[VoIP] Fedora, CentOS or What?

[Shane Young]

With identical drives, it's easy to do in Linux.  I've never done it  
with drives of different geometry.

I would do it this way (though it's been a long time since I've done it)

Have a system which is not booting from the drive you want to clone.

Attach the source drive as the primary on your second IDE controller.
Attach the destination drive as the secondary on your second IDE controller.

Boot the system and log in.

Type dd if=/dev/hdc of=/dev/hdd

This should copy the formating, partitioning, file structure  
(everything, really) from the first drive to the second drive.


I used to do this a lot when I needed to create a bootable floppy disk  
from a disk image.
