[Info-vax] Is there the equivalent of $ MONITOR PROCESS/TOPD on other OSes?

[alanfe...@gmail.com]

On my Mac, sometimes one of the external Time Machine drives just starts making noise non-stop. I have to dismount and power-cycle it. But I wonder what process is writing to it or reading from it. The macOS Activity Monitor doesn't have it. And I don't think the Unix 'top'  command has it either. Not that I could find, anyway.

Does _any_ other OS have this feature, $ MONITOR PROC/TOPDIO

I ask here in the hopes of not having to explain MONITOR PROC/TOPDIO to people in other forums.

TIA.
