The memory card is M2 1gb and it was working fine when I last used it. When I connected it to my laptop, I transferred some files and then I pulled the USB connector. When I connected it again, it cant read the memory card anymore. Then it says "would you like to format it?" So I formatted it after checking and pulling the mem card a few times. After formatting it, I thought it was fine but when I checked my phone, it cant detect the meoroy card, so does the lasptop. Why?
