• CPU not working on a specific motherboard

  - by Shaman

  I'm making a computer for someone and I met a weird problem. The CPU that I have doesn't work on this motherboard. The CPU is an Intel Pentium D 925 and the motherboard is an ECS G41T-M6, which in theory should work together. The only thing reused is the power source(400W). When I start the computer, the fans start, and that's it. The BIOS doesn't boot. I tried my own power source (600W Corsair) and nothing. Removed the RAM, no warning. In desperation I tried the last thing, swaped my own CPU with this one (Core2Duo E7200). Lo and behold, it worked. Both. The Core2Duo worked on the ECS with the old power source and the RAM that I used in the first place, and the Pentium D worked on my Gigabyte G31M-ES2L. What I discovered was that the Pentium D didn't receive power on the ECS, because I tried running it without the cooler and it remained at room temperature. On a side note, I also removed the HDDs just in case. So, in conclusion, any ideas? I can't return it, and I can still use it to upgrade another PC, but I would really prefer not to buy another CPU if possible.

• My bios datetime is resetting to 2002, what should I do?

  - by Thierry Lam

  I bought my PC brand new in mid-2006. I'm currently dual booting Win XP 32 bits and Ubuntu Karmic Desktop. Over the last few days, when I boot up my computer, it tells me that my bios time is not set. I now have 2 choices for booting in: Windows first: I can safely get into Windows but the date now shows 2002/01/01 at 00:00. From there, Windows will not sync its time to its servers, I have to manually advance the date myself. I can also advance the date from the bios at startup. Ubuntu first: Since the time date is still set at 2002, the boot system cannot find my linux partition. I can fix that issue by booting to Windows, set the date properly and the linux issue will be fixed automatically. The above two issues can also be fixed if I manually set the bios date/time manually when I turn on my computer. It's annoying to do that every single day since I shut down my PC daily. Am I having an OS issue or a hardware issue? How can I resolve this problem?

• Microsoft Mouse and Keyboard Center - Slow response for App-specific shortcuts

  - by Darrel Hoffman

  So a few months ago, I bought a new MS mouse, and was surprised that they'd discontinued Intellipoint in favor of this Microsoft Mouse and Keyboard Center. It seems to have the same functionality underneath all the bloat, but there's a very serious drawback - when I set up application-specific functions for the extra buttons on the mouse, they work, but sometimes with a very long delay, like up to a minute or more. For example, I often set up the left side button as an "Undo" in various programs for convenience. But sometimes, when I try to use that Undo button, nothing happens, so I'm forced to use the standard Ctrl-Z or whatever. But then, a minute or so later, it suddenly remembers that I hit that button a while back, and calls the Undo unexpectedly on something entirely different. It's infuriating. No modern computer function should be this slow. It's not the software or the computer itself, because doing an Undo via Ctrl-Z or the menu still works instantly. It's very definitely a side-effect of delayed response to the mouse button. Usually after it delays the first time, it'll work quickly after that, but if you haven't used a given shortcut in several minutes, it "forgets" again and you get another inexplicably long delay. Intellipoint never had this problem, but it's not supported any more, and not compatible with the newer mice. Has anyone else noticed slow-downs with MS M&K C and app-specific shortcuts? Any ideas how to get around this? I use these shortcuts extensively in my workflow and it's just entirely unacceptable to have such a long delay in what should be a pretty basic feature.

• lenovo x1 carbon windows 8 frequent wifi disconnect issue

  - by hIpPy

  I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop. I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter. Once I get disconnected, I try below to connect again in that order: turn Airplane mode on and off, troubleshoot network problems windows troubleshooter), restart the laptop I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop. A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help. Windows 8 is updated. None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected. config: Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter) Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200] x64-based PC LENOVO System Model: 3443CTO X1 Carbon Touch I recently noticed this log message When I got disconnected in event viewer: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX]. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server. Any idea?

• How to migrate Outlook Express mail rules?

