I am having a little problem here. I have installed a Toshiba DVD-RAM device. I have placed a CD in the tray (write protect - off). I am trying to get this device to format and mount. Below is a list of the commands I used, below that are the results (screen writes) that I see, and below that are some snips from the tail of the dmesg log. Before I completed these steps, /stand/sysinstall would start up and then drop to the command line. After I completed the steps below, /stand/sysinstall would start (VERY long wait time), but did not see the ad0 Any ideas???? This is the dmesg information for the hard ware Version 4.2-RELEASE FreeBSD dmesg info: CPU: Pentium II/Pentium II Xeon/Celeron (299.33-MHz 686-class CPU) real memory = 134205440 (131060K bytes) avail memory = 126377984 (123416K bytes) da0 at ahc0 bus 0 target 6 lun 1 da0: <TOSHIBA SD-W1101 DVD-RAM 1030> Removable Optical SCSI-2 device da0: 6.756MB/s transfers (6.756MHz, offset 15) da0: 2380MB (1218960 2048 byte sectors: 255H 63S/T 75C) cd0 at ahc0 bus 0 target 6 lun 0 cd0: <TOSHIBA SD-W1101 DVD-RAM 1030> Removable CD-ROM SCSI-2 device cd0: 6.756MB/s transfers (6.756MHz, offset 15) cd0: Attempt to query device size failed: NOT READY, Medium not present ==== Below are the commands issued ========== dd if=/dev/zero of=/dev/rda0 count=2 bs=2k disklabel /dev/rda0 > label disklabel -R -r /dev/rda0 label newfs /dev/da0c ==== Below are the results of those commands ========== #dd if=/dev/zero of=/dev/rda0 count=2 bs=2k dd: /dev/rda0: Input/output error 2+0 records in 1+0 records out 2048 bytes transferred in 369.995157 secs (6 bytes/sec) t# disklabel /dev/rda0 > label disklabel: /dev/rda0: Input/output error # disklabel -R -r /dev/rda0 label disklabel: /dev/rda0: Input/output error # disklabel -R -r /dev/rda0 label disklabel: /dev/rda0: Input/output error # newfs /dev/da0c newfs: /dev/da0c: Input/output error heavylift# /stand/sysinstall ==== Below are some snips of dmesg ========== da0 at ahc0 bus 0 target 6 lun 1 da0: <TOSHIBA SD-W1101 DVD-RAM 1030> Removable Optical SCSI-2 device da0: 6.756MB/s transfers (6.756MHz, offset 15) da0: 2380MB (1218960 2048 byte sectors: 255H 63S/T 75C) cd0 at ahc0 bus 0 target 6 lun 0 cd0: <TOSHIBA SD-W1101 DVD-RAM 1030> Removable CD-ROM SCSI-2 device cd0: 6.756MB/s transfers (6.756MHz, offset 15) cd0: Attempt to query device size failed: NOT READY, Medium not present da0s1: slice starts beyond end of the disk: rejecting it da0s2: slice starts beyond end of the disk: rejecting it da0s4: slice starts beyond end of the disk: rejecting it (da0:ahc0:0:6:1): SCB 0x2 - timed out in Command phase, SEQADDR == 0x156 STACK == 0x180, 0x150, 0x0, 0x2e SXFRCTL0 == 0x88 SCB count = 10 QINFIFO entries: Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Pending list: 2 Kernel Free SCB list: 3 5 6 7 8 9 1 0 Untagged Q(6): 2 sg[0] - Addr 0x33d8000 : Length 2048 (da0:ahc0:0:6:1): BDR message in message buffer ============================================== Most jet drivers look down their noses at helicopter aviators.
