Dear all,
How do I actually low-level format a floppy disk in an
USB-Floppy-Disk-Drive?
I tried as with usual drives, using fdformat:
[~]>fdformat /dev/sdd
Could not determine current format type: Invalid argument
But setting the format failed as well:
[~]>setfdprm -p /dev/sdd 1440/1440
ioctl: Invalid argument
Next up scsifmt:
[~]>./scsifmt /dev/sdd fmt
scsifmt: non-sense ioctl error
Didn't work too well, too. Any ideas?
Best regards,
Christian

Does not mkfs suffice?

No, he's talking about low-level format. This is necessary before writing
anything on a floppy for the first time or after defects have been detected
(remember these old ages ?).
Cheers,

Yeah but the scsi *disk* driver does not seem to handle *floppy*
requests (just as it does not handle *cdrom* ioctls). I sense a Missing
Feature here.

I'm just wondering whether an SCSI floppy drive should support the hard
disk command set (including low-level fmt). I'm not even sure that our
sd driver supports those commands itself ! Clearly smelling -ENOFEATURE...
