firstly are they partitions or virtual disks?

Check with Disk Management?

Well, one way to do so is just remove it from your VM *WITHOUT* deleting it from disk. That particular drive will be removed from your guest OS. So, assuming you have 3 "hard disks" in your VM's 'Edit Settings' area, you would remove hard disk "2" from your VM....again...withOUT deleting from disk. ONLY DO A REMOVE FROM VM operation. If you only have 1 or 2 'hard disks' in your VM's Edit Settings area, then as @hanccocka is suggesting, you have 2 partitions on a single VMDK volume and then it is just a matter of rt-clicking on D: and deleting the partition. And, if that is the case, I recommend remove the whole VMDK and recreate with the size you want. Don't create multiple partitions on a single VMDK if possible. It's not a recommended practice by VMware. Of course, if that is the case and you were to do so, you would need to back up your data first.
