My Lumix DMC ZS7 reads "insert sd card again" when I have a full sd card inserted. The sd card is "verbatim sdhc 4gb" any idea? Thanks in advance

Yes format the memory card. Go into the camera's Menu and select Foemat memory card.

There are recovery programs available. Google SDHC data recovery.

Insert the card. Go into the camera menu and find "format" and follow the on-screen instructions.

There are no SD memory cards 4GB or larger because the Secure Digital standard limits card capacities to 2GB. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in the DMC-FZ30. You will need to stay with SD cards 2GB and smaller.

Take the card back if you can....your camera can only use SD cards...not SDHC.

The mode dial on the top of the camera is set to clipboard. Turn the dial to P or iA.

There are no 4GB SD cards. "SD" cards larger than about 2GB are actually SDHC cards. SD and SDHC cards fit the same slots, but they are slightly different electrically. Many cameras won't work with SDHC (high capacity) cards. SDHC is not backwards compatible.

A card that size is actually an SDHC card. SD and SDHC cards fit the same slots, but they are slightly different. Many cameras won't work with the SDHC (high capacity) cards. SDHC is not backwards compatible.

I expect your camera just won't work with this kind of card. It is often difficult to find out the maximum capacity memory card a camera will use, as today's cards are much larger that those available when the manual for the camera was written.

Check your instructions, is a 4GB SDHC card compatible with your camera.

if you don't have a manual, just google "panasonic lumix dmc-fx01 manual" several options will appear.

Page 16 deals with card compatibility, it states that the maximum you can use is a 2GB Sd card, no mention of SDHC.

The card needs to be formatted in the camera to work properly.
