My ATC2K that arrived today came with an Addendum to the instructions - so just in case anyone who bought one a while back didn't get the addendum bit... I thought I'd mention it...! It says that the camera might not function properly if the card is formatted in "FAT32", and recommends "FAT" or "FAT16" format (I have no idea what the hell the differences between any of those are!!!). Formatting is done by right-clicking on the drive in "My Computer". If everyone already knew that, just ignore my waffling!
