This article has been created especially for the owners of the hard disk drives who frequently complain of the graceful degradation during the action of usage. Sometimes the decrease of productivity implies the appearing of bad sectors on the surface of the hard disk, but in some cases such sectors may produce reading failure and some important data may be lost.

The officers of the local service center announce that there are lots of cases when clients return hard disks which don't work appropriately, but not all of them are sent to the producer. Lots of cases are just “false returns” when all the troubles of the hard disk may be resolved in twenty minutes. That is not essential even to open the chassis.

A lot of developers offer some special programs that are intended to help consumers to resolve some problems related to the hard disk drives. That type of software is called diagnostic and recovery tools. This article can be very helpful as there are lots of users who can't even imagine what that type of software is intended to. The process of returning the hard disk to the store or even to the developer is quite complicated and sometimes is requires some money.

Some defects may occur just during the process of producing as it is almost impossible to evade such. There are no developers that may promote the absolute absence of faulty areas. Several years ago some of producers even wrote the addresses of such sectors on the cover of the packing. Surely, these areas were blocked during the creation of the disk. In almost every modern hard disk there is a controller which executes some functions of disk usage analyzer. It tracks the actions of reading and writing any data and helps to evade errors.

In the newest HDD the same controller is able to track the information received with assistance of S.M.A.R.T. and take some measures to avoid the loss of useful information. Read the rest of this entry »
