Hi Guys,

I've got a 3 different tape drives I'm testing here, an internal LTO-2, external quantum LTO-3 and a sony external AIT-5 drives.

I've got 2 LSI and 1 adapter PCI-e SCSI controllers

It doesn't matter what cable, terminator or controller I use, the drives are always detected as narrow 40MB instead of 80/160/320MB 16bit. I've tried a lot and so far no difference. The scsi controllers ave very little configuration.

Any suggestions?

Alex

Crappy cables and cables that are too long will do it.   How long is the cable?

I absolutely agree with dlethe.

I've also seen some cases where a device on the SCSI bus doesn't ack as fast as it's supposed to, and so the controller ends up defaulting to a lower than possible speed for everything.   Is there anything else on the SCSI chain when you're doing your testing?

Also ... silly question, but this is an 80-pin cable, right?  Not a 50 or 68-pin?

Hye guys,

it is a 2 or 3 metre long external scsi 68 pin cable from the big to the small connector. The thing is, I tried another drive using the internal scsi connector with a cable that was like 50 cm long and got the same problem. No other scsi devices in this chain and properly terminated.

Odd :/

The 68 pin cable is the problem

IS was not the cable, it was also not the drive or the controller. It was the computer I was using for it.

I moved everything to a different server, cabled just exactly the same and all dives are now detected as wide and 320MB
