Hi,

shred -v /dev/st0    # where /dev/st0 is the drive in a multi tape carousel.

This starts well with.
Pass 1/4 (random) 15MiB
Pass 1/4 (random) 41MiB
Pass 1/4 (random) 70MiB
Pass 1/4 (random).....etc

But when the end of a 200GiB tape is reached in pass 1, 'shred' doesn't appear to trigger a rewind or maybe wait for the tape to be rewound before attempting to overwrite the data.


The final messages before and around the error are:-



Pass 1/4 (random) 190GiB/190GiB  100%

Pass 2/4 (random)

Error writing at offset 1288. No space left on device.

(The next line in my script then runs and unloads the tape.)

Is this not rewinding the tape a bug or my mis-use of the 'shred' command?

Thanks

Rupert Russell
