I do not know how many GB of material you have backed up or much information about what you have done.
I would recover the material to my computer and or other media like dvd or flash drives.
When the material is ‘safe’ I would download Macrium for free and use it to “image” to your external hard drive.
If your material is not removed until it is in the pc it is safe. It is then that you can remove the smart ware and anything else in the Book. Start from scratch so to speak.
As I said, when you first plug he Book in, do not use any software. Say no if asked. You will see the Book look for drivers(plug n play).
Using the Macrium you have downloaded you can now"image" the material you want to the external hard drive.
I keep it simple by selecting my entire system to be ‘imaged’. This way you can retieve a single file or your whole system.
I had an incident where my pc needed to be reformatted and reinstalled. Instead I used Macrium to recover the "image’ that was on the externaldrive.
It came back perfectly.
I also have bought Acronis for my other pc but macrium does the job well.
Don’t make a mess for yourself.
Go to forums like Major Geeks and What the Tech. Register so you can log in and ask questions like you are asking me. I know it sounds like a lot of work but you will be better off and it is not all that complicated.
If you take one step at a time and write things on a notepad, you can make an interesting task of this which will benefit you without errors.
Think twice before clicking once.
Write back if you wish but do not be discouraged. It is up to you if you are willing to put a little effort in because there are never quick fixes to a good job.
Remenber, ultimately once you have imaged your system, you can recover any of it as long as your machine is working.
