[rhelv6-list] Heavy laptop disk cycling?

Just noticed that since I installed RHEL 6 back in Nov, my laptop hard
disk (from a new T410) has gone through about 200,000 cycles, as
confirmed by the smartctl -a /dev/sda command. (If I remember right,
hard drives expire at around 600,000 cycles.)

(In contrast, the oldest hard drive my server on which I installed RHEL
5 a year ago has gone through 228 cycles.)

As this seems reminiscent of an Ubuntu 8.04 issue (ref
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695 ),
I've been experimenting with different hdparm readahead settings without
much success (yet). 

I don't see a Red Hat bug on the subject -- has anyone here seen one, or
has gone through a similar issue?
