How to Set a USB Flash Drive Partition as Inactive?


I have a USB flash drive which for some reason is formatted with an active partition.

I usually use Minitool Partition Wizard to set a partition as inactive but for some reason it doesn't work on this flash drive. I also tried booting from the Partition Wizard boot disk but that won't set the partition inactive either. I even deleted the partition and reformatted the flash drive but it popped up as active again!

How can I force the partition to be set inactive? Note it's quite an old USB flash drive so I'm wondering if there something in the hardware which stops it being set inactive?

insert USB

use diskpart

Diskpart
List volume
select volume # (# being volume number for usb stick)
Inactive

insert USB

use diskpart
Diskpart
List volume
select volume # (# being volume number for usb stick)
Inactive
I tried that but I get the message "There is no partition selected" (see screenshot). I then tried the command select partition 1 and that didn't work either.


Use:
......
list disk
select disk #
select partition 1
inactive

Thanks TG..

Use:
......
list disk
select disk #
select partition 1
inactive
That doesn't work either - seen screenshot. I'm thinking there may be a hardware issue with this flash drive since all my other ones work as expected.


Show us a screen shot of Disk Management.

Here is the Disk Management layout:

I am guessing there is more than one partition on the usb drive, but Windows does not recognise multiple partitions. It could be there is a hidden msr partition or something like that as well interfering with things.

Even disk management might not show all partitions.

I would use both minitools partition manager, and even then it might not work?

It may be necessary to use gparted (linux).

I was surprised the other when I tried to diskpart/clean an hdd with some hidden partitions, it did not totally nuke the drive, and I had to manually delete a hidden partition (somehow I had two msr partitions).

Your disk 4 is already inactive.

From dispart, the stick only has 1 partition.

@steveC
What bothers me is why you cannot select the partition. Since this stick is only 500MB, I guess it's pretty old and certain stick won't even allow to create as bootable.
