Formatted the disk, made clone instead of image as it will be exact replica of current disk and thats what i want, will just put away backup disk and use it if this one crashes. Only drawback is that the unused space where partition is copied gets wasted, but image wont give me freedom to boot from it i think so cloned it.
How you backup ur data ?
