

  - by Rogue

  I have a WD MyBook which has been creating empty folders with a long string of numbers and alphabets and some shorter ones with just some numbers with a 0kb file in it Some of these can be deleted but some just stay put. It's irritating to find new ones everyday and now i have a collection of them which don't delete is there any way to delete these ? Edit: I have scanned the drive using Antivirus and AntiMalware Software so i don't think it would have a virus One solution is copying all the matter elsewhere and formatting the hard disk but there is not guarantee that these folders wont reappear.

• Robocopy hiding folders on backup drives

  - by Neil Barnwell

  I have a backup batch file that uses Robocopy to backup my files: robocopy "C:\" "G:\Default\RoboCopyBackup\C" /XF Pagefile.sys /XD "System Volume Information" "Recycler" "Temporary Internet Files" "Installer Cache" "Temp" /E /R:1 /W:0 /TEE /XJ This should create a folder structure on the external backup drive like so: G:\Default\RoboCopyBackup\C\... However, G: appears totally empty. What is weird, is that the folders and files are there! If I type the above path into the address bar, I see all the files and folders! Can anyone help me work out why? I think it might be some NTFS-based ownership/permissions thing but I'm not sure.

• Using MRTG's threshold feature to execute a php script

  - by Dan Fried

  I've set up mrtg using the online manual and the only online tutorial I found on the subject of thresholds, and the threshold just isn't firing. In my mrtg.cfg file, the relevant lines are ThreshDir: /path/to/mrtg/thresh ThreshMaxI[performance]: 1 ThreshMaxO[performance]: 1 ThreshProgI[performance]: /path/to/mrtg/scripts/alert.php ThreshProgO[performance]: /path/to/mrtg/scripts/alert.php The paths are right, because if I enter the paths wrong I get an error on executing mrtg. websitePerformance checks how long it takes to download the homepage, in milliseconds, so it should be exceeding the max every time. Alert.php is working fine when invoked directly from the shell, and when I point to a nonexistent script it tells me the script is not executable. No error messages are being generated, that I can find. The thresh directory is always empty. Why isn't the threshold being triggered by results that are greater than 1? Anyone have any suggestions?

• MacBook says to replace battery. Should I?

  - by Palantir

  Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P

• Customize side panel in Internet Explorer 9/Windows 7

  - by Kari

  I use Internet Explorer 9 with all the horizontal toolbars except the tab bar invisible to maximize vertical space. I have plenty of room at the side so I have the Favorites/Feeds/History panel open, usually on Favorites to replace the Favorites bar. I'd like to customize the shortcuts in this panel to display as large icons, similar to when you set the display in Windows Explorer to Large Icons and, long shot... change the backround color. The side panel does appear to be just a Windows Explorer window but it seems immune to any kind of tampering or customization, mainly because right clicking is disabled on the empty space. Changing browsers is not going to happen but can someone help out here?

• How to avoid printing nearly blank pages?

  - by joelarson

  How many times have you printed an email just to have the last page be 2 or 3 lines of a person's signature (or worse, the "This is confidential" copy inserted by corporate mailservers)? How many times has the last page contained just the footer of the website? Does anyone know of a utility or print driver that can help avoid printing blank or nearly-blank pages? I am not looking for techniques for avoiding this in specific programs -- if I take the effort of doing print preview and then adjusting the pages to be printed, then of course I can avoid it. What I want something I can install that, whenever I push "Print" to any of the various printers I print to with my laptop, it automatically says "hmmm... I bet he doesn't really want that page which is 95% empty" and possibly prompts me to say "do you really want to waste paper on this?"

• Print Preview Blank IE8

  - by Ben

  On a Windows XP, in IE8 print preview always appears completely blank except for header information. I can open the generated temp file in firefox and print it from there. I have tried browsing without addons to no success. I have tried re-creating the "%TEMP%\low" folder as described on the web, e.g. here: http://answers.microsoft.com/en-us/ie/forum/ie8-windows_xp/ie8-printing-does-not-work-preview-empty/920588e5-ccc4-4e24-83d6-606d5e3b1c70 ... all with no success.

• cannot run CMD script from Vista windows explorer

  - by jamesvista

  I am running Vista Home Premium. I tried to write a script to do some simple automation.... it does not work! even the most simple script like: @echo ON dir . does not get executed and only an empty CMD shell pops open when started from explorer. From the cmd windows there is no problem. This is really weird and I have never seen this before (but wrote many CMD scripts before) ftype cmdfile and batfile are unchanged from "%1" %* virusscan done - no problems Is there a policy setting that might have changed? Any ideas?

