A Neat Look At How Hard Drives Work
If you’re like me, you have a bazillion photographs backed up on external hard drives, but have you ever wondered how digital photographs are stored on the magnetic surface of a platter spinning at thousands of rotations per minute? This interesting video provides a neat look at how hard drives work, though it will probably also convince you to back up your photographs by some other means as well (e.g. online or on discs). The engineering that makes hard drives possible is amazing!
