chkdsk /f doesn't work

I have windows 2000 professional installed on my PC. The configuration is 256 MB RAM, 40 GB Hard Disk and AMD processor.
When I open DOS prompt and write the following command

chkdsk /f

it asks me if I want to do the checking on startup and even thought i press y noting happens on startup (the disk is not checked and OS loads normally).

But if I go to  My Computer--> right clicked on drive icon and select properties ---->click on tools --->Press Check Now----> select both the checkboxes---->click start

it displays  the following error on startup.

Cannot open volume for Direct access.

I checked the event viewer and found the follwoing error.

The application chkdsk.exe generated an application error. Error occured on 12/01/2004@19:34:39:031. The exception generated was C0000005 at address 6E799399 (NUMBER_SET :: NUMBER_SET)

What could be the reason for this problem?

>>i'm not sure why this would happen, however, have you tried booting with the Windows 2000 Pro CD and using the recovery console to run the chkdsk command

Can u please tell me how to use the recovery console. I have tried to repair the OS though. But it didn't help.

i assume you figured it out, by giving me the points and whatnot to the answer... i seem to have missed my update on this question...

however, to answer your other question, to use the recovery console, you insert your Windows 2000 Pro CD, and reboot, when it prompts to boot from CD, do so... Windows 2000 install will load, then it will ask you to install a new version of 2000 or repair, choose repair, manual, by recovery console. it will ask you for the partition (probably providing the location of the one you'll probably need to fix anyways) and prompt for the administrator password... so make sure you have all that information handy.

do a chkdsk /? and theres an option that at the end says "implies" an another switch, i think the one is "/r" so then do that switch and target the drive in question. for example, if i'm indeed correct that the switch i'm referring to is /r, and you wish to check your C: drive, then the correct command would be "chkdsk C: /r"

do this several times to ensure the problem is fixed.
