I need to correct something in an earlier posting of mine:

Someone's question:

My reply:

Well I had my bytes swapped and my bits inverted.  It was MS-DOS's chkdsk /f
that scrambled the disk and Norton Utilities that was used to repair it.  My
apologies to Norton and friends.


Just this morning another co-worker scrambled his MS-DOS 3.3 file system, on
an RLL drive, with chkdsk /f.  I used Norton Utilities to repair it.  So the
problem seems to be chkdsk vs. RLL.
