Scanning a Windows 7 hard drive. Checking and diagnosing the hard drive

Even the most polished and most secure operating system is by no means guaranteed against failures perceived by the user as errors. Particularly annoying are unknown and unexpectedly occurring errors, sometimes fraught with extremely unpleasant consequences.

It is not difficult to imagine the emotions of a person working on a complex document that is lost due to a Windows system crash. To avoid such problems, it is better to prepare for them in advance. And to do this, you need to be aware of how Windows 7 OS is checked for errors. Let us consider separately two serious questions related to the stated topic:

  • Checking Windows system files and registry.
  • Monitoring the status of your computer's hard drive.

Old-timers of the computer world well remember the utilities of the world-famous Peter Norton, not only the author of excellent books, but also the creator of programs under the “Norton utilities” brand. The first versions of these programs worked even before the advent of Windows - in the then popular MS DOS operating system. These utilities made it possible to detect the presence of errors on the hard drive and identify the presence of other DOS problems. We will be interested in similar tools for Windows.

Files and Registry

Checking OS files can be done in two ways: either using standard Windows tools or using third-party software. The OS has built-in file monitoring tools. To use their capabilities, you need to open a command line window and type the sfc command in it with the /scannow parameter, like this:

As a result, system files will be scanned to detect errors in them. The result will be displayed immediately in the command line window.

The information obtained can be analyzed (at least using the Internet), which can be useful for determining the degree of wear and tear of the OS and equipment. During operation, the program will try to correct all detected violations in system files on the disk.

Additional service, higher scanning quality and reliability of adjustments are provided by third-party software.

For example, the same package “Norton Utilities” (NU) for Windows. Although this tool is the most popular and powerful software package for dealing with OS and computer malfunctions, it still costs a lot of money. Especially in its “professional” configuration. Nowadays, you can find many free analogues of this creation on the Internet.

The Windows registry is the very place where, in addition to the information needed by the OS, a lot of all sorts of rubbish and garbage accumulates. Periodic cleaning of the registry is our direct responsibility. For this purpose, it is worth installing and periodically running the time-tested CCleaner utility (although NU also copes well with this task). Search for it online and download it.

Hard drive

The appearance of errors in the file structure on a hard drive is caused by wear on the disk surface, failures in Windows disk services (drivers), and positioning errors of the laser subsystem of the hard drive. You can check and disinfect your hard drive using methods similar to the previous ones. We'll look at the easiest way - running the standard disk error checking program that comes with Windows. To do this:

  • Open the “My Computer” shortcut, select the icon of any of the partitions (for example, “Local Disk C”).
  • Open the context menu with the right mouse button.
  • Select Properties. A window with tabs will open.
  • Go to the "Service" tab
  • Click on the “Run check” button.

The program will examine the partition and fix any problems. Perform the same operation with the remaining partitions.

This step-by-step instruction will help you check your hard drive for errors in Windows 7, 8.1, 10. We will do this via command line or through the explorer menu .

Please note that the use of any third parties is not provided. Everything is checked by the resources of the computer itself and the operating system. Why, you ask? Let me explain: this is done for the reason that most of the most powerful programs that are designed specifically for testing are little familiar and incomprehensible to the user. Therefore, when using programs little known to you, you can cause more damage to your computer.

Checking the hard drive using the command line

To begin with, it is necessary. In newer versions of Windows 8.1 and 10, this can be done by right-clicking on the menu “ Start", then select " Command line (administrator)».

In it (on the command line) enter the command chkdsk drive_letter: scan_parameters .

*Check Disk only works with drives that have been formatted in NTFS or FAT32.


Well, for example: chkdsk C: /F /R - the command indicates the check of drive C, and errors will be corrected automatically - parameter F, and the check of damaged sectors and an attempt to restore them - parameter R.

If you want to check the disk that the system is currently using, you will see a message stating that the scan can begin after rebooting the computer. Accordingly, you can refuse or agree ( Y - agree, N - refuse).

In other cases, after checking you will receive statistics of the data verified, errors found and sectors that were damaged.


If you want to find out the program parameters in more detail, you can run chkdsk, and specify a question mark as a parameter.

