My nikon d70 will not regonize the sd card and gives a format signal

The D70 uses CF (compact flash) cards - I hope you are simply misnaming the CF card. But, if you did use an SD card, it would explain how you could have bent a pin.

I understand that Nikon is moving away from CF cards because of the 'bent pin issue' as well as the limited capacity of the CF card.

So, first I would try a CF card (any size) in the reader. If it still doesn't work, then I think you might check with a camera repair shop. If it is a bent pin, they can fix or replace the card reader. Note that the D70 body can be replaced with an EX rated used body for under $90 at

Thus, I wouldn't pay $100 to have the reader fixed unless there are extenuating circumstances. Good luck.

CHA appears in window and camera will not work at all

The very first thing which you should try is another CF card. Preferably a brand new one (not Lexar 80x, see below), but if not then use one which has been freshly reformatted in another Nikon DSLR.

ziggy53 on the Digital Grin forum posted an answer to this question two years ago. As I cannot put it any more clearly or succinctly his posting is reproduced as follows:-

"It appears that a Nikon D70/D70s CHA error is a general "cannot writeto card" error and can be caused by many different situations including:

1) CF card fault/failure
2) CF card fragmentation
3) CF connection, camera contacts
4) Camera internal failure with card write circuit board
5) Power supply in camera, potentially also related to the battery.

To rule out the Compact Flash card(s) as the fault, try a brand newcard (not Lexar 80x, as those seem problematic), format in camera anddo not field erase images. Reformat card in camera to start over. Ifthis procedure works, format the older cards in the camera and thenwork the cards by taking images, preferably RAW to fill up the card asquickly as possible. Do not completely fill the card but stop at around10 remaining images and format the card in camera once more. You mightbe good to go.

If these procedures don't work, it is recommended to return the camerato Nikon for a checkup. If Nikon cannot diagnose a problem, you mighttry a new battery as some claim a weak battery to be part of theproblem, but I don't see that "cure" mentioned often enough to know ifreally is a cure or not.

Repairs for an out-of-warranty repair for the problem relating to thecamera seem to run around $300USD from those few folks who reported acost."

All credit to ziggy53

I've experienced this problem on a few D70 and D70s models and the advice ziggy53 gives has proven to be right on the mark; to Nikon's credit I've also found that in every case where I've definitely eliminated the possibility of a CF card failure they have attempted out of warranty repairs on a goodwill basis: all I had to pay for was for tracked and insured shipping to Nikon and they paid to return them. Of the five or six cameras which I've sent back so far only one had the problem re-emerge albeit in a less serious and very infrequent form. By then I'd given the camera to my niece and she's decided the fault is not serious enough to warrant sending it back again.

Do the Nikon D100 and the D70 share the same in camera Compact Flash unit - not cards - but the hardware to accept and read the CF card? I have a bent pin in the D70 and want to know if I can change out...

I understand what your're looking for.

The D100 is basically an N80 with digital guts. It doesn't share the same chassis as the D70, although it does share the same excellent battery.

Other than that, the D70 was a new design, so it doesn't seem too likely that they would have the same CF sockets.

That being said, unless I had them both stripped apart on the table in front of me, I wouldn't make any bets. It just seems like there would be slight differences in mounting holes and configuration.

I have a Nikon D70. Camera doesn't read CF.

Sometimes pins inside take strain.  Read up on how to replace the CF pin unit.  Not too difficult as long as you don't force anything and remember to retrieve the little metal strip....

I had the same problem and thought I had looked closely at the pins in CF slot but after finally taking it to a repair shop, the tech showed me a bent pin. It really wasn't that apparent first time around. He told me its a common problem as long as they use the CF cards. I had the pins replaced and my D100 is working great. Best of luck.

Problem with Nikon D70

The error code "CHA" is telling you that the CF card you are using for storage is not compatible with the camera. You should consider trying a different card, perhaps a slightly older one that is not as fast.

I use a SanDisk Ultra II card, and that works fine for me.
