In my drive's error log, I get a lot of `Uncorrectable error in data` errors and 'Media write protected errors' The total error count is 2534!
Have 1 re-allocated even count but no re-allocated sectors.
Here's the uncorrectable error log :
Code:
    Complete error log:

    SMART Error Log Version: 1
    ATA Error Count: 2534 (device log contains only the most recent five errors)
            CR = Command Register [HEX]
            FR = Features Register [HEX]
            SC = Sector Count Register [HEX]
            SN = Sector Number Register [HEX]
            CL = Cylinder Low Register [HEX]
            CH = Cylinder High Register [HEX]
            DH = Device/Head Register [HEX]
            DC = Device Command Register [HEX]
            ER = Error register [HEX]
            ST = Status register [HEX]
    Powered_Up_Time is measured from power on, and printed as
    DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
    SS=sec, and sss=millisec. It "wraps" after 49.710 days.

    Error 2534 occurred at disk power-on lifetime: 15344 hours (639 days + 8 hours)
      When the command that caused the error occurred, the device was active or idle.

      After command completion occurred, registers were:
