Defrag will not run until the scheduled chkdsk has run.
If you are getting one of these messages:
Cannot lock volume for direct access
or
Cannot open volume for direct access
Symantec AntiVirus Corporate Edition 9.0 can cause the problem.
Chkdsk.exe or ScanDisk fails to run on Windows XP or Windows 2003 after

A program called Hitman Pro can cause the problem.
A really old version of ZoneAlarm (a version from 2004) can cause the
problem.
BitDefender Internet Security 9 can cause the problem.
[[Ok BitDefender live support told me yesterday that they are working on it

Spyware Doctor can also cause the problem.
The /x switch doesn't work if Spyware Doctor is installed. Spyware Doctor
needs to be uninstalled or you can do this...
Quoted from *PCTools*, *Spyware* *Doctor*...
1. Exit from Spyware Doctor (to exit from Spyware
Doctor please right click on the Spyware Doctor icon in
the notification area (next to the clock on the Windows
taskbar) and select Exit from the menu that appears)
2. Delete the file
ikhlayer.sys from %windir%\system32\drivers\
or
from c:\windows\system32\drivers\
3. Restart Spyware Doctor
Chkdsk, defrag and error-checking should now work.

[[There is currently no fix for this problem.]]
[[NOTE: You may have success if you schedule Chkdsk to run at startup and
use the /X switch, which will force a dismount. ]]

JSI Tip 7079. You receive 'Cannot open volume for direct access' when Chkdsk
runs during Windows XP startup
http://www.jsifaq.com/subO/tip7000/rh7079.htm
To run chkdsk from a command prompt.
Start | Run | Type: cmd | Click OK |
In the command prompt, type:
chkdsk C: /x
Hit your Enter key.
The following error message appears:
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)
Type Y, hit Enter and close the command prompt.
Reboot.
The /x switch: Use with NTFS only. Forces the volume to dismount first, if
necessary. All open handles to the drive are invalidated. /x also includes
the functionality of /f. The /F switch fixes errors on the disk.
