Attempting to get the most data onto my tape drives and my dumps seem to fill up the tape drive way to quickly. The tape capacity should be 8GB but I'm lucky if I get 500MB..... The dump commands I'm using are: dump -0un -f /dev/nrst0 / dump -0un -f /dev/nrst0 /tmp dump -0un -f /dev/nrst0 /var dump -0un -f /dev/nrst0 /usr dump -0un -f /dev/rst0 /u dmesg shows: (ahc0:1:0): "SONY SDT-7000 0195" type 1 removable SCSI 2 st0(ahc0:1:0): Sequential-Access density code 0x13, 512-byte blocks, write-enabled Supposedly I can select these other modes but dump fails with all: 125 [root] # mt stat Present Mode: Density = X3B5/88-185A Blocksize variable ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = X3.136-1986 Blocksize = 512 bytes Mode 2: Density = X3.39-1986 Blocksize variable Mode 3: Density = X3.54-1986 Blocksize variable Thanks, Chris Czerwinski
