Upgraded 1100, can't mount /c

We upgraded one of our 1100s to 4.1.9 and it wouldn't boot after restarting. We tried a flash-from-USB, which was successful (in that we were able to flash the firmware) but the unit still won't complete a boot.

I've since pulled the drives and put them in an NV+ chassis (which works) we keep for testing/recovery. On the NV+, it gets as far as "Booting..." and I can SSH into the unit, but Frontview doesn't come up, the volume isn't mounted, etc. I've tried pulling each drive in sequence to see if any one of them was blocking boot, to no avail. The LEDs (drive 1 blinking, 2-4 steady, power pulsating) seem to indicate the drive in slot 1 is the problem, but the presence/absence of that drive makes no difference.

We have a backup (which I've restored to the 1100, after putting all new disks in it) but I'd like to recover the past day's work. If I can't do it via the ReadyNAS itself, is it possible to mount this volume on a x86 Linux PC? I've seen notes on how to do this with fuseext2, but I'd really rather not go that far.

dmesg shows the following.
