Reading past EOT on Sun QIC tape drive

[Patrick Barron]

Can anyone tell me if it's possible to read past an end-of-tape mark on a
Sun QIC tape drive (i.e., an "st" tape drive)?  One of my users
accidentally blew away a tape he'd written by writing an empty file at the
beginning of the tape.  Just about all of his data is still there, but I
can't convince the st driver to let me read past the EOT marker.  It looks
to me like the driver is trying to be too smart for its own good - is
there a variable or something in the kernel I can patch to make the driver
a little stupider...?  :-)

Thanks!
