Ooops. I must have been very nervous about getting my tape read back
that I made so many typos.

I finally solved it. The tape was written a bit weird at then.

dd if=/dev/rsa0 ibs=256k | tar zxvf -

solved the problem.

 I'm trying to read a DAT tape with important backup data.
 The device is a DEC TLZ04.
 sa0 at ncr0 bus 0 target 4 lun 0
 sa0: DEC TLZ04 1989(C)DEC 1915 Removable Sequential Access SCSI-2 device
 sa0: 3.300MB/s transfers
 
 When trying to read it (tar tvf /dev/rsa0) I'm getting a kernel message:
 
 (sa0:ncr0:0:4:0): 132497-byte tape record bigger than suplied buffer
 
 Any ideas? 

The tape has probably been written by a non-FreeBSD machine. Like an SGI or
something like that. They can do much larger blocksizes. I think FreeBSD is
limited to 64k (??).
