I bought a few new hard drives recently. Before installing them into the computer I decided to test them a bit (good idea!). I noticed that one of the drives was packed in a non-sealed wrapping and its manufacture date was last July. I looked at its S.M.A.R.T. information and it reported 4390 hours on power.
I complained on the seller’s hot line. They told me that the drive came directly from their supplier. I don’t know whether it’s true, they should notice the non-original packing but I didn’t notice it either until I’ve started unpacking the drives. They suggested to return the drive. So I claimed it at the shop and they exchanged the used drive for a new one.
Apparently there is another dirty business practice somewhere. So when buying new hard drives, be more careful than I have been at the shop.
