• Automated Scanning for Corrupted Archive Files

  - by Synetech inc.

  Hi, I have all kinds of files that I have downloaded from everywhere over the years scattered around my hard drives. I’m in the process of trying to organize them all and have run into a problem. Sometimes a file was not downloaded correctly (this was a big issue when Chromium first came out) and is thus corrupt. For media files, this is relatively simple to determine (it requires actually opening and examining the file). For executables or other binaries, it is relatively difficult (executables may or may not crash, other binaries could be completely unknown). Archive files (eg zip, rar, 7z, exe, ace, etc.) however should be pretty simple, they have a built-in corruption detection facility. My problem now is that I really don’t want to open and test each and every single archived file throughout my drive; that would be a nightmare. I’m looking for a utility that can automate the process. Is there a program that can scan archive files on a drive and list the ones that are corrupt? Thanks a lot.

• Make isolinux 4.0.3 chainload itself

  - by chainloader

  I have a bootable iso which boots into isolinux 4.0.3 and I want to make it chainload itself (my actual goal is to chainload isolinux.bin v4.0.1-debian, which should start up the Ubuntu10.10 Live CD, but for now I just want to make it chainload itself). I can't get isolinux to chainload any isolinux.bin, no matter what version. It either freezes or shows a "checksum error" message. I'm using VMWare to test the iso. Things I have tried: .com32 /boot/isolinux/chain.c32 /boot/isolinux/isolinux-debug.bin (chainload self) this shows Loading the boot file... Booting... ISOLINUX 4.03 2010-10-22 Copyright (C) 1994-2010 H. Peter Anvin et al isolinux: Starting up, DL = 9F isolinux: Loaded spec packet OK, drive = 9F isolinux: Main image LBA = 53F00100 ...and the machine freezes. Then I've tried this (chainload GRUB4DOS 0.4.5b) chainloader /boot/isolinux/isolinux-debug.bin Result: Error 13: Invalid or unsupported executable format Next try: (chainload GRUB4DOS 0.4.5b) chainloader --force /boot/isolinux/isolinux-debug.bin boot Result: ISOLINUX 4.03 2010-10-22 Copyright (C) 1994-2010 H.

• install Win7 SP1 with bcdedit failing

  - by Albert

  I'm getting the error 0x800F0A12 which is described here. bcdedit says: C:\>bcdedit.exe Der Speicher für die Startkonfigurationsdaten konnte nicht geöffnet werden. Das System kann die angegebene Datei nicht finden. (English: Couldn't open the start configuration. Couldn't find the file.) (off topic: how can I get those messages in English?) I played around and I assume that is because the system partition C:\ is not on the first BIOS disk. There are 4 disks in my PC. On one of them (shown as the 4th in Windows drive manager) contains Windows, whereby the system-reserved NTFS partition is the first primary and the second primary is my main Windows system partition. A few more partitions follow with other (non-NTFS) stuff. I was able to set the first two disks offline (via the Windows drive manager). For the 3rd disk, it says that it cannot set the BIOS 0 disk offline. How can I ignore that and still install SP1? I don't want to rewire/resetup my disks.

• `:Zone.Identifier` files keep on appearing in Windows XP virtual machine

  - by Jonathan Reno

  I have a Windows XP Home Edition guest and a Linux Mint 13 host. I use VirtualBox and the ~/Public directory is shared with the guest. It sometimes happens that I use IE on the guest system to download files (until I get a better Windows browser). All of the downloaded files go the the L:\ drive (the ~/Public directory). When they are finished downloading, Windows Explorer adds a :Zone.Identifier file for each file I download. When I extract a downloaded ZIP archive on the guest (on drive L:\), Windows creates a :Zone.Identifier file for every file in the extracted directory. This even occurs if I use the host to move a file to the ~/Public directory. The shared ~/Public directory is on an ext4 partition and the colon character is supposed to be illegal in file names in Windows, but not on the ext4 partition. Is there any way to stop Windows from putting all this rubbish on my filesystem? (I might have to create a shell script to clean up after Windows' act.) Here is what I see in Windows Explorer: By the way, if I were running a Mac OS X host (where colons are illegal file name characters) this would be even more horrendous.

