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.

The products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
