I'm having a slight problem with an HP C1533A DAT.
The thing gets probed ok:
st1 at scsibus0 targ 5 lun 0: <HP, C1533A, 9406> SCSI2 1/sequential removable
st1: density code 0x13, variable blocks, write-protected

but when I try to read from it , I get this error:
st1(aha0:5:0): timed out
st1(aha0:5:0): command aborted, data = 00 00 00 00 4e 00 00 00 00 00 00 00 00 08
st1(aha0:5:0):  DELAYED ERROR, key = 0x3
st1(aha0:5:0): medium error, data = 00 00 00 00 11 00 00 00 00 c3 00 00 00 08

Any ideas ??
