External Hard Drive Question

[Walczyk]

I'm buying a My Book Premium hard drive (probably) and I was wondering if I can use it interchangably between a mac and a pc. So I guess the bigger question is can either OS recognize and read the other's filesystem?

If you format the drive with FAT32 they can both use it, as opposed to NTFS (XP's default) or HFS+ (OS X's default)

OS X has some NTFS support, but it's touchy at best.
