SCSI Magneto-Optical Drive Supported?

Post by Duncan C THOMS » Thu, 24 Mar 1994 01:06:44



We're looking to get an SCSI MO drive (probably about 1GB) on our
system.  Before I order it / install it, does anybody know if these
are supported by the Linux kernel, by patches, or would I have to
write a devide driver for it.  I know SCSI card drivers exist, but
which (if any) of the SCSI-CDROM, SCSI-tape and SCSI-generic drivers
work for MO drives.

I'd like to know before I install it on the Linux NFS server, or the
other PC which occasionally runs DOS...

Great job Linus, by the way!

I've got a 128Mo Magneto-optical drive on my linux box.

It works on my 1542B exactly as a hard-disk. I can mount this disk as any
hard-disk, it means I can put DOS, ext2, .... I only have to mount it
correctly.

A good feature is I can't eject the disk before I umount the drive. So, there
is not problem about changing disks.

In fact, it works great.

Which manufacturer ? Name of the drive ?

 ^^^^^^^^^

Is there anything special about how to mount it ? Please let us know.

I mean with good file system (msdos for dos, ext2 for extended-2, ....).

Nothing special.

1. Does LINUX support Magneto-Optical (MO) drives ?

Does LINUX support Magneto-Optical (MO) drives ? I am looking at the
Fugitsu 3.5 inch drive that supports 128M on each drive. I have
read a little bit on the technology and the drive and it looks good. As
you all know MO optical drives are READ/WRITE drives  where the READ/WRITE
access is much slower then a normal magnetic drive but you can you use the
media like normal floppy drives. Although its expensive then DAT Tapes but
the media life is much longer. Any way, the drives provide a standard SCSI
(or SCSI-II) interface.

I have the following questions:

a) Since the drives have standard SCSI interface and will be connected
   to my standard scsi card, do I even need any additional driver support ?

b) How will the MO-floppy change detection will take place ? Is it gonna be
   similar to the way floppy driver detects floppy drive change ?

c) Last but not least, has anyone dared to use these drives on Linux yet ?

Sincerely,

Sohail
