Then that would leave you in a catch-22 situation. Fragmentation caused extra hard drive seeks - which according to your explaination would reduce the life of the drive. However, if you defragment so that extra hard drive seeks are eliminated, by the very act of defragmenting you are incurring extra seeks and therefore reduce the life of the hard drive. Catch-22.
That would also mean that actually using your hard drive will itself reduce its life - to ensure maximum hard drive life you would need to keep web browsing to a minimum, keep downloads to a minimum, only access files if it is absolutely necessary, etc... 🙂
I'm not buying your argument. Life expectancy of hard drives is far beyond what you need to worry about "incurring extra seeks" 🙂