  - by ronwest

  I have a home computer that only had a 15Gb C: drive, and ran out of space with all the Microsoft Updates, etc, that keep coming down. So I fitted a 160Gb drive as a C: drive and altered the drive jumpers to make the old C: drive into a slave D: drive, to save migrating documents, etc. I've installed a clean copy of Windows XP SP3 and reassigned the new Outlook Express' mailstore path to point to the old mailstore folder that now has a D: drive letter - and it all works OK. However, my extensive list of mail rules have not been transferred to the new OE and I have not been able to identify how they are stored. To find it I added a new rule to the new OE, exited OE, then searched on the whole computer (including hidden/system files) for files altered around the time I added the rule. I hoped I could just overwrite a new empty file with an old one. But the only files that seem to be changed are Windows system-level files and some bits and pieces in the Windows\PreFetch sub-folder. None of them can be opened as XP has them locked, and none of them have names that are anything to do with email or rules. Does anyone know of any way of migrating OE rules, or do I have to re-enter them by hand? Thanks!

• Toshiba A205-5804 freezes when plugged in

  - by heron

  Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheating problem, the computer is not getting hot or anything related, I've already tried changing the AC adapter, booting only with AC and no battery, and also all of these suggestions: Try changing the following setting in the bios setup, under the 'Advanced' tab Dynamic CPU Frequency: Mode = Always Low (NOT DYNAMIC) My laptop has been running on AC power without a problem for 24hours, including many restarts, and when I went back to the original bios setting, the problem returned almost straight away. EDIT Other suggestions I found on the web from here and here: Set the power plan to high performance Set the power plan to "Minimal Power Management" (1 and 2 do conflict) Start - Control Panel - Device Manager -- Processor - disable one of two processors - reboot normally 4.Do this: Only plug battery into laptop Turn on the laptop and start Windows normally Plug AC adapter into laptop, the screen will freeze Leave the laptop the way it is for 12-24 hours After 12-24 hours, turn it off the hard way Once it is turned off, turn it back on. The laptop is working now. I have no idea of what can it be...

• Can a non-redundant RAID5 cause any serious problems (compared to RAID0)?

  - by leemes

  I used to have a three-disc RAID5 (mdadm) in my computer for personal media storage (music, videos, photos, programs, games, ...). It had three discs with 750 GB each, resulting in an array capacity of 1.5 TB. One day (one year ago), I needed one of those discs to install another operating system. I thought, I don't need the redundancy anymore since I backup the most important stuff (personal photos e.g.) on an external disc anyway. So I decided to remove one of the three discs without converting the RAID to RAID0 or even two separate discs, because I had no temporary storage (since one cannot simply convert the RAID5 to RAID0 AFAIK). So now, for about one year, I have a non-redundant RAID5 with 2 of 3 discs running. Sometimes, one of the discs has a defective contact at the power cable or something similar causing the drive to stop working temporarily (I don't know exactly what it is). Since it still works when rebooting the computer and in most cases by calling some mdadm commands, it wasn't that problematic. Note that the data is not very critical, since I still have a backup of the most important stuff. But in the last few weeks, one of the drives fails very frequently (every few hours), so it gets really annoying to manage this. My questions are: Is there any disadvantage (apart from the annoying management) of a non-redundant RAID5 (with one drive less than typical) over a RAID0? If I understand it correctly, both have no redundancy and the same capacity. On a temporary drive failure, I can restart the array in both cases, assuming that the drive itself still works after the failure. Can it happen that the drive contents alter on a drive failure, making the array inconsistent? If so, can I tell mdadm to check the array for failures (without a file system level checking tool)? Since the drive most probably only has a defective contact causing it to fail for a second only, can I tell mdadm to automatically restart the array, so I will not even notice the failure if no application wanted to access the file system during the failure?

• Looking for easiest, most simple solution to run a customised DNS Server for my local network on Windows 7.

  - by Jamie G

  I need to forward some websites, such as http://testing.server/ to an fixed IP address on my local network. I can do this easily on one computer using the hosts file. However, I need this to work for all machines on my network. I think the best way to do this will be to setup my own DNS Servers and add the custom DNS settings there. However, I'm looking for the simplest way possible to do this - I really don't want to spend hours setting up Unix Servers and running tricky terminal based scripts just to do this! My server is a standard Windows 7 machine. My dream would be a nice simple windows program with a GUI where I could input my ISP's DNS server and it would use those records, unless I had specifically set up my own DNS for a domain to use instead. If it had a web based admin system that was accessible from another computer on the network that would be even better. Does anyone know of anything that can do this? Many thanks indeed.

