I have an Android HTC phone. It has a micro SD card. I want to make an EXACT duplicate of the contents to see if my new faster card will perform better. How do I go about making an exact duplicate? My first thought was to copy every folder onto a single folder on my pc then write it back to the new card. However, I am not sure if there is a particular structure or formatting needed for the HTC. Secondary question: Should I first format it with the phone or the pc? FAT or NTFS?
