    I have the same problem with my Nikon D70. Did you get yours repaired?

  • Paul7925 Feb 22, 2009

    I'm having the same problem with my D70s, where cards I've used for awhile (Sandisk Extreme IV cards) are having problems, either with teh CHA code or a FOR code. I reformat the cards, but still have problems.



    Is this a software problem in the camera or a hardware problem with the camera?



    I've had the camera for 3 1/2 years and have taken about 25,000 pictures with it.

    I had the same problem with my D70 and was told I was looking at $300 to repair (not worth it) so I took it apart. If your mechanically inclined it is relatively easy.



    First (making certain the battery is removed) I took a micro file and lightly ran it on both sides of the CF pins taking care not to bend any... the hardest part... just be delicate.



    Second, I removed the bottom of the camera (8 small screws) and the back (2 small screws on each side). Carefully remove the connector for the back from the PCB on the bottom.



    Third, remove the connector for the CF socket, also on the bottom PCB and carefully roll it down into the enclosure. There are (2) small screw that hold the CF socket in (be careful not to loose the brass seperator plate behind the bracket).



    Finally inspect the back of the CF socket for and pins that may have been pushed out as a result of CF card insertion. Mine had (2)... I used a tweezer tip to push them back into place. Be certain to insure that they are straight in the socket and test a few times by slowly inserting a CF card.



    Now slowly reverse the assembly and test.



    The repair is about $300, the camera is worth about $300... if it's not working you have little to lose. Mine has been working for about a month now.

    I'm having the same issue on two of the cameras at the newspaper where I work. I might try skisup's suggestion on one of them.

    One solution that worked for me was to take out the Compact Flash Card and use a Q-tip with alcohol on it to get the alcohol into the contact point. Then I used canned air to dry the card contacts. I then pushed the Compact Flash in and out 5-6 times to clean the camera's contacts and POOF it worked. No more CHR or FOR to deal with. Also, I have a 32 gig compact flash and it is working just fine in the camera.

One of the pins in your slot is bent. I used a small screwdrive to straitened the pin and the camera works fine. It took me 4 minutes to resolve.

I have this problem and haven't had my Nikon for a year yet. Nikon needs to figure this out because when looking this up it seems to be a Nikon only problem.

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.

What does the error message CHA mean on a Nikon D70?


It means it can't read the memory card. Try formatting it. If that doesn't do it, try a different card.

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)

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.

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 have a Nikon D50 with an error message "CHA"


This error indicates the following:
This card cannot be used (CHR) blinks.
Problem(s)
Error accessing memory card
Unable to create a new folder (on card)
Card has not been formatted for use on D70

Try another card
Format the card using your D70 (all images will be erased)
Check the card for visible damage or poor contacts.

You may have inserted a memory card that was been used in a different camera or the formatting process did not complete successfully.
I hope this helps.

Nikon D70, displaying error code 'CHA' when memory card inserted. Unable to format or use memory card. Have tried new memory card, still same problem.


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.

Nikon D70 won't recognize the 2 GB, type II memory card


Try to clean the contacts of the memory cards and, mostly, of the memory card bay of the camera. Use a dry anti-static fabric (e.g. what we use to clean eye-glasses). DON'T use any liquid cleaner of anything like that!

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.
