Knows anyone this problem with DLT8000 and TSM 4.1.3.0 under NT?

To label a tape works fine.
When TSM try to write data on the tape a undefined write error occurs
without any sense keys .
With the DLT7000 drives we have no problems.

Environment:

NT 4.0 SP5
TSM 4.1.3.0

Drive firmware:

STK DLT8000:        V43 and V51
Quantum DLT8000:    V20
