Disk management question

[spoony77]

Hi people
I have reinstalled windows due to an annoying issue and now I have my old windows ssd as a spare drive in my system.
My question is - I would like to remove the old windows installation via disk management and use the space as a new drive, so I opened up disk management and the hard drive shows up as split into 3 parts - a recovery partition (450mb), a EFI system partition (100mb) and the primary partition (223gb)....
Now I am used to just deleting these partitions during windows install but disk management doesn't give the option to delete them?
So how do I remove them and create just a single formatted partition on this drive to use as extra storage?
Regards

A 3rd party tool such as Paragon Disk Manager will allow you to delete the extra unwanted partitions

Ok thanks - so there's no method from within windows itself then

Can be done using diskpart which is a windows command line tool

Surely you can just reformat the whole drive, or just take it offline, then reformat (from within disk mgmt) ?

Open a command prompt
type diskpart
type list disk
It will show you a list of the drives
type select disk x
where x is the number of the disk you are going to wipe. If you get this wrong, you are going to wipe the wrong disk!!!
type list disk
Confirm you have the correct disk selected (it will have an asterisk to the left)
When you are ABSOLUTELY SURE you have the correct disk selected
type clean
type exit

And you're done.

Summary:

diskpart
list disk
select disk x
list disk
clean
exit
