Hi there,
To be more specific about what I wrote in the subject line: I first bought two external hard drives as I needed them. I ran the diagnostic tool (I always do that before I start using the drives), I ran the extended test, and on one of the two hard drives I got the information: “Test found sectors that may be repairable.”
I have bought and tested approximately 40 hard drives the last five years, and only once have I had a new hard drive to fail the extended test. It got this “Test found sectors that may be repairable” message, and I did try the repair option and apparently the hard drive was fixed. But within a months the hard drive had failed completely.
So I didn’t like that message, and didn’t prompt a repair, but instead asked the online shop to get it delivered back again. However, when requesting the online shop to send back a merchandise that a customer claims to be defect, the policy of the company is that if they check a product and they find it to pass, they will charge a fee for $50-$100. (I live in Scandinavia, everything is expensive here.)
I wondered whether the support on that netshop would mean that it is acceptible with a few bad sectors on a hard drive, use the simple repair option, send the hard drive back to me and charge me a high fee, for a hard drive which I personally mean is has a weakness?
Anyway witha bit of anxiety I still sent it back.
But since I really needed one more hard drive, I placed another order on the same online shop. I actually bought two hard drives, just in case one of the two would show the same flaw when running the extended diagnosis.
To my surprise both hard drives had errors. The first one that I tested came out with the same message as described above (Test found sectors that may be repairable"), whereas the other hard drive came out even worse: " Too many bad sectors detected." The diagnosis program stopped in the middle of the scan.
Also worth noticing: On 2TB hard drives that have passed the test brilliantly, the scan has always taken 16 hours. But with the two that had the bad sectors (but that could be repairable), the tests took over 20 hours.
And with the last - and more defect - hard drive the test scan was also originally showing that it was about to take more than 20 hours to finish.
So to my question number one: Are we supposed to accept new hard drives that show some “bad sectors that may be repairable”? (I really don’t like that and will then instead definitely use the warranty where I am allowed to send back what I purchased within 14 days, if paying the postage myself.)
So do I have the right to get a new hard drive without having to use the warranty where I have to pay for the postage, but instead let the online shop cover the postage and let the service check the product for the same error?
That last hard drive that had too many bad sectors I mean is beyond question.
My question number two: Thee out of four hard drives that fail the extended diagnosis test. May it be that the whole party of a production has the same weakness?
Thank you for your input.
