  1. G4L will also do an exact bit-by-bit clone as long as the destination drive is at least as big as the drive to be cloned. I tried cloning a boot hard drive with Clonezilla years ago when I was working on somebody’s Windows computer, but when I installed it, it wouldn’t boot. I looked for something else, found G4L and it has always worked perfectly. After starting again with G4L, the clone of the original drive booted fine.

  3. Hi, I am a newbie, but have had a Ubuntu 14.04 install on a laptop for

    I do NOT want to have to try and set the whole thing up again, that was four years ago I don’t remember anything about it. I can’t get any of this to work. All I get is error messages in terminal PLS.

    There has to be a way to do this. I have a new Dell gaming laptop. I don’t even want to fool around with trying to partition the hard drive (SSD) I would rather just run it in a virtual box. Vmware converter is not available for Ubuntu WTF!

    As with trying to do anything with Linux I have been reading and reading boards and articles. I even tried the Ubuntu forums (ask Ubuntu) they ask you why are you so stupid and don’t know anything. It’s so exasperating! I tried systembak and can’t shrink the file size down to make it less than 4 GB and besides the new laptop has no DVD player. !!! Sorry but it’s really frustrating.

  4. Is there Mac software I can use to easily create an exact duplicate backup of an external hard drive? Basically, I put all my photos from jobs on an external hard drive for archiving that I keep in my office next to my computer.

    Then I have a duplicate external I keep in a fireproof box at another location. I only copy everything over to my duplicate drive every month or so. But sometimes I’ve changed files on my main archive drive within folders I’ve already on the backup duplicate drive.

    Usually, I end up rewriting the entire drive overnight, which is a pain and takes forever. So my question is if there is a software I could use that would recognize the changes I’ve made to the archive drive and then apply just those changes to the backup drive so they match exactly? Thanks! *side note* I can’t use cloud or an online backup b/c it’s too many files and they are too large to upload
