But as a
file-format geek, I always thought a central part of the
nut to crack was a metafile format. Archiving real-world antique
floppies means some of them are going to have bad sectors. (Let's
leave copy-protection errors aside for a moment.) You need an
archiving file format that can record the fact of the known error.
It would also be handy to have a way to store corresponding info
such as a description of the disk's contents, as if you'd be
able to store the label along with the archived disk image.
This already exists since more than 10 years now and is called TeleDisk,
As far as I know the format of a Teledisk archive file has never been
officially documented. IMHO that makes it totally unsuitable to use as a
portable archibe format. And I don't think it covers things like GCR
recording, sectors with headers recorded at a different density to the
data, hard sectored disks, and so on.
also try AnaDisk to analyse foreign disks, both
programs can be found
everywhere on the net.
Only if you happen to run an MS-DOS PC.
