Are you using Ubuntu, or something else? If Ubuntu, does it show in Disks utility, or fdisk? It may be present but not automatically mounted, as raid software may be confused by it now being external - bit of a guess there!
Kubuntu 13.04.
KDE Partition Manager can't see it, nor can fdisk. Indeed it's not listed in /dev/sd*
I think that means that what is now showing up as sda1 is Spare - it can be part of the raid array, but isn't currently.
OK, thanks. I'll do some more digging.
I'd suggest that you continue backing up everything you can.
Strangely, an rsync of everything onto another server completed without errors. That makes no sense. I assume that some of the files are corrupt and have been copied as such but I haven't found a good quick way to test them yet (VirtualBox VM disk images).
Then, I'd suggest you disconnect both sdb (the original one) and the new 2TB disk. Reinsert the original sda back into its original place (i.e. not in the caddy). Reboot and see if the raid array restarts but in degraded mode (i.e. it knows it's missing a disk).
Sounds like a reasonable plan, I'll give this a go.
I hope/suspect it's sdb that's been causing the problems.
I share your hope but not your optimism! I'll let you know how it goes.
