Hi everybody,
I have a problem with my WangDat 3200 DAT streamer and AHA 2940 under
S.u.S.E. Linux 5.2.

ID 0: IBM harddisk
ID 1: Toshiba CD-ROM
ID 3: external jaz drive
ID 4: WangDat streamer

With kernel 2.0.35 and pre7 patch included and no tape in the streamer
I get:

But I have only one jaz drive and if I disconnect my jaz, there are 2
CD-ROMS detected.

With kernel 2.0.32 and no tape inserted I get:

The streamer is detected!

Any hints?
If you need more info, please let me know.

BTW: Does anybody know what the following message means?

Aug 28 15:00:26 bobo kernel: st0: Error with sense data: Current error st09:00: sns = f0  4
Aug 28 15:00:26 bobo kernel: ASC=40 ASCQ= 0

Where may I search for such messages?

Thanks in advance
