Is that version just in Lucid, or is it in Karmic too? Yes, I did try it with Mark's latest version (9.29b) which uses a sector count of "1" (version 9.29) and, in addition, uses ATA_12 (instead of ATA_16) for IDENTIFY (9.29b). The issue exists in Karmic and Lucid. It seems the report I sent back to Mark, once I tested 9.29b, didn't go to all of you but just Mark. Here it is: -------------------------------------------------------- The good news: It doesn't crash the chip anymore. The drive is still mounted fine after executing hdparm. The bad news: From the hdparm output it seems like the chip still doesn't play nice. /dev/sdb: outgoing cdb: a1 08 2e 00 01 00 00 00 40 ec 00 00 00 00 00 00 data: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 SG_IO: ATA_12 status=0x0, host_status=0x0, driver_status=0x0 SG_IO: bad response (not CHECK_CONDITION) Trying legacy HDIO_DRIVE_CMD outgoing cdb: a1 08 2e 00 01 00 00 00 40 a1 00 00 00 00 00 00 data: 40 00 ff 3f 37 c8 10 00 00 00 00 00 3f 00 00 00 SG_IO: ATA_12 status=0x2, host_status=0x0, driver_status=0x8 SG_IO: sb[]: 72 0b 00 00 00 00 00 0e 09 0c 00 04 00 01 00 00 00 00 00 00 40 51 00 00 00 00 00 00 00 00 00 00 SG_IO: desc[]: 09 0c 00 04 00 01 00 00 00 00 00 00 ATA_12 statQ err nsect lbal lbam lbah dev@ I/O error, ata_op=0xa1 ata_status=0x51 ata_error=0x04 HDIO_DRIVE_CMD(identify) failed: Input/output error readonly = 0 (off) readahead = 256 (on) geometry = 121601/255/63, sectors = 1953525168, start = 0 -------------------------------------------------------- I didn't get a reply from Mark on this yet.
