Several people asked for FAT check programs recently. Just for
checking, there is DSKMAP available from panarthea. An update to
deal with >16MB partitions has been posted today. This program does
no writing, so no repair. However, with some knowledge about FAT
and directory structure and just any sector monitor, you can repair
by hand, which is in my experience the safest to do.

There is DLII by Simon Poole, which checks and repairs disks,
and this has been posted by someone to panarthea, too. However, there
are minor bugs (one is an undeleted dataset will have its last sector
lost, another is a sector marked bad may be "recovered" as lost under
certain circumstances, and there may be more) in this program, and you
risk losing your data.  Also, I recall Simon told to the net that
DLII is not PD.

hope this helps,  Roland
