there is ifno about dd command on this link http://wiki.linuxquestions.org/wiki/Dd
. but i like something tar better , it would be faster. again, i guess if you image the drive , dd does exactly image the drive, so you might need bigger hard drive than source disk.
I also like to know there is imaging command in linux, like ghost?? faster and dont exactly need bigger hard disk. and doesnt have problems as many as ghost.
Also can someone point out how to tar bigger than 2G, please!!!!
