Hello -

I just want to add my experience with the MBR Write error I had with a ScanDisk Flash Drive.

I got the same error after formatting the drive three times. I had to make sure I had formatted it in FAT or FAT32. After formatting, I opened the drive to look at files and folders and found two folders still on the disk: Documents and System (hidden folder) which automatically get written to it. I also found an executable called LaunchU3.exe. When I deleted everything from the drive, including the .exe, I was able to install the program and it wrote the MBR with no issues.
