I have a memory card that still has memory an my camera is telling me to reinsert the memory stick

As a last resort you could copy the full card to a computer and then delete the pictures on the card and use that again.

Here is the error list from the camera manual.
This is all I can suggest from here.

Its a format error,Firts format the memory card

i have the same problem..
I have a Sony Cybershot DSC T70 and it keeps saying "Reinsert memory stick" whenever I turn on the camera or slide down the camera lid. Also, whenever I try to view the pictures on my laptop it shows "Please reinsert the memory stick" something along those lines. As I have been researching for the solution, I would have to format the memory card. However, I wouldn't want to lose the pictures as I just took many as from the holiday last week. The only problem is the memory card, I tried using another memory card and it works fine with the camera. There is nothing wrong with the camera.\r\nCan someone please help me how to solve the memory stick problem? It would be great. Ty.

Are the contacts on the card clean? Is the slide switch on unlocked?

The problem is with the memory card. It probably just shorted internally and is no longer useful. The amount of memory is not the problem, as I used a 4GB card for a long time and my card finally went bad. You will just have to get another memory card and MAYBE find someone to be able to retrieve your data.

I will forward a link to a page where you can get the information about this issue.

Also please check whether you're using a Compatible Memory Stick with the Camera.

It's not recommended to Format the Memory Stick in the Computer.
The Memory Stick should be Formatted in the Camera only, other wise such error messages can occur.

Please try using a different Memory Stick and check whether the issue persists with the other Memory Stick.
This is to check whether the issue is with the Memory Stick.

The memory stick could have failed as could your card reader. If it is the card reader you're looking at $75-$100 to repair
