Internal memory card reader not working

SOURCE: No memory card will work in my Coolpix camera

Nikon has tested the following cards and approved their use in the Coolpix 3200:

SD memory cards:
SanDisk 16/32/64/128/256MB
Panasonic 16/32/64/128/256/512
Toshiba 16/32/64/128/256MB

Other brands and capacities of cards may work, but Nikon cannot guarantee their operation. Check with the manufacturer of the third-party card for compatibility information. Nikon recommends keeping one of the approved cards available for troubleshooting.

Multi Media cards (MMC) are not recommended and should not be used.

Have you tried dell's website for any drivers. If there are, reinstall them and see if that fixes it.

Try updating you drivers for your digital media reader. Also check your dcos to see if the DMR will read a 2GB card

There is no big differece between the two. Both of those can work on your DELL memory card. Cheers!!
