No ScanDisk - that's Windows 9x

CHKDSK
 
Checks a disk and displays a status report.
 
 
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/C] [/L[:size]]
 
 
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
filename FAT/FAT32 only: Specifies the files to check for fragmentation.
/F Fixes errors on the disk.
/V On FAT/FAT32: Displays the full path and name of every file
on the disk.
On NTFS: Displays cleanup messages if any.
/R Locates bad sectors and recovers readable information
(implies /F).
/L:size NTFS only: Changes the log file size to the specified number
of kilobytes. If size is not specified, displays current
size.
/X Forces the volume to dismount first if necessary.
All opened handles to the volume would then be invalid
(implies /F).
/I NTFS only: Performs a less vigorous check of index entries.
/C NTFS only: Skips checking of cycles within the folder
structure.
 
The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.




Then after a CHKDSK I'd run the DEFRAG of the drive as I've seen many times that CHKDSK has found errors during the building process of a system. Depending on how severe the error is Defrag may or may not flag it so I don't recommend simply running DEFRAG without first running CHKDSK
