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? – Joe Feb 7 '14 at 22:21
  • "free software if it is possible" This is you asking that. – takendarkk Feb 7 '14 at 22:26

Try this command and options to avoid the process to stop when it find some bad sectors

dd conv=noerror,sync if=<whatever> of=<whatever>


conv=CONVS convert the file as per the comma separated symbol list

Each CONV symbol may be:

noerror continue after read errors

sync pad every input block with NULs to ibs-size; when used with block or unblock, pad with spaces rather than NULs

More info Man dd command

  • What is this? it is a part of a command, or part of dd? – Joe Feb 8 '14 at 19:30
