Digimax 4010 Digital Camera: reads card error...

You need to get an SD card. The 4010 works with SD and MMC cards. Your 4GB card is an SDHC card. While it fits into the slot it's electronically incompatible and will not work in the 4010. You need an SD card, 2GB and smaller.

From your description, it sounds like you're formatting the card in your computer and then inserting it into your camera. Camera cards must be formatted in the camera only.

SDHC is an extension of the SD standard that extends the capacity from 2GB to 32GB. It's backward compatible in that devices designed for SDHC cards will also work with SD cards. It does not go the other way---that is, SDHC cards will not work in devices designed for SD cards.

I presume you mean a 2GB card, since a 2MB card might hold one picture.
The Digimax 4010 works with SD cards, not SDHC cards. You may use an SD card. Just make sure it is an SD card, 2GB and smaller. SDHC cards start at 4GB and go up to 32GB but, as stated earlier, will not work in the 4010.

tis logical that sumsung digimax 401 cannot procees a 2gb memory card, use 1 gb will format ok.

It could mean that you should format the card in the camera.

try formatting the card to see if it still errors. Even do it on a PC via a card reader tp eliminate possibility of a bad head on the camera

this is an older unit, when this unit was manufactured, 2gb memory cards were still unavailable. basically, 2 gb memory cards are not compatible with the unit, try to use a lower capacity memory card

you cant use 2gb sd card with this camera. check the guranteed media capacity for your camera. check your manual.

the samsung digimax 4010 camera supports up to 512 Mb cards. 2gb is too big

the maximum amount of memory for Samsung Digimax 401 (or 4010) is 512 Mb
