    Input output error on read /dev/sda

    This all started when i install kubuntu 10.10 on my Western Digital Hard drive. It installed perfectly but one day i was not able to boot to kubuntu. so i tried to install it again but got the error

    "INPUT OUTPUT ERROR ON READ /DEV/SDA"
    and installer is not detecting windows partitions

    I have 120G western digital wdc wd1200bevs-22rst0 hard drive.

    I have tried following commands
    1) fdisk -l
    this doesn't detect my hard drive
    2) sfdisk -l
    read error. cannot read sector 0
    3) Gparted live cd
    input output error
    4) test disk (gparted live cd)
    read error
    5) test disk(windows version)
    no error detected
    6) smartmontools
    completly passed.no error detected
    7) windows is saying that hard drive is healthy
    8) even the manufacture's life diagnostic tool says that hard drive is healthy
    9) tried to burn the cds at slowest speed and even with usb stick . no luck
    10) completely wiped the hard drive
    11) tried the alternate cd but still no luck
    12) used 'fsck' but still failed

    I have tried ubuntu, xubuntu and kubuntu 10.10 and 11.04 but no luck

    I have tried the above things and still no succes . if anyone can help?

    thanks in advance

    AHCI is not a property of the drive; it is the native mode of the SATA controller.

    Did you actually run the SMART long selftest? How about posting the actual SMART attributes? Also check your dmesg for errors.

    The attachment provide the output of demsg command. As for as AHCI is concerned my BIOS donot provide option for selecting the particular mode. Yes i have done that self test and I will post the result of smart test soon

    Thank you for help

    It looks like the controller is boned. Do you have another computer you can try the drive in?
