Hey,

I had an array of 4 Seagate ST2000VX000 (SV35) drives. After using it for a while, three of the drives "failed".

Since it was a backup array, I dismantled it and looked at all the drives separately. What was interesting was that all three had few hundred bad sectors in two different places, and almost at the exactly same two places in all three drives.

I am now extremely curious what would be the most likely reason for this. A manufacturing defect (serial numbers are very close together)? Something in the environment?

I was able to "reset" most of the bad sectors and relocate the remaining ones so the drives now test OK, I'm still not sure however if this was a one time event or something that is bound to happen ...

Any thoughts on this?
