Since you are getting a new hard drive,remove the old hard drive and put into a generic USB drive case. Put the new hard drive in and reload your operating system. You can then plug in the USB drive and copy off files you want to save.
So I messed up my computer. I copied stuff from C to D and then tried to put it back. Unfortunately, now that I need to back up all my files and everything... it won't work. I've tried 5 times now to backup my system and it keeps FAILING.
I have a lot of pictures and files I want to save... so...
What can I do?
In the end I would like to build up from scratch with my new hard drive, but I would also like to keep everything that is on my computer now.
Please help!
