If linux tends to write to /var/log/* every 30s, then the heads can park/unpark every 30s.
There was a direct link between Reallocated Sectors Count and how quickly the drive would fail [...] Even one Uncorrectable sector count would lead to most drives being unusable within 3months
We find that the group of drives with scan errors are ten times more likely to fail than the group with no errors. This effect is also noticed when we further break down the groups by disk model. From Figure 8 we see a drastic and quick decrease in survival probability after the first scan error (left graph). A little over 70% of the drives survive the first 8 months after their first scan error.
Get/set the Western Digital (WD) Green Drive's "idle3" timeout value. This timeout controls how often the drive parks its heads and enters a low power consumption state. The factory default is eight (8) seconds, which is a very poor choice for use with Linux. Leaving it at the default will result in hundreds of thousands of head load/unload cycles in a very short period of time.
Compaq placed IntelliSafe in the public domain by presenting its specification for the ATA environment, SFF-8035, to the Small Form Factor Committee on May 12, 1995.
Attribute 194 (Temperature Celsius) behaves strangely on my Seagate disk
The files access time update, while mandated by POSIX, is causing lots of disks access; even accessing files on disk cache may wake the ATA or USB bus.
