Simple hdd diagnostics

Users with years of experience in the hardware of the computer are well aware that in computer technology there is nothing of minor importance. Almost any failed part that makes up the system unit can lead to the inability to work with the computer. Today we will talk about the hard drive (hdd, screw, Hard drive, hard disk). Also in detail we will consider, how and for what check and diagnostics of a hard disk is carried out .

Many computer owners will be surprised by the fact that modern models of hard drives are designed for only 2-3 years of operation as part of the average home computer, after which they need to look for a replacement. Glorious times, when the diagnosis of hdd was only interesting theoretically, are in the past. Now every user should be able to check the status of the hard drive. This is a kind of payment for huge amounts of disk space, colossal recording density and high speed. Fortunately, the diagnosis of hdd is pretty simple.

Although the manufacturers of hard drives and BIOS motherboards have long established a software mechanism, without the participation of a person controlling the state of disks, it is still far from Perfection. And that's why. In 80% of cases, the wear of the surface of the magnetic plates inside the hard drive is so large that errors start to appear, and the warning message does not appear. Developers can understand - they sought to reduce the number of false positives, but, as often happens, overdone.

Diagnosing hdd is necessary if:

- The operating system normally works a week / month, after which there are various software errors that are temporarily fixed by reinstalling Windows;

- the speed of the hard disk has decreased significantly;

- The operating system often suggests performing a surface check for errors.

Diagnostics hdd is divided into two categories - a simple test by means of Windows and with the help of specialized programs. We recommend using the first option only if the cause of the errors is obvious. For example, the operating system rebooted after a sudden power outage Or pressing the Reset button. Open the label "Computer", on the right disk, press the right mouse button and follow the "Properties". Further everything is obvious: "Service - Check for errors". Here it is suggested to select the verification mode: superficial, for system errors and a thorough, checking disk sector-wise. Note that the sector scan will be started the next time Windows boots and it will take some time.

More effective use of applications from hard disk manufacturers. Owners of Seagate and Samsung hard drives should download Sea Tools, and for WD and Hitachi - Data Lifeguard. A similar hdd diagnostics involves specifying the desired hard drive in the program, if there are several, and selecting the SMART status view. The result should be without errors and warnings. The next step is to perform a short test and / or complete. True, the latter can require at least an hour of time. If an unreadable sector is found, the program will offer to repair it. The program interface is intuitive, so there should not be any difficulties.
