Should I buy this hard drive (used)?
Good day!
I decided to take a hard drive (used) at the auction.
Model HGST HDN724040ALE640, 4TV - interesting, there are good reviews on the net.
But the test results are confusing. The disc was released in 2014.
The seller claims that the drive worked for a little less than three months. ((
Screenshots are attached.
The question is - could the seller reset SMART and thus seek to "suck in" consumer goods?
I would be grateful for your recommendations.

Resetting a smart is not an easy task, so it's unlikely.
The difference in the date of purchase and time of work is normal. When buying disks for a raid, a replacement disk is taken in advance and put in a safe so that it can be replaced immediately when the disk dies.
For a disk that has been working for three months, there are already 5 relocated sector counts and non-zero error rates are already in question (although the errors could be due to the controller on the motherboard)
ps expensive drives are bought not because they are expensive, but because the reliability is slightly higher than cheap ones (this 'a little bit' is absolutely useless for the layman), this difference becomes critical when you have hundreds of discs, and the question of how often they need to be replaced becomes critical , because if this happens often, then the raid array will constantly hang in the rebuild state, slowing down the work and lowering the reliability.
Therefore, if you buy such a disk, then at a price much lower than the market for cheap ones, and this is noticeable at times.
I do not advise you to take the discs from your hands, there is no guarantee, and now the discs die exactly at the end of it or close to it. And if there is only one disk in the computer, and even more so, it dies with data, you won’t even return the money.
so this disk is already consumer goods, the most consumer goods, that is, despite the smarts, you sucked in the most consumer disk
in general, I have a bunch of Seagate disks for 2 and 3 TB (though not hitachi like yours), bought in 2013 for servers in reserve for quick replacement of failed ones. So, having lain in a safe for 7-8 years and being put into servers in 2020-2021 to replace failed ones, they work no more than 3-4 months. The most common problem is the spindle jamming at the disk that has lain for 7 years in a safe. Most likely, long-term storage of the HDD without periodic launches at least once every few months does not lead to good. Draw your own conclusions. I would not advise taking the 2014 CD
