Penguinbait, edit: someone helping me. I've got a 16gb internal and 16gb external card. I want to dedicate about 7gb in the internal for the system and the rest for memory. I've read Milhouse's examples and others but I'm so comfused by math(I'm dyslexic, numbers get reversed) can you help me with figuring out the numbering for my percentages? Thanks, Dan
