When I copying some files to an external device,after completion.I try to eject the device…it shows a buffering circle near the device. When I eject forcefully ,the data were lost.Some logs were generated.
On that time I can’t able to shutdown the system also .Instead
I need to press the power button manually.
This happens rarely even I faced this issue in both ubuntu and Debian.
Can anyone say why the problem occurs!?