• Which home automation technology to choose? x10 zwave e.t.c. in UK [closed]

  - by Stewart Robinson

  I work away most of the week and have to leave my house empty. I would like to have home automation monitor and control my house. Naturally I want to be a bit of a geek and do some of it myself so I've researched stuff like x10, zwave, cbus e.t.c. but I want opinions on which I should use in my house. I have a Linux box that could be used to actually do controlling if needed. So which technology and why?

• ESXi 4.0u1 - backup/copy options

  - by Hanadarko

  I have a machine built using ESXi 4.0u1 and it has 3 hard drives. I have my hosts built on different hard drives but wondering about backup options. I do not have RAID but I have 3 drives and 1 is totally empty. I had been using it to store ISOs for loading. So what options do I have to either create a 1 time copy onto the spare drive or some sort of snapshot to the spare drive? - There must be some way to do this either via the vsphere client or ssh into the ESXi box and go from there. Thoughts? -JD

• How to get iTunes to recognize that certain ID3 tags have been removed from files?

  - by Nick Meyer

  I use MusicBrainz Picard to manage the ID3 tags on my MP3 collection and iTunes for playing them and managing my iPod. I have Picard set to remove the Composer tag from any files that don't also contain the word "Classical" in the Genre tag. I've run Picard and it has removed the Composer tag from many of my files. However, iTunes keeps displaying the old value of the Composer field. I have tried right-clicking on the file to update, choosing "Get Info" and clicking OK. This has no effect on the Composer field when it has been removed entirely; it only refreshes the displayed value when it has been changed from one non-empty value to another. How can I get iTunes to stop showing the old values for tags that have been removed? Please note I don't want to lose other iTunes metadata such as ratings and play counts, so removing the files from the iTunes library and re-adding them is not an option.

Event Viewer is full of 2019 errors: The server was unable to allocate from the system nonpaged pool because the pool was empty Does anyone have experience with this specific issue? I have found some info with Google, but would like to hear what the pros at SF have top say. This is a Windows 2000 server.

• Installing a 3.5" hard drive in a 2.5" bay?

  - by Javawag

  I know this question seems ridiculous, but my server (actually a Mini-ITX computer) has a 2.5" hard drive bay and an empty CD-ROM bay underneath it. If I removed the hard drive bay, I could probably mount a 3.5" hard drive in the CD-ROM bay which is unused... I know it's a big of a kludgy way to do things but it does mean upgrading the hard drive to 2TB is much cheaper. My question is: are the power requirements of a 3.5" disk the same as 2.5" one? I know the connectors physically will still fit, but I don't want to destroy my server!

• Citrix XenApp application does not have keyboard focus when launched

  - by Jason Pearce

  On new or existing Citrix XenApp 4.5 servers, I am having problems streaming the Allscripts Pro EHR application via the XenApp web interface. When users launch the application via the Citrix XenApp web interface, the application does not have focus, preventing users from typing in their username and password. If they use their mouse to select either the username or password fields, they still cannot enter any text. However, if they do any of the following actions, they can then enter in their username and password and the application runs without problems: Click on the Login button with empty fields. Logon fails but they can then enter their credentials. Minimize the login window and then maximize it. They can then gain keyboard focus to enter their credentials. What might be preventing this particular application from having focus when it launches?

• Changing bounds of excel file embedded in powerpoint

  - by Brett

  When I embed an excel files into powerpoint, I'm having two issues. On some of the spreadsheets, empty columns are displayed on the right hand side of the powerpoint slide On other spreadsheets that are too large to fit, I can't adjust the bounds of what I'd like to be displayed on the slide. So, I couldn't choose a larger area to display of the excel spreadsheet and just size it down. It arbitrarily chooses where to cut off the excel spreadsheet on the slide. Is there any way to adjust which part of the excel file is embedded?

• Reliable procedure/tool for removing print drivers in Windows 7 (domain environment)

  - by ultrasawblade

  One of the troubleshooting steps in resolving printer-related issues with any version of Windows is to remove installed print drivers and then reinstall the drivers. This is a domain environment and drivers are pulled from a print server. I've had occasion to need to do this on a user's system running Windows 7 Enterprise 64-bit. These procedures don't work: Removing the printer from Devices and Printers (doesn't remove driver obviously) Doing the above, going into Server Properties, and attempting to remove the driver (fails with a "driver in use" error) Opening an empty mmc, adding the Print Management snap-in, and attempting to do the above. Doing sc stop spooler and sc start spooler before doing both of the above Now I know it's possible to remove drivers with the spooler service stopped and then going into the spool directory, as well as deleting registry entries. I'm asking if a tool exists to do this where I can just select the driver in question and it be removed.

