I have seen compatibility issues with some SDHC cards, especially older versions. They will work in some devices but not others. The fact that yours doesn't work in two different devices virtually guarantees that it has those issues. Typically there is nothing you can do to make it work. Rather than mess with it, I think I would just buy another one. Newegg has several for around $15, and 8g for around $20. Look for ones with free shipping.
