SubjectFtape bug
I have a problem with ftape. What happened was that I had a backup on
QIC80 tape that I made from Red Hat 5.2 and I (foolishly?) installed
SuSE 7.0. I then found I could not read the tape with the newer version
of ftape.

In the Ftape-HOWTO Claus Heine gives a check list of the things I
need to tell you about:

Kernel version: was 2.0.36, now 2.2.16

ftape version: 3.04d

model: Colorado Jumbo DJ-10/DJ-20

bus type: The motherboard has both ISA and PCI slots but I don't
think this is relevant because I wrote and read the tape
with the older kernel so it is not a matter of ftape not working.

what I did: I copied tob to the SuSE system and ran it. I didn't recompile
afio but used the SuSE version. All afio does is call ftape.

what went wrong: tob reported 'No input'. The log in /var/spool/messages
had a report from ftape to say that it was looking at a
new cartridge. An extract from the log is below. It was not
a new cartridge -- I have been able to read it by reloading
kernel 2.0.36 and the corresponding version 2.08 of ftape.

Current kernel: I still have it, and the file ftape.o

Another point: in Red Hat /dev/ftape is a link to /dev/rft0 while in SuSE
it is a link to /dev/qft0; Does that make any difference?

Before I try increasing the tracing level maybe you could let me know
whether this is a new thing or something you know about already.
