In the 7 years since I started the ImageDisk project,
I think that Erics
request to expand the format to support mixed-sector-sized disks
which I received a couple of weeks ago was the first request I've
had about mixed sector sizes disks - and his was only for the
format specification.
In addition to that XDF and HP format, which in my limited experience with
it, seems to be able to do OK WITHOUT the extraneous sector, I can think
of one other mixed sector size: Ensoniq Mirage
ALthough I would strongly urge you not to give it excessive priority, . . .
I can see some [rare] need for handling them for emergency data
recovery.
The guy with the Ensoniq was able to "FORMAT" a disk by "cloning" a
disk
using an Option Board, and then reading and writing sectors with INT13h
(plus 1Eh, of course, for the non 512 byte ones)
