Not sure this is really a D3100 issue so much as a memory card issue (likely corrupt), but posting here for any wisdom you all might be able to share. I was shooting today at a family outing when all of a sudden I got this error "This Memory Card Cannot Be Used. It may be damaged. Use another card". That may not be the exact text, but it was something VERY similar and I'm sure the first sentence is correct.
Anyway - another, identical SD card works just fine, but this one cannot be read any longer by the camera or any of my various SD cards readers (one built into my printer, one built into my laptop..both which can read other SD cards just find, including others that are identical in maker and specs to this one).
Tried to recover the data on it, but none of the software I downloaded can even get tot he point of recovery because none of the readers are even able to recognize the card.

I use SanDisk Image Rescue, not sure what you've tried, but it's got a pretty good recovery rate for me - high 80s percentile.
As far as the card is concerned, it's time to take it out of circulation. You can try to reformat it in the camera, but once it's failed, you don't want to take a chance on it, especially with images that are irreplaceable in any sense. Given the relative low cost of SDs on the market, just replace it at this point and chalk it up to operating costs.

Any thoughts on what to do if nothing seems to want to recognize the card? My camera (oddly, regardless of whether the power is on or off)displays and freezes on this error. I cannot interact at all with the camera once this card is inserted. When a new one is inserted, everything returns to normal.
Same with my card readers - one (on my printer) returns a similar error and refuses to recognize the card. On my laptop, the SD reader simply never appears as a valid drive when this particular card is inserted.
I assume I have to find a device that will actually recognize the card before I attempt to use SanDisk Image Rescue to try to get the files off of it, correct?
Finally - anyone know if there's a two-button reformat options on the D3100 similar to that which exists on higher-end cams like my D300?

Ugh - that sounds like a really nasty error. If it's freezing the camera upon start-up, that's usually an indication that it can't even read the card as being a valid format - layman's speak, it's really hosed.
Not sure what your options are to recover the images. If the card isn't readable on camera or PC, that's the first obstacle to overcome.
When it's in a PC card reader, do you at least get the option to format the card?
As for the recovery of the images:
This is at your own risk - consider formatting it in the PC (assuming it can be done) to make it a readable card again, then seeing what the recovery software can get out of it.
The only other option is to send it off *as is* to a Commercial Recovery Service and seeing what they can find.

What is the brand of the card? If its a Transcend card that could be your problem. We got a Transcend (16gb "so called class 10") SD card with the D3100 we bought from Amazon last January. Before buying more Transcend cards I did a search to find out more about Transcend and what I found out was pretty awful.
One of the people blogging about their problems with that card had bought a bunch of them because he was going on "a once in a life time trip around the world". His Transcend cards started failing half way through his trip. Since he had "once in a lifetime" photos on them he paid a data recovery service big bucks to recover "most" of his photos - regular data recovery software didn't work.
Also I trust that you are reformatting your cards in the camera, letting your computer reformat can cause problems too. But from what you are saying I'm reminded of the horror stories I read from folks who had bad experiences with Transcend memory cards.
"Humans don't rise to the occasion. Instead, we fall to our level of training and experience". Archilochus, a Greek soldier and poet. The best photo advice I ever received was at a John Shaw workshop. "... Practice your craft... ... Pixels are free...Practice... experiment with your camera".

No, it's not a Transcend card (with which I have actually had good experience in he past). It's a PNY card (whatever that is). I'm pretty sure it's a cheap, drugstore brand card. The d3100 is my wife's cam she got a couple years ago with two of these cards, both 8gb each. I've always known that I should replace them, but we don't use her camera enough to think about doing it (I use a D300, mostly, and so new SD cards aren't usually on my radar).
Thankfully, the pictures aren't of a once in a lifetime experience. They are memorable, for sure, but not critical. I'll hang onto the card to see if I can ever manage to find a way to recover the shots economically, but I'm definitely going to buy a couple of new SanDisk SD cards very soon.

Your right PNY (pronounced Penny) is a discount brand, the also make system RAM.
They are mostly sold at places such as Staples, OfficeMax and Office Depot (office supplies).
Never have felt they were reputable.
SanDisk, or Kodak , Transcend all good brands.
I would get pictures of of those PNY cards ASP, and get some SanDisk or Transcend cards and transfer to them if its even possible. OR dump the picture on to your computer for safekeeping and start new.
