I am trying to optimize my new drive, and I attempted to set its UDMA mode last night:
# hdparm -X70 /dev/hdd /dev/hdd: setting xfermode to 70 (UltraDMA mode6) HDIO_DRIVE_CMD(setxfermode) failed: Input/output error The drive is ATA 133 and I believe UDMA mode6, consequently. Any ideas on this I/O error? Here's the rest of the info that the drive dumps: # hdparm -i /dev/hdd /dev/hdd: Model=Maxtor 6Y080L0, FwRev=YAR41BW0, SerialNo=Y2PXN2ZE Config={ Fixed } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=4047/16/255, CurSects=16511760, LBA=yes, LBAsects=160086528 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 *udma2 udma3 udma4 udma5 udma6 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: (null): * signifies the current active mode # hdparm -I /dev/hdd /dev/hdd: ATA device, with non-removable media Model Number: Maxtor 6Y080L0 Serial Number: Y2PXN2ZE Firmware Revision: YAR41BW0 Standards: Supported: 7 6 5 4 Likely used: 7 Configuration: Logical max current cylinders 16383 4047 heads 16 16 sectors/track 63 255 -- CHS current addressable sectors: 16511760 LBA user addressable sectors: 160086528 device size with M = 1024*1024: 78167 MBytes device size with M = 1000*1000: 81964 MBytes (81 GB) Capabilities: LBA, IORDY(can be disabled) Queue depth: 1 Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Advanced power management level: unknown setting (0x0000) Recommended acoustic management value: 192, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5 udma6 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Commands/features: Enabled Supported: * NOP cmd * READ BUFFER cmd * WRITE BUFFER cmd * Host Protected Area feature set * Look-ahead * Write cache * Power Management feature set Security Mode feature set * SMART feature set * FLUSH CACHE EXT command * Mandatory FLUSH CACHE command * Device Configuration Overlay feature set * Automatic Acoustic Management feature set SET MAX security extension Advanced Power Management feature set * DOWNLOAD MICROCODE cmd * SMART self-test * SMART error logging Security: Master password revision code = 65534 supported not enabled not locked not frozen not expired: security count not supported: enhanced erase HW reset results: CBLID- above Vih Device num = 1 determined by the jumper Checksum: correct -- Linux: For the people, by the people.
