Formatting the SD card.

Hello!  I just picked up a Sandisk 8 GB class 2 card for my wife’s Fuze I got it at a good price $24.99…  It’s still in the package at the moment…  Can I just slide the new car into her player and use as usaule… She is not going to be swapping out cards. At this point it will be left in the player and will be used as expanded internal memory so to speak…  Can I assume this Sandisk card is format-ed at  Fat 32 from the factory?  Thanks!  George
