[SOLVED] Partition

[seane01]

Hello,

Does this look ok or are there things that could be optimized? Thanks in advance!

Hi,

Assuming this is a computer that came preinstalled, this looks ok.

I would not recommend any attempts at optimizing, it will only create a mess for you.

I have no idea what the 9 GB could be though. Is there a way to know?

You can assign it a letter and look through the files and folders, that's the only partition for which it won't hurt to look into that doesn't have a letter. By assigning a partition a letter, it will become visible in explorer.

 

[seane01]

There is no option to assign a letter to the 9GB and the 128 Mb. The others i can assign a letter.

What options do you have?

Do not touch the other partitions, that can cause problems

 

[seane01]

These are the options:

Let's try this

Open an elevated powershell and enter these commands, press enter with each line and note the volume number of the volume whose size is 9GB for the command of selecting the volume

diskpart
list volume
select volume <volume number>
assign letter=R

 

[seane01]

Just to be sure, is it volume 6?

 

[axe0]

If you're going by the 6 from 'Schijf 0 partitie 6', the number can be different with diskpart and you may accidentally alter a different volume that we don't want to alter.

I did a little comparison myself by comparing recovery partition of size 520MB in diskpart and disk management, it indicates partition 5 in disk management but in diskpart it's volume 4. If you want confirmation, please post the output of the list volume command

Ok thanks, but the volume isn't shown:

Hmm, I think I've seen this phenomenon of a random partition at the end of a disk before, I believe its meant to be the backup of your GPT header, which from what I remember, is used for automatic recovery if your GPT header gets corrupted. It seems to vary in size based on the OS and disk manufacturer I believe.

If you use diskpart again:

diskpart
list disk
select disk #
list partition
select partition #
detail partition

You will want to get the partition which matches your partition size.

From what I see on the UEFI docs, looks like it's indeed the GPT backup

I just checked my machine and it had a 1GB partition at the end which was marked as part of the Window RE. It's possibility it could be that too but the backup GPT will be around there somewhere.

Thanks, it looks like it's for Intel Fast Flash (iFFS), which is part of IRST, more information here: How to use Intel Rapid Start Technology to improve system startup from hibernation. | Dell UK

 

[seane01]

Thanks, is this necessary or can this be removed? Because i don't use this Intel Rapid Start Technology, at least as far as i know of

Well, it's a backup. Normally you would not need to use a backup but at the same time it's good to have a backup for something so important as that.

You could delete it, but I don't know if you can add the 9GB free space to a different partition with Minitool Partition Wizard. With the built-in disk management, that's not possible unless the free space is directly located on the right of the partition that you want to add the free space to if I'm not mistaken, which it won't be in this instance.

I would leave all partitions untouched. It does not look like you need the additional space and the 9GB might just end up as free space that can't be added to any partition if Minitool Partition Wizard can't add it to any partition either.
