Sata Hard drive testing

[Thomas Anderson]

Hello Gurus,

I have been having problems with a drive (non-SSD) for a while now, but 
I would like to "identify" the problem specifically, so that I may 
perhaps be able to get the drive replaced.

Essentially, I have been experienced data loss, where nodes become 
unreadable, when I try to "fix it" with fdisk, it says it moves 
unreadable to the trash, basically deleting data.

I have tried reformatting the drive, writing zeros to it, and then 
temporarily the drive looks fine; but it's not! it's as if the drive is 
some how decaying: where it looks good, but then when you go to use it, 
the data later becomes unreadable.

Is there any kind of test I can execute on this drive to show it needs 
to be replaced??

Thanks!
