TidBITS offers a variety of suggestions for maintaining hard drives, but the secure erase trick stood out for us. This writes data to the entire drive and verifies that it can read and write data on every sector. If it survives the secure erase, then it's good for holding data. Check out our guide for full details on performing a secure erase.

The Care and Feeding of External Hard Drives [TidBITS]


    I know this is not entirely relevant to the article, but I REALLY like that external HDD enclosure! What make/model is it?


    would this not just cause unnecessary wear on the mechanical parts of the drive, which are the
    'weak link in the chain' so to speak?

    pretty much all of the HDDs i've replaced have been due to mechanical deterioration/failure
