I posted this in the external hard drive thread first, but I'm guessing that doesn't get much traffic usually seeing as there's a couple of specific threads on hard drives that are active.

I'm looking into buying a 1TB LaCie. Amazon has one with great reviews on sale for $245 Link. My questions are: 1) I would like to be able to play movies I put onto the HD on my PS3 when I connect it via USB. Should there be enough power to run the HD? 2) From my understanding, I will have to format the drive in FAT32. Will that be okay for running on my mac when I don't have it hooked upto my PS3? I'm not sure what the benefits/downsides would be. I plan on using this with Time Machine, also...

Thanks.
