The bug I have observed is that when a file on the hard disk has the 
read-only bit set (i.e. is marked as read-only) and backing it up causes
it to span over more than one disk, the restore is corrupt.  I don't
know if the problem occurs in backup or restore.  (Does it matter from
a practical viewpoint?)  The only way I have found to live with this is
to simply not use the read-only bit.  This is inconvenient for me because
untrained people use my PC but what else can I do?  I discovered the bug
when part of my database was lost.  I managed to fix it, but not thanks
to DOS.
