During the 'attempted format'



I've tried a few different floppies, the result is the same. The system is 64-bit only, no 32-bit emulation is enabled using a strict 64-bit-only userland. Has anyone else gotten their floppy drive to work under 64-bit?

Is this just a case of a DOA floppy drive or is something else wrong?

Maybe booting from a 32 bit live CD would help determine that. It certainly was seen at boot time. Didn't get hooked to some SCSI device name by udev, did it?

Retried with some other floppies and later tried the original, everything seems to be working now, must have been a bad floppy/some transient issue.

Great! I did test that FC8 with a Fedora kernel will see and use the floppy. Even found a floppy to use. Now I have to figure out why I have a floppy with a gzipped ext2 filesystem on it. :-( Doesn't appear to be bootable, I thought it might be SYSLINUX for an old system which couldn't boot from CD or USB, but that doesn't seem to be the case.

Anyway, glad the problem went away.
