Help! My D70s has started giving me a CHA error… Albert Ters, via Facebook

Chris says… The manual calls this a general memory card error, which could mean a problem accessing the card, the camera being unable to create new folder, or the card not being formatted correctly.

Firstly, check whether you get the same error with other cards. If you don’t, it suggests a problem with that particular card.

If the error happens with other cards, it’s likely the camera’s internal Compact Flash reader is at fault – its array of pins can become bent or corroded.

If you’re feeling brave, you could take a look inside your camera. This site has some very detailed instructions: http://bit.ly/D70srepair

We can’t take any responsibility for the outcome, but some users report the problem has been fixed by doing this.

Is your D70s showing a CHA error? It could be a problem with the memory card, or with the camera itself
