Hi I am running Core 2 with a SCSI Controller INITIO INIC 1060P and HP DDS-4 C5683A DAT drive. I really want to try and get my backup routines sorted for Christmas but I am struggling with some errors when creating TAR archives. the result from mt -f /dev/st0 status is SCSI 2 tape drive: File number=-1, block number=-1, partition=0. Tape block size 0 bytes. Density code 0x0 (default). Soft error count since last status=0 General status bits on (50000): DR_OPEN IM_REP_EN I am getting a lot of the following error messages. tar: /dev/st0: Cannot read: Input/output error tar: Skipping to next header tar: Archive contains obsolescent base-64 headers tar: /dev/st0: Cannot read: Input/output error On previous attempts (before I manually set the block size), I was seeing a lot of these st0: error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7). inia100:13 0 Can anyone give me some pointers that might help solve this? Thanks, Jon
