I have an SanDisk Micro SD HC card tucked away and never used, I go to format it in my new 8900 and it formats the card,it says I have 7.63GB available, so I remove card to place in my computer and the computer doesn't see it, so I try my old 2GB card from my 8320, format from 8900 and insert into computer and it sees it. Is my 8gb card bad?
