Whenever I attempt to initialize a floppy disk, either from the
Workspace or from the command level, it fails. Here is an example:
localhost# disk -i /dev/rfd0a
Formatting disk /dev/rfd0a:
blocksize = 0x200
density = 720 KBytes
gap3 length = 84(d)
........................................................
...read : rawio.status = 8(d)
Sony MPX-111N 1440: unknown disk name
In the /usr/adm/messages log, I find:

This happens with every disk I try. Any suggestions? I would suspect
bad disks, but I got similar results on ten different disks, and they
were 'name brand' disks: TDK, BASF, and Toshiba (the new 2.88 that
came with my station :-( )

I went out today and bought some 3M disks, and they worked like a charm. BTW I have *never* had a bad disk from 3M, which is something I cannot say about any other major diskette brand. I think the NeXT could be more robust in this area. My old PC could format a disk with bad sectors; it just didn't use them. Seems that the NeXT must have a perfect floppy or it'll puke it back out. -Allan
