ReadyNAS Duo v2 - no partitions
Hello,
some weeks ago I had to replace one defective harddisk. Then after the sync (RAID 1) everything ran without problems.
Some days ago the Netgear tool shows "damaged root directory" and does not boot.
So I tried to connect the harddisks to a computer but I cannot see any partitions on all the three (one defective, two working harddisks) harddisks.
A partition recovery with testdisk also does not help.
Normally there should be some partitions (at least one LVM) on the disk, shouldn't?
Thanks, a lot.
UFS Explorer 5.26 also worked fine to recover all the data.

You should see partitions in the Windows Disk Manager, but of course you can't mount them w/o linux tools.
How large are the disks? Some older USB/SATA adapters fail with disks > 2 TB.
What firmware are you running in the NAS? I'm asking because it's important to confirm the model (the labeling is confusing, and many v1 owners mistakenly think they have a v2).
A v1
- says ReadyNAS Duo on the front chassis
- runs 4.1.x firmware
- might say v2 on labels on the side or back.
A v2
- says ReadyNAS Duo v2 on the front chassis
- runs 5.3.x firmware.
TestDisk claims to understand MDADM and BTRFS, but may not be looking for a BTRFS file system on an MDADM RAID. I just hope it found nohing ir knew what to do with, and thus wrote nothing to the drives. Otherwise, it could have made things worse.
Ok, I have a A v1
- says ReadyNAS Duo on the front chassis
- runs 4.1.x firmware
- might say v2 on labels on the side or back
On backside there I see ReadyNAS Duo RND2110 v2, default FW was V4.1.6. now there is the latest on it which was available for this device.
The harddisks has a capacity of 1TB (I tried it with an SATA2USB adapter and directly via SATA inside a computer).
In former times I recovered data from any other ReadyNASDuo v1 and there I could saw the partitions with fdisk or testdisk.
I find it strange that none of the disks have any partition on it.
Which tool do you suggest me to mount one of the disks?
