Hi,
I have several (different) MO drives -- including
a small jukebox.
But, it seems that most OS's don't have support
for them -- usually the BLOCKSIZE != 512 issue
is the killer.
Amusingly, *Windows* seems to talk to all of them
(but that is my last choice!). I believe Linux
will, as well (but I don't want to run Linux).
[I think I would prefer to get them running
under Solaris or NetBSD]
So, given that these devices have been around for
ages, what was talking to them?
Thanks,

don,
from your list above what "most" os's
dont support
the MO devices? I dont recall having any problem
with SCSI attached MO drives that I have used since
at least with PC platforms, they are mapped to being
bios supported units.
Maybe non PC platforms? I used them with Solaris
on sparcstations, and with HPUX, and AIX on their
respective platforms to interchnge data.
There was a jukebox support program distributed
that I used one time that would issue commands to
the jukebox devices, but most of the time I used
MO drives only.

I've just not had any luck getting machines
to recognize the 1024 or 2048 byte sector sizes.
*If* they talk to the drive, they end up treating
it AS IF the sectors were 512 bytes -- so you end
up only seeing 1/2 or 1/4 of the total disk capacity.
I've seen ADD ON products for MO support on things
like Slowaris... but, it doesn't seem to be native.
HPUX *may* be an exception (the JB is an HP product)
but I don't run HPUX... :-/
Or, am I just missing some little "trick"?? :-(

Sector size does mess up things. If you are not
using the device for booting, then it should not be
an issue.
I never saw anything but 512 byte / sector work
with any windows or dos version. the drivers dont
have any way to change the blocksize. I didnt
see the problem you saw when using 1024 byte
media, it just would spit it back out and do nothing.
Solaris should have no problem with this, and
of course booting wont be a problem there.
There is a jukebox program, I'll have to air out
the brain cells and try to remember what that
was called. If this rings any bells with others on
this list, chime in. The package I'm thinking about
is a public domain thing, i believe it works for
MO libaries, but is also written to issue select
commands to tape libraries. YMMV. it is
a good basis to start with.
It is not going to support different volumes
which auto select like the Pioneer cd 6 or
18 pack drives do, or the NEC scsi cdrom
drives do, which would be cute, but is only
framework to open a scsi target id, and issue
a select command to pull and swap in a different
media to a drive. I recall that someone had
used it with MO jukeboxes but I only saw it
used with DLT libraries. (Breece Hill).

New subject: IBM 1620 panel on Ebay
The photos of this panel are exceptional With the current mix of
bidders, this
one will probably set more bidding records. 370 panels are a dime a dozen
compared to 1620 panels. only one to hear from now is Dennis K about
2 second before the end of the auction.

Well, if I can't build a filesystem on it, then it's
sort of a moot point! :>

I am pretty sure the Windows machine had *no* problems.
The UN*X boxen all seem to gag on the != 512 byte
sector size...

of course booting wont be a problem there.
I am almost 100% certain Solaris did NOT like the
1024/2048 byte sectors. I will try to make time this
weekend to test each medium/drive on a variety of
machines just to be sure.

I can always use the front panel controls on the JB
to move media to/from the drives. I am more concerned
with trying to get full *use* of the media (i.e. not
throwing away half of each physical sector)

The Pinnacle Micro MO stuff offered two types of media; 512 byte and 1024
byte sectors. I've got an Apex 4.3GB 512-byte sector cart around here
someplace. The drives would die if you looked at them cross-eyed--and I
think the miserable field record of the Apex drives contributed to the
eventual bankruptcy of Pinnacle.
Youi can still find the drives on ePay. In my experience, if you find one
that looks like a good deal, the seller will not warrant that it works.

Rumor has it that Chuck Guzis may have mentioned these words:

I have a MaxOptix Tahiti1 drive here on the shelf - 5.25" FH, heavy sucker,
standard SCSI - it'll take Tahiti 1G disks (500M/side - the one disk I had
always had R/W errors & problems) and standard 600Meg disks (300Meg/side -
the 2 I had worked flawlessly) - 512byte sectors. The only difference I
could see w/the Tahiti disk was that the sectors were staggered & there
were more sectors on the outer cylinders of the disk. Who knows: maybe that
confused the drive.... ;-)
From what I understand, the 650Meg disks (325Meg/side) disks had 1024 byte
sectors, and would not work with my drive.
AFAIK, it still works tho I haven't used it in prolly 4-5 years or so...

So who made good MO drives back in the 1990's?
I have a Fujitsu 230MB 3.5" drive, a FWB Hammer 1300 that just came in today
(Maxoptix T3-1304 drive), and a Olympus MOS525. The last 2 drives are 5.25"
1.3GB and all are rewritable. Last year I lucked into the Olympus and
Fujitsu for free along with a huge box of media (quite a bit still in
shrink-wrap). I snagged the FWB box because I like having atleast 2
compatible drives around if I decide to archive material I will want to read
down the road. Atleast with my DDS4 tape drive I am sure I can find a
replacement cheap in 5 years, the old MO are still hard to come by cheaply.

AFAIK, most of the 650/MB1.3GB drives were okay, even the Pinnacle ones.
But Pinnacle got into a bunch of trouble pushing the technology to 4.3GB
and above.
What was the MO drive on the Next cube--650 MB? Seemed silly to me to
market the thing without a hard drive--and I think Next eventually came
around to that way of thinking.
