I just wonder how do I make back up to the HP Colorado T4000s tape drive? When I type mt -f /dev/rst0 fsf 1 , FreeBsd reply : st0(ahc0:2:0) Illegal Request asc:20,0 Invalid command operation code st0(ahc0:2:0) Blank Check req 52:1(decimal) asc:0,5 End of data detected I can't dump any files to the tape drive nor restore. I just wonder what the problem is? And how do I erase previous backup when the tape is full? For the incremental backup, how does it work? I am sorry that I am really new to the backup system, sorry for all this stupid questions. :) I will really appreciate for any help. Thanks in advance. rgd, Derek
