I have an empty drive disk for file storing it has no installed system image, I need to separate it on two partitions. I have Ubuntu 16 on another physical drive.

When I try via Gparted to

  1. Resize existent ext4
  2. Click 'New' on unallocated right part of gparted drive volume bar I am getting an error:

It is not possible to create more than 1 primary partition

If you want more partitions you should first create an extended partition. Such a partition can contain other partitions. Because an extended partition is also a primary partition it might be necessary to remove a primary partition first."

If there a another type of filesystem I need to reformat ext4 prior to creating 2nd partition? How it's called, what size does it have to be if I need two ext4 partitions afterwards?

Caution, questions: How to resize partitions? How to create partition on single partitioned disk are irrelevant, I've already proceeded through those receipts and getting an error DURING them.

Also Create partition from free space - cannot create more than 4 partitions is irrelevant, cause I have an empty drive which has no files, not the dual-boot case, not more than 4 partitions problem.

Update some comments answered:

I) > sudo apt-get install gparted

gparted is already the newest version (0.25.0-1)
libparted : 3.2

II) > lsblk

If I make the assumption that you have a /dev/sda1 partition on your disk and that you have some unallocated space after it then the following should work using fdisk:

  1. Backup any data on the disk that you cannot afford to lose.
  2. Open a terminal and type sudo fdisk /dev/sda
  3. At the fdisk prompt type the letter p. This will show you what is currently on the disk you are working on and is just a check that it’s the right disk.
  4. At the fdisk prompt type the letter n followed by the letter p. This tells fdisk that you want a new primary partition.
  5. Accept the default for the partition number and the first sector. To use all of the remaining unallocated space accept the default for the last sector.
  6. At the fdisk prompt type the letter p. Again this is a check that the changes you are making are what you wanted.
  7. Finally at the fdisk prompt type the letter w to write the changes to the disk.

Exit fdisk and you should be done. Good luck!
