I bought a 32gb microSDHC card from costco. It came with a little adaptor, but I had a usb adaptor that I was able to use. I was able to copy files to it without any issues and moved some files from my desktop to my laptop. I double checked that the included adaptor worked and the files saved and copied just fine using it. I then mailed both items to a friend. When my friend got it, it claims it requires formatting.
Does anybody have any idea why it’s doing that? They have tried a couple of computers and even a usb adaptor that they own. We’re both using win 7.