• gpg symmetric encryption using pipes

  - by Thomas

  I'm trying to generate keys to lock my drive (using DM-Crypt with LUKS) by pulling data from /dev/random and then encrypting that using GPG. In the guide I'm using, it suggests using the following command: dd if=/dev/random count=1 | gpg --symmetric -a >./[drive]_key.gpg If you do it without a pipe, and feed it a file, it will pop up an (n?)curses prompt for you to type in a password. However when I pipe in the data, it repeats the following message four times and sits there frozen: pinentry-curses: no LC_CTYPE known assuming UTF-8 It also says can't connect to '/root/.gnupg/S.gpg-agent': File or directory doesn't exist, however I am assuming that this doesn't have anything to do with it, since it shows up even when the input is from a file. So I guess my question boils down to this: is there a way to force gpg to accept the passphrase from the command line, or in some other way get this to work, or will I have to write the data from /dev/random to a temporary file, and then encrypt that file? (Which as far as I know should be alright due to the fact that I'm doing this on the LiveCD and haven't yet created the swap, so there should be no way for it to be written to disk.)

• windows 7: Event 55 The file system structure on the disk is corrupt and unusable

  - by Radio

  Here is a real bad one! Windows 7 RTM with SP1 installed [Version 6.1.7601]. Recently tried to delete some folder on my hard drive and Windows prompted "Error 0x80070570: The file or directory is corrupted and unreadable", and at the same time placed an Event 55 describing "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on \Device\HarddiskVolume2." Ran chkdsk, first with /f option, then with /r option. Result in both cases was: no errors found, 0 bad sectors. No problems chkdsk found at all! Went through StackExchange, Google and spent over 6 hours on this. Still cannot figure out the problem. Re-installing/Re-Formatting is not an option! What did I try: Hotfix - Windows6.1-KB982927-x64.msu - gave me an error about incompatibility with my computer, however it totally matches my system. CRC of hotfix was ok. Windows Repair Console found startup errors and fixed those, but this didn't help an issue, even by running chkdsk c: /R from it. http://support.microsoft.com/kb/246026 does not promise anything good. sfc /scannow does not help too. Replaced hard drive by cloning an old one using True Image, repeated all steps above. At the same time, some minor glitches started to appear in my Windows, like side panel and notification area settings are getting reset. Goal is to delete the folder and get rid of Event 55. Sounds like NTFS bug. Please help. This is completely ridiculous.

• How to install Red Hat Enterprise Linux on Apple Macbook Pro MacBookPro4,1

  - by Todd V. Rovito

  I have a one year old Mac Book Pro that I am trying to get RHEL 5.4 installed on via bootcamp. No matter what I do I can't get the installer to boot. I have tried multiple DVD's and even verified the install works on a new Mac Book Pro. Most of the time the installer simply locks up. I usually use Linux text with all-generic-ide on the boot line. I removed the ide parameter and I just used linux text. The results I get are that a bunch of kernel messages appear then the background turns blue and a thin text box pops up saying its loading ata..... something it disappears too fast for me to read. Then the machine freezes. I pressed the alt function keys to see if I could look at the system log, here is what it says: Alt-f3 says "trying to mount CD device hda" Alt-f4 says status error: hda: lastFailedSense Hda: Failed opcode was: unknown Hda: Lost interrupt Hda: Drive not ready for command Ide-cd: command 0x3 timed out Above this junk it looks like it found the partition because it knew it was 20 GB and listed as /dev/sda3. I think it has something to do with the CD drive, is that possible? Thanks again for the support. PS I posted in the apple support forums ( Apple.com Support Discussions Boot Camp Installation and Storage) and didn't get an answer.

• vmdk Recovery after migration from 3.5 to 4 and fallback tentative.

  - by olgirard

  Hy, I've tryed to migrate some VM from my 3.5i environment to a brand new vSphere 4.0 U1. The two platforms are running simultaneously, sharing the same SAN. I Migrate my VM by stopping it, unregistering in vcenter (esx ver. 3.5, i call it esx3), register in vSphere (esx ver. 4, i call it esx4), and migrate upgrade virtual hardware before powering it up (First mistake). vMotion was enabled on esx4, seem to be a second mistake. After a day or so, i encountred problems joigning the esx server (esx4) and decided to unregister my server for esx4 and fallback to esx3. esx3 refused to boot, i supposed this was due to virtual hardware in Version 7 so i recreated a new VM pointing to the vmdk of the old VM. Everithing seemed fine until i log into the server and discover that i was running on the original disk ith every snapshots ignored even those created on esx3. I tried to reboot VM on esx4 but VM doesn't power up because "The parent virtual disk has been modified since the child was created". I've got a copy of a later state of the drive but generated between two snapshots (ovf generated with canverter standalone) as a backup. Do i have a chance to recover at least some files on the virtual drive or (as i tink) all is played, i've done enought mistakes for this time. Thanks for your help.

