    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?

    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.

    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.

    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.
    @cereberus
    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.
