## SYMPTOMS

While you are attempting to run Backup from Windows NT with an Archive 4000, 2000, or 1300 4mm DAT tape backup connected to an UltraStor Ultra 24f SCSI controller, the application may freeze and the following error message may occur:
Hardware not responding

## CAUSE

UltraStor has confirmed that this behavior is caused by a problem with ROM versions prior to 008 on the Ultra 24f. Verify that the ROM version on the Ultra 24f card is at least 008. Any ROM revision prior to 008 will not work. The latest revision is 008.

## RESOLUTION

To eliminate the error message and back up properly, upgrade the ROM on the Ultra 24f to version 008.
For additional information, call UltraStor Technical Support at (510) 623-8955.
The Ultra 24f SCSI controller and the Archive tape backup products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
