Hi,I have had to restore factory defaults on my ReadyNAS Duo v2 NAS due to performance issues, so I copied all files onto a single internal HDD then removed this drive before performing the reset. Now I am trying to connect this internal HDD to my Macbook using a SATA-USB adapter so that I can copy the files from it back over to the other internal drive on the NAS. This is to prevent me losing the data on my drive as the NAS will reformat it when I insert it back into the NAS.I cannot get the HDD partitions to mount on my Macbook (I have tried OS X, Win 7 and now Ubuntu Live). The Ubuntu GParted application is unable to detect the filesystem on the HDD.Can anybody shed some light on this issue, and how to achieve this so that I can retrieve the data from the HDD. Any other solution would be welcomed if there is a better way of doing this.Many thanks,p4c970

Can you tell us how you did the copy, and how the disk was formatted?

I had two disks in my NAS, arranged as a JBOD. I used ssh to rsync my c disk to my d disk, then powered off and removed my d disk.I now want to mount my d disk on my MacBook using the USB adapter.Is this enough info?Thanks, p4c970

The issue is mounting a drive removed from a duo v2 in a laptop so that the data can be read from it, have I missed something with your link?

I wanted you to read that article to confirm you actually have a Duo v2.

Just from using it and also from when I bought it. I have used the NAS extensively, but for the sake of confirmation, I also validated it against your guide. It is a duo v2.
I am on radiator 5.3.8, the latest arm version available.

When you ran Ubuntu did you start the RAID using mdadm ?

# mdadm --assemble --scan
# vgscan
# vgchange -ay
# mount /dev/d/d /mnt

I didn't, no. I didn't realise it had to be started separately, but your post is jogging a distant memory though! I will give that a shot and report back. Many thanks.
