    Why is only 2TB of my new 3TB drive showing up ?


    I bought a 3 TB drive today, to replace my, existing 1 TB drive which was 95% full. This is my "D" drive and is
    data only, no OS on it. Its actually all my WEB server data, for IIS.
    My plan was to use Paragon Hard Disk manager and clone my existing 1 TB, D drive to the new 3 TB drive which was
    on an external ESATA. In the past I've successfully used Paragon to clone my OS drives from spinning to SSD.
    Sometimes the Source drive has been bigger than Target, other times vice-versa...have never had an issue.
    Being this is data only, my main reason for using a clone instead of copy is to capture all the security, network
    and other drive specific windows settings...not having to go in and redo all that. I'm figuring if Paragon has
    successfully cloned an OS, this should be a breeze...and it was ...cloned and swapped.

    My issue, I notice my 3 TB drive, windows is only "seeing" 2TB. (2048 GB) and leaving 746.52 GB as unallocated.

    I'm guessing I could make an "E" drive of 746 GB...but, I'd rather have all 3TB on the "D" drive.
    Using Minitool partition wizard I try to extend...and get "not enough free space" (I'm using 779 GB of the 2048 GB)

    Going back to Paragon...and trying to resize the partition...it shows the max as 2,097,151MB

    I'm sure...or am hoping this is an easy solution, but don't want to "just try something" and loose a lot of data.

    Please advise.

    It's because it is using the MBR partition scheme and not GPT partitioning. MBR has a total disk size limit of 2 TB.

    What’s the Difference Between GPT and MBR When Partitioning a Drive?

    Well, that would explain it. So, the answer is ...to start over and use GPT? I assume I would do this at the windows disk manager and go from there, reformat to 3TB...and then clone my other 1TB (old drive) back to it?

    Use MiniTool Partition Wizard to convert the disc to GPT and then expand the partition to fill the empty space.

    Ah...too late, I used windows manger to convert...lost my data, but, paragon will slap it back on there. I did notice in paragon, it saw it as 3TB...but, the "max clone' is still 2 TB. This is fine, as my data is less than half of that. I assume when done, I may again only have a 2 TB drive, but, now should be able to extend to capture the unallocated not that it is GPT?

    I did the convert in windows drive manager to GPT, then recloned with PARAGON, ..it saw the 3 TB...but, when I cloned it said max size is 2TB...I see now, it is "cloning" an MBR drive, to a GPT formatted drive....when I try to extend i am getting:

    What do I do in this case? I want to clone to keep the many settings on this drive. Is there a way to convert without loosing my data?

    I used Paragon to convert MBR to GPT, and this seems to have worked. It had to reboot and run during start up for exclusive access. I have checked disk size, it is now 3TB, and no data loss.

    I have security, permissions and windows indexing on this drive that I did not want to redo, this seems to have cloned over successfully.