• How to use public-key ssh authentication

  - by Poma

  I have 2 ubuntu 12.04 (beta) servers (node1 and node2) and want to establish passwordless root access between them. Other users should not have access to other boxes. Also note that ssh default port is changed to 220. Here's what I did: sudo -i cd /root/.ssh ssh-keygen -t rsa # with default name and empty password cat id_rsa.pub > authorized_keys then copied id_rsa & id_rsa.pub to node2 and added id_rsa.pub to authorized_keys. Both hosts have the same /root/.ssh/config file: Host node1 Hostname 1.2.3.4 Port 220 IdentityFile /root/.ssh/id_rsa Host node2 Hostname 5.6.7.8 Port 220 IdentityFile /root/.ssh/id_rsa Now the problem is that when I type ssh node2 it asks me for password. What may be the problem?

• NGINX 301 and 302 serving small nginx document body. Any way to remove this behaviour?

  - by anonymous-one

  We have noticed that when using nginx internal 301 and 302 handling, nginx will serve a small document body with the appropriate Location: ... header. Something along the lines of (in html): 301 redirect - nginx. As appropriate in the above behaviour, a content-type text/html and content-length header is also sent. We do a lot of 302 and some 301 redirects, the above behaviour is wasted bandwidth in our opinion. Any way to disable this behaviour? One idea that crossed our mind was to set error_page 301 302 to an empty text file. We have not tested this yet, but I am assuming even with the above, the content-type and content-length (0) headers will be sent. So, is there a clean way to send a "body-less" 301/302 redirect with nginx?

• Macbook Pro 15-inch replacement battery.

  - by ricbax

  So I've finally got to the 300+ cycles with my MBP 2008's original battery. Apple is pretty much "on the money" too! I am at 79% Health and getting the Condition: Replace Soon warning. So I went out to the closest Apple Store and bought a replacement. I would like to get the same lifespan out of my replacement if possible. My question is: The battery comes with a 2 dot (green) charge on the indicator, should I put the battery in and let it run down and do a full recharge OR begin charging it immediately and then let it run all the way to empty and recharge?

• iTunes Sync erasing Exchange calendar / contacts

  - by Garrett

  We have had a handful of instances where corporate iPhone users will be syncing Calendar/Contacts/etc in their iTunes settings, and we would like to prevent this. Unfortunately, when they sync their empty home Outlook calendars it then overwrites everything in their iPhone calendar. This has the unpleasant side effect up "updating" Exchange and wiping out every meeting they have. Luckily, our backups have bailed us out in each case - there seems to be no recovering from it any other way as the data is gone. We prefer to allow our users to continue loading media on their phones, which we believe requires iTunes. Is there a way, through Exchange ActiveSync or iOS mobile management, to prevent this from happening?

• How to keep Varnish cached populate after backend down for an extended period?

  - by Nicholas Tolley Cottrell

  We have Varnish 3.0.2 running on Amazon's Linux and it works great. We have a ttl of 48 hours for most content pages and much longer for images, PDFs etc. This weekend we've taken the backend down for some maintenance, so I upped the ttl to 5 days earlier in the week. I had assumed that anything in cache would continue to be served for up to 5 days, but much to our disappointment we checked varnishstat this morning and the cache was almost completely empty and varnish was serving "page not found" messages. I know that this is not what Varnish is designed to do, but why would it reset its cache when the backend is down? And how can I prevent it for next time?

• Kaspersky processing error Explorer.exe (recycle bin)

  - by aeternus828

  I get daily critical errors from Kaspersky involving Explorer.exe... The file in question is almost always in the Recycle Bin, or something on the desktop. Here is an example error detail: Event type: Processing error Application\Name: EXPLORER.EXE Application\Path: C:\WINDOWS\ Application\Process ID: 2364 Application\Options: C:\windows\Explorer.EXE Component: File Anti-Virus Result\Description: Processing error Object: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\$RIKKQKS Object\Type: File Object\Path: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\ Object\Name: $RIKKQKS Reason: Read error Google searches didn't offer much insight, so I thought I'd ask here if anyone has encountered a similar situation. Not sure if it's a bug, something to be concerned about, or an easy fix, etc. I usually just empty the recycle bin for a temporary fix, but would like to get to the root of the error. Thoughts?
