i think this is what happened:
diskpart reads it as RAW. i can set the read-only flag to yes or no, put i can't change the current read-only state.
i'm going to boot my windows 7 laptop into gparted and see what it says. i'll then boot into arch using a recovery usb key and see if i can verify that the above is the case.
i don't know what the point of this. it's some stupid monkeys from a backwards religion trying to assert some kind of jungle logic.
it's a waste of my fucking time.
it would suggest that they have access to the root account on my chromebook, which i've suspected for a while. i would need to restore from firmware and probably flash my router, but i don't have fucking time for this. i don't want to waste my life doing this boring bullshit.
