I'm running Linux Mint (an ubuntu derivative) and I want to mount ULTRIX
CDROM discs to see what I can see.
(I'm eventually going to image these, but I presume that will "just
work" with dd or ddrescue).
They are supposed to be UFS format (according to the net) and that
usually means you have to tell mount exactly which option to use (as not
all UFS implementations are compatible).
I've tried (all the options I can find) and failed:
$ sudo mount -t ufs -o ufstype=44bsd /dev/sr1 /tmp/mount
mount: /tmp/mount: wrong fs type, bad option, bad superblock on
/dev/sr1, missing codepage or helper program, or other error.
The CDROM would appear to be readable 9and I've tried a few anyway):
$ sudo file -s /dev/sr1
/dev/sr1: Unix Fast File system [v1] (little-endian), last mounted on
/UPS_MOUNT_TAR_SOURCE, last written at Wed Sep 28 16:27:45 1994, clean
flag 30, number of blocks 243648, number of data blocks 233295, number
of cylinder groups 38, block size 8192, fragment size 1024, minimum
percentage of free blocks 10, rotational delay 0ms, disk rotational
speed 60rps, TIME optimization
A later Digital Unix CDROM behaves the same way with mount and reports
this with file:
$ sudo file -s /dev/sr1
/dev/sr1: Unix Fast File system [v1] (little-endian), last mounted on
/kits/tmp/gendisk17665/mnt, last written at Wed Nov 20 13:38:02 1996,
clean flag 3, number of blocks 151168, number of data blocks 150383,
number of cylinder groups 24, block size 8192, fragment size 1024,
minimum percentage of free blocks 0, rotational delay 0ms, disk
rotational speed 60rps, SPACE optimization
I also have a few OSF/1 CDROMs, which I assume are also the same format.
Any ideas? I can't be the first person to try to do this ...
