There is something really strange with Etcher. Indeed, two of my USB stick were down after using it. I use Etcher on Mac OS Catalina to create a install media of the OS. This work just fine. I was able to install Mac OS Catalina. But after, when I need to format de USB and use it for something else, here is were issues starts. USB seems clearly to be unfunctionnal.
On Mac OS, I can see the install media created. But when I try with disk utility to do stuff, it is not possible. If I try the command mentionned here, not working. It is the same for Linux. I can see the install media created but I can’t do anything on it, even with the terminal.
On Windows, the disk is restricted, I don’t have the write permission to do what I want. I have use cmd and also diskpart with chmod, clear attributes, etc… even regedit. But no way to use the usb again. With AOMEI, I can erase the disk but that all. All the rest is not available because of the fact that disk is not mounted or sometime dynamic. It seems to have no partition et no volume on the USB. The format is stil GPT.
I am stuck between “You don’t have to permission to write” and “Error E/S”.
@dtischler Could you please provide me some help as the last USB key was working just perfectly and now its dead…
Thanks a lot
