Best way to move a 300GB Exchange 2013 database to a different drive?

Ok, hopefully this will be the last Exchange question for a while.

What is the best practice for moving a 300GB Exchange DB that I KNOW has corrupted items.

Unmount and then Move-DatabasePath, or should I use an alternative method? (And can you add a BadItemLimit to a Move-DatabasePath?)

I just want this to go flawlessly and have options in case one option fails.

Thank You,