So, after the check is completed, you can see its results in the log Check Disk. To do this you need to click Win+R and enter eventvwr.msc. In the Windows Logs - Application section, search for the keyword Chkdsk.


Checking the hard drive through Windows Explorer

This is the easiest way to check your hard drive.

To do this, go to " My computer", and right-click on the disk that we want to check. Select " Properties» → Tab « Service» → « Check».

Typically, in Windows 8.1 and Windows 10, you will see a message saying that checking the disk is not required at this time. But it can be done forcibly.

By the way, in Windows 7 it is possible to select the appropriate items for checking, which allow you to enable checking and correct errors automatically.

Regardless of your operating system (Windows XP, Windows 7, Windows 8), go to Computer (My Computer, This Computer), right-click on the drive you want to check, select " Properties".

In the properties window, go to the "tab" Service" and click the " button Run check".

Check both boxes

Automatically fix system errors.

Scan and repair system sectors.

and press " Launch".

If you check the system volume (the disk on which the operating system is installed, usually drive C), you will see the message " Windows cannot verify the hard drive that is currently in use", click " Disk check schedule".

Then restart your computer/laptop; during boot, the process of checking and correcting errors on the disk will begin. It will last from several minutes to an hour (depending on the size of the partition and the physical characteristics of the hard drive). When finished, the operating system will boot.

Checking the hard drive using the chkdsk utility.

CHKDSK (short for check disk - disk check) is a standard application in the DOS and Microsoft Windows operating systems that checks a hard drive or floppy disk for file system errors (for example, the same sector is marked as belonging to two different files). CHKDSK can also fix file system errors it finds. (from Wikipedia)

In order to run the chkdsk utility, you need to run a command prompt with administrator rights, to do this:

IN Windows XP click - "Command line"

IN Windows 7 click "Start" - "All Programs" - "Accessories" "Command line" and select "Run as administrator".

IN Windows 8.1 right click on "Start" - "Command Prompt (Administrator)".

As a result, a command line console will open.

First of all, let's find out the syntax of the chkdsk utility:

CHKDSK [volume[[path]filename]] ]

Volume Specifies the mount point, volume name, or drive letter of the drive being checked, followed by a colon.
file name Files checked for fragmentation (FAT/FAT32 only).
/F Correcting disk errors.
/V For FAT/FAT32: output the full path and name of each file on the disk. For NTFS: display cleanup messages (if any).
/R Search for bad sectors and restore surviving contents (requires /F).
/L:size For NTFS only: Set the log file size (in KB). If a size is not specified, the current size value is displayed.
/X Pre-dismount the volume (if necessary). All open handles to this volume will be invalidated (requires /F).
/I NTFS only: Less strict checking of index entries.
/C NTFS only: skip checking for loops within folder structures.
/B NTFS only: Re-evaluate bad clusters on disk (requires /R)
The /I or /C options reduce Chkdsk execution time by skipping some volume checks.

Of all the command attributes, the two most often used to check a disk for errors are /f and /r. The final command looks like this:

chkdsk C:/F/R

With this command we will check partition C, correct errors on the disk and restore information from damaged sectors (if any).

After entering this command, you will be prompted to check the volume the next time the system reboots, click Y and a key Enter.

Now you need to reboot the system, when loading you will see a window prompting a check, do not click anything, just wait 10 seconds.

Checking for hard drive errors using Victoria.

The Victoria program is designed to check for errors on hard drives with IDE and Serial ATA interfaces. The program is a completely ready-made solution for a comprehensive, in-depth, and at the same time, the fastest possible assessment of the real technical condition of the HDD.

First of all, download the ISO image of the program from official website . Unzip the downloaded archive and burn it to a CD/DVD, as described in the article How to burn to CD/DVD . After this, boot from the burned disk, how to do this is described step by step in the article How to boot from a CD/DVD disk or USB flash drive .

After booting from the disk within 10 seconds, select the program for your device (Victoria for the computer will load by default).

The program interface will launch. Press the F2 key so that the program itself finds the disk; if this does not happen, you must do it manually. To do this, press the "P" key. The same will have to be done if the system has several hard drives and you need to select one of them. If you have hard drives with a SATA interface, then in the Select HDD port menu that appears, select - " Ext. PCI ATA/SATA". Move using the cursor keys "up", "down", and select using the "Enter" key.

