NVIDIA Shield / Plex Server / Changing hard drive storage and Server not available anymore

Hi,
Maybe it will help

i had to change, again, my external hard drive connected to my Nvidia Shield (for PMS) and… i had the same stupid issue: plex server doesn’t want to start while the nvidia shield does recognize the new HD

I fixed the problem by naming the new hard drive the same way than the old one

Other solution maybe:
