Well you could give it a try. I'd recommend a low level format (this will basically wipe out the whole drive clean). You can perfrom a low level format (a.k.a. write zeros) to drive either via CMD by using DISKPART, or by using software (for example some HDD diagnostic tools support low level formatting). After you're done with that kind of format you'd have to open Disk Management and initialize the drive as if it was a brand new internal HDD. After that you'd be able to partition and format as you see fit. Here's how to do those things:
Low level format:
Option 1 - DISKPART:
1. Open CMD (Command Prompt) as administrator.
2. type in
diskpart and press "enter"
3. type in
list disk and press "enter", you'll see all the storage devices connected to your computer and you should be able to recognize the drive you wish to format, by its size.
4. type in
select disk X and press "enter", where X is the number of the drive you wish to format, so make sure that you've selected the correct one - e.g. if the drive you wish to format is disk 1, type in select disk 1
5. type in
clean all and press "enter", then wait for the process to finish.
