I keep coming back to G4U. First used it for production to create Reiser file system clones of disks from images on server. Sometimes using Ghost(tm), it failed to copy boot records (laptop upgrades), so I used G4U, and it worked. Now I am using it again to create Linux systems on SD cards. It was actually faster using an FTP server image than local disk to disk (tested that on first project). I just booted on CD and had operator type single command line to create a new disk. Since it's block by block copy, it seems to copy anything.
Easy to use and works.
Reliable and runs smoothly
Fast and simple.
Incredible structure and very perfectly created.
