Hi all!

Have a problem with my SCSI-tape...
I have a Adaptec 2940 Ultra SCSI host adapter
Seagate ST34572W 4.2 SCSI HDD
& Exabyte SCSI tape int.
I rebuild my kernel :
....
options		SCSI_DELAY=15
.....
controller	ahc0
controller	scbus0

device		sd0
device		st0
.....
....

Then i install new kernel.
...... 
ahc0: <Adaptec 2940 Ultra SCSI host adapter> rev 0x01 int a irq 11 on pci0.15.0
ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs
ahc0: waiting for scsi devices to settle
scbus0 at ahc0 bus 0
sd0 at scbus0 target 0 lun 0
sd0: <SEAGATE ST34572W 0876> type 0 fixed SCSI 2
sd0: Direct-Access 4340MB (8888924 512 byte sectors)
ahc0:A:2: refuses WIDE negotiation.  Using 8bit transfers
st0 at scbus0 target 2 lun 0
st0: <EXABYTE EXB-850085QANXRC 05E0> type 1 removable SCSI 2
st0: Sequential-Access density code 0x0,  drive empty
......

Then I wanna make a dump & have a strange...

# /sbin/dump -0u -f /dev/rst0 /usr/home/ftp
  DUMP: Date of this level 0 dump: Wed Mar 11 22:16:56 1998
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /usr/home/ftp to /dev/rst0
  DUMP: bad sblock magic number
  DUMP: The ENTIRE dump is aborted.

What can I do ???
Please help me, if it possible.
