Memory card I inserted my memory card into another camera and it said that it needed to be formatted, before getting a chance to download the pictures already on the disk onto my computer. If I format, I will lose the pictures! Any suggestions?

Please don't try anything again, with the camera, before you have read this and you have all your pictures on the computer. Even when you have deleted all pictures there is a chance you can retrieve them. But saving one other picture can lower this chance. Formatting the card could narrow the chance to almost zero.
Remove the memory card from the camera and place it in a card reader.
Download the free software to recover your files on a memory card:

And run the program.
I hope you did not try anything with the camera or with the card, because with the software you can make the deleted pictures visible again. Please save the pictures to your computer as soon as the program shows them to you.
After you recovered the pictures, you better format the memory card, to make sure no bad sectors are on the card. (Format the card in the camera, not in the PC)

You need to clear your memory card by either transferring the photos to your computer or by formatting the memory card. If you've already downloaded the photos but failed to erase them from the card, formatting will take care of that.

I highly recommend this data recovery program called asoftech data recovery.It is a comprehensive data recovery program that support deleted recovery, formatted recovery, partition recovery and Raw recovery.You can use this file recovery to get your files back easily! Here is the link

1) Using new memory card. first connecting memory card to computer and format. and insert memory card to camera. making single shot. then connecting computer you see picture.
Memory card formating in camera may be not working computer or other device.

You said it in the last seven words "deleted the pictures off the memory cards" Once the pictures have been downloaded to the computer Hard Drive you need to Format the memory card. Formatting a memory card is done in the camera it is to be used which brings it back to a clean surface and compatibility. Your manual said that "normally" formatting isn't necessary which is a pile the bull left behind. I could go into detail as to why format but I'm trying to keep this short/
Here is a diagram to show you where the "format" menus is and what to do with it.

With no card in the camera, go into the menu and find "format"...follow the on-screen instructions to erase the internal memory. Then, insert your card and try it. You may have to format the card as well so download any pics from it first using a card reader if necessary.

Apparently, you used the internal memory before putting in the memory card. Now the camera only wants to use the internal memory. Here's the fix...with no card in the camera, go into the menu and find "format"...follow the on-screen instructions to erase the internal memory. Then, insert the memory card. If this is a new card, you will need to format it in the camera, too. If there are any pics on it, download them first using a card reader if necessary, because the card will be completely erased.

Hi,
Yes, you can get deleted picture back if memory card has not been formatted and memory card has been formatted wither by camera or computer, then no chance to recover picture files.
Download Pandora File Recovery, its free software, install it in computer, hook you camera with computer and run Pandora file recovery, select memory card in drive list of Pandora program and let it recover deleted files.
Hope these info will help you.
Thanks.

Did you use the camera to format the card before you shot any pictures. If not, the camera can't use the card and used its own memory to store the photos. Use the camera to format the card, then the camera can continue to shoot more photos and store them on the card. When you download them to the computer, remember to get the one from the camera too.

Hii

Insert your memory card into your computer's reader if you have one. If not, you can purchase a multi-format USB Memory Card reader from Amazon.com or Buy.com

2 Open up 'My Computer'. You should see it under the list of available drives.

3 Check its contents first to make sure that you have the right drive.

4 In 'My Computer', right-click on the drive and choose 'Format'.

5 Leave all the options as they are and click on 'Start'. This is a non-reversible process so make sure this is what you truly wanted to do in the first place.

6 Once the process is completed, take the memory card out and insert it into your Digital Camera or any other device. Try to browse to it to make sure it works fine now.

Thanks
