I run laptop mode and it is very effective. I can usually let my hard=20
drive spin up only once every 20 minutes for about 10 seconds. However,=20
during the time when I run laptop mode, I mainly browse the web and do=20
things over ssh session. So I don't really know how well it works if you=20
have to constantly write to the disk during your work. I have a T43.

If you choose to wrap a foam around the HD, you need to seriously=20
consider the heat dissipation issue: head dissipation is already limited=20
in the cramped laptop space, and heat pose a serious threat to laptop=20
reliabilities. You might want to monitor your drive temperature using=20
hddtemp---there's a plugin for gkrellm if you use that. (I know frequent=20
spin up will also wear out drive, but I think every 20 minutes is=20
probably fine.)
