The card slot is on the right end of the camera (as viewed from the back). Follow the illustrated instructions on page 20 of the manual.

No. SDHC cards won't work in devices not designed for them. You need to use SD cards, 2GB and smaller.

This is the manual for it: http://software.canon-europe.com/software/0029207.asp?model=
The web site shows that this camera does not need drivers but they offer an application that works with the camera http://www.usa.canon.com/cusa/support/consumer/digital_cameras/powershot_a_series/powershot_a460?selectedName=Specifications#DriversAndSoftware Select - "ZoomBrowser EX 6.6.0b application"

The Canon A430 uses MMC and SD cards. While SDHC cards will fit into the slot they are electronically incompatible and will not work. You need to use SD cards, 2GB and smaller.

powershoot SX120 IS was dropped on cement. Now on/off button doesn't work. Is there a remedy?

Tend to agree with you that it's a common design problem for the A430, but it's a very different issue than CCD failure mentioned in you referenced article.

Please see this Fixya post instead of the one that you mention above. Unfortunately, Canon has yet to officially recognize this A430 specific problem. But if you reference this Fixya post, (include a link), when contacting Canon (if in US, email is [email protected]. You'll have to research www.canon.com to find an equivalent UK email contact), who knows you might get lucky

Forget all that...use a card reader to download your pics.

Below is a link to the download page containing user manuals for your Canon A430 free of charge.
