dd: unexpected short write, wrote 0 bytes, expected 512

[Dominal]

Hello!

When we write a 50M text file (bigfile.asc) to our DEC TKZ60 (3480) tape drive, the following error displayed:

dd: unexpected short write, wrote 0 bytes, expected 512

The command we used is:

dd if=bigfile.asc of=/dev/rmt/0cn bs=512

It seems the error is refer to end of tape but the capacity of the cartridge is 210M and the file size is just 50M.

Please advise.

Try using a larger block size. For some tape drives the minimum is 1024. Annihilannic.
