Hello all, I recently purchased a Mac Pro off eBay. My Mac Pro has 4 Hard-Drives on it. 4 - SATA Hard Disc Drives - Drives 1,2 & 3 250GB each and Drive 4 is 750GB I have uploaded three screenshots. One of my "system profiler", one of my desktop, And one of the dashboard app - iStats Pro. The current OS is Tiger. THE QUESTIONS: Why is it only showing up 3 Hard drives? (Archive, Backup, Goodwill) [The Iomega is my external so it doesn't count as the 4) Also, I am a video major, along with photographer as a freelance job. MY question is. How would you guys suggest I work around my 4 Hard-Drives for storage? Should I have 1 drive dedicated to only software (installs) if so which one? How would you suggest saving content on the other drives? example: 1 drive for video, 1 drive for photo, 1 drive for audio.. ect ect ect. or one for backup, if so which one? I am sorry for all these questions. I am very familiar with what i do experience wise, and I know how to work my way around macs i love them) BUT this is my first experience with multiple Hard-Drives. Please take note that it says i have 4 HDDs but in the other 2 screenshots i supplied it only shows 2 This is probably something simple and stupid but Its a brain buster for me.
