Hi all, I tried searching but didn't see this subject. I have a PC and just bought an Imac which I love! I have a SimpleTech SimpleDrive external hard drive that I'm using to transfer files from the PC to the iMac. But on the Imac, the drive only allows read, not write. I guess because it's been formatted for MS-DOS. My question is: I think in Disk Utility I can partition the drive, but can't seem to figure out what will happen to the files I already have on there that are from the PC. I want to be able to put files on the drive from the Imac and also from the PC. How do I configure the external hard drive on the Imac using Disk Utility? HELP!!
