NV+ boot(?) issues - disks are clean
I started having a problem where my NV+ would freeze. It was kind of weird in that all of the LEDs would go out (even the power LED), but the LCD would stay lit with just general volume information on it. It wouldn't respond to anything I did to the power button. I unplugged it and left it that way, assuming I had a catastrophic failure of some sort. My suspicion was power supply, so I started researching that. Fast forward a few weeks and I go ahead and purchase what will be its replacement (516) and I pulled the NV+ out of its shelf to figure out what the problem was. I plug it back in and just out of curiosity, hit the power button. Much to my surprise, it powered up and began an FS check. It got to about 40-ish%, and then all the LEDs went out again, with the display frozen telling me it was at 40-ish% of the FS check. So I unplug it, plug it back in and hit the power button. Now it freezes before it gets to the FS check.
After reading these forums, folks seemed to be saying this could be due to a bad disk. I pulled all the disks and plugged them into a desktop for checking. The drives are WD RE3 1TB drives, so I used the WD tool. All drives passed the quick check, so I then ran the long tests. Many hours later, all of the disks _still_ check out. So now I'm stuck. I don't know what the problem is, and I don't want to risk further FS corruption. I have some older disks I'm going to put into the system later today and see how it behaves, but if the WD tools say all the drives are good, I'm guessing it's not a bad drive.
Any ideas? I had actually been working on getting an offsite backup going, but it takes a while to send 2TB of data offsite. That said, I'd really like to get this data back and onto my brand new 516.
Thank you in advance!

- Success! I put the 1TB drives back in and did an OS Reinstall to them and the thing booted back up, ran through a full FS check (fixed a few errors), and then was back online. I've even run some test backups to the 516 cleanly. I'll get all the data migrated to the 516 and then use the NV+ as backup for the 516. I may even upgrade to some 2TB drives to maximize how much data I can backup.
Happy ending, but what a ride... - Me again. The saga actually continued. I have no idea if others will benefit from this, but after a few days of copying data from the NV+, it died again. I had enough messing around with that, so I pulled the drives. I put all four drives into a Linux box I threw together, mounted the drives per the instructions here: http://home.bott.ca/webserver/?p=306 and started copying data. Somewhere along the line, the array froze and couldn't be accessed from the Linux box. I then grabbed some 2TB drives and used ddrescue to make a copy from the 1TB drives to the 2TB drives. One of the 1TB drives had an error that didn't seem correctable. Given it was a RAID array, I mounted the remaining 3 2TB drives (that copied cleanly) and spent about a week copying data from there.
With that copy complete, I'm now happy to have my data back. I then zeroed out the drives last night and put them back in the NV+ with the hopes of using it as a backup. After building the array, I let it sit overnight and the darn thing shutdown _again_. At this point, I'm pretty well convinced my NV+ is haunted. I suppose I'll try a full factory reset at this point, but it's really weird to be having a problem with, essentially, brand new WD Red Pro drives. - For what it's worth, I used the ddrescue instructions here: http://www.kossboss.com/linux---how-to-clone-a-disk-with-ddrescue---dnu-ddrescue-also-known-as-gddrescue---the-better-ddrescue-tool
- It could have been the bad drive all along...
- Nope. After several days of running a backup from the 516 to the NV+, it shut down again. I'm giving up on the NV+ at this point and marking it dead.
