First of all, this is a great site.
My PowerShot A70 has this tricky malfunction. When CF-card is inserted, my camera won't start. Without CF-card, it will start OK, though, it will report "no memory card".
So, the problem seems to be in CF-slot... Any homemade-idea, how could i fix this? Thanks in advance.

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.
Turn the power on.
Press the <MENU> button and select [ (Set up)] using or .
Select (Format) using or and press the <SET> button.
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.
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.
Take a look inside your camera's CF card slot. I suspect that you may have a bent pin in there. If so, don't fret. Although professional repair would be more costly than the value of the camera, there is a very good chance that you can repair this yourself. Please see this link,

Believe it or not, the camera's internal clock battery is worn down, causing this problem. Unfortunately, it's buried deep inside your camera, and is difficult to replace. But happily Canon will fix this problem for free. Please see this link.
Sorry, most Canon cameras do not have internal flash memory (maybe the newer models? But the A70 definitely does not). Those other model cameras that do have internal memory only have a few megabytes. And this memory is primarily intended only to take a couple pics to verify that the camera is working properly.
It isn't clear from your description, but are you inserting the reader into your USB port, and *then* inserting the CF into the reader? If so, try reversing this -- insert the CF into the reader, then insert the reader (with the CF) into a USB port. It is possible that your PC is only looking at the reader once (when it is inserted) and not finding a CF, then ignoring the CF once you insert it.
If your camera can read and write to the CF, then it is unlikely that the CF is damaged. Since you have determined that the reader is ok, and since your PC recognises the reader, it is unlikely that it is a USB driver problem. Similarly, it is unlikely that it is a physical problem with the USB port, or the pins in the reader or the CF card.
I dont know about formmating CF sandisk card with canon A70, however, i can recommend another method: hook it up to your desktop and format it through a CF adaptor. It may take a couple of attempts. it didnt do any damage, at least not one that im aware of. Im not 100% sure though, so don't get me responsible in case it will damage yours. anyways, if you do it, you can try the process described above.
