Hi Lisa,

Yes, using GPIO to power Pi4 and USB 3.0 for the SSD. Still no luck.

All works when running completely from battery.

But external PSU into the UPS HAT and charging is happening, then the SSD will randomly disconnect, and I lose data on the SSD. Cause me to have to reflash.

Still unable to get this to work, tried all power connectivity options from the UPS board to the SSD, either via a direct link or via the USB 3.0. Problem is the same.

Thanks
