It does seem from the sound of things that your card reader may be faulty if it works OK with your USB lead to camera option. The reason for using the card in the card reader is two fold, first of all it is faster than USB especially with video files and secondly it saves your camera batteries which may be a problem in some cases. As to the formatting of memory cards it is entirely up to you, but just deleting images will only free up space on the card and therefore can slow up ‘save’ times between shots. Think of it this way, if you delete two 8MB images you have freed up 16 MB of space on the card, if you then took a 20 MB image it will have to use up the ‘freed’ 16 MB and then have to find another 4 MB somewhere else on the card to store the rest, this problem becomes exaggerated the more times you delete images from your memory card the greater this allocation of free space becomes. However do not assume that it will be a serious problem to you, it wont, although if you use video the problem can be exacerbated. Formatting a memory card will completely clean the data and each image will occupy the space next to the last image and so less prone to errors rather than have the data scattered all over the card which will be the case with constant deletions. As I have said to you all before, I only offer you the advice as I see it with hopefully enough information for you to decide what you prefer to do yourselves, I prefer to do a full format after several outings with my camera, but I don’t do it every time I use it, It all depends upon how many images I may have taken or deleted or if I have used my video option.
Kiya it looks like you have everything sorted now so fingers crossed that everything goes to plan, it should be a great holiday.
Even the train ride to Pompeii should be an adventure in itself, I have the travel brochures out as we speak.
