Bug description
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.
Please see for yourself how often your drive is load cycling:
smartctl -d ata -a /dev/sda
(This command is for an SATA drive; you'll need to install the smartmontools package first.)
See also http://paul.luon.net/journal/hacking/BrokenHDDs.html for a rather dramatic account of the effects the current default values may have.
Just in case the load/unload timeout depends on the specific laptop or disk model, here are my system specifications:
ThinkPad Z60m & Hitachi HTS541080G9SA00 disk (80GB)
-------------------------
1) I added the following lines to my hdparm.conf:
/dev/sda {
apm = 255
}
2) I created a file /etc/acpi/resume.d/99-stop-hitachi-madness.sh
with the following contents:
#!/bin/sh
hdparm -B 255 /dev/sda
(Workaround posted by Gilles Schintgen in the above linkie)

Well, that would be a problem on my asus laptop - if the 2.6.22 kernel in gutsy didn't totally fuck up acpi so much that I have to boot with acpi=off!
No power management = no problem :)
PS im a little annoyed at this regression - it worked fine on feisty and earlier kernels. (yes yes bug report - there's heaps already filed and no progress I can see) :) -----
