Software to copy an entire disk to another ?
in [Storage]

From: Louis on 10 Jan 2008 07:12 Hello ! An hard disk partition table is corrupted and one of its partitions is no longer accessible/visible. Before using a partition recovery tool, I'd like to make a copy of this entire disk - including the areas which are now in "twilight zone". Most, if not all, disk imaging/cloning softwares I know will image/clone existing partitions - which would obviously exclude the unaccessible partition of the corrupted disk. Can you recommend a software to make an exact bit-per-bit copy of the entire disk ? Thanks PS: while on the subject, any experience/opinion on partition recovery softwares such as Acronis Disk Director or Active@ Partition Recovery ?

Similar functionality to dd, but you get a progress indicator. Comparison for same contents can be done with the standard utility "cmp" under Linux, just use the disk device special files as input, e.g. "cmp /dev/sda /dev/sdb". Arno

DO NOT touch/write anything to the original (watch out for those automatic stuff). -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!
