I was working fine with my Raspberry Pi 3 B+ rocking the Raspbian OS for about a week now. I could ssh in everyday and even installed Plex and streamed some movies. Today however, after I got a new external hard drive, I tried to format it using exFat but it didn't succeed. I did a reboot and now, it won't ssh in. It won't even ping... the raspberry pi won't even connect to LAN.
For the record I'm running a headless setup and I can't connect a monitor to troubleshoot the problem. When formatting I made sure to specify the right drive and partition (/dev/sdb1) so I didn't mess with the SD card containing the Raspbian OS.
Is some kind of error prompt preventing the OS startup ?

well, connect to a TV, you have one of those, right? a TV? because you watch movies
