It is not an generalization, but for me, the HDD from signature are the first Seagate.
I can not be optimistic about this brand any more - after just 6 months I lost a drive.
And I hear a lot of people having problems with Seagate (not ES.2 like me).

Anyway, a hard drive is consumable, mechanic, that's it! We should care about all the data and do often a backup copy. I'm glad that is not a worse problem with my computer after I noticed that no longer work.
