What is the problem?
After flashing the SD card with etcher I can not open the SD card in Windows 10 at all. I get a warning saying "You need to format the disk in drive E: before you can use it" This is my second time setting up octoprint. I confirmed the SD card had no issues prior. Etcher validates the image.
What did you already try to solve it?
I formatted it. The volume persisted. I deleted all the Volumes in diskpart. (wouldnt allow me to in Disk management.) Used etcher again to write the image. SD card could net be opened, same error. Repeat without formatting this time. Same thing. Repeat, repeat.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
