Cloning a hard drive results in corrupting the disk

SIW2 said:

It depends what sort of "clone" you want. Most so called cloning programs just copy the used sectors, automatically excluding certain things, and change the disk signature of the target as well as adjusting the boot entries(s). Even if you select all sectors, you will find , for example, that you can't access shadow copies after "cloning" with those programs. That is what macrium and most others do. Those are not true clones.

Some have extra features, such as allowing user defined exclusions - O&O Diskimage has extra features for that kind of thing.

If you want a true clone, you could use something like Clonezilla. It is included in parted magic - available here:

Because it is a true clone, you will need to detach the source drive before booting into the clone.
That is because windows will change the disk signature of one of the disks if two online disks have the same sig.

Thanks for the info.

Thanks for all the replies. Problem appears to be with the operating system not the cloning.
