Hard drive failed, re-formatted, is it ok?

Hello,
I have a WD 3TB hard drive that failed. (Lost a ton of stuff...) It has been re-formatted, and now boots up. Had a lot of bad sectors found. Is it 'bad' or now that it shows up is it use-able again?

  1. I'd RMA it ASAP and not trust it with anything.
  2. Did you do a low-level format? I would recommend that vs. a plain formatting. Low-level formatting usually restores the HDD to factory-like settings, as it zeroes the whole HDD. Plain formatting just marks written blocks as available; some old data still remains on the HDD until it is overwritten.
    A good read:

    There are various tools to perform a disk wipe, I usually use Killdisk.
  3. i have also noted that the larger the HDD capacity, the less reliable they are in single-disk data back-up solutions. I limit myself to 1.5 GB, and even then I prefer to use a RAID 1 configuration. For larger capacity HDDs I would ONLY use a RAID 1 solution. I have "burned" myself before, so I speak from my own experience.
  4. Thanks to all. I don't know about the format, I had a more 'computer saavy' friend do it...

    house70: are you recommending not using a 3TB?

    Thank you.

    Not without a RAID 1 setup. That would require a second HDD of equal (or larger) capacity and an enclosure that supports RAID1.
    They don't have to be fancy or anything. I use Synology for mine. I know you can build a network-attached-storage (NAS) system from scratch, but usually ends up more expensive than a plain 2-disk enclosure.
    As I mentioned, in my experience, the larger the HDD, the less reliable on a long run they are. Everyone's mileage may vary....
