ST2000DL003 Barracuda - 2TB

I bought 4 of these to go with my new Ultra 4 having just consulted the HCL and before seeing this thread. When the system started building I got an error saying that the system could not build properly. I opened a matter with Netgear and set to work again (late night of course). When trying again it just said that one drive was not working. I removed that one and it built just fine. In the meantime I had read this thread and was quite reluctant to backup all of my data from my old NV+ to the new Ultra. In the morning, I called Netgear support and the guy actually told me that "we do not recommend that drive with the readynas and we are trying to get if off the HCL, but it is also sensitive as Seagate and Netgear are working hard to get it to work". I asked him if I should return the drive, and he said it could be a good idea. So I did, and bought 4 Hitachi Deskstar 2Tb instead. The Netgear guys said that they had the most problems with cheaper drives from Seagate and Western Digital but that Hitachi and Samsung drives worked better.

One of those drives was DOA and was replaced on warranty and since it had been discontinued, I now have 3 Hitachis and one Seagate Barracuda ST2000DM001 and it seems to work.

I would strongly advise against the ST2000DL003.
