I have a QIC-24 cartridge tape that had a number of files on it, and
then had another file written to the tape at the beginning. This overwrote
at least one of the files on the tape, of course, but should not have harmed
the remaining files after that point.
How can I recover the remaining files on the tape? I tried using mt
and dd to move past EOT and continue reading, but had no luck. Is there
some magic sequence of tape ioctl's I can use to skip the first file on
the tape and then continue reading subsequent files?
I am using a QIC-24 SCSI tape drive on a Sun 3/280 running SunOS 4.0.3.
