Sorry, it hadn't occurred to me that the OP wasn't just doing that
(because they had said they used "Safely Remove" in Windows).
Nor had it occurred to me that one might need a bettery of tools
like iotop, hdparm, iostat, pidstat, perf top, and the rest,
rather than just unmounting. I thought they wanted a belt and braces
method, a bit of redundancy.
So it's just the usual Pose Problem A, Solve Problem B.
Cheers,
David.
