One of my old 37GB Seagate Cheetah SCSI drives died last week in my system. It was one of two drives in my system.

I finally got a replacement...two replacements, actually...identical Fujitsu MBA3147NP 147GB U320 SCSI drives...one to replace the dead Cheetah, and a second as a dedicated back-up drive.

When I plug either drive into the system, the system boots normally, the LSI Logic SCSI Adapter scans for the drives, and everything starts perfectly. When I add the third drive into the system, it gives a "device not found" error during initialization, and neither drive is seen. What could I be doing wrong? I can't think of what to do next.

BTW, the LSI Logic controller's software is set to disable RAID functionality (it was orignally set as enabled). That didn't change anything. It still doesn't work.

Help!
