SYMPTOMS
The Windows NT SCSI port and class drivers do not currently support any SCSI device types above 7Fh. This may cause problems with current and future SCSI devices that have device types greater than 7Fh.



STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem was corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
