Formatting Flash Card

Anyone having issues with their flash card? I've so far I tried the Kingston 2GB and the Sandisk II 2 GB also and am having issues with it being recognized on my pc and the MPC. It recognized it once. (with the card being inserted in the MPC. It won't recognize it in the PC's flash card reader which is in perfect condition) and when the was card is reinserted, I'm messaged that it's needs to be formatted again perfect. I checked the card reader to make sure the pins weren't bent and they are perfect. Any suggestions would be appreciated.

I also purchased a 512mb CF card and still no luck. Any suggestions?

Whatsup my man,i have the same problem, but whatb i did was buy a compact flash reader, and loaded all my sounds on it an then load it to my mpc. there is more than one way to skin a kat. Holla!!
