No, that would plain stupid on both our parts.  :)
The --write-sector flag is allowed only for non-partitions by hdparm itself.

But other flags commonly used by distros at boot time
seem to be triggering the current in-kernel noise.
Dunno which flags, I'm just ignoring them and waiting
for the noise message to get reverted.

Cheers
