Hi,
To Mary and Bill and others who may be interested, we recently had a
discussion on providing termination power of the SCSI bus. I just wanted to
pass along this information I found on Adaptec's site.

Description:
When two or more SCSI hard drives are attached to the SCSI controller, SCSI
Select intermittently sees the hard drives but FDISK returns 'No Fixed Disk
Present' when executed.

How can I resolve this?

This information applies to the following product(s):

- 1505 series, 1510 series, 1515, 1520 / 1522 series, 1530, 1540 / 1542
series - ISA SCSI Card(s)
- 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series,
3940 series, 2940U2W series, 2930U2 series, 3950U2 series - PCI SCSI Card(s)

This information applies to the following Operating System(s):

- All / PC

Solution:
Most hard drives have an option for Termination Power (often labeled as "TP"
or "TermPWR"). If the hard drives that you're using have jumper settings for
Termination Power, then verify the jumpers are set to:

"Disabled" or "Receive Termination Power from SCSI bus"

Adaptec's ISA and PCI SCSI controller cards provide termination power to the
SCSI bus. If one or more devices also set to provide Termination Power to
the SCSI bus, then the devices may not be detected normally by FDISK.
