I recently purchased a 5TB Seagate laptop hard drive. I cloned the disk, went through a few errors while doing it, and was ready to install it. But after turning my computer on with the new hard drive, I see that it reads as 2TB (1.82 to be exact) instead of 5TB.

Now, before you ask. I converted it to GPT, formatted it to NTFS, gave it a drive letter and fully extended the volume.

On the Partition Manager, it shows the hard drive at full capacity:

This is how the Explorer sees it.:

And the Disk Management shows this:

When I check the storage in the Windows settings, it shows as if almost all the space is being used when it's not even close:

This is where I'm stumped, and I have no idea how to fix it. Any ideas?
 
The orginal drive was probably a MBR formatted disk which only goes to 2TB max. To go past that it has to be GPT. Now to convert from MBR to GPT is two ways.


The windows way (Data Loss) which would require you to reinstall windows the right way (As a uEFI install and not a legacy BIOS install like it was)


Or find some MBR to GPT Conversion software. Most of them you have to buy though. Windows 10 Build 1703 does have a conversion tool built in as well but I have never used it and not sure if you can use it on the boot drive.

As I have said before, I've already converted it to GPT before I even started cloning the disk. I'm using this HDD for data storage of games only; I have a SSD for booting the OS.

Thing is, I did that when it was still fresh and unallocated. the GPT conversion succeeded then I proceeded to clone the disk.
