If the drive fails the HGST test long or short, then return it to the store to where you bought it or if you got it from an on line retailer then ask for an RMA to replace it
Well. You fixed the pending sector count and that's the reason that now you have more reallocated sectors. This means that all the bad sectors are now isolated but the drive is not reliable and needs to be replaced as soon as possible. It's dead mate
Yes i know tat, but it is very strange a HDD designed to be used in Enterprises Servers (it cost ~140€ + VAT) has arrived with that amount on BAD sector as new .
I wouldnt have thought so joe, factory refurb'd is tested unlike new stuff, i had a refurb hdd that went for years and i got a refurb power supply that works fine. DOA parts are a lottery.
Any bet the box was dropped by the couriers of by warehouse staff. Refurbished suck. Go back to where you got it from & get a new replacement...
Hmm I may be wrong but in my opinion in daily use an SSD with at least 200 GB is more than that enough for any Windows OS run 100%, the rest pour everything into a simple HDD for file storage
