I wondered if I were mixing the two OSs, myself. I didn't think so, but
Looking at this:
[blinky@thurston blinky]$ less /etc/fdprm
# /etc/fdprm - floppy disk parameter table
# Common disk formats. Names are of the form
# actual media capacity/maximum drive capacity
# (Note: although 5.25" HD drives can format disks at 1.44M, they're listed
# as 1200 because that's the common maximum size.)
# size sec/t hds trk stre gap rate spec1 fmt_gap
360/360 720 9 2 40 0 0x2A 0x02 0xDF 0x50
1200/1200 2400 15 2 80 0 0x1B 0x00 0xDF 0x54
360/720 720 9 2 40 1 0x2A 0x02 0xDF 0x50
720/720 1440 9 2 80 0 0x2A 0x02 0xDF 0x50
720/1440 1440 9 2 80 0 0x2A 0x02 0xDF 0x50
360/1200 720 9 2 40 1 0x23 0x01 0xDF 0x50
720/1200 1440 9 2 80 0 0x23 0x01 0xDF 0x50
1440/1440 2880 18 2 80 0 0x1B 0x00 0xCF 0x6C
I don't see the 1.8-ish-MB size that we're talking about, but maybe *if*
this is what I used it was with a prior installation of Linux, so my
tracks aren't still in the mud.
Also, there's setfdprm (man setfdprm), but that doesn't address any
specific formats.
Also², there's this:
http://www.handhelds.org/download/di...2/etc/mediaprm
Look at that first list.
