If you know the capacity, you already have enough to make a "close enough" guess at a tapetype: define tapetype HP_Ultrium_1 { # Based on manufacture spec of capacity. filemark 0 speed 1 length 100 GB } The speed value is not used. And unless you have a bajillion dump images, the filemark value is not all that important on this large a capacity device. Unless you are just the terminally curious type :-), save yourself the time that running (am)tapetype will take. FYI, amtapetype is just a renamed version of tapetype -- same program, same options, although at some point, [-b blocksize] was added. >I used the device > /dev/nrmt0 >so I think this should be without hardware compression (Linux). I don't think so. Based on what I know of Linux (which is minimal), I'm pretty sure you need to use the "mt" command to disable compression. Something like "mt -f /dev/nrmt0 compression off". Some OS's (e.g. Solaris) use the device name to control density and compression. Linux does not (I don't think). >Martin Öhler John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]
