Putting FDC into FM mode?
by Jules Richardson 07 Jan '06

07 Jan '06

(Note that this question is only relevant for well designed clones of the NEC and Intel chips - lots of broken clones don't support FM mode at all...) Is it possible from user-space to either: a) put the linux floppy driver permanently into FM recording mode for all subsequent requests, or b) do this temporarily for a per-command basis? I suspect that b) *might* be possible via a raw command, but the man page for fdrawcmd doesn't seem to mention being able to change the density bit (bit 6 of the first byte in the command). Anyone know (without me pulling source apart) whether fdutils supports it - and even whether the linux floppy driver supports it? (For all I know it may do something 'broken' like hard-coding the top three flag bits in the first byte of each command, and ignoring whatever gets sent from user space :) cheers Jules _______________________________________________ fdutils mailing list fdutils(a)tux.org http://www.tux.org/mailman/listinfo/fdutils

superformat doesn't work for me
by Mike Pepe 01 Dec '05

Hi all, Hope someone can point me in the right direction. I've been banging at this thing for months off-and-on and I can't get it to work. System is running Fedora Core 4, kernel is 2.6.14-1.1644_FC4smp. This is with fdutils 5.5 I'm trying to format old 8 bit OS9 disks in my 1.44 meg /dev/fd0 drive. The format is 720k, 80 tracks, 18 sectors, 256 bytes per sector, 2 sides. I'm using 720k media. I can set the parameters fine: [root@testbox bin]# setfdprm /dev/fd0 DS DD sect=18 cyl=80 ssize=256 but superformat has never worked for me, no matter what I do I get output like this: [root@testbox bin]# ./superformat /dev/fd0 Measuring drive 0's raw capacity Fatal error while measuring raw capacity 0: 40 1: 01 2: 00 3: 00 4: 00 5: 01 6: 08 if I use regular old fdformat, it works, but it reports the wrong number of sectors- so maybe it really doesn't work. Note that I can format the disks in the actual system and transfer images back and forth just fine. I just can't format them in linux. thanks -Mike _______________________________________________ fdutils mailing list fdutils(a)tux.org http://www.tux.org/mailman/listinfo/fdutils
