How to remove all partitions from a disk and start from new

To add a bigger SSD to my tablet from 64 to 256 I bought a new SSD. I thought the new one would replace the old one Drive C: so i cloned the original. Unknown to me , novice, it cloned my 256 SSD as 64. When i installed the new SSD it was assigned as Drive A: at 64. So I have 180-something unallocated.

How do i get rid of the 64 partition to make all the 256-ish available as drive A: I tried Formatting but it simple formats as 64.

Is there a way of "formatting" or whatever to get back the unallocated space.

It may simply be a case of terminology. I have MiniTool Partition Wizard installed.

are we talking win10 ?

if so type in diskmgmt.msc in the box at the start menu and disk management will show you the unpartitioned space and if you right click on it you can set up the partition

^ Cheers I did try something like that. I think last resort I will un mount it and plug it into USB port and reformat or something.

In diskmanagement you should be able to expand the existing partition to the full size of the drive. There will be dire warnings to backup the content but that's not a problem for you.

Can you format a drive to be seen as drive A: or B: ?

I did something and now it is not recognized as A: anymore so i will de-mount and plug into USB and see what happens.

is it win 10 ?

Delete partition and then expand c: drive.

Yes. Now wondering if SSD needs an onboard driver to be recognized?

It uses the same Win10 included drivers as a traditional hard disk.
It should show up under Disk Management where you partion it, format it, and where you can change the allocated drive letter for it.

SSDs can be a problem when there is another spinning disk involved - which is normally a desktop setup

you have to unplug the spinning drives before win 10 install will recognise the SSD - but after you have installed win on the SSD you can plug the other drive(s) back in

if you run diskmgmt.msc and it can see the drive , then you can extend , delete , format the partition etc

if you are not sure how to use it - do a youtubr search

if you're on the command prompt, you can use Fdisk command. If you're using windows 10, just use windows built-in disk management tool by typing diskmgmt.msc. you can also use windows disc to boot into the boot menu and then use that tool to delete and recreate those drives. then there are other third party tools.

In the end I went to the memory shop in Fotune (as i pass it during my commute) where I bought the SSD and they "reset" or whatever back to original state.
