I have 2 internal drives in my power mac, the 1st being for OS X and Apps, the 2nd being for all my audio. I am thinking about splitting my massive audio drive into 2 partitions using disk utility. Although i can't see any warnings, i'm worried that partitioning a drive with data on will erase the data that is already there. Am i wrong to worry? Or will everything get wiped? Your help would be great. thanx alot!!
