Hello! SD Card in my phone (GT540 upgraded to 2.1) doesn't work properly lately. For example, when I'm trying to put music on it from my computer it says "the directory cannot be created". In the same way when I want to create a logbook in OnTrack application it says the same thing. It seems like the card is locked somehow and I can't access it. It wasn't like that before 2 months when I bought the phone and in the meantime I didn't do anything to the phone what could cause problems. Does anybody know what could be the solution? Thanks!
