There were no other processes. Even with a completely new/blank installation on a different Server, it was not possible to get it runnig. The drive was never recognized. Now I migrated from Hyper-V to 2008 R2 and every thing is fine. Without any trouble. Thanks.

Hello,
I've just installed Tape Redirector on Hyper-V Server 2008 R2. My HP LTO-4 tape drive is the only device connected to a Adaptec 29320lpe HBA. It is shown in Device Manager and can be accessed with HP Library and Tape Tools but Tape Redirector doesn't find it. Any suggestions?

Regards, Tobias
