The problem comes from a very high rate of load/unload cycles of the heads

even earlier for this problem [2]
I use:
# hdparm -B 255 /dev/hda
to get rid of the problem with an ATA disk where I do not care that much
about power consumption. I do not know what the equivalent for a SATA
disk would be, but chances are it will be easier to track it down with the
reference above.
Although other power management features exist for SATA, for most hdparm
stuff PATA and SATA are pretty much the same. Same command set, simply
a new bus over which to transmit the commands. A great deal of early
SATA is actually bridged PATA, even.
