”Failure Trends in a Large Disk Drive Population” (PDF). Proceedings of the 5th USENIX Conference on File and Storage Technologies (FAST’07). 2007. https://static.googleusercontent.com/media/research.google.com/en//archive/disk_failures.pdf. ”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.”.

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.”
