So, it looks like some sort of insane USB driver bug? I turned the Probox on and all drives came up and have stayed up. So, as a test I grabbed a USB stick and stuck it in a USB 3 port one of the PC's front ports and the USB icon came on solid, the USB stick appeared and was readable. It looked like it was having problems with a USB device, so physically unplugged the probox from the PC in case the probox's USB port had become flaky, still no change. I turned the probox off, dropped the VPN and closed all programs, and no change, icon was still going in and out, ran webroot and malwarebytes, no issues there.
In sync with that, my USB drive tank Probox with 8 drives actually did disappear and then come back online, and the probox started checking disks as if it was being connected to and disconnected from the PC.
Ok, got a bit of a strange one this morning which happened after I opened an excel file from the office via VPN could be just a coincidence it happened at that time though.Īnyway, the USB drive icon in the sys tray disappeared and then appeared and started randomly switching between those states.
