Stupid SCSI

[NascarFool]

Recently I picked up an LSI U160 SCSI card, a 68pin two device cable and a pair of 18.2GB 10k Cheetahs. I had to order two 80pin to 68 pin adapters too. The drives were DOA, they would not format but yet the SCSI card did find them. Fortunately the trader that I bought them from refunded me after I sent them back. Well, yesterday I got two refurbished drives from an on-line store. Last night I tried to get them going without any luck. The drives are not detected by the SCSI card. Both drives spin up and the activity lights are on until they get up to speed. I tried every SCSI ID possible on both drives without any luck. I tried one drive with a terminator installed on the end connector of the cable. Still nothing. I tried running DiscWizard from Seagate but it says I have no SCSI controller. I can enter the SCSI setup program on the LSI U160 card, so that tells me that the card is working. Any suggestions ? ?

The new drives.... are they also SCA 80pin? If so, check those adapters for jumpers. They may be set to narrow only, or something like that.

As far as the card goes. I would move it to a different PCI slot. SCSI and ATA RAID dont get along, and SCSI sometimes is picky about onboard ATA as well.

Look at each drive. Make sure the terminate power jumper is installed on both drives. Only terminate the last device on the chain. When you tried the single drive with a terminator, was it an active terminator? Was it a pass through terminator (had a connection on each side)? If it was, that means it is meant to be on the back of the drive. They dont like to be hanging in the breeze, as that is an open connection.

Lastly make sure the terminator is turned on in the SCSI card BIOS. Also set the High/Low termination to auto.

Good Luck

The SCSI card has auto termination. I actually got both drives up and running. Don't know how I did it but I did.
