HP DLT VS80 says EOT immediately?

[Palle Girgensohn]

Hi!

Just bought a new DLT device, and it won't play with me:

dmesg:

sa1: <HP DLT VS80 5E40> Removable Sequential Access SCSI-2 device
sa1: 10.000MB/s transfers (10.000MHz, offset 15)

If finds end of tape immediately? How come? This is on FreeBSD 4.10. Is it 
possible that the tape device is not supported? Is there a patch for this?
