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."

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.

If above solution doesn't work, it gets more complicated, but definitely fixable:

Why does new memory card displays CHA?


The "CHA" means the camera cannot read the card here are a couple of reasons why this may occur. The most probable is that the card didn't seat properly when you put it in so try reseating it.
CHA can also mean that the camera has detected an invalid partition type. Reformatting the card may allow it to be used.

Exposure button no longer working.


When you insert the card and get the CHA Flashing error, remove the card and format it. Reinsert it again.
Should work.

Also, if it doesn't work, there is a strong possibility there's a broken or bent pin in the memory card section of your camera. Just look closely and inspect that section to see if there's a broken or a bent pin.
This happens when you forcibly insert the card the wrong way. This has happened to a lot of users.

What does CHA mean


Nikon says this about CHA:


When a Memory card is inserted into a D-SLR camera, the camera checks the card for compatibility and usability. There are three possible results of the test:

1) Camera detects valid Memory card, displays number of remaining images in top LCD

2) Camera displays "FOR" in top control panel LCD. The camera has detected a valid disk partition map, but was unable to read the first sector of the Memory Card. Formatting the memory Card using the cameras format option, should resolve this condition and allow the Memory card to be used.

3) Camera displays "CHA" in top LCD. The camera has detected an invalid partition type or is not working properly. Reformatting the memory card may allow it to be used. If an approved memory card causes the camera to display the "CHA" indicator contact the memory cards manufacturer for assistance.

(Nikon's list of "approved" memory cards can be found here.)

Please note that the default disk format used in Windows XP is FAT32 and if a card is formatted with this setting on an XP system, a D1 series camera will report "CHA". Reformat the card as "FAT" to use in the D1 series camera.


When the CHA error is shown, typically the camera will freeze and require that the battery be removed from the camera before it can take another picture. After that picture has been taken, the camera freezes up again for many owners.

Some owners have success removing and either re-seating or inserting a new memory card in the camera.

Some owners have success clearing the error by removing the lens and then reinstalling.

The key to these "fixes" is that they don't all work for everyone. You might need to return the camera to Nikon for repair. You can arrange for Nikon service here.

I hope this helps and good luck. Please rate this reply
. Thank you.

Took the memory card out of my camera yesterday. when i put it back in it displays CHA on the screen. what happened? i can't use my camera.


The CHA error indicates an issue with the memory card in the camera.

Try another card and see if that works ok.

Also, always format cards in the camera.


In case the error comes back on a new card, you will need to send the camera to Nikon.

I will appreciate your feedback and positive rating for this free solution.

CHA?


I found this answer on the Nikon web site.

3) Camera displays “CHA” in top LCD. The camera has detected an invalid partition type or is not working properly. Reformatting the memory card may allow it to be used. If an approved memory card causes the camera to display the "CHA" indicator contact the memory cards manufacturer for assistance.

NIKON D100 LCD DISPLAY FLASHING CHA ERROR WITH ANY CF 1 GIG


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.

My D100 will not accept CF cards


You can always try the reset button. It is under the flap where the USB/Video out/ and power connector is. It is just above the power connector.

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.
