Recently, when I 'chkdsk' my hard disk, I get the following error message:
	c:\> chkdsk
	Volume BIG_BLACK   created Jan 1, 1991 12:00a
	Probable non-DOS disk.
	Continue  (Y/N)?
If I type 'y', it continues and everything works fine.  The DOS manual claims
the FAT ID byte is bad and that the disk has become 'badly damaged'.  In fact,
the disk seems to be functioning perfectly well.

Is there any way I can fix this problem besides reformatting the disk?

Thank you,
Daniel Lewart
