Had a OMG what just happend moment this past Friday. The 1st partition of 4 of course being the workbench got the check sum error and not validated. .. after some fooling around it looked hopeless and it just didn't go away.
Lucky I still had the old hard drive to format and copy that partition back to the sd card. So a easier solution (less work) is to have a image of the micro sd card.
Question is, what would one use to do this to get a perfect back up image?
