ReadyNAS Duo: Bad disks detected
My parents' NAS stopped responding over the HTTP admin interface, wasn't showing on the router as being currently connected and wouldn't shut-down by holding the power button in. A couple of days prev...
Try installing linux reader on a Windows PC, and connecting disk 1 of the NAS via a USB adapter or SATA. If the data partition is intact, you might be able to recover the data. If there is no data, then repeat with disk 2 (depending on the history, disk 2 could possibly be the parity disk). Linux reader can be found here: http://www.diskinternals.com/linux-reader/
Also it is worth checking the disks in a PC using seatools.
BTW, power down the NAS before removing the disks.
As far as what happened goes - it sounds like the unexpected shutdown corrupted the OS file system at least. RAID is not guaranteed to protect against that. I lost my data volume once in my duo when I accidentally pulled the plug. (I had backups so no real harm was done).
