Current text has been written particularly for the possessors of the hard disk drives that frequently complain of the graceful degradation during the process of usage. At best it may produce the decreasing of the effectiveness and appearing of the faulty sectors on the surface of the disk. At worst it may lead to the loss of important information saved there.

People who work in local service centers announce that it is not always necessary to send the disk returned by clients to the developer. Professionals call such cases as “wrong returns”. It means that the origins of the problems may be eliminated and it may take just about several minutes.

To resolve the problems that have been occurred during the process of exploitation of the hard disk customers may use some program utilities. They are frequently named diagnostic and recovery tools due to their functions. We made decision to write more about these solutions as many users even do not know that such utilities exist. Before the hard disk will be returned to the developer the staff of the service center should perform some tests that can demand a lot of time.

Some defects may appear simply during the action of development as it is almost impossible to evade such. There are no producers that may promote the complete absence of faulty sectors. There were some models of the hard disks that had determined faulty sectors and their addresses were established on the packing. The developers had to block such areas for the proper usability of sold hard disks. With the appearing of S.M.A.R.T. technology special controller included into construction of the HDD watches over the formation of such sectors and performs disk usage analysis automatically.

So the controller operating along with S.M.A.R.T. system can prevent much essential data from being lost as it will eliminate the errors occurred or recover data that can be lost. Read the rest of this entry »
