C5683A HP TapeDrive Diagnostics?

[bence8810]

Hello,

I inherited this server wiwh a HP C5683A SusperStore DDS4 drive. It seems to do an OK job with the backup (NTbackup), but when I start the Diagnostics tool, it wont load it in. When I start the Diagnostics, I get prompted for I/O mode. If I select ASPI, it wont find the drive at all, and if I select NT Miniport, it will find the drive, but it has a Red cross over it, and if I click it it says:

This device is not responding to commands from the host machine.

There are several potential causes:
- the device could be switched off,
- the device could be disconnected from the bus,
- the device could be a wide device co-located with narrow devices on the same bus (some scenarios).

But when I do the backups, it works fine. What might be wrong? Why cannot I run the Diagnostics on it?

Thanks

Benedek
