    hda: DMA timeout error


    I have CentOS release 6.3 (Final).

    When I copy a large file (say above 1GB or so), I get the following error very frequently
    WARNING: Kernel Errors Present
    hda: DMA timeout error ...: 4 Time(s)
    hda: dma timeout error: status=0x48 { D ...: 4 Time(s)
    ide0: reset: master: error (0x00?) ...: 1 Time(s)
    What does this mean ?
    Is my hdd end of life ?

    Thx & Rgds,

    If the device you are copying to or from is /dev/hda:
    Yes, this device has an hardware issue.

    Thx @Irithori
    Appreciate your prompt help.

    Yes, I am copying files from & to the same drive.

    (1) Any way to test & confirm that the drive is bad? Any tool, script, test etc

    (2) On this HDD, I have Virtualbox installed along with 8 VMs.
    Is it safe (advisable) to simply clone the HDD (using clonezilla) on to another disk?

    Reinstalling & reconfiguring will be one long exercise, but if required, I will go that route.
    If simply cloning is safe, then I will be happy to use clonezilla.

    Best regards,

    I would shut down the VMs and start a file copy to a new drive.

    The advantage vs a image is:
    You already know/highly suspect a failed drive. So the image creation is likely to fail.
    A filecopy on the other hand tells you, which files are damaged.

    So first safe your data (VMs), then test that disk with the tool badblocks.
    Why do the test later?
    Again, you already suspect a failed drive.
    And badblocks by its nature is very IO demanding as it goes over the whole disk, potentially damaging it more.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    If this disc is S.M.A.R.T. enabled, open Applications->System Tools->Disk Utility and look at the SMART data. That will tell you if the drive is starting to fail. You may need to install the smartmontools package first.
    Sometimes, real fast is almost as good as real time.
