I need to make a large virtual drive for virtual box at 3TB, however, the max size in virtual box appears to be 2TB. How can i make a 3TB virtual disk/drive? thanks.

You can not use the GUI to accomplish this, but you can with the command line like:

 vboxmanage createhd --filename 3TB.vdi --size 3000000 --format VDI --variant Standard


  • Great! does this also work for fixed size disks at this size?

  • Based on this I assume --variant Fixed would work for a 3T drive, but I have not tested it. Mar 24, 2014 at 17:14
