Windows 10: Remove GPT partition and Reset USB flash drive back to factory setting

Hi,
I have a USB flash drive that has previously been used by Rufus so it has a GPT partition style. I'd like to wipe it clean and put it back to factory settings (MBR partition, FAT32 etc).
Ive been told before that GPT has a second (backup) partition table at the end of the disk and I'm not sure if clean deletes that. I know there is a Clean All option but I don't know what that does. Does a Full Format instead of a quick format do exactly the same thing as Clean All would do? I want to ensure that it is free from all GPT partitions. What is the correct way to do it with Diskpart? Below, Ive listed my standard commands for resetting a standard MBR flash drive. I always use convert MBR just to be sure *Smile What else do I need to add to these commands to ensure GPT partitioning is fully removed and the flash drive is properly returned to factory settings?
diskpart
list disk
select disk #
clean
convert mbr
create partition primary
format fs=fat32 quick
active
assign
exit

:)

 

How do you reset a USB flash drive back to factory settings?

Usually they are mbr partition table (not gpt), FAT32 and usually not marked active (active means a legacy BIOS based PC will boot it).

I'd make sure they are mbr not gpt, drop the "quick" so as to write zeros over the disk and not mark them active. Like this:

diskpart
list disk
select disk #
clean
convert mbr
create partition primary
format fs=fat32 quick
active
exit

It assigns the next free letter to the Windows PC you are running it on. So if you plug in a USB key and it assigns it letter J in File Explorer it will (try to) reserve this letter for that USB so next time you plug it in it gets the same letter. It doesn't write anything to the USB only in HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices on the PC concerned.

 

Partition a USB Flash Drive

This is the scary stuff that happens when you use Google:

'USB flash drives cannot be partitioned in the Windows operating if the drive is identified as removable media. The only way to partition the USB flash drive is to flip the removable bit so that it is recognized as fixed media instead which can be partitioned like any normal hard drive'

Infoz/Appz:
You searched for Boot It USB – Lancelhoff.com

Partition USB Flash Drives - gHacks Tech News

I got that from searching for 'partition flash drive'.

I should get paid for this.
