Nikon D90 and memory card counter

usually, you push the card in harder and it springs out by its self

This indicates the lack of a memory card, or else the installed card is faulty. Remove the memory card (if present), put in a new one, and format it.

The CRH error message means that the lock tab on your memory card is in the locked position. The purpose for the lock switch is to allow you to set your SD card so that you cannot accidently erase your valuable pictures. Remove your SD flash memory card from the camera and hold it in your hand with the label toward you and the angled corner to the upper right. Look on the left edge of the card and you will see a very small slider switch. Make sure the switch is in the fully up position then reinsert it in the D90. If the camera is not generating a false error, your camera should work correctly.

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.

Format the memory card. Press and hold the two [FORMAT] buttons until "For" blinks on the top display. Release the two buttons and then press the same two buttons again.

Having received no response in over a month, I assume the suggested cleaning solved the problem.

SD card memory is located in ur SD card and Sim Card memory is in the Sim card.

U will have to delet some of ur messeges on the regular basis to keep ur sim free to accept new messeges. if u dont do that then ur new messeges will never reach u and will keep bouncing back to the sender. U can always copy some of ur important messeges in to ur phone memory or sim memory in order to keep ur sim free with some space.

Hope this resolves ur prob.

thanks

The E in the ISO field simply indicates that there is no memory card installed. This is not an error, as you stated that you haven't inserted a memory card. Put in the memory card and format it, and this will go away.

Is there a memory card in the camera?

Also try cleaning the contacts on the lens (light rub with a pencil eraser works).

Hi,
It is meant to.
The D90 always shows this even when off.

It explains it on page 35 of my manual.
Camera Off Display
If the camera is turned off with a battery and memory card inserted, the number of exposures remaining will be displayed.
