Question about external hardrives....and thier formats.

If I hook up an external firewire hardrive, to a WinXP PC, thats been hooked up to a Mac/Apple machine, Will WinXP read it or ask to format the sucker?

Cause I have some MP3's on a mac laptop that you can set to work exactly like a external hardrive....And I need to get the MP3's along with some other stuff copied to my PC...

Laterz....

well, I don't know much about macs, but I'm guessing the HDD isn't formated in FAT or NTFS, so I'm guessing your SOL at the moment

Anybody else have any other ideas?
