I was wondering what this adata type usb is for. I stole it thinking it was a memory but when I got home I noticed it had two types of heads. The regular USB and the mini usb commonly used to for cell phones. When I plug it in it has its drivers the pc reads it but theres nothing there. Like it doesnt have a memory. I thought about returning but then I figured first I want to find out whats it for. It has me wondering. I thought about formatting it but I cant. I then thought it was for charging batteries or something. It could just be a memory but just that its damaged. I noticed it also doesnt have its memory size on display like they usually do.
