HiMy problem is that a CHKDSK is carried out on Drive K: (which is a data drive/partition) every time I boot my desktop, a Dell Dimension E520.While doing a repair on system drives from the windows installation disk has been recommended in forums, I am not sure if this would apply to a data drive.I have included a copy of winlogon and the system log (abbreviated) for info.I would be grateful for any recommendations/advice on steps to repairing the problem.Application logEvent Type: InformationEvent Source: WinlogonEvent Category: NoneEvent ID:1001Date: 03/11/2010User: N/AComputer: Description:Checking file system on K:The type of the file system is NTFS.Volume label is data.The volume is dirty.Cleaning up 4 unused index entries from index $SII of file 0x9.Cleaning up 4 unused index entries from index $SDH of file 0x9.Cleaning up 4 unused security descriptors.System LogEvent Type: ErrorEvent Source: NtfsEvent Category: Disk Event ID:55Date: 04/11/2010Time: 11:04:36User: N/AComputer: Description:The file system structure on the disk is corrupt and unusable.

sometimes when the check disk fails to initialize via explorer or fails to finalize at boot time, then the ultimate method to run check disk is via the recovery console. you simply have to boot up with any xp installation cd and select repair on the setup screen.the repair will then launch the "recovery console" and take you to the disk prompt where you can run help for a list of commands and switches.my suggestion is to run a chkdsk and a fixboot at the disk prompt. afterwards type "exit" and remove cd and reboot.incidentally if you get a subsequent error regarding the boot record then run the "fixmbr' command. when ever i need to use the recovery console i always run the three commands.something to keep in mind is that if the master file table on the k drive fails to reindex the files after the check disk then the ntfs may be on the verge of crashing. the only solution is to then reformat the drive.perhaps, it would be a good idea to take an additional precaution by copying the files on that drive over to another drive or upload them to microsofts "skydrive" website while you still have access to them.this is because any files that were added to the drive after the mft crashed will be lost after the chkdsk repairs the mft and if the ntfs crashes altogether you will loose everything on that drive.lastly, you might consider running a check disk on all your drives at least once a month. the command will ensure that your master file table is tuned up / reconciled to the file system.hthdb`...> DatabaseBen, Retired Professional - Systems Analyst - Database Developer - Accountancy - Veteran of the Armed Forces - @Hotmail.com "share the nirvana mann" - dbZen ~~~~~~~~~~~~~~~ > >

You need to run chkdsk /r on the afflicted volume and let it fix the file system corruption and it will clear the dirty bit if is succeeds.It is best to let chkdsk /r clear the dirty it for you.If you do not have a genuine bootable XP installation CD to boot the Recovery Console, make a bootable XP Recovery Console CD.Another advantage to running chkdsk /r from the Recovery Console is you can see what chkdsk /r has to say instead of waiting for it to finish (or not finish) on a reboot and looking in the Event Log for the report - it will be right there on the screen so you can see what it is doing.Use the XP Recovery Console to verify the file system on your HDD and correct any problems and then try to boot your system - this may be all you need to do. Or, you are welcome to just start trying things that might work.Boot into the Windows Recovery Console using a bootable XP installation CD.If you have no bootable XP media (or are not sure what you have) create a bootable XP Recovery Console CD and be sure.This is not the same as any recovery disks that might have come a store bought system. You can make a bootable Recovery Console CD by downloading an ISO file and burning it to a CD.The bootable ISO image file you need to download is called:xp_rec_con.iso Download the ISO file from here:http://www.mediafire.com/?ueyyzfymmigUse a new CD and this free and easy program to burn your ISO file and create your bootable CD:http://www.imgburn.com/Here are some instructions for ImgBurn:http://forum.imgburn.com/index.php?showtopic=61It would be a good idea to test your bootable CD on a computer that is working.You may need to adjust the computer BIOS settings to use the CD ROM drive as the first boot device instead of the hard disk. These adjustments are made before Windows tries to load. If you miss it, you will have to reboot the system again.When you boot on the CD, follow the prompts:Press any key to boot from CD...The Windows Setup... will proceed.Press 'R' to enter the Recovery Console.Select the installation you want to access (usually 1: C:\WINDOWS)You may be asked to enter the Administrator password (usually empty).You should be in the C:\WINDOWS folder. This is the same as the C:\WINDOWS folder you see in explorer.The Recovery Console allows basic file commands like: copy, rename, replace, delete, cd, chkdsk, fixboot, fixmbr, etc.For a list of Recovery Console commands, enter help at the prompt.First verify the integrity of your file system using the chkdsk command.From the command prompt window run the chkdsk command on the drive where Windows is installed to try to repair any problems on the afflicted drive.Running chkdsk is fine even if it doesn't find any problems. It will not hurt anything to run it.Assuming your boot drive is C, run the following command:chkdsk C: /rLet chkdsk finish and correct any problems it might find. It may take a long time for chkdsk to complete or it may appear to be 'stuck'. Be patient. If the HDD light is still flashing, chkdsk is doing something. Keep an eye on the percentage amount to be sure it is still making progress. It may even appear to go backwards sometimes.You should run chkdsk /r again until it finds no errors to correct.Remove the CD and type 'exit' to leave the RC and restart the computer.Do, or do not. There is no try.I need YOUR votes and points for helpful replies and Propose as Answers. I am saving up for a pony!

Thanks very much for your thoughts,I did attempt to run the CHKDSK from the recovery consul but it stopped after a few seconds showing the error message “Volume appears to have one or more unrecoverable problems”.Just tonight I ran CHKDSK /R on the drive with no reports of a problem, as soon as the CHKDSK /R finished printing to the screen CHKDSK started again on the file check (1 to 3) and reported no problems found. I then rebooted, CHKDSK ran again, and when I looked at winlogon it showed that there were two separate problems with the indexes and one security descriptor problem.
