Don't understand, my TK50 is not working.
Only tar cannot use it. Can i find other archiver utility?

With "dd", i can use it, but the: "tar -cvf /dev/mt0 file.ext" is not
working.
The "dd if=file.ext of=/dev/rmt0" is working.
The file is about ~10MByte, and symply "txt".
(i'm generated this file, for testing)
(compress with zip, the compressed size is about ~20% of original size)

Part of the /var/log/messages:

I don't undertand data error, because this tape is working correctly under
VMS.

If you want, i can send full file (now about ~29kByte).
