    What does it mean if HDD fails on Random seek (8MB) test? Is it bad? Cause all other tests are successful.

    Later I tested this HDD with Western Digital diagnostic tool "Data Lifeguard Diagnostic" and it passed.

    run a sector scan and as you have the pro version run the full sector scan and not the quicky. will take a couple of hours.

    strange. oh well then thats a good thing but i have no idea what the random seek error can be.

    is it still covered by warranty. if not by your supplier then by WD themselves. some hard drives are covered upto 5 years.

    check the drive serial number and and enter it on the WD site and it will tell you if its still covered WD - Service & Support Home

    I'm not sure how the 8 MB random seek test come into play with your make and model of drive; it might not actually literally be "failing". For example, I've had optical drives fail the DMA test prior to burning an image to disc in InfraRecorder; nothing was wrong with the hardware and the burn was successful.

    Couldn't find specifics on that test for you, but perhaps if you contact WD they can let you know why it "fails" that test and perhaps reaffirm that there's nothing to worry about.

    I contacted them and now look forward to a response.

    The funny part is that I tried to test it again and it passed. The only difference is that before it was completely formatted and now it has an operating system (Mac OS X).

    But now I have this warning now:

    Now I don't understand what's going on here.

    DMA = Direct Memory Access. It is a feature that allows certain hardware components to access memory directly, independent of the CPU. I'm not sure whether laptop boards and/or this drive support DMA, but it failing that test does not entail hardware failure.
