Shane, you mention 'shadow copy' and DAA your mentioning using Paragon. I'm assuming there is more to it than putting the new drive in the USB enclosure. Plugging it in as a drive. Copy/pasting the entire contents of my hard-drive and then swapping? This is where things are fuzzy for me, it looks like a software is needed?
Yes. There are boot sectors that need to copy over and having the drive mirrored over perfectly will guarantee you won't have any issues. Copy & paste method works too, but only after you re-install the OS and all your programs back in place. Then you copy/paste all your files back. Shadow copying bypasses all of that, just makes an exact copy of your filesystem and MBR onto the new drive.
