i think when we format, we meant format the cf card in camera...its generally the preferred way
My Canon A700 is able to do low-level format. But I don't use it, unless the card still cannot be read after normal formatting. Normal format just overwrite the FAT (file allocation table).
I sort my pictures according to date in my external drive, hence I'd cut and paste the files most of the time. "Cut & paste" is actually a copy followed by delete.
Oh ya, I'd definitely format the card if it's previously used on a different camera.
The other type I doubt is low level format, I think the camera just write a pre-determined pattern to the memory. In doing so, the camera can tell whether there are bad sectors and therefore can mark those areas up and not write to them. This will avoid the potential having corrupted images later on.
To maintain maximum compatibility between the DSLR and the CF card, I format my CF card before every shoot; after downloading them to the computer of course.
I download, then check the download. Then format (format takes 2sec or so).
I think of it the same as why it is good to defragment a hard drive.
Time, is an effortless construction :)
Just format. It's the fastest.
I always format too.
Thanks for all your feedback! Looks like re-formatting is the way to go.
As advocated by my sensei....reformat and then reset...after each day's shooting.
Aussie Slang may sound offensive, it is the way we speak and not intended to offend.
I always reformat my memory cards.
