[RIPE Atlas Ambassadors] Most of the probe down because of USB Stick read-only

Hi, I just realised that most of my Ambassador Probes are offline probably caused by USB stick that turned into read-only mode. A couple of guys that I contacted and I give them instruction to reformat the USB stick said that the USBs are read only. I already told them to try to change the USB sticks, but looks like none are voluntarily (buy a new USB/use their USB stick) to change the USB sticks. Any idea how to revive the dead probe? Thank you Budiwijaya
