Can't access all space on HDD

[Naith123]

Didn't seem to get any responses in the storage subforum so hoping for more eyes here.  The issue is on Disk 1 there is 3 paritions in Disk Managment.  The Data Partition I have been using for a while, a random EFI partition that I think may be left over from a ubuntu install. (HDD was added a while after Windows was installed so don't think linked) Finally as you can see there is a 1tb unallocated partition which formerly belonged to Ubuntu.  I would ideally like to expand the Data partition as much as possible, not the end of the world if I can't get rid of the EFI partition.  The drive is a seagate barracuda 4tb drive.

 

 

Attempting to expand the Data Partition gives the following error.

 

Attempting to create a new simple volume gives the following error and create a small 1mb partition.

 

 

 

Having a look at the disk in Diskpart shows the following.

 

 

Any ideas what I can do to get my storage back?

Is there anything currently stored on the disk? If so can it be moved long enough to reformat the drive??

Just fixed it, my housemate changed the drive type to basic from dynamic allowing me to remove the partition via Minitool Disk wizard.

 

Any idea why that was a problem?
