I try to open my 8gb micro sandisk card using the adapter on my computer. When I click to open it - it just takes forever and then I get the I/O error. The memory card is for my phone and I was trying to transfer some usic and pics on to it from an older memory card. I have no problem with smaller cards - like a 512mb, a 1gb or a 2gb. It just seems the 8gb is giving me problems. I just want to open it up in my computer. Is my computer not able to handle it possibly?
