JA: Just to clarify, what's the exact make and model of your machine?
Customer: Nikon D70
JA: What happened right before this popped up? What troubleshooting have you tried?
Customer: I had old memory card in camera and was working fine. But when I try to format new memory card, the error appears.
JA: Anything else you want the camera expert to know before I connect you?
Customer: I'm certain the new memory card is the same as old. And when I put the old memory card in camera, everything works fine. I just can't format a new card.

Hi, thank you for contacting My name is Russell. I will do my best to provide

the right answer to your question.

Check whether the LOCK switch on the new memory card is in the right position. To re-format, it should be in the position opposite to the position the arrow next to the LOCK switch points.

If that isn't it, then it is possible that your new memory card is defective.

Is its capacity the same as the capacity of the previous memory card that does work?

And, what is the exact error message when it fails to reformat? 'CHR HELP' ? or 'CHR' ?

Customer: replied 9 months ago.
Error message is CHR I don't see any lock switch. Don't know what that is.
Customer: replied 9 months ago.
Is the lock switch on the card or camera?
Customer: replied 9 months ago.
When I place the memory card in camera, a green light comes on for a second. Same as it does with old memory card.
Customer: replied 9 months ago.
Previously I tried a new memory card, same brand but larger memory. Same error message. Returned it and bought a memory card exactly like my old one which still works.
Customer: replied 9 months ago.
Are you there?
Expert:  Russell H. replied 9 months ago.

The lock switch is on the card.

I'm here (I apologize, I was taking care of another customer for a bit.)

Expert:  Russell H. replied 9 months ago.

Verify, please: does the old memory card now work?

And, also: Do you have a computer with a memory card reader on it, please?

Customer: replied 9 months ago.
I don't see anything. I'm comparing it to the old card and I don't see a difference.
Expert:  Russell H. replied 9 months ago.

Does the old memory card still work, or when did it last work, please?

That the larger new memory card did not work is understandable. Memory card slots on cameras have a limit, or upper capacity size, to the cards they can use.

the old memory card still works.
Expert:  Russell H. replied 9 months ago.

Good. Then I would surmise that you simply have bought a defective memory card.

I advise you to take it back to the store or vendor you bought it from, and ask or an exchange for a fully working new card of the same type and size. Or, ask for a refund.

It is well to do this, as soon as possible, before the period of return and exchange or refund expires. Generally stores offer only a week or so for this.

Does this answer your question in full?

Ok. I will return this card and try another new one. I have two old memory card that still work. Since they are about ten years old, I thought that I should replace them. Does memory card have a life?
Expert:  Russell H. replied 9 months ago.

Memory cards and flash/USB drives are very sturdy.

If they start to not work, they are defective or 'broken'... for whatever reason.

But sheer age... if you have treated them well, etc.... should not be a problem. There is theoretically not much in the way of a maximum lifetime for memory cards.

But! for older memory cards, they are more likely to fail, so photos taken onto them should not be stored on them for long, lest you lose them through the card's sudden failure.

OK. Thanks.

Very good. Please rate my answer and my work and the information I have provided, so that this case may be closed. A five-star rating would be appreciated!
