Smart hdd recovery. S.M.A.R.T

What is S.M.A.R.T.? Why do SMART errors occur and what does it mean? Below we will describe in detail the causes and methods for eliminating such problems.

Means S.M.A.R.T., showing hard drive errors (HDD or SSD) is a signal that some problems have occurred with the drive that affect the stability and operation of the computer.

In addition, such an error is a serious reason to think about safety of your important data, since due to a problematic drive you can simply lose all the information that almost impossible to restore.

What is SMART and what does it show?

"S.M.A.R.T." stands for "self-monitoring, analysis and reporting technology", which translated means “technology of self-diagnosis, analysis and reporting”.

Each hard drive connected via a SATA or ATA interface has a built-in S.M.A.R.T. system that allows you to perform the following functions:

Conduct analysis drive.
Correct software problems from HDD.
Scan surface hard drive.
Conduct program correction, cleaning or replacement damaged blocks.
Give ratings vital characteristics of the disk.
Keep reports about all hard drive parameters.

System S.M.A.R.T. allows you to provide the user with complete information about physical condition of the hard drive, a scoring method that can be used to calculate the approximate time of HDD failure. You can personally familiarize yourself with this system using the Victoria program or other analogues.

You can find out how to work, check and correct hard drive errors in the Victoria program in the article “”.

S.M.A.R.T. errors

As a rule, in a normally operating drive, the S.M.A.R.T. does not produce any errors even with low scores. This is due to the fact that the occurrence of errors is a signal of possible imminent disk failure.

S.M.A.R.T. errors always indicate some kind of malfunction or that some elements of the disk are practically have exhausted their resource. If the user begins to see such messages, you should think about the safety of your data, since now they can disappear at any moment!

Examples of SMART errors

Error "SMART failure predicted"

In this case, S.M.A.R.T. notifies the user about imminent disk failure. Important: if you see such a message on your computer, copy it urgently all important information and files to another medium, since this hard drive may become unusable at any time!

Error "S.M.A.R.T. status BAD"

This error indicates that some parameters of the hard drive are in poor condition (they have almost exhausted their resource). As in the first case, you should immediately make a backup of important data.

Error “the smart hard disk check has detected”

As with the previous two errors, the S.M.A.R.T. talks about imminent HDD failure.

Error codes and names may vary between different hard drives, motherboards, or BIOS versions, however, each of them is a signal to backup your files.

How to fix SMART error?

S.M.A.R.T. errors indicate imminent hard drive failure, therefore, error correction, as a rule, does not bring the desired result and the error remains. In addition to critical errors, there are other problems that can cause these types of messages. One such problem is elevated carrier temperature.

It can be viewed in the Victoria program in the SMART tab under the item 190 "Airflow temperature" for HDD. Or under the item 194 "Controller temperature" for SDD.

If this indicator is overestimated, measures should be taken to cooling the system unit:

Check cooler performance.
Clear dust.
Put additional cooler for better ventilation.

Another way to fix SMART errors is checking the drive for errors.

This can be done by going to the folder "My computer", by clicking right mouse button by disk or partition, select "Service" and running the check.

If the error was not corrected during the check, you should resort to disk defragmentation.

To do this while in properties disk, press the button "Optimize", select the required drive and press "Optimize".

If the error does not disappear after this, most likely the disk has simply exhausted its resource and soon he will become unreadable, and the user will only have to purchase a new HDD or SSD.

How to disable SMART check?

Disc with S.M.A.R.T error Maybe fail at any time, but this does not mean that you cannot continue to use it.

It is worth understanding that using such a disk should not imply storing any valuable information on it. Knowing this, you can carry out reset smart settings who will help disguise annoying errors.

To do this:

Step 1. Go to BIOS or UEFI(F2 or Delete button during loading) and go to the item "Advanced" and select the line "IDE Configuration" and press Enter. To navigate, use the arrows on your keyboard.

Step 2. On the screen that opens, you should find your drive and press Enter(hard drives are labeled “Hard Disc”).

Step 3. Scroll down the list and select an option SMART, press Enter and select the item "Disabled".

Step 4. Exit BIOS, applying and saving settings.

It is worth noting that on some systems this procedure may be performed slightly differently, but the principle of shutdown itself remains the same.

After disabling SMART errors will stop appearing, and the system will boot normally until until the HDD completely fails. In some situations, errors may appear in the OS itself; to do this, you should reject them several times, and then appear "Don't show again" button.

