New HDDs failing in Pro 2
Hello, I've been running a ReadyNAS Pro 2 with two 2TB WD red drives. I primarily use it as a backup and media server. I recently bought two 3TB drives (also red) to expand. Along the way I did somet...

With one old drive in, everything else (except for the few corrupted folders) seems to be working well - I can access all other files (at least the ones I tried), and can stream movies on Plex to my phone from both the drive and from an attached USB drive.
I'm not sure what the underlying issue is.
Options I see are
(a) try again on the new hard drive install/expansion. That might work, but some file corruption likely remains.
(b) format one of the 3 TB drives in a PC, and copy the data off the NAS to it. Then remove both 2 TB drives, and do a factory install with the remaining 3 TB drive. Reconfigure the NAS, install your apps, and restore the data from the copy. Then move the 3 TB drive from the PC to the NAS. This will take longer, but will ensure that everything is clean when you are done. You'd also preserve both of the 2 TB drives.
Do you still have access to your data?

The first problem was that as an external drive, 3A only showed as 764GB.
That's almost certainly because your enclosure doesn't support drives > 2 TB.

5. After some time I got a message that disk 2 was dead. Strange because it was new, and had no errors via SMART+. I removed that disk and the error message persisted even after rebooting. Yellow light on Raidar, flashing green light on the NAS.
If you still do have access to your data, then try reinserting disk 2 with the NAS running. It should attempt to add it to the array again.
If that fails, try connecting it to a Windows PC (via sata, since your enclosure can't handle the drive), and use the short test in WDC's lifeguard software to verify the drive. If that passes, then use the write test - the quick version is good enough to unformat the drive. Then try adding it more more time to the array.
Overall - the NAS will wipe drives before it adds them to the array. OS 6 systems will warn you if the drive is formatted, but OS 4.2 firmware will not.
