ReadyNAS Duo - RAID 0 - Disk failed
I have a ReadyNAS Duo V2 with 2 x 2TB disks. One of the drives obviously failed, as it was reported and then shut down. I have removed it from its bay.
Now since both disks worked in RAID 0, I wonder if there is any way to try to recover the data from at least still working HDD and in a best case scenario - from both.
Before you say that, I know RAID 0 is not a good idea. But that is a case here I need your help with.
RAID 0 is not a redundant RAID. If you have 2 disks in a single RAID 0, any disk failure causes you to have almost zero chance of recovering any data as the data is not redundant and is striped across the disks with no parity. If you have 2 volumes, each a RAID 0, any data that was on the disk that died is totally gone.
Depending on what happened to your old disk, you can likely consider cloning that disk. There are many resources online to help you with this. NETGEAR Support can try for a non-refundable diagonstic fee (see their articles on Data Recovery).
The file system on the Duo v2 is ext, so you might be able to get fragments of your data off but likely not large files.
My suggestion is clone your bad RAID 0 disk to a good disk and try restarting your ReadyNAS into normal mode.
Good luck.

Thank you kohdee - seems like a cloning is a good idea in my case. I will purchase a new disk and absolutely try to revive the entire storage that way. I will report the outcome anyway once I'm through with it.
