Risky Maneuver ?

OK so I've got a Readynas Ultra 6+ and in there I've got the following

6x Seagate 2TB drives
Model : ST2000DL003

I bought the NAS and the drives back in Sept and since then I've had 3 hard drive failures in the NAS, the first two I sent back to Amazon for replacement (despite me thinking they were actually fine) however my third drive failure which happened 2 nights ago I decided to test, I attached it to my Mac and decided to give it a test with drive genius, after repartitioning it using Disk Utility. I ran a bad sector scan and it found nothing. So I thought what the hell and removed the partition table on the drive and put it back in the NAS, the NAS has now rebuilt the disk again and hey presto everything seems to be working again. I've done a SMART check from within the NAS and I get the following details back

So what gives, is the drive knackered and I'm just on borrowed time, is my Readynas faulty and its reporting perfectly good disks as dead, or is there another explanation, I know I'm getting pretty sick of dead disk reports so what gives ?. All suggestions welcome

Were you seeing SMART errors on this drive were you seeing before?

No, but I just thought I'd add that SMART info to see if it'd give any clues as to why my NAS keeps failing my disks seemingly for no good reason, ultimately what I'd like to know is how do I determine why my NAS thought the disk was dead ?, how do I find out that info ?.

I have read reports on the forum recently that there is an issue with the drive firmware that SeaGate has recently admitted. This may be related.