• Host system resets (crashes) when using VMWare or VirtualBox and 64-bit guest systems

  - by sinni800

  I have been trying to install virtual systems on VMWare for a while now and encountered strange behaviour from my PC. The behaviour is as follows: On "automatic" virtualization mode it either outputs a cryptic error message (can MAYBE give later, if I can reproduce) right on startup (before even the BIOS) or it resets the complete HOST system (blackscreen, bios...) If I install a Windows XP on it it works well on "binary translation" mode. If I try installing Linux on it, in "binary translation" mode it crashes 1 or 2 seconds after I hit enter on the GRUB selection screen (after the first page of kernel messages rolled in) Using VirtualBox it crashes right in the BIOS. It gave me a Bluescreen though! 0x00000101: CLOCK_WATCHDOG_TIMEOUT: a clock interrupt was not received on a secondary processor within the allocated time interval NEWS: I tried VirtualBox again and it did not completely crash the computer this time. It gave me a critical error and a log file: http://pastebin.com/yKZSDs91 In conclusion, it will crash instantly if VT-x is activated. If not, it seemingly only crashed if I try to install something with 64 bits. Another update: Yes, it ONLY crashes when the guest is 64 bit! What I tried: Reinstalling Windows (my Windows installation was quite broken so it seemed natural. Didn't work though.) New BIOS What I am certain of: Virtualization extensions are activated in the BIOS What my computer specs are: ASUS P8P67 LE mainboard, newest BIOS/EFI firmware Intel Core i5 2500k Ati Radeon HD 5770 16 GB Corsair 1333mhz DDR3 RAM, 4 X 4 GB

• Using Active Directory through a Firewall

  - by Adam Brand

  I had kind of a weird setup today where I wanted to enable Windows Firewall on a Windows 2003 R2 SP2 computer that would act as an Active Directory Domain Controller. I didn't see one resource on the Internet that listed what would be required to do this, so I thought I'd list them here and see if anyone has anything to add/sees something that isn't necessary. Ports to Open with "subnet" scope: 42 | TCP | WINS (if you use it) 53 | TCP | DNS 53 | UDP | DNS 88 | TCP | Kerberos 88 | UDP | Kerberos 123 | UDP | NTP 135 | TCP | RPC 135 | UDP | RPC 137 | UDP | NetBIOS 138 | UDP | NetBIOS 139 | TCP | NetBIOS 389 | TCP | LDAP 389 | UDP | LDAP 445 | TCP | SMB 445 | UDP | SMB 636 | TCP | LDAPS 3268 | TCP | GC LDAP 3269 | TCP | GC LDAP Ports to Open with "Any" Scope (for DHCP) 67 | UDP | DHCP 2535 | UDP | DHCP ALSO You need to restrict RPC to use fixed ports instead of everything 1024. For that, you need to add two registry keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters Registry value: TCP/IP Port Value type: REG_DWORD Value data: <-- pick a port like 1600 and put it here HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters Registry value: DCTcpipPort Value type: REG_DWORD Value data: <-- pick another port like 1650 and put it here ...don't forget to add entries in the firewall to allow those in (TCP, Subnet scope). After doing all that, I was able to add a client computer to the AD domain (behind Windows Firewall) and log in successfully.

• Routing for remote gateway over VPN in Vista/7 broken?

