What is CHS addressingA long time ago, when the capacity of the hard disk was very small, people used a similar structure to produce hard disks. That is, each track of a hard disk disc has the same number of sectors. This results in the so-called csh 3D parameter (Disk Geometry). That is, the number of heads (Heads), the number of cylinders (cylinders), the number of sectors (sectors), and the corresponding CHS
At the end of October, Microsoft released a black-screen patch for XP users-the Windows Edition Value-Added Program Notice, and Microsoft also released a patch similar to the office verification.

Each disk has two sides, that is, the top and bottom sides of the disk, which are sequentially numbered from top to bottom from "0. The disk is divided into many concentric circles during formatting. These concentric circle tracks are called tracks ). The track starts from 0 in sequence. A cylinder is a cylinder consisting of the same track on all disks. The head on each cylinder starts from "0" from top to bottom. The operating system stores information on the hard disk in the form of a sector
First look at the hard disk structure diagramThe so-called CHS is cylinder-head-sector to locate a sector.Each disc has two faces, each of which corresponds to a head, the head on the disk to draw a circle, forming a track, different heads of the same radius of the circular cylinder, each track on the bytes area called sector.Cylinder number: The outermost one is 0, which in turn increases;Head number: The top of the 0, followed by increasing;Sector n

1. OverviewAs a user of Windows Azure, the most worrying thing about using Azure is that before the end of the month, the pre-set costs are running out (the two bill chart below is the one I hate to see). But by carefully analyzing your own expense list and discovering that the vast majority of costs are spent on virtual machines, and that Azure's virtual machines are billed by boot time, there is a compelling need to find a solution to save the overhead of virtual machines. The simplest solutio
