Hello, I am affraid you are very wrong. The software did kill 2 of USB keys when I tried to make bootable Endevour OS from the iso image.
The first usb was very normally functioning sandisk extreme 64GB.
Based on what I was reading about the problem - inability to recover the partitions, I bought a new sandisk 256GB usb disk.
After trying to make the bootable usb, I got exactly the same result.
DISKPART> clean
DiskPart has encountered an error: Access is denied.
See the System Event Log for more information.
so the Etcher DID KILL both usb disks.
Unbelievable. I am lost for words. The worst possible software ever.
