I’ve used a 6TB MyBook Thunderbolt Duo with my MacBook Pro Retina for over 3 years, and it’s been great. I’d like to replace both 3TB drives in the enclosure with larger ones if that would work. Anyone know? Anyone tried to do it?
Hello and welcome to the WD Community.
Not sure if that’s might be possible, although, some users were able to do that on a different unit.
