    HD Tune showed error, now doesn't?

    First, I ran a successful erase verify test with HD Tune 5.0. Then I started the test again and it showed the first block as red and reported 1 error. After that I started the test again and it passed fine.

    The smart data shows no bad sectors or anything bad at all. This is a new Seagate 1TB backup plus external.

    I'm not sure if I should return it for replacement. I really need to know this drive will be reliable and this makes me very worried. :(

    And just because it's new means it can't be bad? I think not. But if I were you, I'd first go for the best two out of three. Run it one more time, for good measure.

    New means nothing to me, that's what DOA is for lol. The issue is, usually HDD's will fail consistently. I guess I can only assume that one time was a software error, cause I keep running the test and it passes.

    Are you doing quick scans or full scans of the drive and have your attempted using an alternative program incase?

    I'm doing the full "Erase" with verify option. That writes data to every block, then reads back everything written to confirm every block functions correctly. I just completed the full test without error. Now I'm trying another program called "H2testw".

    Every drive has reserve sectors that can be used to fill in if a sector goes bad. It sounds like your hard drive detected the bad sector during the first test, retired that bad sector, and reallocated a spare sector to fill in as a replacement. Sounds normal to me. Obviously the data that was on the bad sector is likely gone forever but if no other errors occur the drive is likely still in good health.

    Run a few more HD scans and use Eraser to write over the entire unused portion of the drive and exercise the drive a little. If no other reallocation events occur you probably don't need to worry about returning the drive. If the reallocation events continue then you likely have a mechanical problem and need to return the drive. I've had a few desktop drives get one or two bad sectors, reallocate spares to replace, and run perfectly fine for another 3-5 years.

    I'd do 24 hours of reading/writing with Eraser then check the drive's SMART statistics and run a health check with HD Tune.
