4 GB microSDHC problem

I was given a 4 GB microSDHC for my camera, I have a canon powershot S2 IS and it says memory card error. I dont know what to do. Please help

You could try formatting it.

Your camera model **canon powershot S2 IS** supports only SD cards ie. upto 2GB.

and anything higher than 2 is an SDHC cards and is not supported by ur camera.
