"card error" removed the cf card to place pics on my computer...put the cf card back in the camera and the screen reads card error...bought a new cf card and a new xd card and when i placed the new cards in camera still received "card error" with both...

Do both of these CF cards still function when you connect them to the computer?
Inspect the CF connector on the camera using a flashlight (torch). It's possible that one or more pins on the connector may have been damaged, somehow. If this is the case, the camera will need to be repaired.
Can you still operate the menus after the error message appears? If so, use the menus to reformat the card (see the manual for instructions).

Nope, this is not card anymore.

As you know CF is card failure, sometimes this cause to start error 99 , that is lens error , even if there is no problem with the lens.

This happens because the built in software in the camera can get messed up after an error CF.

You fix the problem calling Canon, they will guide through upgrading the firmware in your camera.

First ensure that you are using the camera menu and command to format the new card, and that new cards are properly inserted into the machine.

Call Canon support to get a firmware upgrade.

Not all CF cards are created equally, so yes, it could be your batch of cards. To determine if the error is CF related, and not anything else, try the following steps which are used to diagnose err 99's

To isolate the cause of the issue, do the following: -

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert only a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.


Does the “ERR 99′ message appear? If so, the camera may be faulty and requires a service. If it does not, then: -

1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.


Does the “ERR 99′ message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -

1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the camera is faulty and should be serviced.

You can put max 1GB cf card.

Buy a camera that does not use CF. Time to upgrade.

It sounds like your Dazzle is not compatible with the sandisk. Maybe the Sandisk CF UltraII card have a new update software in it.

a virus is present in your pc, infecting the memory card. I suggest that whenever your card leaves the camera and used in any computer or lab, always format the card in your camera not in pc cause this will gonna erase all the pictures including the virus. virus in cf cards wont destroy your camera but it will make it operates like crazy. Make it a standard operating procedure to always format card inside the camera.
Photolab will be able to read even a corrupted card.

This is a just a thought but some of the better CF cards have a small generally white switch on them. When it is flipped you can not write to or erase of format the cards. If you have the switch try flpping it and see if this changes anything.

Precautions for handling a CF card: - Do not remove a CF card or disconnect the camera's power source while the camera is recording, loading, or erasing data on a CF card. - CF cards are high-precision electronic devices. Do not bend, force, or subject them to shocks or vibration. - Do not attempt to disassemble or alter a CF card. - Place the CF card in the supplied case for storage. - Moving a CF card rapidly between temperature extremes may cause condensation in the card, leading to potential malfunctions. To avoid condensation, place the CF card in a sealed plastic bag before moving it into a different temperature area and allow it to adjust slowly to the new temperature. If condensation forms on the CF card, put it aside until the water droplets have evaporated completely. - Do not use or store CF cards in the locations subject to dust or sand, high humidity, or high temperatures.
