Hi @justjeff,
Thanks for reaching out. Can you help with a little more details on what linux flavor are you trying to flash? And if I understand the drive is not being recognized on boot?
Also, to add some context to your original forum question here, we don’t etcher to any specific formatting. My colleague here (FAT32 and FAT issue - #10 by zrzka), has a good explanation on Etcher workinng to flash image.
Regards,
N
