How to partition and format an external hard drive for Mac OS X
I have an Apple PowerBook G4, and I wanted an easy and inexpensive way to backup my data. I heard all these great things about external hard drive enclosures and how you can buy a cheap hard drive and then effortly hook it up to your computer using the USB port. So I purchased a Vantec NexStar external 3.5" hard drive enclosure (which is meant to be compatible with Mac OS X) and a Samsung Spinpoint 120 GB hard drive. That's when the frustration began.
To make a very long story short, Apple's own Disk Utility was unable to initialize partitions in the Mac OS (HFS+) format, but ironically, but worked fine with the Windows FAT32 format. All hope was lost (and a lot of time, for that matter), until my roommate found an article posted at . With some tweaking, here is the solution.
Let's suppose you would like to create two partitions on the new hard drive, one in HFS+ format, and the second in FAT32 so you can share your files with your Windows friends. Note that I am currently running Mac OS X 10.3.9. These are approximately the steps I followed to format my drive properly.
