Current article has been written especially for the owners of the hard disk drives who frequently complain of the graceful degradation during the process of exploitation. Sometimes the decrease of productivity means the appearing of bad sectors on the surface of the hard disk, but in some cases such sectors can produce reading errors and some useful data can be lost.

Statistics that is provided by the local service centers demonstrates that actually a few of hard disks returned by the customers ought to be sent to the developer. Lots of cases are simply “false returns” when all the problems of the hard disk can be solved in twenty minutes. That is not necessary even to open the chassis.

There are lots of utilities - some unique solutions which are created just to be used by customers who have any complexities with hard disk usage. They are commonly named diagnostic and recovery tools due to their abilities. This article can be very useful as there are lots of clients who can't even imagine what this type of soft is intended to. The process of returning the hard disk to the seller or even to the producer is quite complicated and sometimes is not free of charge.

Some defects can appear simply during the action of producing as it is practically impossible to avoid such. Faulty sectors appear even on the most of modern hard disks. Several years ago some of developers even published the addresses of faulty sectors on the surface of the packing. It was great that developers didn't try to color the truth and bring the clients more info. With the appearing of S.M.A.R.T. technology special controller added into construction of the HDD watches over the creation of bad sectors and performs disk usage analysis automatically.

So the controller working along with S.M.A.R.T. system can prevent a lot of essential information from being lost as it would correct the mistakes occurred or recover data which can be lost. Read the rest of this entry »