• Laptop hangs on POST and does not finish except on rare occasions

  - by user1049697

  I have an old Toshiba Satellite A100 laptop that hangs on POST when I try to start it. On rare occasions it does finish the POST and boots Windows successfully, but most times it just finishes it partially and continues to hang. I can enter the BIOS though when it has frozen, but I have to open the DVD-drive first for some reason. The keyboard is not quite right either, and I can't navigate the BIOS properly because the arrow keys doesn't work. I tried an external keyboard, but the problem persisted. I have tried to remove the memory, hard drive, and battery to see if any of these were the problem, but it did not solve it. The one logical thing left to do would be to remove the CMOS battery, but the "brilliant" engineers at Toshiba have place it such that a complete disassembly of the machine is necessary. What this all boils down to is basically the question of whether I can "save" this machine and get it to boot properly, or if I should just send it off to recycling. I suspect it might need costly repairs, but I can't bring myself to throw it away before I have made sure it's completely dead.

• Error when starting .Net-Application from ThinApp-Application

  - by user50209

  one of our customers uses SAP through VMWare ThinApp. In SAP there is a button that launches an .Net application from a server. When starting the .Net-application directly, there is no error. If the user tries to start the application by clicking the button in the ThinApp-Application, it displays the following errors: Microsoft Visual C++ Runtime Library R6034 An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information. After clicking "OK" it displays: Microsoft Visual C++ Runtime Library Runtime Error! R6030 - CRT not initialized So, does the customer have to install some components into his ThinApp (if yes, which?) to get things working? Regards, inno ----- [EDIT] ----- @Sean: It's installed the following way: The .exe of the .Net-Application is on a mapped drive on a server. All clients have the requirements installed (.Net-framework for example) and start the .exe from the mapped drive. The ThinApp-Application tries to start this application and throws the mentioned exceptions. AFAIK there are no entry points for this application configured. What I should also mention is: The .Net-Application crashes during execution. That means, we have a debug mode implemented that shows what the application is doing. The application shows what it's doing and after some steps it crashes. The interesting point is: It's a .Net-application, not a C++ Application.

• Mac OS X Disk Encryption - Automation

  - by jfm429

  I want to setup a Mac Mini server with an external drive that is encrypted. In Finder, I can use the full-disk encryption option. However, for multiple users, this could become tricky. What I want to do is encrypt the external volume, then set things up so that when the machine boots, the disk is unlocked so that all users can access it. Of course permissions need to be maintained, but that goes without saying. What I'm thinking of doing is setting up a root-level launchd script that runs once on boot and unlocks the disk. The encryption keys would probably be stored in root's keychain. So here's my list of concerns: If I store the encryption keys in the system keychain, then the file in /private/var/db/SystemKey could be used to unlock the keychain if an attacker ever gained physical access to the server. this is bad. If I store the encryption keys in my user keychain, I have to manually run the command with my password. This is undesirable. If I run a launchd script with my user credentials, it will run under my user account but won't have access to the keychain, defeating the purpose. If root has a keychain (does it?) then how would it be decrypted? Would it remain locked until the password was entered (like the user keychain) or would it have the same problem as the system keychain, with keys stored on the drive and accessible with physical access? Assuming all of the above works, I've found diskutil coreStorage unlockVolume which seems to be the appropriate command, but the details of where to store the encryption key is the biggest problem. If the system keychain is not secure enough, and user keychains require a password, what's the best option?

• Do you known a reputable backup software that can capture ONLY file system structure + attributes, WITHOUT file content

  - by bogdan

  Is there, on Windows, a reputable backup software out there capable of capturing ONLY a file system's directory and file structure, along with each item's attributes, WITHOUT capturing the actual file content (all files should be zero-length in the backup). I thoroughly searched the web for a solution and wasn't able to find one. Scenario when this would be very useful: I have a large drive with a huge amount of files. If the drive dies, I don't care so much about the content in these files (I can always download this content again from the Internet at any time) but I do care HUGELY about the names of the files that were on it, possibly also about their MD5 hashes and other classic file attributes (especially created-date / modified-date). The functionality I need is present to an extent in "media"/file cataloging software (i.e. whereisit) and, to a lesser extent, in a Total Commander set of extensions (DiskDir, DiskDirExtended). The huge drawback with cataloging software is that it's not designed to store previous versions of each item (AFAIK) and, most importantly, it has very weak content backup capabilities. I managed to think of a hack but I hope there's some backup software out there that already has this capability and I just failed to find it, thus this question. The hack: RoboCopy could be used with /CREATE (CREATE directory tree and zero-length files only) or /COPY (what to COPY for files) without the D=Data flag, to clone a directory structure into one where all files are zero-length but have the desired attributes. Then I would backup the cloned directory structure with a reputable backup software. I would really love to avoid a hack like this one, if possible. Thanks, Bogdan

