@jay52592 IDE is for the data transwer, you only need Molex cable when you're doing this.

@GraspingReality Information is stored in flash memory as tiny microscopic 'fuses' which are broken (0) or linked (1) these kind of memory chips can only be written to a number of times before the links become un'flashable' and are therefore only suitable for long term storage where information is not required to be updated continuously. Standard RAM uses continuous power to refresh the on/off state of transistors, which obvioulsy lose their information if power is lost.

@tkktkt true. Its only a spin off from Tape Drives that use time information tables to locate files. Eg. File 'A' is located at 3min 16 sec. To get to file 'A' timing pulses are written on the tape and the hardware counts them (fast search) to get to 3min 16 sec then reads the data from there. A hard drive uses formatting, the OS writes the file allocation table to the drive and this is a known and stored variable that just tells the head to shift position to get to exactly the right location.

@jay52592 The video explains its a demo. The procedures are hard encoded into the hard drives rom on the drive circuit, which you cant see in the video as it is under the drive casing. =]

@GabrielGroverMan the voice coil actuator is very much like how a speaker works in your hi fi. The sound produced is caused by various voltages oscilating at given frequencies to produce sound in a paper cone. The head/s on a hard drive have a set of very powerful magnets to help keep it in a given programmable position using the same method., voltages and frequencies fed through its coil to define its position.
