When i turn my camera on it says format set ok? so i press ok and it just says card error and wont let me press off it or wont let me get onto anything, how do i solve this?

I have the same camera with the same problem. You can try formatting the card using the camera. With the camera set as if you are going to look at what's on the card, press the Menu/OK button. Move up to the word Format, press Menu/OK button, FORMAT OK? should display. Press Menu/OK button. This will format your card. Unfortunately, I think there is something wrong with my camera. Still getting 'card not initialized'.

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.

Is the error message appearing on the caemra or the computer?

I will in both cases recommend to format the SD card and to update your firmware.

Format your SD card. NOTE this will delete all existing data on your SD card.
Do the following:

1. Insert the memory card into the camera. Make sure the card is firmly seated (push in the card until it clicks into place).
2. Turn on the camera.
3. Press the Menu button, then go to the Setup Menu.

Scroll up or down to the Format option, then press the OK button

Instructions to uploading new firmware:
Connect the camera with the computer.
Turn the camera on.
Click onto the link and follow the instructions.

If successful please give me the feedback as a rating or recommendation. Thank You

Your camera is only supporting SD/MMC Cards (up to 1GB)

The card that you currently have might be faulty. Please try another card.

You might also need to switch the camera over to saving pictures directly onto the SD card.1: Menu, Cam settings, Chose AUTO or SD card option Press OK
Note: If the SD card isn't in the camera or is unreadable the camera will automatically go back to saving you taken pictures on the internal memory.

You need to format a new card in the camera.

To format the card:
1 Pressing the Erase mode button and the Flash mode
button at the same time sets the screen to the YES/NO
display.
2 Press the OK button to start formatting (the Card error
indicator blinks). Press the Erase mode button to cancel
the mode.
3 When the card formatting is done, the Card error indicator
goes off.
To re-format the card intentionally:
Press the Erase mode button and the LCD monitor ON/OFF
button simultaneously, with the power OFF, to set to the Yes/No display and then press ok.

I had the same problem; formatted it on the computer; still the same. I the got this info (below) from tomshardware site and it worked for me:
1. Turn the camera on (to Photography Mode, not Playback Mode).

2. Press the Menu/OK button.

3. Move left or right until you reach the Option Menu.

4. Move up to SET-UP and press the Menu/OK button.

5. There are 4 option screens. The Format option is in screen
number 1, so you should see it immediately.

6. Move down to Format and then either move right or press Menu/OK.

Format the card in the Camera- read your manual
