New Hard Drive Issues
So about a month ago, one of my hard drives started to fail with increasing Reallocated Sector errors. I bought a new hard drive and decided to go with a 4TB WD4000FYYZ which is on the hardware compatability list. New drive worked just fine.
So I noticed another drive starting to increase it's RS errors, I decided I just buy 3 new 4TB drives and be able to expand the volume (currently has 2TB drives). I ordered 3 new drives off of Ebay. But when I place the drives in the RN104, I don't get a resync. The dot under the performance tab is black. I tried all 3 of the new drives and they all act the same. None of them will resync.
I have attached these drives to my laptop using a eSata dock, and they show up and run fine. I have even ran WD diagnostics on them (long smart test) and all of them pass. The only thing I notice that is different is the firmware levels. My working 4TB drive is 01.01K03 where the new drives are 01.01K02. I have not found anyway to update the firmware on the new drives.
Thoughts or suggestions?
Thanks,
Rob

Are you using FlexRAID or XRAID?
Do you see a format button on the volume page when you select the new drive? If the drive is already formatted, you need to format it in the NAS before the expansion will start.
Also, have you downloaded the log zip file? That could also give a few clues.
FWIW, I have seen a couple of other posters recently who had a bit of trouble getting expansion to start. They ended up doing a factory default with all disks in place - which succeeded. Then of course they had to reconfigure the NAS and restore all the files from backup.
I noticed that the drives were extremely hot so I tested them again. As it turns out, the drives are bad. All 3 of them. And when I contacted the seller to say they had failed diagnostics, he did not even question it and immediatly refunded my money. I figured the price was too good to be true.
The WD4000FYYZ does run quite hot, so that may or may not have been related to the failures. A word of caution about using a USB dock is that most have no cooling except ambient air and the one I know that does, by Sabrent, has given me false failures with larger drives. Before I had a computer with available removable caddy space for drive testing, I always had a little USB fan directed on drives under test.
But given your circumstance, it does seem likely that the seller had reason to suspect the drives. I recently bought two that were advertised as "tested and in great condition" and one failed SMART right from the beginning and the other had a lot of re-allocated and pending sectors. That seller actually wanted them back, but did provide a prepaid return. Some sellers just either lie or really have no business selling items about which they have no clue. And they count on the buyer also having no clue how to proerly test a drive. My guess is somebody else bought the drives I returned.
