How can i format an old HDD that was from an old laptop and still has the partitions for the OS, C and D drives?

The HDD was from my dad's old laptop and when it stopped working a technician just removed the drive and put it in a sata to usb adapter, and now i wanna use the HDD as a normal storage drive but it has the 3 partitions and i can't just delete any program or windows files.

 

I don't know if by just right clicking and selecting format on the main drive would delete the other 2 drives.

 

Also i found that i can use dban, already burned it in a flash drive since i've never used it i don't know if it'll be safer to unplug my personal SSD and HDD from my pc.

find the drive, right click and delete all volumes (partitions) then format free space as NTFS or whatever filesystem you use

That worked, thanks!
