My initial thought is that this is a bad idea.
But let's assume that I can't take a USB stick into my lab to run a live-Linux distro, and my computer has only 2-SATA ports. I have one 80GB SATA drive that I want to
dd to my new 1TB drive.
Both drives will take my only 2 SATA ports, I have no IDE ports, I have no USB CDROM drive, and cannot use a USB stick.
Is it a bad idea to try to
dd from a running OS to a new drive? Will the drive boot? I can format/partition the extra free space later, I just need to know if my new drive will boot before I begin the process.
