 using " tar -cvf /dev/rst0 filename"     
    to create ....
 trying " tar -tvf /dev/rmt/ntape1" 
    to list contents on Novell UnixWare 1.1.4

    gives me the following error...

    WARNING: TapeDrive: HA 0 TC 6 LU 0 -CHECK CONDITION
    logical block address = 0x00000014

    WARNING: Tape Driver: Block lenth mismatch
    Driver requested 10240, Tape block length = 0
    UX:tar:ERROR: tape read error: I/O ERROR

    I have made tapes on UnixWare and Linux boxes and been able
    to read the fine on FreeBSD box but not other way around 
 
    could the be so and still be byte swap trouble ???
