Please give examples of the tar commands that you have been using. One common problem with streaming tape drives is if you do not supply the data to the drive quickly enough then it has to stop, rewind the tape, find the correct location and resume writing again. This can sometimes be fixed by supplying a blocksize to tar so that it sends enough data to the drive to keep it busy and avoid this. Also, do you have hardware compression on or off?
