After the last failure with ide-scsi emulation enabled, I tried again with the ide-cd driver: ------------------------------ cdrwtool -------------------------------- slacker:/home/rsmith/tmp/src/udf-cvs/udf/tools# ./cdrwtool -d /dev/hdc -q using device /dev/hdc 768KB internal buffer setting write speed to 12x Settings for /dev/hdc: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/hdc. The disc is going to be blanked and f ormatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now. Initiating quick disc blank Disc capacity is 275008 blocks (550016KB/537MB) Formatting track Writing UDF structures to disc 7200 (CEST)/-120 wait_cmd: Input/output error Command failed: 2a 00 00 00 00 00 00 00 20 00 00 00 - sense 09.00.00 Error writing packet 0 (ffffffff) ------------------------------ cdrwtool -------------------------------- Nevertheless I inserted the pktcdvd module, and tried to mount the disk, just to see what happened. The accompanying errors from syslog are: --------------------------- /var/log/syslog ---------------------------- Apr 30 13:22:19 slacker kernel: hdc: irq timeout: status=0xd0 { Busy } Apr 30 13:22:19 slacker kernel: hdc: DMA disabled Apr 30 13:22:21 slacker kernel: hdc: ATAPI reset complete Apr 30 13:26:45 slacker kernel: hdc: irq timeout: status=0xd0 { Busy } Apr 30 13:26:47 slacker kernel: hdc: ATAPI reset complete Apr 30 13:29:58 slacker kernel: pktcdvd: inserted media is CD-RW Apr 30 13:29:58 slacker kernel: pktcdvd: Fixed packets, 32 blocks, Mode-2 disc Apr 30 13:29:58 slacker kernel: hdc: packet command error: status=0x51 { DriveRe ady SeekComplete Error } Apr 30 13:29:58 slacker kernel: hdc: packet command error: error=0x50 Apr 30 13:29:58 slacker kernel: ATAPI device hdc: Apr 30 13:29:58 slacker kernel: Error: Illegal request -- (Sense key=0x05) Apr 30 13:29:58 slacker kernel: Invalid field in command packet -- (asc=0x24, ascq=0x00) Apr 30 13:29:58 slacker kernel: The failed "Mode Sense 10" packet command was: Apr 30 13:29:58 slacker kernel: "5a 00 08 00 00 00 00 00 0c 00 00 00 " Apr 30 13:29:58 slacker kernel: pktcdvd: 550016kB available on disc Apr 30 13:30:07 slacker kernel: UDF-fs: No partition found (1) --------------------------- /var/log/syslog ---------------------------- Hope this helps.
