January 31Jan 31 Hi guys. I am finally moving to Unraid from a Netgear RN214. I have watched multiple youtube videos. Here's my issue. I have photos and movies saved on to sata drives that were in a Raid 1. I tried mounting one of the drives and it would not mount. So I searched around and again and AI advised 2 mount both drives. So both drives were connected to my array physically and still the same problem. The syslog says:unassigned.devices: Mount of 'sdc1' failed: 'mount: /mnt/disks/50333c54:0: unknown filesystem typeWhat can I do to make it mount?
January 31Jan 31 Community Expert Can you assign them to a new pool instead of using Unassigned Devices? Might have to New Config.
February 1Feb 1 Author I placed them in a pool of devices. When the array is started it says they are unmountable. When you say New config, what do I have to do to access them? So I want them to be accepted so I can access the data and move the data to the array. Is it possible to add the drives without formatting them first obviously keeping the data?

February 1Feb 1 Community Expert Looks like you did it correctly, must be something about them that Unraid doesn't recognize.What do you get from command line with this?fdisk -l /dev/sdc

February 1Feb 1 Community Expert Unraid doesn't support the standard Linux MD RAID driver, you should be able to mount them in a Linux VM if you need to copy the data.
February 1Feb 1 Author Ok so I have a VM running Ubuntu. How do I get the VM to interact with the drives I have as pool devices in my unraid server?
February 2Feb 2 Community Expert They must be unassigned from the array or a pool and passed through to the VM. Make sure you use /dev/disk/by-id/ instead of /dev/sdX since the latter can change
February 14Feb 14 Author Solution Thank you all for your replies. I ended up just connecting the drive back to the WD board. It turns out there is hardware encryption with board in the external drive. As soon as I attached it back and connected via usb3.0 it was able to mount. The speed is painfully slow but I was able to copy the data over.
