Notebook HD problems with linux

This post has alerted me of a big problem on laptop HDs that apparently happens to Linux users (according to other post from this same author, Vista has the same issue). It seems that the power-saving technologies keep telling the hard drive heads to sleep, while Linux keeps telling the drive to read or write something down. This wake-sleep-wake process consumes the life-time of the drivers to the point of failling hardware within an year.
The current workaround is to shutdown power management to hard disks with hdparm “hdparm -B 254 /dev/sda” (or /dev/hda, depending on your configuration).
More detailed info can be found on Ubuntu Bug at Launchpad.
