Re: CF card problem

Perform the following procedures if your camera does not detect a CF card. 1. Restart your camera. - Set the camera's power switch to and remove the batteries. - Open the CF card slot cover to make sure the CF card is securely set in the card slot. - Insert the batteries and turn the power switch . 2. Format a CF card. Format the CF card with your camera. Refer to the Camera User Guide supplied with your camera for instructions on formatting your card. 3. Check if your camera detects other CF cards (If you own multiple CF cards.) If your camera does not detect a CF card after performing the procedures 1 and 2 above, the card that wasn't detected may have a defect.

SOURCE: cannot detect cf card

You've certainly done the right things in narrowing the fault down so that's a great help.

Have a look down into the CF card slot, there should be two perfectly even rows of contact pins (two rows of twenty-five each). If any are bent (usually flat) or if there are gaps or obviously broken pins then you have found your fault. If so, the camera needs to go into an authorised Canon service centre to have the CF contact assembly replaced and you need to check your CF card to ensure that there are no broken pins left inside it (probably not as you've already used it in other cameras, but double-check anyway). Unbending a flattened pin usually breaks it off or just leaves it weakened sufficiently to break off in the near future; the broken pin can end up stuck in the CF card, and when you insert the card into another device the blocked hole bends or breaks the pin on the next device.

If there's no obvious damage then to completely eliminate the possibility of the CF card being faulty it's worth giving it a full format in either another Canon EOS model or via an external card reader (remember to back up any stored images first). If that fails, try to borrow another CF card to check whether that works in your camera. If not then the fault definitely lies with the camera.

At this point the only remaining option is a camera reset but it's unlikely to work. Your camera must be in the Creative Zone mode (P, Av, Tv, M, or A-Dep) to do this as all menus are then available. Go to "Clear Settings" in the camera menu, you'll see how to do this in the owner's manual. A word of caution: it's been a long while since I did this myself, so I don't recall whether this resets the camera image file numbering back to zero. If it does then every time you try to upload photos from the CF to your host pc there will be usually be messages warning you that the file(s) already exist(s). This means that you'll have to rename everything. To overcome this, you need to find a jpeg (picture) file, preferably one taken with your camera, and rename it to the number before where you want to restart from. So if you want the new files to start at IMG_2000, rename the file to IMG_1999). Then, using an external card reader drop the renamed jpeg file onto the CF card in the 100CANON folder (the number actual number may be anywhere from 100CANON up to 999CANON). Any further photos will be taken from the correct number onwards.

If all of the above options fail then your camera must be sent to an authorised Canon service centre for fault diagnosis and repair. If you're in the UK then click here for the UK service centres. Repairs will be free if your camera is still under the Canon warranty, but as it's only one year from the date of purchase it's likely to have expired on your 400D. The service centre will make a diagnosis and inform you of the likely repair costs; if you choose not to go ahead then the camera will be returned to you after you pay a small fee for postage and for the work already undertaken to investigate the fault.

Good luck with this and I hope that you soon have your camera working again. I hope that my reply has been of use and that you please spare a moment to rate my answer.

This is an old posting but I'd like to comment that once the memory card is used in a computer it won't read in the camera again until you format the memory card. Make sure you have all your pictures on the computer before formatting the memory card. A memory card must be formatted in the camera it is going to be used in.

Cf card problems


Take a look at the CF reader pins inside the camera - there could be a beant pin - happens quite often. If so, you can contact Canon or other camera repair shop and ask the price. If they ask too much, I can offer you a good price, if you're ready to send it to me. My e-mail is toms.safranovs@gmail.com

I took a picture wihtout a CF card in the camera


When you take pictures without the internal card , they get stored inside the camera internal memory (usually 8 or 16 MB only).

Connect the camera to a computer using a data cable, without putting any memory card inside the camera. The camera internal memory will be displayed as a new external usb disk on computer.

CF Card Err


Sounds like you have bent pins on your CF reader. Open the door, take out the card and look inside. Is there damage to the pins?

You maybe able to fix it with pincers and a needle just align the pin or pins that are out of place, i did this and it worked for me and now my camera is working fine. and for free.

Good luck

Error code 22


ERR 22: CF DRIVER
DESCRIPTION: This error occurs when image data cannot be written to the CF card. This error can occur when the CF card is not fully seated in the camera or if the D30 does not detect a card-ready signal within a specified time limit or when the CF card is not usable because it has been corrupted or physically damaged. It can also occur when the camera's battery level is insufficient to completely write the file to the CF card. REMEDIAL MEASURE: Use the DC Coupler or recharge the battery first. If the error continues to occur with sufficient power available to the camera, check that the CF card is properly inserted. If that's not the problem, then try replacing the CF card. If that does not solve the problem, have the EOS D30 and one of the CF cards that is causing the problem examined by a qualified service technician.
