I scandisk every week, generally from the Recovery Console. What I dont like about XP is that there are 3 scandisk routines :
The AUTOCHK/CHKDSK routine at startup (which doesnt seem to fix anything), the CHKDSK on a command-line in windows (which always reports errors, especially in $Bitmap. At least it reports what errors it found), and CHKDSK in the Recovery Console (doesn't say what it finds, but seems the most reliable - always seems to find something though, although I'm not sure its checks as much as that from the command line)
Which are you supposed to trust as all accept different parameters and return different results ?
Yes, I really am THAT good...
