Looking around, I do not find a definition for exactly what this means, only suggestions like remove the battery and memory card and reseat them to make it go away, but many say it returns later. What exactly does CHA mean and how should one resolve it more definitively? battery nikon-d90 memory-card error share|improve

this question asked Oct 1 '13 at 23:37 WilliamKF 80031432 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted The D90 uses CHA as a generic 'card error' condition if a problem occurs while the card is in use. If the card works at all or has been working then it's unlikely to be a formatting issue. This could just be a case of a poor connection and cleaning the contacts on the card and reseating everything may solve it. If it has been working then there could be a problem with the card in which case you should be able to test it in a desktop machine and retire/replace it if necessary. There is also an issue I've had with the D90 and larger memory cards (over 8gb) where it incorrectly calculates 'checksums' used to determine if there is a problem (although it writes them correctly) when the value isn't what it expects then you'll get a CHA message. As a temporary resolution you can access the card in a reader and copy & remove the last written file but if this is your issue then the problem will return at some point. I've been in touch with Nikon about it but without being able to reproduce the issue at will Nikon have not been helpful. The solution I ended up with was just to use multiple cards, which is no great hardship. share|improve this answer answered Oct 2 '13 at 11:59 James Snell 7,4551330 add a comm

Nikon D70 Cha Error Fix
Answers (ex. how to reset a sansa player) SD/SDHC/SDXC memory card nikon error codes is write protected or locked Why do I get a "The disk is write-protected" message when I transfer files to my SDcard? SOLUTION 1 - Unlock the memory card. There is a Lock switch on the left side of the SD card. Make sure the Lock switch http://photo.stackexchange.com/questions/43094/what-does-cha-mean-on-nikon-d-90 is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked. SOLUTION 2 - Toggle the lock switch. If the lock switch is loose and moves easily It is likely the switch is sliding to the locked position as the card is placed in your host device. http://kb.sandisk.com/app/answers/detail/a_id/1102/~/sd%2Fsdhc%2Fsdxc-memory-card-is-write-protected-or-locked In this case the card will need to be replaced.

prevent the memory card from being erased or wiped. Not all types of memory cards will feature these; SD and Memory Sticks often include the write protect switch. Step 1: Check the Switch SD Cards have a physical switch on the side of them which sets the write protection of the card. If the write protect switch is in the locked position, then it will not be possible to write to the card. It will, however, be possible to read the photographs from the card if they are already there. Mini and Micro SD cards do not feature a switch, however, when they are placed in the SD card adaptor to fit into your computer, there is a lock switch. Some people mistakenly believe that this is to lock the card in position, however, this is actually a write protect switch. When using the adapter, you shouldn't touch the switch. Step 2: Repair the Switch Sometimes the switch can break off the memory card, which will leave the card in a locked position. This will mean that you won't be able to unlock the card because there's no switch. If this is the case, then it's fairly easy torepair the switch. The switch itself does not do anything inside the card; it is simply a piece of plastic which hits a switch inside the camera or reader. This means that it works in exactly the same way as the switch on an old 3.5" floppy disk, or the tabs on a VHS tape. Repair the switch by simply sticking a piece of tape over the correct section of the switch. Once this is fixed in place, the switch will be depressed correctly. This will mean that the switch is no longer write protected and it will be possible to write photos to it once again. Step 3: Remove Protection It's also possible to protect individual files on your camera's memory card by selecting an option in your camera's menus. This protection will need to be removed before the individual files can be removed or adjusted. If you're not sure how to do this, look through the