Next, to check the disk surface, press the F4 key. In the HDD scan menu window: select the necessary scan parameters. By default, it is proposed to scan the entire disk from the beginning of "Start LBA: 0" to the end of "End LBA: 20971520". I recommend leaving these default values. The next menu item – I recommend leaving “Linear reading”, since it is intended for the fastest and most accurate diagnosis of the surface condition. In the fourth point, I recommend choosing the mode BB = Advanced REMAP since this mode checks the disk most efficiently and corrects errors on it without deleting information.

After this, a check for hard disk errors will start and bad areas will be corrected. This procedure can take from several tens of minutes to several hours. Depends on the volume and spindle speed.

When finished, remove the disc from the drive and restart the computer.

Test Dialog Box

Rice. 4 Test dialog box

Controls:

  • The FIRST SECTOR field is the initial logical number of the sector to be tested.
  • Field SIZE – the number of logical sector numbers for testing.
  • Field BLOCK SIZE – block size in sectors for testing.
  • Previous button – returns to the main program window.
  • Next button – adds a test to the task queue.
Test capabilities and limitations:
  • Only one surface test can be run at a time. This is due to the fact that the author of the program has not yet been able to obtain stable, high-quality results when running 2 or more tests simultaneously (on different drives).
  • A test in Verify mode can have a block size limit of 256, 16384 or 65536 sectors. This is due to the way Windows works.
  • The test in Verify mode may not work correctly on USB/Flash drives.
  • When testing in Verify mode, the drive reads a block of data into the internal buffer and checks its integrity; no data is transferred through the interface. The program measures the readiness time of the drive after performing this operation after each block and displays the results. Blocks are tested sequentially - from minimum to maximum.
  • When testing in Read mode, the drive reads data into the internal buffer, after which the data is transmitted through the interface and stored in the program's temporary buffer. The program measures the total time of drive readiness and data transfer after each block and displays the results. Blocks are tested sequentially - from minimum to maximum.
  • When testing in Erase mode, the program prepares a block of data filled with a special pattern with a sector number and transfers the data to the drive, the drive writes the received block ( the information in the block is irretrievably lost!). The program measures the total time of block transmission and recording and drive readiness after each block and displays the results. Blocks are tested sequentially - from minimum to maximum.
  • Testing in Butterfly Read mode is similar to testing in Read mode. The difference is in the order in which the blocks are tested. Blocks are processed in pairs. The first block in the first pair will be Block 0. The second block in the first pair will be Block N, where N is the last block of the given section. The next pair will be Block 1, Block N-1, etc. Testing ends in the middle of a given area. This test measures reading and positioning time.

Rice. 12 Temperature monitor for ATA/SATA disk

For SCSI drives, the information window contains 2 values. The second value is displayed in the taskbar.

The first value contains the maximum permissible temperature for the drive, the second shows the current temperature.

Rice. 13 Temperature monitor for SCSI disk

S.M.A.R.T. tests

The program allows you to run three types of S.M.A.R.T. tests:

  1. Short test – usually lasts 1-2 minutes. Checks the main components of the drive, and also scans a small area of ​​the drive surface and sectors located in the Pending-List (sectors that may contain read errors). The test is recommended for quickly assessing the condition of the drive.
  2. Extended test – usually lasts from 0.5 to 60 hours. Checks the main components of the drive, and also completely scans the surface of the drive.
  3. Conveyance test – usually lasts several minutes. Checks drive nodes and logs, which may indicate improper storage or transportation of the drive.

A SMART test can be selected from the SMART Tests dialog box, which is accessed by clicking the SMART TESTS button.

Rice. 14 SMART Tests Dialog Box

Once selected, the test will be added to the Tasks queue. S.M.A.R.T information window test can display the execution and completion status of a task.

Rice. 15 Information window S.M.A.R.T. test

Additional features

For ATA/SATA/USB/FireWire drives, the program allows you to change some parameters.

