Package: acpi-support Version: 0.138-10 Severity: important Hi,
Just did a fresh install of Debian Wheezy and noticed that the count of load cycles of my hard-drive are increasing constantly and at an undesired frequency. This issue is famous and was already reported five years ago as #448673 At that time, acpi-support upstream was updated to include some 90-hdparm.sh scripts at /etc/acpi to perform hdparm operations at due time, which solved the problem for debian package too. But, Debian´s acpi-support upstream is linked to Ubuntu´s package (as seen in http://packages.qa.debian.org/a/acpi-support.html). Some time later, Ubuntu´s own hdparm and pm-utils packages evolved to include a chain of other scritps that already took care of calling hdparm with correct parameters, starting from pm-powersave at /etc/acpi/. Those changes only affected Ubuntu. So 90hdparm.sh scripts became redundand at Ubuntu, and they were removed from its package. As it is the upstream for Debian acpi-support, they were also removed after an update - see Debian acpi-support 0.129-1 changelog for details. However, Debian do not have the same solution using pm-utils, so basically the load cycle bug was free again. As discussed extensively in the past, this may not even be considered a bug, and definitely is a hardware manufacturer´s problem. Also, now there are easy solutions: (i) just installing laptop-mode-tools or (ii) copying one of the 90-hdparms.sh scripts, now supplied at /usr/share/doc/acpi-support/examples/acpi/, to /etc/pm/power.d/. But the fact is, for a fresh new install, even including laptop packages, some hard drives may start cycling to death. I only noticed this because of the head parking noise, and when checked already have ~3K cycles in 120 hours of use. Have I noticed only one year later, maybe the counter was already at number much closer to it´s factory "limits". Maybe I'm missing something here, but that's what I've found these days.
