Direct access to a disk which was part of RAID 1
Hello,
my (QNAP) NAS is not working anymore and I need to access my data. I tried with some Recovery Software in Windows, but they can't see my directories structure. So I'm trying with Ubuntu.
There are two WD RED 8TB and I can connect one of them at time to my Laptop with Ubuntu.
Under Disks I see the volume has 5 partitions, all of them Partition Data: Basic Type and Content: Linux RAID Member (version 1.0).
fdisk -l:

Under files I can access md9 and md13, but not md1. How can I do to access it? I have to assemble?
Thanks a lot.
