I have a raspberry pi 4 with libreelec 11.0.3 and there is a 5tb hard drive connected to the raspberry and everything is working fine.
However when i delete a file( or files) from the disk then when i restart the raspberry the disk disapears.
When I check the disk in windows for errors (windows i telling me there are no errors) and i connect the disk again to the raspberry i can see the disk again and everything is working fine. This happened als so in libreelec 11.0.1
In libreelec 10 and 9 this bug did not happen.
