My Cloud Home Disk Swap

I have a failed My Cloud Home NAS. The Network Controller board has failed. The data is on a 6tb WD Red drive. All my files are ex2. If I purchase a Western Digital WD My Cloud EX2 Ultra 2-Bay 8TB can I simply swap out one of the drives for the one I have removed from the My Cloud Home and access my files? This is the older My Cloud with the Blue LED

@StuartRP
From your information you do not own a My Cloud Home.

Unless you just want to buy a My Cloud EX2 why don’t you just buy a docking station and see if you can recover your files that way.

Have already bought one but the software I am using is not too great at recovering the files. Diskinternals Reader. The NAS that failed is this one.

This is the docking station.

@StuartRP
Have you tried to view what is on the drive with the Linux operating system?

Yes, I can see the files but cannot transfer some of them
