System: DEC UNIX 4.0D
Is it possible to format on UFS file system on a floppy disk?
I am trying to do the following:
disklabel -w -t ufs /dev/rfd0c rx23
Looking at /etc/disktab the rx23 entry defines a 1.44 MB floppy disk.
So far so good, everything works and disklabel -r /dev/rfd0c informs:
...
a: 2880 0 unused 0 0 # (Cyl. 0 - 79)
b: 0 0 unused 0 0 # (Cyl. 0 - -1)
c: 2880 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 79)
...
Then I try to do:
newfs -m 0 /dev/rfd0c
newfs: /dev/fd0c: no default sector size
zsh: 12150 exit 8 newfs -m 0 /dev/fd0c
??? What's the problem? That should work just fine, the disklabel
does inform 512 bytes/sector so why can't the mkfs_ufs read it from there?
The floppies work just fine, if an MS-DOS filesystem is used (with
mtools utilities).
