First card: Copying images files (Windows 7 Professional) breaks off with the error message that the "destination unknown" was - I did not understand, the map tries by reformatting reset as it were - nothing works (previously copied files can be do not even delete - card returned, requested replacement. Second card (replacement): came very quickly - but oh frustration, the same problem - so back, but this time I'm gonna look for a different card. (Incidentally, I have the same images files a few weeks ago copied the same operating system on the same computer for use on a Galaxy tablet to Samsung SD - without any problem ...)
