The note says "no compression tar -xvf /dev/rmt/0". When I try to read it, the kernel says the record is too big? (ahc0:4:0): "WangDAT Model 3100 03.0" type 1 removable SCSI 2 st0(ahc0:4:0): Sequential-Access density code 0x13, 512-byte blocks, write-enabl ed The physical media is the same 90 meter tapes I use all the time without problems. ******************************** ROOT@interlock:/u3>mt -f /dev/rst0 status Present Mode: Density = X3B5/88-185A Blocksize variable ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = 0x00 Blocksize variable Mode 2: Density = 0x00 Blocksize variable Mode 3: Density = 0x00 Blocksize variable ROOT@interlock:/u3>tar -xv tar: read error on /dev/rst0 : Input/output error st0: 128874-byte record too big ******************************** Any hints? I can easily read/write other tapes. I get the same message if I dd, cat, tar, or otherwise try to read the tape. Thanks - Mark chapman@cs.uwm.edu
