My scsi tape drive used to work ok with the original 386bsd scsi driver.
However after installing Julian's new scsi driver the tape is found ok:

 aha0 reading board settings, scsidev=7 150 nSEC ok, use 200 nSEC 
   **aha0 probing for scsi devices**
   dev0,lu0: type 0(direct),fixed 'NEC     D5882           G01 ' scsi1
 	sd0: 621MB, cyls 1633, heads 15, secs 52, bytes/sec 512
   dev4,lu0: type 1(sequential),removable 'ARCHIVE VIPER 150  21247-005' scsi1
 	st0: scsi tape drive, 0 blocks of 512 bytes
   dev6,lu0: type 5(readonly),removable 'MATSHITACD-ROM CR-5XX   1.0b' scsi1

The disk and CD-Rom work ok but when I try to write anything to a tape with
'tar cvf /dev/rst0 .' these errors are reported:

 st0: medium error block no. 40 (decimal)
 st0: medium error block no. 21 (decimal)
 could not write_filemarks st0
 st0: medium error block no. 40 (decimal)
 st0: medium error block no. 21 (decimal)
 could not write_filemarks st0

I can read tapes ok and retrieve a file but nothing will write.
I have tried several different used and new DC6150 and DC6250 tapes but
still the same error.
I'm sure it must be something simple but I just cannot figure it out.
Anyone any ideas?
Thanks.