• Looking for suitable backup solution Mac OS X to offsite Centos 6 server 1TB of working data

  - by Brady

  I'll start by saying what we have in place currently: On site file server (Mac OS X Server) that is used by GFX designers and they have a working 1TB of data. Offsite server with 2TB available storage (Centos 6) Mac OS X server rsync data to offsite server every 6 hours (rsync -avz --delete --progress -e ssh ...) Mac OS X server does full data backup to LTO 4 tape on a 10 day recycle (Mon-Fri for 2 weeks) rsync pushes about 60GB of file changes a day. The problem: The onsite tape backup is failing as 1TB of graphics files don't compress well to fit onto a 800GB LTO4 tape. Backup is incredibly slow doing a full backup. Pain in the backside getting people to remember to change the tape. Often gets forgotten etc The quick solution: Buy LTO5 Drive and tapes. However this has been turned down because of the cost... What I would like: Something that works in the same way rysnc works. Only changed data is sent over the wire and can be scheduled to run multiple times during the day. Data that is sent is compressed and sent over SSH. Something that keeps a 14day retention but doesn't keep duplicate data So as an example if I have 1TB of working data and 60GB of changes are made each day then I expect around 1.84TB of data to be stored on the offsite server. To work with the Mac OS X server and Centos 6 server. Not cost an arm and a leg. Must be a cheaper solution than buying an LTO5 drive with tapes (around £1500). Be able to be setup to run autonomously. Have some sort of control panel that will allow an admin to easily restore a file/folder. Any recommendations?

• Coffee spilled and went inside CPU...computer not starting

  - by Harpreet

  Today coffee got spilled over my table, and some of it (very less) reached the CPU placed under the table. I think little bit of it got inside the CPU through the front face of the CPU. As that happened the fan started running very fast and made noise. I tried to restart to see if it becomes fine, but the computer didn't start again. First it gave an error of "Alert! Air temperature sensor not detected" and didn't start. Next I tried again multiple times of starting the computer but then it gave some memory error. I was not able to start the computer. Incase there's a problem in hard disk or something related to memory, is there any way we can extract our work or data? I am scared if I am not able to extract my work in case some problem occurs like that. What options would I have? Help! EDIT: I have attached the photo here and you can see the area spilt in red circle. The hard drive electronics have been affected and internal speaker may also have been affected. Any advise on cleaning and if hard drive can work? EDIT 2: Are there any professional services offered to extract data from blemished hard disk, like this one, in case I am not able to run it personally?

• PC only boots from Linux-based media and won't boot from DOS-based media

  - by Xolstice

  I have this problem where the PC only seems to boot from a floppy disk or CD if it was created as a Linux-based bootable media. If it was created as a DOS-based bootable media the system just freezes at the starting point of the boot process. I originally asked this under question 139515 for CD booting only, and based on the given answers, I was under the impression the problem was with the CD-ROM drive; however, I have since installed a newly purchased CD-ROM drive and the same freezing occurs. This then made me try the DOS bootable floppy disk approach and I was quite surprised that it exhibited the same freezing problem. I then tried try a Linux bootable floppy and everything booted from it without any issues. As I mentioned in my original question, the PC was booting just fine from the DOS-based bootable CD, and then it suddenly decides to pull this freezing stunt. I can't remember if I changed anything in the BIOS settings that may I have caused the problem, but I am wondering if that could be the case - it is currently using the Award Module BIOS v4.60PGMA. Can anyone help?

