I have an Axim X30 and want to reformat my SD card (I think my digital camera corrupted it). How do I format it? I see how I can delete files manually, but I want to do a true reformat. I don't have an SD card reader, I need to know how to do it from the Axim itself. Do I need to download the Pocket Mechanic trial as suggested in another post, or is there a simple way to do this with the operating system built into the Axim? Thanks!
