2 WD Thunderbolt Drives

I have a 4TB WD I got over a year ago. I have it stripped and formatted to Journaled on my MBP -OS 10.7.5 - 8GB of ram. 

I got another 6TB WD drive and formatted it and anytime I plug it in, I get a message saying that “The drive inserted into the system is incompatible with your My Book Thunderbolt Duo and will void your warrenty. Please go to www.wdstore.com to purchase a compatible drive” 

What the **bleep** is this? I never got that message before with my old 4TB My Book. Do I need to return the new 6TB My Book? anyone else ever have this error? 


Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
