What OS? In Linux, it's controlled via mt: 'mt compression 1' turns it on, and 'mt compression 0' turns it off. On other OSes, it can often be controlled via device names, i.e. /dev/rmt/0cn (compressions) vs. /dev/rmt/0n. You can also do this in Linux via stinit. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
