Hello, I just remembered I've been meaning to mention this for awhile. When it comes to formatting a SDHC card, I format it inside my digital camera, not the PC. The reason is because for whatever reason, PC's don't format them properly which _may_ be related to possible issues. Also, the camera is fast.
Panasonic makes free SDHC formatter software for Windows
