2x 2TB WD green in ReadyNAS Duo?

I would like to repeat a question that has been asked repeatedly about WD Green drives on the HCL, which as far as I can tell has not been officially answered by Netgear or the Jedi. This posting is inspired by the fact that I just had to replace a 1 year old 3 TB WD Green WD30EZRS which is on the HCL.

I installed 3 of these disks on my Ultra 6 Plus when I bought the unit a year ago. Since the disks are on the HCL, and since I didn't have a convenient PC with a SATA port, I ignored the LCC issue. After 3 or 4 months, all 3 drives showed LCC's of over 250,000 in the SMART status. Since WD states they only test the drives to LCC's of a million, I bit the bullet, put the disks in a suitable computer (a Mac Pro), and ran wdidle3 on them; this stopped the LCC's from increasing. All was well until a few days ago, when my readynas went totally dead (which I described elsewhere on the forum); after I resurrected it (with much appreciated help from Jedi Knight and other Wise Ones available on this forum) I found that one of the WD drives had increasing write errors in the SMART status. The readynas did not consider the drive bad, but I replaced it with a new Seagate drive (also on the HCL).

So.....can we safely use WD drives on the readynas? - the drives are on the HCL - and if so can we ignore the LCC, or do we need to have the means and expertise to run wdidle3. And, given that the drives are on the HCL, can netgear provide a more convenient tool than wdidle3, that will run natively on the readynas - either built in or an add-on? I have never enabled root SSH, for security concerns, but I can if I need to.

Thanks!
