  • Newer HDD, write error count failure

    I purchased a WD 750GB HDD 35 days ago and tested it thoroughly before trusting it. I completely filled the drive with data, erased it then ran burnintest for 6 days straight at a speed of 3MB/s. All this time diskcheckup was running and no change in the smart values. Yesterday the write error & reallocated sector counts started going up. This morning my PSU died and I replaced it with a lower wattage one I had lying around. Today those values have grown exponentially.
    So do I need to go though the long process of a factory RMA immediately or has a failing psu and possible underpowered psu caused a minor damage with a high error rate?

    DiskCheckup Version: DiskCheckup V2.1 Build: 1001
    SmartDisk DLL Version: SmartDisk DLL SDK v1.0 Build: 1013

    Addition, I have been heavily accessing this drive in the last 2 days to recover a clients raid0 stripe so it has had several periods of several hour long full load.

    You have a fail on the Reallocated Sector Count. Which is fairly serious. Don't trust this drive anymore and make a good backups.

    In my opinion the drive should not start if the power is not good. But I guess a loss of power or brown out after booting might damage the drive. You would need to check with WD, but I don't think you will get a good answer from them.

    I think I would still try and exchange the drive however.
