I have copytape working on a sun and Convex, but it fails on sgi.
mt -t /dev/rmt/xmt0d0.1600 rewind
copytape /dev/rmt/xmt0d0.1600 tape.tmp
gives:
copytape: can't read input: Invalid argument
Anybody have this gem (or equivalent) working on an sgi? Thanks, John

For those who don't know about copytape, from the manpage:
copytape duplicates magtapes. It is intended for duplication of
bootable or other non-file-structured (non-tar-structured)
magtapes on systems with only one tape drive.
copytape is blissfully ignorant of tape formats. It merely makes
a bit-for-bit copy of its input.
In normal use, copytape would be run twice. First, a boot tape is
copied to an intermediate disk file. The file is in a special format that
preserves the record boundaries and tape marks. On the second
run, copytape reads this file and generates a new tape.
% copytape /dev/rmt8 tape.tmp
% copytape tape.tmp /dev/rmt8
% rm tape.tmp

I never got any replies a few months ago about anyone having copytape running on IRIX. It would still be a great addition to our bag of tricks around here. Does anyone have it working? I only need it to work on a local 9 track tape drive. (it works fine on BSD systems, Sun and Convex around here). Thanks, John yates@c.chem.upenn.edu P.S. One place it can be gotten from is: apple.com in pub/ArchiveVol1/unix_util as copytape.tar.Z .