  - by Raymond

  Hi, Situation is as follows. Home computer running Windows 7, sets up VPN connection (LT2P + IPSec, "use remote gateway" disabled) to office. Subnet is 192.168.64.x Office has Draytek Vigor 2920 router, subnet is 192.168.32.x What happens? - VPN connection itself works fine - Can ping any machine on the remote network - When trying to open a webpage from a host in the remote network, the remote server logs the incoming request, but the browser hangs on "waiting for..." and eventually times out. I have observed this problem on Windows Vista and Windows 7. On Windows XP however there is no problem like described above. The only clue I have is that there is a difference in the routing between XP and Vista/7. The output of "route print" on Windows XP looks like this: (See www.latunyi.com/routing_xp.png) So here the gateway for the 192.168.32.x subnet is the IP address that the local computer has in the remote network. The output of "route print" on Windows 7 (and Windows Vista) looks like this: (See www.latunyi.com/routing_win7.png") Now the gateway for the 192.168.32.x subnet is the IP address of the VPN router (32.1). I don't know if that causes this trouble, but it seems a bit strange. Enabling "use default gateway on remote network" doesn't make a difference. Using the new option "Disable class based route addition" in Windows 7 only makes the route to the VPN router disappear. I am really puzzled here. I assume the VPN routing can't be broken in both Vista and Windows 7, and this should just work without manually adding routes. I hope someone has a solution for this problem :-). Thanks!

• Symantec Antivirus Corporate -- two problems

  - by Alex C.

  We have a Windows network with a domain and about 50 clients. A few months ago, we installed Symantec Antivirus, Corporate Edition ver. 10.1.8.8000. There are two problems. The larger problem is that the software isn't very good at stopping viruses. In the last month, four different machines have become infected with those viruses that masquerade as antivirus software. Two machines I was able to clean with MalWareBytes. The other two were hopeless, and I had to reinstall Windows. Is there something I can do to make the Symantec product more effective? As far as I can tell, it successfully updates definitions nightly and pushes the definitions to the clients. The smaller problem is that the Symantec client applications sometimes initiate scans at random (and inappropriate) times. One of my co-workers complained to me yesterday that her computer was running very slow. I looked at the scan history and found that Symantec had scanned the computer three times during the past two days, and each time during the workday. No threats were found. Not sure why it's doing this, but I'd like it to stop. Any help would be appreciated. Thanks.

• Video card not detected in POST on initial boot.

  - by Jeff M

  I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

• How can laptop keyboard keys be removed and replaced?

  - by Lord Torgamus

  I'm trying to fix a laptop keyboard that has issues with keys on its left side. Just by feel, it's clear that something sticky got under there. There could be something crunchy too, but that might just be the sound of the key's spring releasing itself from the sticky. I don't know the cause because it's not my computer and the owner isn't sure, but I'm guessing soda spill for now. The computer is an HP dv2500. I've removed the keyboard and blown under it but that hasn't helped. I didn't use compressed air because I just don't have any available, but I suspect it wouldn't help with sticky. So, I'd like to pop they keys off and clean with damp cotton swabs or similar. Is there a proper way to remove the keys? I've found some instructions via Google for non-laptop keyboards, but they don't seem like they'd work for me. Alternate solutions to the problem also welcome, but I've been curious about how to remove the keys for some time for other reasons.

• Active Directory problems while trying to perfom compare operation

  - by Alex

  I have CentOs 5.5 with Apache 2.2 and SVN installed. Also I have Windows 2003 R2 with Active Directory.

• How is network mounted software executed?

  - by CptSupermrkt

  I would like to understand how network mounted software works. For example, at my place of work, we have a software server. Each client machine (hundreds of them) automatically mounts directories from the software server on boot. For example, a program like Matlab is installed just once on the software server, but each client machine can start up an instance of Matlab. What is going on under the hood? Let's say I run /opt/bin/matlab and /opt/ is mounted from the software server, what happens when I press Enter to execute matlab on a client machine? The process is on the client machine, and I've already narrowed down that there isn't any implicit or hidden file transfer (i.e. copying matlab to my machine temporarily for that session) by running matlab on a computer with nearly zero disk space (i.e. not enough room to transfer). Since Matlab was installed on the server, how is my client computer executing it? What mechanism is controlling this? What is happening behind the scenes?

