Formatting my MSDHC card?

I've been told that in order to play some of my games that I need to format my MSDHC. Problem is, when I go to format there's tons of ways and options to do it and the last time I formatted something I rendered it completely useless. So what should I format my MSDHC card to? Are there any special settings that I should format it to? Thanks, guys.

Use Panasonic Formatter.

Ah, thank you. I think I may be able to figure it out from here. If not, I'll be back with questions and whatnot.
