Re: Cloning Hard Disk

That only works when the filesystem is supported. It can also only

I guess I don't understand the difference ... I use `cp -a` regularly
when cloning/duplicating/backing-up my system. It is (almost) always
between disks/volumes of different sizes so I found this to be the
safest.


What I think that Sybren meant to say was: If your running kernel does not support one of the filesystems you want to copy, it won't work. Tahe NTFS for example. As you can only read it and cannot fully write to NTFS, you couldn't clone your filesystem via cp -a, but as dd copies bit by bit, it would even copy this filesystem to your new hdd.
