2 TB drive size limit in Clone Disk?

Thread needs solution

Trying to clone a 1TB drive to a new 3TB drive.  Disk Clone will only use 2TB of the new drive.Any way to fix this?

I suspect you are cloning an MBR disk, in which case the max supported partition size is 2TB. The disk space is not lost, you just create a new partition for the remaining space. Alternatively elect to change to GPT which supports larger partition sizes.

I am sure there is a means of either doing clone or recovery where as part of the process it uses GPT rather than MBR for the "new" disk, but cannot find it at the moment. This may have already happened, check to see if the new disk is MBR or GPT. If so you can increase the partition size using utility such as the free MiniTool that many of us use.

Jim, is the new 3TB disk going to be your Windows OS drive?  If so, in order to use GPT your system must be using UEFI.

Please take a read of the ATI 2018 User Guide: Migration method

This has a long list of the different permutations of BIOS modes that can be encountered and what these will result in creating as far as the target drive format is concerned.

One example from the above:

UEFI-booted system, MBR, UEFI supported

In this step of the wizard, you need to select the destination hard disk.

Currently your system contains:

System: UEFI-booted

Source partition style: MBR

Operating system on the source disk: Windows, booting in UEFI is supported

If you migrate the system to the selected disk:

After migration, the destination partition style will be converted to GPT and you will be able to boot from it.

Destination disk after migration:

System: UEFI-booted

Partition style: GPT

Operating system: Windows, booting in UEFI is supported

Disk size: the entire disk space is available

You can find more information about the migration procedure in Migration method section.

You can check how your Windows OS currently boots for the BIOS mode by running the msinfo32 command then looking at the BIOS mode value.  This will show as either Legacy or as UEFI.
