MyBookWorld 2T 'Blue light' What can I replace the drives with?

I don’t know specifically which sizes are acceptable. However, your odds are better for 2 TB than for 3 TB. Whether larger will work depends on the hardware interface and the flavor of Linux the box is running. I know of a Debrick Guide on this forum for My Book Live and MBL Duo.

There is also a third party app which specifies single drive White Light My Book World. Some of this will depend on your comfort/skill level in Linux.
