how do i make windows see 2 or more separate hdd from a 4tb hdd

[Ruin91]

soo......what trying to figure out is how i can make windows see 2 or 3 or 4 or more separate HDD so i can designate specific parts to whatever i want

EX:
windows would see a 4tb hard as a D and a E drive as if i had 2 physical hard drives plugged up

Open up Disk Management. Reduce the size of the primary partition.
Then create a new partition of the size you want the next drive to be. Assign it a drive letter.
If you still have unallocated space, create yet another partition. Assign it a drive letter.

When done, format the partitions you created. Once each partition is formatted, you should be able to use them.
