For reading, the surface is moved past the read/write head, and the bits that are present induce an electrical current across the gap. See hard disk. THIS DEFINITION IS FOR PERSONAL USE ONLY.

A hard disk drive uses magnetism to store data on a rotating disk. A read/write head floats above the spinning disk reading ...

The data are rendered unreadable, and the drive has to be replaced. However, in some cases, the data can be recovered (see data recovery). The read/write head on a hard disk hovers above the ...

A hard drive stores data on a series of spinning ... Credit: Surachit/CC BY-SA 3.0 The actuator arm above positions the read-write heads over the correct area of the drive to read or write ...

One fun aspect of 1970s-era hard disk drives ... corroded DIP switches, to head alignment sensors, a defective analog board and ultimately a reported bad read-write head. Frustratingly, even ...

But slow SSD read/write speed problems ... Another reason an SSD drive is slow could be that the boot sequence is wrongly configured. If the first priority is given to the hard drive, instead ...

There's more to the fastest hard drive than read or write speeds. You need to think about all kinds of factors including how you aim to use it, the volume of data involved, and whether you're ...

Ever wondered how SSDs read and write data, or what determines their performance? Our tech explainer has you covered.
