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.
Sccording to my D70 manual:
"CHA"= this card cannot be used. try Nikon approved card,, Try reformatting card in camera, not PC, clean card contacts in camera using camel hair brush and blower.
You might also use a small pen and press the hardware rest buttin in bottom of camera (page 200 in manual)
SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.
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.
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.
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.
CHA errors indicate a communication issue with the CF card. Your card
could be going bad, you could have a broken pin, or any number of other
problems.
I'm
running into this same problem now. If anyone has a good step-by-step
to troubleshoot which of the dozen things this error could be, I'd
appreciate it.
For myself, I'm planning to start by trying a new CF card.
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.
Do you have a memory card in the camera? What happens with a different card?
