missing drive

[pepar]

I have two Seagate drives attached to the onboard SCSI in on an Asus P2B-DS. Only one shows in my OS - Windows XP Pro. Entering the host adapter's setup - both drives are listed. It knows they're both there, what they are and how big they are. However the boot up info only lists a size for one of the drives. The second drive has been verified and low level formatted via the SCSI utilities, but canot be seen via any of the disk management tools, not even good ole FDISK. Does anybody have any suggestions? Thanks in advance for the assistance!

Only thing I can think of is checking to make sure they have different SCSI IDs.

Thanks, they do.

Is this a dual channel SCSI adapter? If it is, Windows may not have detected the second channel.

Thanks everyone. It turned out to be a bad cable. From now on I check that FIRST.

It's annoying when statistical anomalies rear their ugly head, and you test for a bad cable with another bad cable. Kept me puzzled for quite a while.
