Advice 1: How to repair hard disk of laptop

Any hard drive sooner or later fails. At this point it is important to quickly restore the essential files preserved on this medium. When working with the hard drive of mobile computer there are several solutions to the problem.
How to repair hard disk of laptop
You will need
  • - Mount'n'Drive;
  • - бокс SATA-USB.
Quite often a failing hard diskand is associated with the failure of the boot sector. This means that on this device you cannot install the operating system and use it as a primary drive. Try to connect this hard disk as a secondary disk.
The main catch is that mobile computers cannot connect directly two the internal storage. Get an external box that allows you to connect hard diskwith IDE or SATA to a USB port.
Install the hard drive in the box and connect it to the mobile computer. Of course, you'll need another hard diskon which operating system is installed.
Internal drives laptops with SATA interface can be connected to desktop computers. To do this, remove the Winchester from the body of the laptop and remove the carriage. Be sure to remove the mounting slide from the hard disk.
Connect the drive to the motherboard of a desktop computer, using the ribbon cable from the SATA connectors. Turn on the computer. Wait some time until the operating system detects the new drive.
Check out the standard ability to copy information from the hard disk. Extract the files you need and format the device. If the Winchester is not available for work, install the program Mount''n Drive. Start it.
Just right click the icon of the corrupted disk. Select "Mount" and enter any letter drive. Wait for the creation of a new local volume.
Open its contents using Windows Explorer. Remove the important files and disable hard drive. It should be noted that the read speed of a mounted driveand can be very small. Don't waste time copying information that is easy to recover other ways.

Advice 2 : How to recover bad sectors on hard drives

Despite the growing popularity of flash memory, the mechanical reading is recorded to the hard drive data. Often this method works on the surface of the plates arise bad sectors. And usually they cannot be recovered, but there are exceptions.
How to recover bad sectors on hard drives
The issue of security of information on your hard diske forces developers to think about data storage to the smallest detail. However, in conditions of real operation of your device, all their tricks do not help.

Why spoil sector

The principle of operation of a mechanical hard drive is very simple. There are several round magnetic plates. By him "run" the read head and looking for the right information. When the mechanism of the hard disk is subjected to vibration or sharp blows on the surface of the disk can occur microscopic scratches. This leads to damage of sectors and loss of data, programs, books, music or movies.
How would you not carefully exploited the PC hard disk can still appear bad sectors.

If the Winchester has worked for several years may disrupt its integrity. Any ingested dust is a potential cause of bad sectors.

Add to this the power surges, abrupt shutdown of PC and simply improper use of the computer and of the reasons for the destruction of information will be much more.

Is there a way out

If there are bad sectors, do not immediately panic and quickly change the hardware. There are ways, or mark problem areas so that they do not cause problems. Either fix the damage with the help of some special programs.
When there are bad sectors, there are two ways you can use your private software or third-party.

The simplest thing you can do is run a surface scan of the drives. To do this, right click on the failed logical partition, choose "Properties" then "tools" and "validate", tick "scan for and attempt recovery of bad sectors". The system will scan the disc, find the error and either return the sector to a working state, or will mark them as failed to read head passed them by and did not create "brakes" in the work.

For more advanced users, you can recommend the program HDD Regenerator. It works on a physical level and helps to cope with the problem where a standard disk check is useless. The regenerator conducts in-depth work and in most cases, the sector returns to a normal state. You will not lose data and will considerably increase the service life of the hard drive.

There are many other programs even such, to understand which only real "hackers" or people with experience. However, in most cases, the two above-described products. They are time tested and have helped in many difficult cases.
