Package: acpi-support
Version: 0.103-1
Severity: critical
Justification: causes serious data loss
(See also https://launchpad.net/bug59695.html for corresponding Ubuntu bug!)
On a notebook with ACPI enabled, in battery mode the disk is retracted after
1 minute of idling. This leads to ~7000 retracts in only 100 hrs total
runtime - and a notebook disk can handle only up to 600.000 retracts; this
decreases the total life of a dsik to ~138 days, which is not even a half
year.
As a workaround, add the following to /etc/hdparm.conf:
/dev/sda {
apm = 255
}
and the following must be put into a file called 99-fix-disk.sh:
#!/bin/sh
hdparm -B 255 /dev/sda
This file has to be copied to:
/etc/acpi/suspend.d/
/etc/acpi/resume.d/
/etc/acpi/start.d/
which shuts off the idling behaviour and saves a huge lot of disk life.
