2TB partitionThe other day I was trying to install Windows Server on a 5TB disk array and I wanted to create one large 5TB partition.  When selecting the 5TB volume Windows always created a 2TB partition and would not create anything bigger.

To fix this 2TB partition limit you can do the following;

  • Within Windows Setup, press Shift+F10 to open a command prompt window.

Type in diskpart
Then type list disk (shows the disks)
Then select disk 0 (selects the only drive I had – my array)
Type clean
Lastly type convert gpt

  • Once complete go back into the setup windows and click the “Refresh” button in the advanced disk manager and you will see one single disk which you can create a partition larger than 2TB.
