Hi, I've got a SATA 2.5 inch disk which is currently unreadable, though not password locked nor presenting any errors during a SMART selftest. I've tried to access it both using a SATA USB Bridge and a SATA cable and couldn't do it with neither of them. I've also tried to reset it using hdparm, blocking DMA and using PIO (libata.dma=0), blocking ncq (libata.force=noncq), and I still cannot find out what is happening with this device. The most meaningful error logs are: [ 126.156761] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 [ 126.156770] ata1.00: irq_stat 0x40000001 [ 126.156777] ata1.00: failed command: READ DMA [ 126.156788] ata1.00: cmd c8/00:08:08:00:00/00:00:00:00:00/e0 tag 17 dma 4096 in [ 126.156788] res 51/04:08:08:00:00/00:00:00:00:00/00 Emask 0x1 (device error) [ 126.156794] ata1.00: status: { DRDY ERR } [ 126.156798] ata1.00: error: { ABRT } [ 126.159279] ata1.00: configured for UDMA/133 [ 126.167330] sd 0:0:0:0: [sda] [ 126.167335] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 126.167339] sd 0:0:0:0: [sda] [ 126.167342] Sense Key : Aborted Command [current] [descriptor] You can read the full logs of dmesg, hdparm and smartctl at http://paste.ubuntu.com/11699099/ With udev running the log messages go berserk as it keeps trying to read the device without success. I'm running Debian kernel 3.16.7-ckt11-1 and hope someone here will be able to help me sort this out. Thanks
