Raw ftape

[Robert Goto]

I dd out an IDT tape using rawft0.  DD'd it back in to a different tape.
1. Tape volume label was not transfered.  Under IDT it read zftape volume.
2.  Not all the data appears to have been dd'd out.

When I try to restore the new tape using IDT, IDT cannot get the file detail
information and dies.

Could this be because of the issue mentioned here about bad sectors and
segments?
