Hi there,

I'm at a loss and now wondering if this is a potential GEM45 issue... after trawling the net.

- Astroberry - Pi4
- GEM45 (latest v.) bought late 2021.

I have plugged in the GEM45 to a usb hub as advised, tried powered and not powered.  Either the device won't register immediately and I need to restart Pi or services or the mount. Finally after registering it will work for a random period of time and then issue a 'Write Command Error: Write Error: Input/Output Error' - see attached the screenshot.

I then restart and may work again. After awhile it will do it again. I'm losing my freaking mind. Now after digging into the Pi's logs I can see at the exact same time the following:
Ignore the times on this log but its the same at each time associated with the syslog.

According to sites, it is meaning the device is faulty?  Does anyone have any thoughts on this?
