That was the crucial point I was trying to determine, i.e., whether it was the source drive - the "old" SSD - or the destination drive - the "new" SSD - for the recipient of the cloned contents of the source drive. Since you've indicated it was the destination drive, i.e., the recipient of the clone that was the disk incorrectly converted to a Dynamic disk by your friend, and not the source disk, then it's an easy fix. Just repeat the disk-cloning operation to ensure the newly-cloned drive is also a Basic disk. ENSURE THAT THE NEWLY-CLONED "NEW" SSD IS NOT, REPEAT - NOT - A DYNAMIC DISK.
