I have a mac pro 3.1, SSD boot drive (Samsung 840 pro), and multiple other drives are attached via areca 1880 card. I recently flashed my 680GTX to make it boot compatible and also flashed my SSD to latest firmware. After all this, I upgraded to mavericks. After upgrading, I am having VERY slow performance with frequent freezes and beachballs. When I check my Macintosh Hard drive, it lists system as read/write but everyone else as read only. And there is no listing for me as user. On every other hard drive it lists "name(me)" as read/write access. Is there something I can do to fix this - somehow it appears during the installation I've lost control of my hard drive. I tried clicking the plus and adding myself as read/write but then it says "custom access" above which is different than the other hard drives and I don't think that's right. Very frustrated right now, I'm really hoping someone can help me out.
