SYMPTOMS
A Windows Server 2003-based computer does not identify a Dell PV122T VS80 medium changer device. The device stops working after this problem occurs. The PV-122T VS80 appears as Benchmark VS640 DLT Autoloader in Device Manager. If you upgrade your firmware from V50 to V57 on the PV-122T VS80, you may experience this problem.



CAUSE
This issue is caused by a code problem in the Microsoft-provided Powerfil.sys driver. When a MoveMedium command is issued, Windows first determines if the transport, source, and destination element are out of range. A transport address is considered to be out of range if no transports are being reported. The driver does not identify the device if no transports are being reported.
