Hi, I'm the original reporter. The sense data is smartctl's interpretation of the ccb union. In particular, the bytes are from ccb->csio.sense_data and it calculates 18 from ccb->csio.sense_len - ccb->csio.sense_resid (32 - 14). I don't know if that is correct or not. FWIW, here is the output from CentOS 6.3 on the same machine: REPORT-IOCTL: Device=/dev/sdc Command=SMART STATUS CHECK Input: FR=0xda, SC=...., LL=...., LM=0x4f, LH=0xc2, DEV=...., CMD=0xb0 [ata pass-through(16): 85 06 2c 00 da 00 00 00 00 00 4f 00 c2 00 b0 00 ] scsi_status=0x2, host_status=0x0, driver_status=0x8 info=0x1 duration=17 milliseconds resid=0 >>> Sense buffer, len=22: 00 72 00 00 00 00 00 00 0e 09 0c 00 00 00 00 00 00 10 00 4f 00 c2 40 50 status=2: [desc] sense_key=0 asc=0 ascq=0 Values from ATA Return Descriptor are: 00 09 0c 00 00 00 00 00 00 00 4f 00 c2 40 50 [Duration: 0.016s] Output: ERR=0x00, SC=0x00, LL=0x00, LM=0x4f, LH=0xc2, DEV=0x40, STS=0x50 REPORT-IOCTL: Device=/dev/sdc Command=SMART STATUS CHECK returned 0 It appears to have the same ata pass-through command but completely different sense data. __Martin
