"Mine is ExtreMemory 4 GB class 6, I had to partition and format it several times under Linux before it works on the F200."
How do you partition a card? I'm making sure it's the GP2X before I send it back! When the card is in and the GP2X is connected to the PC via USB, I click on F: (the drive) and it says the card is not formatted, when I take the card out, the PC tells me to insert the card back in. hence, the card reader on the GP2X must be doing something! I've just read that anything over 4gb might lead to incompatibility issues. Maybe I should try a 4gb one?
Anyone know of anything I can do to the card before I send it back?
