Er... well, right, there are at least three different tape drive types
which have been sold as Sun 411 tape drives.

The Archive Viper is a QIC drive, so the driver should be correct.  The
Viper is known to be some sort of a beast with changing behaviour depending
of the firmware revision.  Anyway...

Not exactly.  You made an strace of tar, but I asked for an strace of
`mt -f /dev/st0 status'. 

There's also a SEGV in your strace which you didn't mention before.  Is
that reproducible?

What I'd like to see is this.  Please download the latest snapshot DLL
http://cygwin.com/snapshots/cygwin1-20050819.dll.bz2 and install it
instead of your current Cygwin DLL.  Rename your current Cygwin DLL before,
so you can move it back to its orignal name when you're done.

Send the output of cygcheck as described on http://cygwin.com/problems.html,
send the bzip2'ed strace of `mt -f /dev/st0 status` and send the file
tar.exe.stackdump after you have reproduced the SEGV with the snapshot DLL.
