Transferring vB Installation from one disk to another
 

This is more of a server question* but here it goes-

My forum has reached such a size that I need to start thinking of purchasing a larger/faster HDD for the server* and transferring the forum over to the new disk.

Is there any way to pretty much clone the contents of the current disk onto the new disk? Once I've done so* how to I point the server to use the new filesystem over the old one? I eventually want to get rid of the old disk.

I'm currently runing a Linux dedicated box. Any help would be appreciated!
