I have used Balena Etcher hundreds of times all worked fine.
Today I tried to flash an ISO with crucial firmware update tool to an usb stick. First it worked, tried to boot, didnt work. Okay wanted to reflash. Didnt work to flash. Sure use diskpart and clean (W10), what? clean not working, access denied. Checking the event log "sectors cannot be put to null. 5@010100F - strange. Downlaoded AOMEI partition tool. It said it did everythign fine, but windows wont recognize the drive. I then tried to change the registry Error - "storagedevicepolicies" is missing | Media is write protected
Didnt help either. Okay USB drive (Lexar) might be broken. Try another one. Same thing. So basically two bricked, USB drives - anyone any idea?
