SUMMARY
The Hardware Compatibility List for Windows NT states that the
following Hewlett-Packard (HP) SCSI tape drives are not supported on
the Adaptec AHA-1742A SCSI Host Adapter:
Hewlett-Packard 35470a
Hewlett-Packard C1503a
Hewlett-Packard C2224c
This information is correct; however, the entire Adaptec AHA-174x
series is based on the same chip set. Therefore, these Hewlett-Packard
SCSI tape drives will not function properly on any adapters in this
series, such as the AHA-1740.
You may be able to get these Hewlett-Packard SCSI tape devices to work
properly on the Adaptec AHA-174x series SCSI host adapters by placing
the Adaptec card in standard mode, which forces the host adapter into
an AHA-154x emulation mode. This is done through jumpers on the card.
NOTE: Before you change the 174x SCSI card to emulate a 154x, you must
also change the Windows NT SCSI driver using Windows NT Setup in the
Main group. Using Setup, Add the Adaptec 154x driver and Remove the
174x driver.
This information has been confirmed by Hewlett-Packard technical
support. For additional information, contact Hewlett-Packard technical
support at (208) 323-2551.
