Err Msg: Boot Device Inaccessible.... with Adaptec 1640 (108872)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
This article was previously published under Q108872 SYMPTOMS
When you are using Windows NT with an Adaptec 1640 SCSI controller, your
boot drive may corrupt if more than three SCSI devices are connected to the
SCSI bus and your boot drive is SCSI-controlled. An error message appears
when Windows NT is starting:
Boot device is inaccessible.
CAUSE
According to Adaptec technical support, this problem is caused by:
- Improper termination.
-or-
- A problem on the SCSI bus cable, such as bad hardware or hardware that
does not meet specifications, resulting in power leakage on the SCSI
bus.
RESOLUTION
If the problem is caused by improper termination, use an active terminator,
instead of passive termination.
If the problem is caused by a power leakage on the SCSI buse, you can put a
terminator on the SCSI card itself. If the problem is resolved by adding
the terminator, check the SCSI bus for proper termination and cabling
problems.
