I used Etcher to write a “Zen Installer” .iso-image to my new Intenso USB-stick. I should say that I have no idea how they prepared the Image but I was be able to install Archlinux with it.
Then I wanted to Flash a Manjaro .iso-image on this stick but Etcher detected the stick, I can start but Etcher was not be able to write. Something must have locked it, it seems.
After that I started my Manjaro Installation and gparted. Gparted detects that this USB-stick has a iso9660 on /dev/sdb. I was able to write a Partition table on this stick and Format it with FAT32(dev/sdb1).
After that I was been able to write a other .iso with Etcher on this stick.
So I ask:
What are the requirements for Etcher to use a USB-stick?
Wouldnt it be nice if Etcher could detect the Problem and Partition and Format the stick if this is required?
