Ok, first post. I have a 2GB MSDuo Sony (not Sandisk) card of which I am forced to reformat everytime I want to add a new file to it, whether that's via the USB Mode on the PSP or via an external card reader. Everytime I don't do that move, the file always ends up corrupted.
Any tips as to minimise the problem? Or should I just give up and wait for a less flaky 4GB card? Cheers.
