Hi, Richard,
Did you try some more times and there is the same problem? When you
complete cp files and do ejecting, is there any doubtful warning message
in dmesg information?
According to the fstyp output from your device, I have not seen any
suspicious information, but the "Bytes Per Sector 2048" is a bit
special. The value in most current disk devices is 512. I found there
were some bugs in previous nv about mount failure in 2k sector size,
e.g. 6391828, 6393753. Not sure it is related. But if your issue exists
always, you can backup your contents first, and then reformat your
device to test again.
Thanks
Guoqing
