I don't know, I didn't actually test what these do, but according to the
hdparm(8) manual page,
-f Sync and flush the buffer cache for the device on exit. This
operation is also performed internally as part of the -t and -T
timings and other options.
-F Flush the on-drive write cache buffer (older drives may not
implement this).
So -f sounds relevant, but I can't really say for sure what they mean
("on exit"? exit from what?). But "-F" sounds exactly what I wanted.
You can try both, and tell us if one of them helped.
