Well, it's hard to say what would work better if you can't explain
what the problem is with iotop. By default it sorts by io %, which
isn't necessarily the best view. Left and right arrows highlight and
sort by other columns, and it may be more useful to look at reads and
writes individually.
Depending on what's on the disk, it might be more useful to just use
lsof to see what files are open and try to understand what those might
be doing.
Thank you Michael.
I'll build up a list of these recommendations for here.
I'm looking at hdparm -C too.
No --help on that one.
man hdparm
-C Check the current IDE power mode status, which will always be
one of unknown (drive does not support this
command),
active/idle (normal operation), standby (low power
mode, drive
has spun down), or sleeping (lowest power mode, drive
is com‐
pletely shut down). The -S, -y, -Y, and -Z options can
be used
to manipulate the IDE power modes.
Thank you
