SD Card not accessable

[Valkysas]

Hi,

I own a XDA3 with WindowsMobile2003SE; whenever i insert a SD Card the system recognizes the right amount of memory size (in my case 64MB (camera formated), 512MB) but when i try to make a new fodler or copy files it says something like "a device connected to the system does not work".
Theres no write protection enabled and i tried to format the 512MB Card with the shareware version of Resco Explorer 2005 - no success

can anyone please help me

thx in advice
