Samsung 4010 camera wont accept a 4g sd card

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.

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.

That is correct. While SDHC cards will fit into SD slots, they are electronically incompatible. SD cards will work in SDHC slots but not the other way around. You need to go with SD cards 2GB and smaller.

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

make sure there isn't a limit on the memory size for the camera, some models have a limit.
also make sure the lock switch on the memory card isn't in the locked position: http://kb.sandisk.com/app/answers/detail/a_id/1102

Should the green LED flash continiously - there are still life left in the camera. Insert an external SD memory card in the battery compartment and the camera might power on. Seems the internal memory of 16MB is faulty....

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

batteries are dead,or not in properly.if not. only use energizer lithium batteries.others burn out very fast,hope i was helpful.

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

Reformat card - have you tried? Check your manual seek help in Samsung Web site Come back if still int rouble
