Scenario
“Recently, I bought a new 4TB disk, now I need to clone my 2TB MBR disk to this new
4TB disk, could someone offered me some guidance in cloning 2TB MBR to 4TB GPT disk.
Thanks in advance!”
Clone 2TB MBR to 4TB disk
Sometimes you may want to replace your disk with a larger one, so that you can store
a large amount of data. In order to use the full 4TB disk space, you have to
initialize the 4TB disk to GPT partition style. GPT partition style requires UEFI
boot mode to load system from a GPT disk. And MBR disk uses Legacy BIOS boot mode.
If your original hard drive is an MBR disk, it will be tricky to clone hard drive
from MBR to GPT disk as they require different firmware.
