List: I keep archival floppy disk copies of EPROM images on CDROM and occasionally need to DD them back to a floppy disk for my programmer to load. I recently upgraded two of my shop computers from FreeBSD 7 Stable to FreeBSD 9 Stable with clean installs. I tried the 'fdformat' command prior to 'dd' of the image file yesterday. All of my floppy disks showed errors on all tracks. I used a ^C to abort the command and the PC dropped core. I used the same disks on my laptop with OpenBSD 5 and everything worked as expected. I was able to format and diskdupe the image to them. I looked over the Release Notes for FreeBSD 9 and there wasn't any mention of eliminating floppy disk support on either FreeBSD 8 or 9. This happened on two different PC's, both running FreeBSD 9. The hardware isn't suspect because these same two PC's were able to format and dupe images when running FreeBSD 7.

Dd wrote the image ok, but when closing the device, the machine panicked. Problem is gone on 8.2 and 8.3 (prerelease), and I haven't tried 9 yet. -- Eivind