• iTunes copy just metadata (song and album ratings, playlists) from iPod

  - by Jared Updike

  I have an iPod touch that I synched with my Windows computer (iTunes 9.0 I think) until my harddrive failed and I lost my entire library. I rebuilt the library (songs) from a year old backup (and various other source for songs) but my playlists and ratings are of course a year old. My iPod itself has most of the playlists and ratings I care most about (favorite songs and albums, rated 4 and 5, for example). I have a catch 22 situation where I feel nervous that I haven't backed up my iPod in around 4 months (when my drive failed) so I'd like to back it up as soon as possible... but if I back it up I have to clear all the songs and playlists and copy them back, which I can't really do since I need to rebuild my playlists on my computer first (using the data only available on my iPod!) The question: is there a better way to READ the information off my iPod than doing it manually, song by song and album by album and playlist by playlist (XML, text dump, database, spreadsheet, anything). In other words, mostly I want the information (metadata like ratings and playlists, not songs) copied off the iPod so I can more quickly get my iTunes library ratings and playlists re-built (manually) so I can finally wipe the music and back up my apps, etc. Then I'd like to copy the music back immediately. The part I'd like to avoid is manually navigating everything on my iPod to read through all the playlists and ratings (50 GB, 6,000+ songs) as I re-enter all of that data by hand. I've done a few dozen albums and it's pretty time consuming having to tap around on the iPod. Reading from a spreadsheet (for example, or XML which I could write a script to get into spreadsheet form) would probably help tremendously, plus then I'd have a backup of that information somewhere besides just my iPod.

• Network Sharing Issues

  - by Mark Kramer

  I have two computers I want to have on a network share together (so the laptop can print through the desktop's printer). These are both connected to the same router. (One wired and one wireless) And they both have the same workgroup name. However, when I type "net view" in the command prompt, the only computer that shows up is the computer I type the command into. How do I get these computers to be shared with each other? Update: The tower is running Windows XP, the Laptop is running Windows 7. I have disabled the Firewall on both until I get this set up. Update 2: Typing the command net view on my desktop is acting very strangely. Noe sometimes it only shows itself on the list of computers, sometimes it shows itself and the laptop and sometimes it doesn't work at all and displays system error 6118. I typed net view into the command prompt on the Windows 7 laptop and both computers showed up, so I went to connect to the desktop from the laptop and it said the dekptop could not be found, even though it is showing up int he list of shared computers. Here are supporting pictures (these are coming from the laptop)

• CD Drive not discovered

  - by user1009073

  I have a self built computer. it uses a P6T Deluxe motherboard, which has both SATA and IDE ports. This was built several years ago, and had an IDE CD/DVD drive. This drive started going bad (would not burn CDs correctly), so I decided to replace it. I had difficultly finding an IDE DVD drive, so I bought a SATA DVD drive. I opened the comnputer, took out the old DVD drive. I left the IDE cable in place, connected to the motherboard, but it is not connected to any drives. I hooked up the new DVD drive, both power and with a SATA data cable (SATA port 3 if I recall). (Sony Optiarc 24x , Newegg URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16827118067 ) When I power on my computer, the drive does NOT show up in Explorer. I can hit the DVD eject button, and the drive will open up, so I know it at least is getting power. I thought, maybe something in the BIOS. When I go to BIOS, boot devices, it shows (1) floppy, (2) my hard drive (3) ATAPI CD Drive. The only other possible BIOS option I could find was uder 'Storage Configuration'. Configure Storage as: My setting is RAID, since I am using two drives in a RAID configuration. Other options were IDE and ACHI. Other than trying to find an IDE DVD drive, is there anything else I can try? The drive does not show up at all in Windows Explorer. I did put in a CD thinking that might help, but nothing happened. Thanks, GS

