I have the kodak c310 and have tried all the following 128MB 256 MB and 2g none will format and gives file error why?

Hello and Welcome to FixYa!

Error e00100 means that the card is corrupted or formatted for another digital camera.Format memory card and see the results,Try to format the memory card using a card reader with the PC, if error still exists then it means the memory card is electronically incompatible and won't work The Kodak C310 uses MMC and SD cards and may be you are using SDHC memory card, In this case change the memory card,
I hope problem will be solved, if error still exists then contact to Kodak Cameras service providers.

I hope this solution helps you
Your token of appreciation in the form of Four thumbs and testimonial will be esteemed.

You could try formatting the card. There is a function in the camera menus to do this. If it won't format or gives an error when you try, then there may be an issue with the connectors in the card slot or the card may be incompatible. If it does format, all the pics will be deleted in the process.

If you have an existing 128Mb RAM module and inserted another 128Mb to give you a total of 256Mb and it stills shows 128Mb. Then the second RAM module may not be compatible or the second RAM module is faulty.
Try and use the same make and type RAM module as the original or insert a 512Mb RAM module instead of two 128Mb RAM modules. There is not much price gap between 512 and 256 Mb RAM.

I assume you installed another 128Mb of RAM to give you a total of 256Mb.
It is most likely the 2nd RAM module is not compatible with the other RAM module. Try using the same make.
OR
Purchase and install a single RAM module 256Mb or 512Mb these are not expensive.

Go into the camera menu and find "reset"...follow the on-screen instructions. Then, try to format the card again.

The c310 will only accept SD cards up to 2GB.

You haven't said which card you're trying to use but the symptoms are typical of those encountered if you try either a larger capacity SD card (which go to 4GB maximum) or if you're trying to use a later SDHC (the HC means High Capacity) card. The c310 was designed and manufactured before SDHC cards were manufactured and is incompatible at the basic hardware level. SDHC's will fit inside as they have the same form as SD cards, but your camera is unable to use them.

If you have tried using the wrong card then all you need to do to fix the error is to replace it with a standard SD card not exceeding 2GB. In practice you'll find that your camera may have issues with some brands/models of 2GB SD cards but that it will work fine with any make or model of 1GB SD card. The smaller capacity card will also ensure that your camera does not become awkwardly slow in operation.

Hopefully I've answered your question; all I ask in return is that you return the favour by rating my answer.

Hi I am Vortash It sound as if you have a damaged pin on the sd card reader within your camera , and it is not reading the cards id correct . It may be just a result of dirt on the pins ( grease from hands touching the sd cards causes problems ) simply try spraying the inside of the sd card slot with a good quality electronic switch cleaner , then put the card in and out a few times to rub the contacts . ( Clean the sd card with the switch cleaner and a clean cloth or tissue first )
CAUTION when spraying the sd card slot make sure the batteries are dissconnected and give the camera ample time to dry before re inserting batteries ..if this fails then a service department will be able to check the reader out for you . ..Hope this helps regards Vortash

If it's the Radeon 9600 Pro PC & Mac edition it has 256 MB DDR.

Older C310s won't take that large a card. Try to exchange it for a 1 GB or smaller. I had the same problem - a PNY 1 GB works fine

try to format using a card reader through PC...
