After trying to mirror my harddisk with Norton Ghost, the damned tool
mirrored the wrong way.
Now the last 12GB of my 27GB hpfs partition are all 0xFF. Don't ask
me
why!

A check with dfsee tells me that there are thousands of errors
"allocation set, but not in FS-administration" or "in FS
administration, but allocation not set".

Should I run CHKDSK /F or are there better ways to recover?
