Networker Admins,

Is there ANY way to get data from a networker tape that has been
re-labled (but not used)?  Networker Version 6.1.1 .  The tape is
actually a clone tape.  Any help or suggestions would be appreciated.

Nothing in Networker.  The act of relabeling will cause a write to
occur
at the beginning of the tape.  For virtually every supported tape
device
today, that makes all data past that point to be inaccessible.

Some in the past have reported trying to overwrite the EOT mark by
writing some more data, then powering off the drive  before it can
write
another EOT.  I've tried it once on a DLT7K and didn't have any luck.

Recovery services have specialized hardware and software to read such
tapes anyway, but they tend to be expensive.  If the data on the tape
is
also expensive, it can be worth it.

Some drives will also permit you to fast forward beyond the EOT mark
and then begin reading again, at which point scanner could recover what
is left.  That is the trick, really: get beyond the EOT mark on the
tape somehow, then scan the rest of the tape with scanner.
