Format CF card or delete images?

Side note: I'm baffled that people still use FAT for anything.[/QUOTE]

I have to agree with you on this one as well but being a noob I can see a flaming coming on if I open my mouth

data can be recovered from reformatted disks until the data has been overwritten. In other words, a full format, where everything is overwritten with a zero, makes it extremely difficult to recover data. Places like the CIA will overwrite all of their data multiple times.

I understand that, except I though if I reformat my computer HDD, it would wipe everything out? I was laughing in December when I recovered pictures that I found a few from August.

I think the format question is a "Ford/Chevy" one - you'll get many opions both sides.
But in most photography books I've read the auther says they format in the camera.

I can say I've done both but do it in the camera regularly. Thats probably because of my old computer days with small slow hard drives that slowed down when the disk got fragmented and so you had to de-frag (or format it) regularly. I know that probably has no bearing whatsoever on a CF card - but old habits die hard.
