Thread: Back online
I'm finally up and running (sort of) after upgrading my formerly
revlocked Linux system at home.
Tatsuo, I've got one last problem I was hoping someone could help me
with:
I've got a Fujitsu MO640 SCSI disk drive. At the moment, the system is
very unhappy with it; when I write to it the system ends up trying to
write to sectors way off the end of the drive, which throws SCSI errors.
In looking at Altavista, most of the matches on a reference to this
drive are in Japanese :( Any hints from the web would be appreciated.
I'm running Linux 2.2.14 from the Mandrake 7.0.2 distribution. My old
RedHat 5.2 system required kernel patches (which I had gotten from a
site in Japan), but ran with the drive without problems. btw, the
fundamental problem is with the 2048byte sector size on the disk.
Thanks.
- Tom

I have found Fujitsu's hard disk drives page written in English. http://www.fujitsu.co.jp/hypertext/hdd/drive/disk_e.html I could not find exactly the same drive you are using on that page, however. -- Tatsuo Ishii

Ah, that is because the MO640 is a magneto-optical drive, which is usually listed in a different area of the company. When I did an Altavista search on "MO640" many of the references were in Japanese (and a few in German), and I was hoping that there would be some mention of how to use the drive with Linux 2.2.x kernels. If you have a chance to look, that would be great. TIA - Thomas

Oh I didn't know that. I am going to look for Fujitsu's English MO disk pages... > When I did an Altavista search on "MO640" many of the references were in > Japanese (and a few in German), and I was hoping that there would be > some mention of how to use the drive with Linux 2.2.x kernels.

It's no different from every other removable disk. There's nothing special that needs to be done for this device -- that's why you don't find anything. ;-) -- Matthias Urlichs | noris network GmbH | smurf@noris.de | ICQ: 20193661 The quote was selected randomly.

Hmm. That is what I'm hearing, so I'm not sure why my Adaptec/MO640 is
blowing chunks when I try reading or writing.
Will keep poking at it :(

This is why its important to store drives without disks in them. To clean the optics you'll have to open the drive up and somehow gain access to them. On the larger 5.25" mechanisms this can be fairly easy (In the case of the Sony SMO-X501 drives), to fairly annoying (Any HP mechanism.) I've got a 3.5" Olympus mechanism that I need to clean and I suspect it may be on the difficult side. The 3.5" Fujitsu mechanism looks a little easier to get access to. Use a q-tip and alcohol. If you can actually find cleaning media then use that. -- | Matthew N.
