Browse disconnected hdd in win7 from RN104 raid
Hi,
I've upgraded my ReadyNAS 104 succesfully from two 1TB drives (raid1) to two 4TB drives. Next I tried browsing this old 1TB on my win7 pc but unfortunately win7 doesn't recognise it. I've tried with DiskInternals linux reader 2.6, it can see it's a btrfs volume. But when I open it says raid array is damaged recovery is possible. But it seems it can only recover when both 1TB hdd are installed. I wanted to test this scenario where the ReadyNAS and 1 HDD of the raid is broken. So if this doesnt work I need to think about a new backup solution.
How can I browse my old 1TB readynas hdd on my pc?

Re: Browse disconnected hdd in win7 from RN104 raid
Did you try using a linux live CD boot disk?
You'd need to install mdadm and btrfs and then run a couple of commands to mount the volume. For instance
# apt-get update
# apt-get install mdadm btrfs-tools
# mdadm --assemble --scan
# cat /proc/mdstat
# mount -t btrfs -o ro /dev/md127 /mnt
Though it's good to test that this works, I suggest you ideally should have a backup of the NAS on another device (for instance an NTFS-formated USB drive).

Not yet I will try that right away thank you for the details.
How do you propose backing up a 4TB NAS on an USB stick?
I know NAS should never be seen as a backup. But I've tried backing up my nas to a webdav service. But the process took longer than 24hours for 1TB of data. And the Internet connection was not the bottleneck.

I never said a USB stick. I meant a USB hard drive. If you get one larger than 5 TB, I recommend connecting it to a PC, and running the backup job over the network - the larger USB drives (notably Seagate) are SMR drives, which seem to misbehave in linux systems.
Personally I back up my NAS to other NAS, and use CrashPlan for disaster recovery. In the past I have backed up NAS shares to dedicated internal drives in PCs.
