For "never" formatting your card in a computer as suggested by samueljay, I'd say why is that?
Especially if you're using the card with multiple cameras, for example I've gone from Oly E-520 to E-3 to Canon 7D and had a try with 1Ds MkII, I always format the card in the computer before putting it in a new camera. And when I do, I don't use the "quick format" option.
This is because every camera formats the card "in their own way" and I had a big problem when I went from the E-520 to the E-3 and formatting the card in the computer solved it. The camera would take a few photos ok, then freeze with mirror up and wouldn't reset until the batteries were taken out. So yeah, learned my lesson there.
I mean what's bad about formatting the card in a computer if you format it again when you put it back in the camera with it's own utility? For some reason I don't think new cards are formatted in camera when they ship out...
I format in camera so as that the card is formatted the way that that camera likes. As for using different cameras with the same memory cards, in that case, maybe formatting on a computer is a good way to go, but it's something I would never do. I would have separate memory cards for each camera (and I do for my compact and dslr and any other device).
Like you said, the camera format's "in their own way" I don't know if I'm being overly anal, but I've read it a bunch of times that it's better to format in camera as then the camera and card are both set exactly how the camera would like it.
To quote wedding photographer Jeff Ascough:
On the subject of reusing cards I never, ever, ever use the computer to format the cards - I always format the cards in the camera they are to be used in. Another thing I never do is delete files on the fly in camera as this is just asking for trouble. If you feel the need to do this, may I suggest you spend some money and buy some extra cards?
No, you're right, new cards are not sent our pre-formatted in camera, that would be stupid, what camera would they choose? And a lot of cards wouldn't even be used in a camera, that's why, when I get a new card, I format it in camera as soon as I put it in.
Whatever works for you though, since you swap cards in different camera's formatting on a PC is probably the best way to go about it since it's a uniform format that every camera should be able to read/write to.
