Not too much info on the card, as it isn't mine. But it is a 16 gig Samsung Class 2 MicroSDHC card. Previously used in an AT&T Samsung Android phone (has big touch screen... don't know model). Anyway, card has somehow become write protected. Obviously, since it is a MicroSD, there is no lock switch. Data can be read from the card, but nothing can be written to it nor can it be formatted, either from Windows, the Panasonic SD Formatter, or my other Samsung phone (Samsung Reality). How on Earth does this happen??? Can anyone give insight on how to fix it?
