I just recently found the removeable disk function on my Creative Zen, its formated in FAT32 and can be changed for size, would it be a good idea to put DSL or another portable Linux O.S. on there and is it possible to format it to FAT and it not crash?

I also just went to staples and picked up a discount (yeah bad idea all around but for 10 bucks its worth a shot right?) its a 64 mb and is formated in FAT and wont hold the dsl-embedded file when unziped even though the size of the file is smaller then the capacity of the drive :S can anyone give me advise, or some help on this?
