Help swapping "dead" drive? [Case #15693780]
Hey all, I have an NV+ that is about 2 months old. I fired it up and loaded it with all of our data, backed up all files from PC's etc...it has 4 x 2TB WD Green Caviar drives at this point. All is wel...
Well, i'm not happy with the result but it's better than losing the data. I will report back when I have had a chance to follow through on this, but here is what i'm left to:
Buy 4 "compatible" drives. Apparently, the reason they only support certain drives relates to a resync command that the compatible drives have and others do not. This causes the NAS to report drives as dead even though they're fine. Now for the precarious steps:
CLONE these 4 disks using ghost or something similar to the 4 compatible disks. Insert the compatible clones back in to my NAS and pray all is well. Ugh. Buying 4 more disks to test this out does not sound fun, but if it will rescue my data, it is worth the price of admission.
The tech was confident this would work. Thoughts on this before I shell out for 4 new disks on the HCL? I am going for these:
WD Caviar Green WD20EARS 2TB -- Firmware 80.00A80, Model # WD20EARS-00S8B1, See Tech Bulletin http://www.readynas.com/?p=3690
My only issue appears to be the -00S8B1 - How can I track down this specific model number? I have 2 brand new WD20EARS-00MVWB0 disks here now. One was sent as the RMA replacement from WD and the other I purchased as a hot spare from newegg. Can I use these? I had one in slot 3 when he logged in to my machine to look at the logs and said that it was on the HCL. So i'm slightly confused.
Where can I grab some of the disks on the HCL? Do I need to go right to WD for that?
hey BigBearf, thanks for the continued info. the tech seemed confident my drives don't support the resync command, but I will give the TLER a shot on the "dead" drive and see how we do. I will report back when I have a chance.

LLCs are high. The highest on my 6 drives is 2467 and all of the others are under 1000. I would definitely see if you can use both WDIDLE and TLER on your drives. My last drive was the one that had a different firmware (see Sig) and it was not supposed to be able to be "TLERed" but it was. When I did it stopped the LLC escalation in its tracks. I would try both tools and also replace the original memory to eliminate any variables.
Hope this helps. Please post results.
