[Bug-cpio] MT command failure

[Andrew Grillet]

HI

I am using a Dell DDS72 drive with DDS72 cart, Ubuntu 12.04 on i386.

> mt -f /dev/st0 retension
This fails if cart is read-only, works with write-permit.

This is HIGHLY UNDESIRABLE.

It is very useful to be able to retension a tape that contains
valuable data prior
to reading that data, to reduce risk of read errors. Placing the cart
in a writiable state
risks the valuable data (especially if you have more than one drive online).
