Having some hard drive problems and I need to run a CHKDSK with the correction option.  However, when I run in SAFEMODE I get the error "CHKDSK cannot run because the volume is in use by another process".   How can I kill this process in command mode?

chkdsk C: /r

The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process.  Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)

Press the the letter y and then press the Enter Key.
Restart the computer for chkdsk.exe to run
> How can I kill this process in command mode?
You can't... the 'process' is Windows itself. That's why you have to reboot for it to run (and as pointed out by rrjmin0, needs to be run from an Administrator Command Prompt in Win7).

To open an Administrator Command Prompt, click the 'start' orb, type in cmd, hold down a Ctrl key and a Shift key, hit Enter (then release all 3 keys), and finally, answer Yes to the User Account Control prompt.

Dear User

If you run this on a different drive it will run, but if you try to run this on your system drive, It wont run and this can happen only your reboot and machine start.

best connect the drive to another PC, and run chkdsk then.
may i ask why you want to run it?
i only run chkdsk -  when i am sure the drive = OK; by running the disk diag first (quick test)

CHKDSK requires full access to all sectors on the drive and thus it asks for restart where it will run before Windows loads.
