How can to mount 720kB formatted FD?
I thought in a blink of an eye to simple backup some files at a floppy disk. It seems more challencing I ever expected. I've some floppies around and use these. I started with formatting it for 1.4 MB, with the following result: dar:~ # fdformat /dev/fd0u1440 Double-sided, 80 tracks, 18 sec/track. Total capacity 1440 kB. Formatting ... done Verifying ... Read: : Input/output error Problem reading cylinder 0, expected 18432, read -1 Alright an old floppy use a lower density: dar:~ # fdformat /dev/fd0u720 Double-sided, 80 tracks, 9 sec/track. Total capacity 720 kB. Formatting ... done Verifying ... done Seems to work fine. Now mount it: dar:~ # mount /dev/fd0 /mnt mount: you must specify the filesystem type Nothing has been mounted at /mnt before, so that's not the problem. It seems something needs to be done with a tool called: setfdprm. This tool uses the config file /etc/fdprm. The latter contains the following info about 720 FD: # size sec/t hds trk stre gap rate spec1 fmt_gap 360/360 720 9 2 40 0 0x2A 0x02 0xDF 0x50 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 800/720 1600 10 2 80 0 0x2A 0x02 0xDF 0x2E It looks like info is missing about 80 track 720kB formatted floppy disks. So I executed: setfdprm -p /dev/fd0 720 9 2 80 0 0x2A 0x02 0xDF 0x50 Though with the same result: dar:/etc # mount /dev/fd0 /mnt mount: you must specify the filesystem type Q: how can a 720 kB formatted FD be mounted (I can mount 1.4MB formatted FDs)?

fdformat does only low-level format, so what you need to do is create a filesystem on it with mkfs.* (mkfs.msdos, mkfs.ext2 etc.) You might also want to consider using KDE's floppy formatter KFloppy which allows you to specify filesystem, density etc. --Jyry C:-( C:-/ C========8-O C8-/ C:-(
Jyry, thanks for your information. This helps a lot. Backup is now in progress :) Op zondag 30 december 2001 13:08, schreef Jyry Kuukkanen:

I am receiving same sort of error on "bad" floppys. (I rather think my floppy drive at work is a bit bad, since there are so many...)

yes that's a way to *low level format* a floppy
Seems to work fine. Now mount it: dar:~ # mount /dev/fd0 /mnt mount: you must specify the filesystem type
yes. but you failed to that yet. ;-) It's low level formatted. try "mkfs -tmsdos /dev/fd0u720" (if memory suits right... try the man page of mkfs if it fails)
