As you know, I've recently discovered TOSEC and
have been hoovering up the
media they've been archiving. At least on the Amiga side, the file formats are
completely open: one ZIP file per image, with the contents being a raw disk
dump in the case of floppies (aka "ADF"), and a CUE file plus the raw ISO-9660
filesystem and uncompressed WAV files for CD-ROM media.
is worth to remember that adf or dms only work with standart formats,
anything using none standart syncmarks, track lenghts, includes errors
cant be stored in those formats, they are only good for things where the
protection has been removed.
To make backup of your original software you would have to use either a
warper tool on the amiga, or hardware solution like discferret, kryoflux.
Warp was used in the bbs days to supple copies of the original software to
crackers, we would then work on removing the protection so it could be
copied with normal programmes.
Ofcause such a backup while it does hold all of the infomation of the
disk, one might not be able to write it back to a disk as a working copy,
certain protections needed to be writen back to the excact same place.
