First, he's been using /dev/rst0, thus rewriting the tape from the beginning anyway. The `weof' marks will be over- written if you rewrite the tape, so they are pointless. I think the key is that these el-cheapo drives really require the tape to be formatted, and the sudden abort caused the medium format to be corrupted. Alan, do you know whether that's true? (Also, watch out the console/syslog SCSI error messages.) If so, you might try to use scsiformat -wq /dev/rst0.ctl -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
