#SCSI Tape Problem
4 messages in this thread
Further to my previous posts regarding the Tandberg TDC 3600 tape drive I
am having problems with below is some additional information which may be
useful.
Old info:
Amiga 1200
GVP A1230 Turbo +II
GVP A1291 SCSI I/F
Tandberg TDC 3600 External Tape drive
AmiBack 1.05b Backup software
Problem:
When the software tries to write to the drive you get an "Illegal SCSI
request" error. It can rewind the tape, retension the tape, but not
read/write to the tape.
Before trying to rewind/retension you get the following error too "Mode
select failed, tape drive may not perform optimally"
New info (report from SCSIUtil d/l from AmigaUser):

tape)Removable medium: yes

Any ideas what else to try?

You mentioned having gotten output from SCSIutil. I have been trying to
solve a similar problem with my Wangtek tape drive and have not been able
to get SCSIutil to work. I can't figure out where to get the data used to
build the "scsi_id" needed in the command line. Would you please be so
kind as to help me?

Charlie,
the help provided with SCSIutil is not very clear, it took me a
while to figure out how to use it, but heres the low-down;
1. Find out what SCSI device driver you're using.
I'm using a GVP board, they imaginatively called their driver
gvpscsi.device, it will PROBABLY be in DEVS: From the shell type dir
devs: to get a list of the directory and look for something with SCSI in
it.
2. Make a note of the SCSI ID of your Wangtek tape drive.
This will be a number between 0 and 7, usually on the back of the drive.
If you can't find it, don't panic.
3. the format of the command is as follows;
scsiutil -dgvpscsi.device 002 -i
This would look at the device driver gvpscsi.device for a device on SCSI
ID of 2 (if you can't find your SCSI ID on the Wangtek, just go through
from 0 to 7 one at a time) and would report detailed information from the
drive. It's important not to have a space between the -d and the driver.
What problem are you experiencing with the Wangtek?

Thanks, it worked as advertised.
The Wangtek was slow as heck and some times the SCSI bus hung up. The fix
was to arrange the SCSI bus priorities so that the fastest devices started
at address 0 and the tape had address 6. I also had to low-level format
and repartition one drive which I suspect was causing the Bus hang-ups. I
still get that message about "mode failure drive may not operate
correctly" (or what ever) but it doesn't seem to hurt anything. I can now
do saves and restores at about 5mb per min.
Thanks again.
