Ubuntu Causing Laptop HDD Failure?

Has there been an update to this Ubuntu kills laptop HDDs story? It keeps popping up but I havenít seen anything else on it in a while. Anyone? Thanks to Vashypooh for reminding me about this one.

When switching to battery power, /etc/acpi/power.sh issues the command hdparm -B 1 to all block devices. This leads to extremely frequent load cycles. For example, my new thinkpad has already done well over 7000 load cycles -- in only 100 hours. That's at least one unloading per minute. Googling for "load unload cycles notebook OR laptop" shows that most laptop drives handle up to 600,000 such cycles. As these values clearly show, this issue is of high importance and should be fixed sooner rather than later.
