Can I 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. Here is a typical case:

"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!” - from Tom's Hardware

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. However, you cannot clone an MBR to a GPT because the cloned disk is not bootable. Since MBR doesn't support 4TB drives, cloning a 2TB MBR to a 4TB drive means you need to convert GPT to MBR.

You can try AOMEI Partition Assistant to convert MBR to GPT or convert GPT to MBR without data loss. After the conversion is complete, you can directly use the tool to clone the 2TB MBR to a 4TB disk.AOMEI Partition Assistant offers a one-stop service.
