Glad that you have identified the issue, a format on the Mac should enable you to backup to the Mybook you should not lose any data unless you are very unlucky and get a lightening strike or similar during your backup!
I use Roon with my 861v8 with an ID41 and an MS600, my MD600 fills the bottom shelf of my rack, it is not powered up.
