In those days, I used SuperZap and other programs on my old TRS-80 (models I
through 4). When I switched to MS-DOS in the mid-80's, I discovered the
Norton Utilities, especially DiskEdit, which let me explore and change bits
and bytes on my floppies and humongous <g> 10 MB hard disks. Even learned
to fix those weird FAT(12) tables, with their leap-frog cluster numbers.
In the 90's though, Symantec bought Norton and their utilities became more
fluff and eye-candy and less actually useful. I still have the 1999 version
of DiskEdit.exe, which lets me do a few things on the few FAT volumes that I
still have. I can even read some NTFS with it, but I don't know the meaning
of what I see.
I don't know whether the current Symantec products still include DE, or
whether the current version is worth having. If you can find the '99
version, though, and can boot to MS-DOS and run it, you might be able to
look at the actual bytes in your problem directory - and fix them.
Good luck. Please let us know, because somebody else is sure to come along
with a similar problem and we'd like to be able to help them.
