Windows 2000 does not have the "Scandisk Utility", instead it has a utility called Error Checking
They basically do the exact same thing.
To start the error checker...
Double Click on My Computer
Right click on the drive you want to check
Click on Properties
Click on the "Tools Tab
Click on "Check Now..."
Make sure there is a check by,
"Automatically fix file system errors",
and "Scan for and attempt recovery of bad sectors"
Click Start
Error Checker will finish
Click OK
Click OK
