After inserting cf card into canon s30 i get cf

Oh dear. Why are you wiping the IPL? You are seriously screwing up the firmware in the machine. It might be best to see a dealer to have them change IPLs for you

Issue: Memory card Error
Solution: Try a different memory card and/or Reformat memory card PowerShot A70


Formatting a CF Card You should always format a new CF card or one from which you wish to erase all images and other data.
Please note that formatting a CF card erases all data, including protected images and other file types. Please check the contents of the CF card before formatting it.

1. Turn the power on.
   
   
2. Press the <MENU> button and select [ (Set up)] using or .
   
   
   
   
3. Select (Format) using or and press the <SET> button.
   
   
   
   
4. Select [OK] using or and press the <SET> button.
   
   
   
   
   • To cancel formatting instead, select [Cancel] and press the <SET> button.
   • The capacity of the CF card displayed after formatting will be less than the rated capacity of the CF card. This is not a malfunction of the CF card or camera.
   
   
   
5. Press the <MENU> button.

• If the camera does not work properly, the inserted CF card may be malfunctioning. Reformatting the CF card may solve the problem.
• When a non-Canon brand CF card is malfunctioning, reformatting it may solve the problem.
• CF cards formatted in another camera, computer or peripheral device may not operate correctly. When that happens, reformat the CF card with this camera.

Hello :

Here is what Canon said according some forums :

To isolate the cause of the issue, we suggest that you 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 a fully charged battery, and turn on the camera.

Does the "ERR 99" message appear? If it does, then the camera should
be serviced. If it does not, then please proceed to the next set of
steps:

1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.

Does the "ERR 99" message appear? If so, then the CF card is the most likely source of the issue. Try using a different card.

If the message does not appear, please complete the following steps:

1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.

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 should be serviced.
I hope this will help .

please don't forget to rate !

You need to format new cards in the camera before using.

error 99 can most times be remedied by taking a standard pencil eraser and carefully cleaning the gold contacts at the back of the lens and the gold maching contacts in the lens opening of the camera... BE CAREFUL not to let eraser crumbs into your camera... keep it clean... reset the battery and give it a whirl.... did it solve the 99 issue?
for the CF it refers to the cf card... here's what I've found on this:
Canon reports that this error code may appear on your digital camera’s LCD (liquid-crystal display) when there is an error reading from or writing to the inserted CF (CompactFlash) card. This error code occurs most often after a user has tried to eject a CF card before the camera has finished writing data to the card.Solution:
Canon suggests that you first try to use a different CF card. If you do not see the error message when you use the new CF card, the first card is probably damaged.

Before you take the next step, drag the files from the CF card to a location on your hard drive to back up the files. Next, you can use Windows’ ScanDisk utility to check the CF card for errors. If you use a Mac, you can use Disk Utility (in Applications\Utilities\) in OS X.

If ScanDisk or Disk Utility fails to resolve the CF card problem, insert the CF card in your camera again. Then format the CF card. On most Canon cameras, you can do this by pressing the Menu button, selecting the Format tab, highlighting Format, selecting Format, and choosing Yes. Make sure you have backed up the data on the card before you do this. Formatting the card will delete the images from the card. After you format the card in your camera, use ScanDisk or Disk Utility to check the CF card again. If you still encounter errors while using ScanDisk or Disk Utility, you should discard the CF card because it is damaged.

If the error still occurs after following the steps above, your camera may need repair. Contact Canon’s technical support for further assistance.

hope this solves your issues....
let me know

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.

Error 99 can mean many things. Have you installed the latest firmware for the camera (version 1.1.1)? If you don't have, download it here (for equipment purchased in USA or Puerto Rico):

http://web.canon.jp/imaging/eosd/eos40d/eos40d-firmware-e.html

If you have the latest firmware, try this:

1. Switch off the camera and remove the CF card and battery
2. Keep the camera idle for 30 min
3. Clean all the contacts of the camera (battery contacts, lens contacts etc) with an eraser. Do this keeping the camera facing down so that no debris fall into the camera.
4. Attach the lens and insert the battery.
5. Switch on the camera
6. Insert the CF card
7. If the error persists, format the card again
8. If this does not work, try using another CF card.
   

According to Canon, Error code 02 means that "There is a problem with the CF card. Try any of the following: Remove and re-insert the CF card. Format the CF card, use a different CF card."

Are both CF cards the same brand? Sometimes some brands have conflicts with the camera, you might try using two different brands.

It may not be the card, did you try on the third attempt to remove the battery and put it back in? There may be a problem with the contact points where the CF card plugs into the camera, or in the transfer system itself.

Error Code "E50" (CF card formatting error) When a camera error occurs, an error code like "Exx" will be displayed, where the x's represent numbers. The "E50" error code indicates formatting a CF card has failed. Solution To clear the "E50" error, try performing the following procedure. 1. Try using another CF card. If you have another CF card, try loading it in the camera. If the error code is not displayed when the other CF card is loaded, there may be something wrong with the first one rather than with the camera. 2. Use your computer's ScanDisk utility to check the CF card for errors. Use ScanDisk to check the CF card for card error or card failure. Refer to the instruction manual for your operating system or Windows Help for further instructions. (If you are using a Macintosh, use the "Disk First Aid" program to check for card error or card failure. Refer to the instruction manual for your Macintosh OS for further information.) Be sure to back up the data on the CF card on the computer before you check the CF card. If a card error or card failure occurs when you use your computer's ScanDisk, there is something wrong with the CF card. Follow ScanDisk's on-screen instructions to solve the problem. If the same error occurs when you are using the CF card supplied with the camera, please contact the retailer where you purchased the camera or the nearest Canon service center. If the error code is displayed right after you took a picture, the image may not have been recorded. Switch the camera to playback mode to check if it was recorded. 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.
