Computer Hangs, or SCSI Controller Cannot Always Find the
Drives

•

 

Check SCSI parity for consistency and be sure SCSI termination is set correctly.

•

 

Check cable length and integrity. Check pin-1 orientation.

•

 

If the SCSI controller LED remains on when the computer hangs, the host
adapter may be interfering with your computer's operation. It may be installed
in a motherboard slot that does not support First-Party DMA (i.e., Bus Master)
data transfers. See your computer documentation.
