Use one external hard drive for both PowerPC and Intel backup?

[samintx]

I have always used external HDs formatted in the FAT32 format interchangably with mac and pC. I unplug to mac and put on PC or visa versa. In facto I have to clean up two externals I have been using over the years and see what PC and Mac programs are downloaded.

I download .dmg files to my PC and then transfer to my mac. Works fine ...because half the time none of my macs will access the internet....whereas my PCs always do.
