Usb drive not accessible after restart - system crashing

I’ve just started using Volumio again after having tested it out in an early version a few years ago.

It looks really good, and has improved greatly

I seem to be having an issue with accessing a usb drive. The files work initially, but after a restart the drive doesn’t appear. When I go to localhost/browse the loading circle appears in the centre of the screen, then the system restarts itself.

Any idea what the problem could be and how I could fix it.

Have you got a decent power supply to your usb drive?

Sorry, I meant USB flash drive - one of these