• Windows 7 Media Center: sometimes no sound on a TV channel

  - by torbengb

  Problem Sometimes, recorded TV shows have no sound. This is of course very annoying because the recorded show is worthless. Also, when switching channels while watching live TV, sometimes a channel has no sound. This is always solved by switching channel again and then back (most often, once will do the trick). Media Center doesn't do this trick by itself when recording of course, so that's the bigger issue - but the cause is certainly the same. Details The computer is running a newly installed Windows 7 and Windows Media Center. It has 2 different tuner-cards installed. Both are installed with signed and up-to-date Win7 drivers and appear OK in Device Manager. Both tuners get the same antenna signal, from a split cable from the wall. The cable delivers analog cable TV (40+ channels) and digital cable TV (4 channels) at the same time. Both tuners have been configured to receive both analog and digital channels. This only happens with analog channels. How can I fix the no-sound problem? Update: I've now spent some time with the computer to try and pinpoint the problem, but I've had little success so far: I flipped through the channels until one didn't have sound, then I disconnected the antenna cable from one of the tuners. It was the right one because then the video also went away. I flipped lots more channels to see if the other card also would come up mute once but I never had a channel without sound. It might still be possible, I don't know. Then I disconnected the "good" tuner and connected the "bad" tuner and again flipped lots of channels but again I never had a channel without sound. It seems to me that the problem is erratic. It happens on any channel, and I haven't ruled out yet that it only happens on one tuner.

• Notebook display problem (multiplication)

  - by SubniC

  Hi, I'm having some troubles with the display of a LG E500 notebook. The thing is that without any known reason the display starts to show the screen divided in eigth parts and each part show the display image as if I had a matrix of eigth displays :) I thought it could be some kind of refresh rate problem or driver related, but it is happening at boot-up as well and the BIOS. I got the computer completely unassambled yesterday and I check all the wires and connectors looking for something broken or unconected, but without luck... You can see a picture here of the problem (sorry for the low quality, but I think it illustrate the problem. EDIT 1: I uploaded a new pictrue, here you cans ee the problem better :) There are three horizontal lines that you can see just between the windows. You can see the grey line at the first moment you turn on the computer and the after the duplicated screens show up just like if they where arranged over a grid (over the horizontal lines...) I hope it makes any sense. Do you know what could be happening? or can you tell me what would you do? Thank you very much for your help.

• Is it possible to trace someone using Google during an online exam?

  - by George

  I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?

• Looking for advice on using dd to backup a dual boot laptop.

  - by AvatarOfChronos

  My questions boils down to this. If I do "dd if=/dev/sda of=usbdrive" can anybody confirm that this will get everything including mbr/partition information/all four partitions and create a drive that I can swap with the failing internal drive without losing anything? If this is done while the computer is running will it still copy everything? At this point I'm afraid to shutdown the computer for fear of it never starting again. Secondly, how tolerant is dd of failing drives? Has anybody used it to recover a half dead drive before that can share any potential pitfalls? Did it get the data ok or is this going to be a hope for the best kind of situation? And lastly, If the usbdrive is larger than the failing internal drive I'll still be able to expand the partitions later so I'm not losing space? this last part seems silly to ask but with my current streak of bad luck I'll end up overwriting some magic bit and forever turning a 640gb hdd into a 500gb hdd. Also if anybody has a better solution to create a complete clone that gets everything I'm all for hearing about it. PostScript: I had been making periodic backups however when whatever miasma that killed the laptop struck it also got the NAS :( Post PostScript: both devices were on a UPS system.

• Installed Windows 7 Ultimate on D Drive and previous Windows 7 Enterprise on C Drive has stopped starting up

  - by teenup

  Please please help! I have installed Windows 7 Ultimate on same hard drive on D Drive on my laptop and the previous Windows 7 Enterprise which was installed on C Drive is not booting up now. When I turn on my laptop, I see two Windows 7 on the screen, when I select newer one, it starts, but when I select older one which is Enterprise edition, system won't start and I get the DOS black screen with this error message: Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: Insert your Windows installation disc and restart your computer. Choose your language settings, and then click "Next." Click "repair your computer." Info: The boot selection failed because a required device is inaccessible. I notice that when I run the newer OS installed, the previous OS's drive (Which is D: now instead of C:) has become unusable and when I double click it, it asks me to format the drive. The data, that I had on my D Drive (Which is now C Drive for new OS), I had copied it to a network path and it is available. It was containing Windows 7 Users folder which I copied at that time when installing new windows. I have copied that Users folder again to the new OS's C Drive thinking it would run again, but of no use. Please please please...if someone can help...It is extremely required for me. Thanks a lot in advance.
