I've tried clonezilla live cd, and I got an image but in a kind of folder. I would need an .img file or something because afterwards I will use some images together, but that is other story.
I also used dd if=/dev/sda of=~/disk1.img
but it doesn't finish the image because the disk has 500GB and the image just about 100MB the first time and 2GB the second time, so I think that stops before finish for any reason I'm not aware of.
Do you know any way of doing an image of a disk?

I don't think that I'm asking that. I just want to create an image and I don't know how to do it. Should I change the way of asking this question? – None – 2014-02-07T22:21:40.763
"free software if it is possible" This is you asking that. – takendarkk – 2014-02-07T22:26:03.050
If the problem was that, it is already resolved! – None – 2014-02-07T22:30:58.013

Yes, guys, it is not about programming, but is it worth not to help therefor? Joe, dd is already free software :-) Is the partition where you want to save the copy different from sda? What about ddrescue ? You could mount a third partition or drive and use ddrescue if=/dev/sda of=/dev/sdb/disk1.img /dev/sdc/errorlog.txt – None – 2014-02-07T22:49:42.353

Yes, I bought a disk of 4TB for that purpose. Could I recover the copy in the point it stopped? – Joe – 2014-02-08T19:29:13.857
