Need some help, please.....Had a WD Studio Ed II 4 TB HDD (2x2TB HDD) and it worked wonders. Decided to upgrade, using the same external case, with two 3TB HDDs. The 4TB HDD showed up with all 4TBs available for writing to. With the newer 3TBs installed, I only get 2.2TB total - when I should have 6TB total.

I've tried reformating the two 3TBs in the enclosure with Disk Utility/Erase/Security erase. After 13 hours, still 2.2TB..... I thought OS X 10.6 and up supported larger external HDDs.

 

can anyone help?
