RN104 raid failed
I have an RN104 4 bay 2T in each Bay on a Raid 5 set up I had one drive degraded and put a new one in but it failed to build Have just moved house and on restart the raid did not mount. After a ...
Thanks for this
Yes i take your point on mounitng a new disk but the second fail happened long after the first i guess it didnt like being moved house.
Unfortunatly i didnt have a disk i coudlback up too at the time
The new disk (4) resync failed before the house move so i guess it must have retried again
The 2nd disk failed at 0716 this morning

I guess my only option now is Data recovery
seems odd it says the RAID is active but the volumes are not mounting
is it worth Destroying the Data-0 volume and rebooting ?

If you want to try and recover data, then absolutely not. The more you do, the more difficult data recovery becomes.
Options are:
(a) contract with Netgear, who will attempt recovery remotely
(b) use data recovery software - in which case you will need to be able to connect the disks to a PC
(c) use a data recovery service - in which case you will need ship the disks to the recovery service.
