really having problems with adjusting size of exFAT partition called 'FAMILY' in my 1TB Buffalo drive. There are 2 partitions, the first partition is Mac Os Extended Journaled Encrypted, I believe (it does 'only' show 'Mac Os Extended (Journaled)' but it does require a pw to access when connected to my mbpr). It is called 'JEDI'. Its size was ~ 1TB, when I added the exFAT 2nd partition by clicking “+” on the bottom left of the 'JEDI' rectangle, the 2nd partition takes up 499.93GB. I would like to have the exFAT sized 820GB, is there anyway of doing this?
