  I recently removed my hard disk without parking the heads and destroyed
a large part (maybe 10%) of my disk.  By repeatedly running Norton's Disktest
on it and deleting the bad files, I was able to get it to the point that 
Norton thought that no files were corrupted, but apparently the FAT said that
certain bad clusters were in use by files when in fact Norton said they were
not.  Norton advised me that this was not a harmful situation, but I would
not be able to use these clusters ever again.
  In spite of this assurance from Norton that my disk was OK, I kept getting
the message "General Disk Failure: Drive C", so I decided to reformat the disk.
This caused a number of interesting occurances.  For one, certain clusters that
were bad before were no longer bad upon running disktest.  Second, I still
got the same "General Disk Failure: Drive C" message, along with "seek error"
messages.
  Do you have any advice ?