• SSD causing 100% CPU usage in Apache/PHP

  - by Tim Reynolds

  I wanted to increase the performance on my development laptop so I added an Intel 320 Series SSD as my primary drive. Everything is amazingly fast, as expected, except Apache/PHP. I develop Magento by using an Ubuntu 10.10 virtual machine. Information: Host OS: Win 7 Professional 64bit Guest OS: Ubuntu 10.10 32bit Processor: i7 Chipset QM55 SSD: Intel 320 Series 160gb 30% full HDD: Hitachi 320gb 50% full (in side bay using an adapter) Laptop: Lenovo T510 Using: Shared folders Apache Version: 2.2.16 PHP Version: 5.3.3-1 APC Version: 3.1.3p1 APC Memory: 128M Using tmpfs for cache, log, session directories in Magento In the VM running on the SSD (VM files and source files are on the same drive) loading a product page in the Admin takes on average 26.2 seconds and uses 100% CPU for nearly the entire time. In the VM running on the old HDD loading the same page takes on average 4.4 seconds. It mostly uses around 40-50% of the CPU while rendering the page. I have read this post: Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)? It says to change some settings in the bios. I have turned any and all power management features off in the bios. I can't for the life of me understand why this would be happening.

• How do I delete hardlinks, symbolic links, junction points, etc please?

  - by jonny

  I could be wrong, but I'm yet to hear a valid argument for the exploitability that these things deliver...outweighing their very dubious / debatable functionality. They seem to me to be marginally handy, but I don't think I have any need for them. I do have a need for security, however. How can I delete their entire functionality permanently from my hard drive, please? Microsoft only has pages on how to create them; which seems almost peculiar to the point of being dubious (at least, to me...) And just a dumb command line question, am I correct in assuming fsutil hardlink list c: will enumerate every single hardlink on that drive? C:\Windows\system32>fsutil hardlink list c: \Windows\System32 Also, how do I delete symbolic links please ;) But I'd just rather have all symbolic linking and recursion-creating stuff removed, if that's possible? C:\Windows\system32>fsutil behavior query symlinkevaluation Local to local symbolic links are enabled. Local to remote symbolic links are enabled. Remote to local symbolic links are disabled. Remote to remote symbolic links are disabled.

• Windows, why 8 GB of RAM feel like a few MB?

  - by Desmond Hume

  I'm on Windows 7 x64 with 4-core Intel i7 and 8 GB of RAM, but lately it feels like my computer's "RAM" is located solely on the hard drive. Here is what the task manager shows: The total amount of memory used by the processes in the list is just about 1 GB. And what is happening on my computer for a few days now is that one program (Cataloger.exe) is continually processing large quantities of (rather big) files, repeatedly opening and reading them for the purposes of cataloging. But it doesn't grow too much in memory and stays about that size, about 90 MB. However, the amount of data it processes in, say, 30 minutes can be measured in gigabytes. So my guess was that Windows file caching has something to do with it. And after some research on the topic, I came across this program, called RamMap, that displays detailed info on a computer's RAM. Here is the screenshot: So to me it looks like Windows keeps in RAM huge amounts of data that is no longer needed, redirecting any RAM allocation requests to the pagefile on the hard drive. Even when I close Cataloger.exe, the RamMap reports the size of the mapped file as about the same for a long time on. And it's not just this particular program. Earlier I noticed that similar slowdown occurred after some massive file operations with other programs. So it's really not an exception. Whatever it is, it slows down the computer by like 50 times. Opening a new tab in Chrome takes 20-30 seconds, opening a new program can take up to a minute. Due to the slowdown, some programs even crash. So what do you think, is the problem hiding in file caching or somewhere else? How do I solve it?

• How to restore windows.old for windows 7

  - by Jim Thio

  I reinstall windows. Then I regret that and want to go back. Fortunately the old windows is stored at windows.old I follow the instruction in http://support.microsoft.com/kb/971760 I did it all with small catches When I insert the windows 7 installer, the drive for installer is X and my hard disk is D rather than C. However, on normal windows operation the drive is C. Only when I boot through CD the partition is assigned to the letter D. There is no file bootsect on my windows installer So I can't do **D:\boot\bootsect /nt60 c:** Which should be changed to X:\boot\bootsect /nt60 C: or X:\boot\bootsect /nt60 D: depending on what it really does. As I said if I boot through windows dvd my hard disk letter is D but normally it's C. I am not even sure what that bootsect does anyway. I also can't do this one Attrib –h –s –r boot.ini.saved Copy boot.ini.saved boot.ini There is no file boot.ini or boot.ini.saved It's hidden but I don't see it if I try to look unhidden files either. Because I simply switch from windows 7 to windows 7 and the directory for windows don't change c:\windows I thought it should still work. Well, it doesn't. When windows restart it only goes to the logo and then restart the computer.

