SCSI Experts HELP!Can'tconnect Quantum Atlas 10k to 29160N

[hawk_sys911]

Hi... I have a problem... First I had a 2940U2W adaptec to which was attached a SCSI

Quantum 10K Atlas. As this Quantum HDD has a unique HD68pin connector, I have bought thru

ebay an adapter 50/68pin to HD68. And with standard cable plugged to the 68pin

fast/ultra-SE connector of the board everything worked. But As I wish to migrate to Vista,

I changed controller and found a 29160N. Now all the peripherals (CD/DVD) attached to the

50pin connector work perfectly, but I can't connect the ATLAS HDD. As I plug it in the

LVD/SE connector (29160 has not a 68pin FASTULTRA/SE) the controller hangs. I doesnt even

try to scan the devices. It hangs and after some minutes returns a "time out" message. I

tried everything, even to force the SE mode on the HDD (even if it's labeled LVD/SE and

should work with that connector!) I tried to shorts the jumpers SE-TE and/or LVD/SE on the

29160N board but I had NO results. Of course the chain is terminated because the cable

itself has a termination. I don't know what to do... any suggestions???

Thanks for any help you may give....

... 29160N ...

If not tried already and presuming that HDD is configured correctly,
You can see if BIOS update assists.

Have you tried the adapter with only the HDD connected to it? Can you get into the 29160 BIOS?

[hawk_sys911]

Yes! Bios is the latest, and HDD is configured ok. If course I also tried to make it work alone. But NO difference... So I don't think it's a problem regarding the two channels working together...

I think the trouble must be in some kind of configuration that doesn't work in the LVD connector, instead of the old 2940u2w fast-ultra 68pin connector... besides I know it's a strange thind as the Atlas hdd is an LVD disk, so I had to experiment troubles on the 2940U2W instead!

Thanks again, any further help is appreciated....

Best...

Do you have the HDD set up as ID0?

[hawk_sys911]

No I didn't. I can try... but why just ID0????

[Dimarini]

ID0 will make sure the PC boots from it.

[hawk_sys911]

Oh, now I see... but I'd really wish the trouble was booting the PC!!!

When I attach the HDD, Adaptec 29160N can't even scan the devices...! It hangs! That's the problem! The boot troubleshooting is far, far away........!!!

[Dimarini]

I thought you said earlier you could get into the 29160's BIOS??? It generally scans all the devices before you enter the SCSI BIOS. If you cant get into the SCSI BIOS, try removing all of the devices from the SCSI bus and then accessing the SCSI BIOS. Then you can check the setup.

I just noticed from your first post, is your HDD LVD or SE?

Are you using one cable for the HDD, and a different cable for the CD-ROMs?

[hawk_sys911]

Hi, if you press CTRL+A you can access the BIOS BEFORE it scans the devices... then you can try to check all the setup, but when you reboot (or if you try to scan the bus from the bios itself, it hangs (a timeout error after one minute or two appears)

Yes, the HDD is LVD, but you can force SE mode if you like (of course I tried this option...)

[Dimarini]

Is there a terminator on your LVD cable?

[hawk_sys911]

Yes, there is. It's one of those twisted pair LVD cable with the termination at the end...

[Dimarini]

I think I am about out of ideas. Sorry I couldn't help you.

[hawk_sys911]

Don't worry... thanks for being trying... I appreciate a lot... Let's hope someone's got some new ideas...
