Hi all,

I just got a Dell PowerVault 100T DDS4 tapedrive and would like to
ensure that when bcking up with AMANDA (www.amanda.org) the
hardware compression is OFF.

Obviously I can turn it off on the drive itself (DIP-switch 1)
but that also be doable using a SCSI command.

Question is: How do I do that? Is there a special tape device
(/dev/nrmtu0 or such for *u*ncompressed access and the driver
will take card of that), or does AMANDA know how to send
SCSI commands to its device [ I could not find anything though
on first look].

I am running a 2.4.18 kernel.

Any help is appreciated.

thanks