• How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

  - by sauparna

  I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

• Dell 2970 - HP 1/8 G2 autoloader keeps falling off LSI 2032 SCSI chain

  - by middaparka

  I've a somewhat irritating problem with a Dell 2970 that has a HP 1/8 G2 autoloader (the Ultrium LTO 2 model) attached to the Dell/LSI 2032 non-RAID SCSI card. In essence, sometimes the autoloader/drive completely fails to appear on the SCSI chain (i.e.: there's neither a media changer or tape drive present within the device manager) and sometimes it appears but then subsequently disappears at a seemingly random (yet always inconvenient) time, resulting in backup failures. On most occasions, there are simply no errors logged in the system event log, but I did manage to capture a series of LSI_SCSI event ID 11 ("The driver detected a controller error on \Device\RaidPort0") errors followed by an event ID 129, ("Reset to device, \Device\RaidPort0, was issued") error during testing. I've tried two different cables, both with the same effect – sometimes the autoloader appears (for a while), sometimes it's completely absent. There's only one terminator I've tried to use, but as I've since successfully tested the autoloader on multiple occasions (albeit via a Adaptec U160 card on a different machine), my gut feel is that the issue doesn't lie with the terminator, or indeed the autoloader itself. As such, I'm just wondering if anyone has any ideas? It's most likely not relevant, but this is all under Windows SBS 2008, running Backup Exec 12.5 SBS edition (the Dell version), both fully patched. Addidtionally, the autoloader is running the latest firmware. It's been a while since I've dealt with anything SCSI, so all suggestions will be gratefully, gratefully received.

• Damaged partition after disk image

  - by Charles Gargent

  I am trying to clone/backup a disk with Windows 7 Pro 64bit on it. First I tried Easus Todo Backup and used disk clone option without sector by sector copy. I then plugged in the new drive and I get the following error. "Invalid or damaged Bootable partition" I then plugged the old drive back in and I am greeted with the same error. My next step was to try the sector by sector disk clone, but still I get the same error. I have tried fixing the mbr with the windows disk but that makes no difference. I have tried some other free tools and I get the same error. I have tried this on a different machine running Windows 7 Enterprise 32bit without this problem. I have done some searching and the only thing I can come up with is this post from the Acronis forums http://forum.acronis.com/forum/8254 suggesting that the bios is reading my disk geometry incorrectly. Can anyone shed any light on this, is there a way I can fix this either in the bios or repair the mbr every time I reimage it?

• Asus MyCinema U3100mini Choppy

  - by dsimcha

  I'm running an Asus MyCinema U3100mini ATSC on Windows 7 64-bit. When I play live TV in Windows Media Center, it's very choppy and uses 500+ MB of RAM, I'm guessing due to the hard drive buffering functionality. Is there any way to disable the live TV pause buffer completely? If not, can anyone recommend alternative software that: Works with the MyCinema. Is lightweight and not horribly bloated with features I'll never use like Windows Media Center is. Edits: This is a dual boot system. I've discovered that the tuner actually works fine on XP. It also works fine on my other computer, which has slower hardware and also runs Windows 7 64-bit. The problem actually seems to be with playback at large screen sizes, not with hard drive buffering. Everything works fine below a certain window size and fails for large windows or full screens. Also, the same thing seems to happen whether playing live or recorded TV. As far as the obvious stuff goes, I have the latest video drivers from ATI for my Radeon x1050.

• How can I change the default location/action of 'Open Outlook Data File' in Outlook 2010?

  - by Chadddada

  I have recently deployed a Remote Desktop Host server that functions as a remote Microsoft Office 2010 work space for users. In part of the locking down of this server I have installed all programs on the D: drive and, through the use of Group Policy, hidden all the drives on the server from standard users. In addition to hiding these drives I am not allowing users to save anything locally (on the server) or open Libraries. However one of the functions of the server is to provide the Outlook client. Often users will have the .PST file stored on a network location and want to open this in Outlook. Can I change the default action or location that File Open Open Outlook Data File looks or tries to pull the file from? The default location seems to be under Users / Libraries. When click 'Open' you get a warning: This operation has been cancelled due to restrictions in effect on this computer. Clicking OK drops the user into a small menu that shows attached network drives under Computer. Can I instead have the 'Open' click drop the users in a defined network drive or just open computer and allow them to select a share? I don't want them to see the error message. A solution that looks to have been used for Office 2000/03 is: Key: HKEY_CURRENT_USER\Software\Microsoft\Office\<version>\Outlook Value name: ForceOSTPath Value type: REG_EXPAND_SZ Value: path to your storage folder I am not sure if there is a better way to do this now OR if this even works with Office 2010.
