My SanDisk memory card for my HP Photosmart R740 wont let me format the card or delete photos from the camra or take new photos, please help!

Try formatting the card. Deleting photos leaves the card fragmented, and if you go through several cycles of shooting and then deleting, cards can become all but unusable. You should format the card every time you finish download all your photos.

Hi,

If you are receiving a "The card requires formatting" message do the following:

Press ( ) to display the Format Card option in the Delete menu. This will delete all data on the card.

it needs to format it to allow it to read by the camera...a sort of hand shake..so format it and go shooting

i have a hp 7.0 mp photosmart digital camera and when i turn it off the lens gets stuck half way and it gives me a message to look up code r740-022 can you help please thanks.

when you format you camra you can not retrive the picture you lost, you best way is to but a SD card from your local wal-mart and save you pictures on that in stead of you camras hard drive.

Try taking the SD card out then plug the camera into the p.c then format the internal memory.

Does SD card work in PC? HP R707 will not work with SD card larger than 2GB.

This has happened to my wife's camera twice now. The solution (I think this is the fix) is to take the card out of the camera and then turn it back on without the card in the camera. Doing this will access the camera's internal memory and at this point you should delete any/all/some of the pictures that you find. After deleting some pics from the camera then take a picture. Now turn the camera off and replace the card. Power on the camera and either format the card or just start taking pictures again. I formatted the this last time since I had already moved the pictures to the P.C. and saved them. Give this a try. It's worked for me and it's free.
