I am having trouble getting my computer to see this drive combination
If you're expecting anyone to try to help you, you'll need to provide
more information.

What OS are you using? What is the configuration of your SCSI chain?
Does the SCSI controller recognize the drive (make sure the SCSI BIOS
isn't set to control it)?

Athelon 2.6 GHz, XP home, the Tekram 315U. I have a 3 plug scsi cable.
One to card, one empty and the end plugged into an active terminator,
plugged into Jaz. I have also tried putting drive on the middle and the
terminator on the end. It sees the drive but locks up if I try to read
the contents. I have a portable scsi 2 gb Jaz which works off the
external port.. That works fine except I either have a lot of bad 2 gb
disks or it wont read or format them.

I'm not sure how to check the scsi bios for the Tekram. The web page
specs says it has no on board bios. I had an Adaptec in my machine but
when I did CTL-A at boot it says the card is not installed right. I put
it in my wife's 1.3 GHz and the card goes into bios ok. I may have to
transplant the internal there in case there is some issue with the
computer I have.

That might be a drive and/or disk problem.

What happens when you insert a disk into the drive? You should hear
it engaging the heads and spinning up the disk, and the access light
should come on for a moment before going off again. If it doesn't
happen that way, then there is probably something wrong with the drive
or disk. You might try it with the SCSI cable disconnected to rule
out problems elsewhere in the SCSI chain.

Are there any disks that work OK in this drive? If so, do the same
disks not work in the internal drive?

BTW, make sure you use Iomega's software if you format any Jaz disks.

As far as I can tell using Google, it doesn't have a BIOS, so it looks
like that's not a matter for concern.

That message about the card not being installed right does seem odd.
Do you have proper Win XP drivers for these cards? Have you tried
installing them in different slots on the motherboard (you might have
a resource conflict, and changing slots sometimes helps solve that).

It might be a good idea for troubleshooting to try the internal drive
in your wife's computer. If it works there, then you'll know the
drive is OK and the problem lies elsewhere.

The drive spins up, I get formatting errors on the internal. I put it a
1.3 GHz with the adaptec and it does the same thing. I format disks in
the external ok.

I'm pretty sure the internal is broken. There is an issue with some of
the four 2 gb disks not running properly in the external. Just might
have bad drives. Unfortunately no one locally has any. Our local
computer store has never sold any Jaz disks just Zip's which I have and
work fine.

Time to go to eBay

Thanks for ideas

It might be time to give it up on Jaz since it's been discontinued for
so long. Buying a used drive from EBay could be nothing but a risk and a
pain if it doesn't work. If you really need random read/write capacity
on removeable media in the 2Gig+ range per disk you might want to look
at magneto optical drives instead. They're still in production. And
you'll save a ton of money on the media. In the US you can take a look a
Fujitsu drives at http:\\www.fcpa.com to get an idea of features, costs,
specs etc.

My experience with excessive Fujitsu drive failure in my Answering
Service business machines has made me swear off anything by that name.

The prime use is archiving and dual layer DVD seems affordable except
nobody seems to have media on the market yet.

Their hard drives or the optical drives? Just curious. I have had MO
drives fail after about 4 years or more of *heavy* daily use. (They tend
to run hot when writing and I've since installed extra cooling fans for
the drives.) Even so, the thing I like about them is that if a drive
fails is simply stops writing. It doesn't kill the contents of the disk
in the process, which Zip and Jaz drives have great potential to do when
they fail. I gave up on Zip after Iomega replaced both drives and disks
a total of *six* times. Their final thoughts on the matter were "Since
we can't tell which disk(s) keeps taking out the drive you will have to
send them all back for replacement."

Thing that scares me about DVD is the higher data density, dual
layering, and subsequent potential to easily damage the disks. A scratch
on a CD might be one thing to recover from. But a scratch on a dual
layer DVD? Just a thought. IIRC MO disk "shelf life" for data storage is
rated at over 30 years. And in the industry that's considered to be a
very conservative estimate.

Ahh the overheated Fujitsu. The drives we had failed from, it appeared,
the head position control chip, very discolored. . I have one on the
shelf that we 'borrowed' the board to determine if the drive contents
were there. It worked so we stripped the drive and sent the loaner
back. Curious thing. I had a 20 gb Fujitsu die and I tried the
'defective' control board from the 40 gb (same board number) and the 20
came back up ok, but it won't run the 40 gb, Gotta love technology...
THE remaining 40 gb drive has a drive cooler, the type that mount
underneath and blow on the board. Our machines run 24-7 being a small
call center. Now my Netware server has six Conner and IBM scsi's and
blow a lot of hot air and has only had one intermittent drive in 4 years
its been up.

We record all our phone calls and that adds up to a lot of space and now
that we have to log two taxi companies and an order line it will get
worse. The DVD is mainly to archive those calls. One CDROM will not
quite take one phone's calls for a month. It will be written, verified
and then into the safe. I somehow have the feeling the dual layer will
be used to copy the new HiDef DVDs that I hear are coming. It's a moot
point since it seems there seems to be no media available for it yet. I
figure spending the $100 US for the new drive and then waiting out the
market to get a reliable media while I use a regular DVD for archiving.
Even a regular DVD is a quantum leap from a CDROM. Personally I'd love
to have a pair of huge mirrored drives and leave all the calls on the
server for at least a year

Our corporate accounting and correspondence wont even fill a zip drive.
Our Call Center program is dos based and after 12 years is still under
50 Megs of files, not bad since that includes two towing companies doing
6000 calls per year.

Did you have right termination in your scsi chain?

Just a question...