  1. AAM – function controls drive noise. Enabling this function allows you to reduce drive noise due to smoother positioning of the heads. At the same time, the drive loses a little performance during random access.
  2. APM function allows you to save drive power by temporarily reducing the rotation speed (or completely stopping) the drive spindle during idle time.
  3. PM – function allows you to set the spindle stop timer for a specific time. When this time is reached, the spindle will be stopped, provided that the drive is in idle mode. Accessing the drive by any program forces the spindle to spin up and the timer is reset to zero.
  4. The program also allows you to force stop or start the drive spindle. Accessing the drive by any program forces the spindle to spin.

Rice. 16 Information window for additional ATA/SATA drive capabilities

For SCSI drives, the program allows you to view defect lists and start/stop the spindle.

Rice. 17 Information window for additional SCSI drive capabilities

Using the Command Line

The program can build a command line to control certain drive parameters and save this line to a .bat or .cmd file. When such a file is launched, the program is called in the background, changes the drive parameters according to the specified ones, and closes automatically.

Version HDDScan 3.3 can be downloaded version 2.8


Support:

All modern homes have a desktop computer or laptop. Some people need it for games, others for work or study. In any case, photographs, some important records, contact details of people, necessary addresses, etc. are stored on the computer. And the place where all this information is stored is a hard drive.

It is not without reason that experienced programmers say that in a situation where a computer has a hard drive error, formatting it is a real disaster. After all, formatting is fraught with the loss of all information. But this is the case if appropriate measures are not taken. But if you notice some errors and malfunctions in the disk in time and correct them, then you can avoid this global catastrophe

The main causes of HDD problems are “bad” sectors - sections of disk space that are somehow damaged.

They are divided into physical and logical. The latter appear due to software errors and can be corrected, while physical ones cannot be corrected. In the latter case, you will have to replace the hard drive.

Such damaged areas can appear on both magnetic and standard SSD drives.

Causes of bad sectors and errors

Hard drive failures depend on the type of damaged areas:

  1. logical“broken” - displayed when there is malware or viruses, as well as when there is a sudden loss of power or power cable during recording;
  2. physical“broken” - found on a completely new product. Then you need to contact the manufacturer with a request to replace the product.

In magnetic drives, “broken” sectors can appear as a result of wear of the moving parts of the device, when foreign bodies get into the disk mechanism, or from a simple fall on the floor. In the latter case, the magnetic head of the disk is scratched, which leads to errors.

SSD drives give errors because they have tried to write any information to them many times.

It is quite possible to check the hard drive for “broken” sectors. Windows has an application called "chkdsk" (check disks). You need to open the folder on your desktop or in the Start menu "My computer" by clicking on the drive to be scanned. Using the context menu, select “Properties” - “Service”. Under the phrase “Check” there will be a button, by clicking on which you will be able to see the number of “broken” sectors.

During the test, the computer will eliminate errors in logical “broken” sectors, as well as mark areas with physical damage.

Attention! You can run the scan system manually, but if Windows independently detects “bad” sectors, the utility will launch itself when the system starts.

Checking utilities

Some software does not have built-in verification. For such cases, there are special programs that help identify “broken” sectors and errors and, if possible, correct them.

"Victoria"

It is a popular software for searching damaged areas. In addition to various methods of analyzing and reassigning problem areas, it has a function for searching for damaged contacts in a cable, as well as a function for assessing the performance of the hard drive. The only “disadvantage” of the program is the lack of official assemblies. Therefore, experts recommend using it separately from the OS.

"HDD Regenerator"

This utility uses its own methods to restore “bad” sectors (a combination of high and low signals) and supports any drive connection interfaces.

The downside is the high cost of the license ($90).

One of the best and multifunctional utilities for checking a device for damaged areas. Has the following functionality:

  • restores and reconfigures sectors;
  • fixes partition tables;
  • restores files and creates backup copies;
  • selects files in the table;
  • copies data from remote partitions;
  • creates backup copies of data.

This utility uses several methods to identify problems, as well as the ability to monitor SMART attributes and clean up the hard drive.

Important! The program supports all versions of Windows, but it does not scan/test the drive where the OS is installed.

With it you can scan one or several hard drives at the same time.

"Seagate Seatools" for Windows

The application supports all modern Windows systems. It can be used to do both basic and advanced testing. Simpler than "Seagate Seatools" for DOS, but less powerful.
