Can't Run Scan Disk

[Starchild]

all of a sudden I can no longer run scandisk to check for errors and bad sectors. I continuously get the message"File system is NTFS, can not open volume for direct acess-"
WHAT has happened? I used to be able to run scan disk after I restarted-now it will not run at all...HOW can I fix this?

First xp doesnt have a scandisk,its CHKDSK. If you have the xp cd install it,
exit the page,go to run,type:cmd In cmd type:CHKDSK /REVERT
Close out,restart computer,boot to xp cd,recovery,press enter for password,
at cmd screen type:CHKDSK C: /R
When thru type:EXIT

it, when it xp started i thought it was strange that scandisk didnt't run.
then when i checked out my pc the program had vanished, why?
