Formatting I had my camera and was taking pictures fine. I plugged my chip into my friends computer so she could have the pictures without me sending them and it worked fine. then i tried to plug it into mine and it wont work. so i put it back in the camera to see if i could see them then. and it says card unreadable. format card and i click format and it wont format.. helpp?

Plug it to a computer and open its files(explore) look for the file where your photos were stored and move them to your laptop/computer or flash drive from there you can send it.

Formatting on the computer should give you a better idea of the card's state dice you can verify the space afterwards.

Where are you formatting the card?...in the camera or the computer? It must be formatted in the camera. When you pull it out of the computer, do you remember to use the "safely remove hardware" function so the card does not become corrupted?

Try taking photos on a lower resolution. They use much less space on your memory card. But only 50 on 4gb means something is wrong.

Check to see everything on the card is actually a picture and not a video. Taking videos can chew up amazing amounts of space, after all a video is a huge string of photos strung together. I hate to think it but some time ago a conamn was selling doctored memory cards which read 4gb on your camera but actually held only 2 gb. I would've thought these could have been long gone but if you purchesed it used it could well be one of those. Although I'd still expect more than 50 shots.
Maybe your card requirers a format. If your camera has a formatting capability try it out, just make sure you do it with a known good set of fully charged batteries. If they die halfway through a format it can wreck your card.
Your camera should certainly allow more pictures to be taken on a 4gb card. Buy check the above and maybe borrow a card from a friend to try out or even a another card. A spare sure comes in handy and with today's prices they're as cheap as chips.

I would suggest formating the memory card through the options on your camera. If you reformat the memory card and you still get the same error then you have a bad card. Just like anything else the cards will break down internally over time.

Your camera is only supporting SD/MMC Cards (up to 2 GB) and KODAK SDHC Cards (up to 8 GB).
The card that you currently have might be faulty. Please try another card.
You might also need to switch the camera over to saving pictures directly onto the SD card.1: Menu, Cam settings, Chose AUTO or SD card option Press OK
Note: If the SD card isn't in the camera or is unreadable the camera will automatically go back to saving you taken pictures on the internal memory.

Use a separate card reader instead.

It sounds like the file is corrupted. Try formatting the memory card in the camera. This will wipe the memory card clean and eliminate it from the being the problem. Formatting the memory is erase the memory card and you willnot be able to get the pictures off it after you format it, so make sure you down load all you the pictures you want befor formatting the card. Then occasionallly after downloading everything, format the card on a regular basis. This will help to keep the cards internal memeory from being fragmented. If formatting does not fix the problem, try another card (format it before use) if this does not fix it, take it to a local camera store and let them trouble shoot the problem or send the camera off for repair.

Start deleting pictures base on how good they are, importance and priority. Then by trial and error delete 50 pictures, download; 100 ... 200. Finally it download ... after 10-15 seconds wait. Total pictures deleted 1700 out of 4200. So there is a limitation on this type of camera with a 2GB chip, you have to stop taking pictures and change camera
chip when the total count reach 2500 + or - 50 pictures.
