Or would it?
Async merge to sync request should be ok. But I wonder what happens with
hdparm, since it seems to trigger one of these tests. Very puzzling.
I'll dive in and take a look.
The code (written 10 years ago) isn't the best in the world,
and will be redone entirely for hdparm-7.0 this year.
But right now, it essentially does this:
loop:
seek( to sector zero );
read( 2MBytes );
repeat loop for 3 seconds
