Hi

Firstly, Im a complete beginner with androids so please excuse me if I ask basic questions
I recently purchased a Samsung Galaxy i5800
I managed to root the phone, and updated the firmware on it to I5800XXJPM Froyo
The phone seems to be working fine, but when I plug it into the PC, the MicroSD comes up in My Computer, but the icon is semi transparent
And when I try open it, it says insert disk
Anybody know what the issue could be?
Any help would be appreciated

Thanks
