Hi:

I'm having a problem with my new (well new to me) SCSI tape. My tape drive
is as follows:

(from dmesg:)

(bt0:5:0): "WANGTEK 5150ES SCSI ES41 B170" type 1 removable SCSI 1
st0(bt0:5:0): Sequential-Access density code 0x5, 512-byte blocks,
write-enable

or if empty:

(bt0:5:0): "WANGTEK 5150ES SCSI ES41 B170" type 1 removable SCSI 1
st0(bt0:5:0): Sequential-Access density code 0x10,  drive empty            

and when I try to write to the drive I observe:

# mt status
Present Mode:   Density = X3.136-1986  Blocksize = 512 bytes
---------available modes---------
Mode 0:         Density = 0x00         Blocksize variable
Mode 1:         Density = X3.136-1986  Blocksize = 512 bytes
Mode 2:         Density = X3.39-1986   Blocksize variable
Mode 3:         Density = X3.54-1986   Blocksize variable
# dd if=/kernel of=/dev/rst0
dd: /dev/rst0: Invalid argument
1+0 records in
0+0 records out
0 bytes transferred in 0.016702 secs (0 bytes/sec)
# tar cvf /dev/rst0 /usr/sbin
tar: Removing leading / from absolute path names in the archive.
usr/sbin/
usr/sbin/uuchk
tar: can't write to /dev/rst0 : Invalid argument
#
   

and this is generated on the console:

st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0
   

But mt erase seems to work. At least the tape runs for quite awhile.

My question: why is this happening? Could it be a media problem? The tapes
were previously used with a lower density Wangtek (and Archive) drive on a
Sun 3/60. 

I have tried using mt density to reset the density to different values, but
this makes no difference.

Any assistance appreciated. I've already searched the FAQ, Handbook, and
mailing list archives.

Kevin
