You must make sure something else is not resetting it (like a thinkpad
BIOS). Search for HD APM in http://www.thinkwiki.org for details on when a
BIOS would usually do this. Read the linux-thinkpad mailinglist archives
(its address is in the mailinglists page of http://www.thinkwiki.org) for
more details.
It is also useful to know which HD, and in which platform
(motherboard/laptop) you're having problems on. Also, make sure you are
running the latest BIOS released by your vendor.
Oh, and if it is a thinkpad HD, *check for the availability of HD firmware
upgrades*. Although, by now, it looks like your driver has spent >90% of
its designed head unload lifetime, so I'd just call in for a replacement
under warranty (complain it is making strange noises too often -- it is not
a lie, as it will be making "click" noises due to the constant head
unloading) if possible.
