I have a Macbook Pro running Mojave 10.14.4 and a My Cloud Home running version 5.0.5-104.
When I try to copy a folder (size ~15 GB) on the My Cloud Home, it progresses extremely slowly up to ~150 MB, and then freezes the Finder app for 10-15 minutes. I then get an error code 100057 with the message :
The operation can’t be completed.An unexpected error occurred (error code 100057)
Does anyone know what is going wrong ?
