Odd. The drive must be furiously reshuffling sectors or something,
or more likely pushing a piece of dirt around scuffing up more bits.
hdparm generally talks directly to a drive, not through the block
or filesystem layers. So the block, filesystem, and page-cache stuff
don't know anything about --read-sector and --write-sector.
