----- Original Message ----- From: "howard" : Surely you can format SD cards - all cameras have this capability, unless you did it via the computer's format process? of course you can format them, but that protected sector can be damaged and unlike a 'normal' drive you cannot format those sectors and be left with an 'SD' card - what you'll have is a card, but no 'SD' - no use :( read the wiki article and draw your own conclusions, but these disks are NOT simple, and errors will damage them permanently you can't copy that cryptic protected data back onto the drive to make it an SD card if it's wiped .. unless you're part of the mob who own licenses to the cyphers. : If this was a major problem, surely we'd have heard about it before? you'll see discussions about it on a lot of the portable user sites, places where SD cards are used in palms, mp3 players etc.. it's becoming a problem we'll all hear more about it in time k