What to do if the data was lost?

In case of accidental formatting, deletion by viruses or loss of any important data, you should quickly return the lost information using the most effective method.

One such method is a data recovery program. RS Partition Recovery. This utility can quickly return remote photos, video files, audio tracks, pictures, documents and any other files, which disappeared from the drive for various reasons. has an advanced system for scanning and searching for deleted information, which allows you to find and restore even those files that were deleted quite a long time ago. More details about the capabilities and main features RS Partition Recovery can be found on the official website of the manufacturer

Equipped with a special self-diagnosis firmware S.M.A.R.T. (self-monitoring, analysis and reporting technology). This technology allows you to monitor the condition of the HDD, analyze its operation and predict failure. “SMART” monitors over 40 parameters, the result for each of which is entered into a special table. Analysis of S.M.A.R.T. statistics allows you to detect vulnerabilities and predict hard drive failure.

This article will tell you how to view the SMART of a hard drive, decipher its readings, and what parameters should be given special attention. It is worth noting that the information is presented in a structured manner, but special software is required to extract data from it.

How to view S.M.A.R.T. hard drive. Decoding parameters.

To check the “SMART” parameters, this function must be enabled in the system. This is true for computers manufactured before 2010. They have the HDD S.M.A.R.T option in the BIOS. Capability, the inclusion of which allows you to fully monitor “SMART”. On new PCs the question is “how to enable S.M.A.R.T. on your hard drive? not relevant – everything is enabled by default.

To view HDD status parameters, you need a special utility for working with HDD (Victoria, HD Tune, HDD Scan) or comprehensive diagnostic programs (Everest or its “successor” Aida64). They allow you to display the table in an easy to understand form.

Let's analyze the parameters using Victoria as an example. As can be seen from the image, the hard drive (in this case it is a 200 GB Seagate with an outdated IDE interface) does not support all “SMART” commands and fixes some parameters.

In the table header you can see the parameter ID, its name, the values of VAL, Wrst, Tresh and Raw, as well as the Health evaluation column.

ID – parameter number in the general list of analyzed criteria.
VAL is its current value in abstract units (usually a percentage of the ideal value).
Wrst is the worst value the hard drive has ever achieved.
Tresh is a conditional threshold for the VAL value, upon reaching which the system notifies of the impending “death” of the HDD.
RAW – expression of the VAL parameter in numerical format (number of operating hours/failures/errors/bugs).

The Health parameter allows you to assess the condition of the HDD for people unfamiliar with the intricacies of computer hardware or the English language. He assigns the usual rating from 1 to 5 points to each of them.

When analyzing the condition of the hard drive, you should pay attention to VAL (comparing with the Tresh column) and RAW (for an objective assessment). In the above example, it can be seen that the hard drive has experienced many read errors (for Seagate, Fujitsu and Samsung you don’t have to look at this column - all errors are recorded here) and has a long operating time (parameter 9). The table shows that the number of hardware error corrections (parameter 195) is quite high. The remaining “SMART” values are normal or close to it. It is important that parameter 5 (Reallocated Sectors Count) is normal. This means that the number of bad sectors is small (11 in this case) and the disk itself is not in danger yet.

If parameter 5 has alarming values, the health of the HDD is at risk. In the above screenshot, the Reallocated Sectors Count graph indicates that the hard drive is close to failure. In this case, this is a system failure (the discrepancy between the zero RAW value and the critical VAL value indicates this), and SMART restoration of the hard drive is required to bring it back to normal. But usually such information indicates that the HDD is about to break down and can no longer be used normally.

How to reset or restore S.M.A.R.T. hard drive

We cannot tell you in detail how to reset the SMART hard drive. Although this action is not criminal (unlike changing the IMEI of a smartphone), it can help unscrupulous traders sell faulty hard drives under the guise of new ones. But for users who need to know how to restore the SMART hard drive in order to return it to operation after a software failure, we will explain the situation in general terms.

To reset S.M.A.R.T. (just like other service tasks) a hard drive connection via the COM interface is required. To do this, manufacturers equip the HDD with a special connector of 4 or 5 pins. It is located next to the sockets for data cables and power supply. New computers often do not have a COM socket on the rear panel, so its functions are performed by a special USB-COM card.

Surely many LG Smart TV owners have encountered such a problem as: “Not enough memory. Please reload the page or go to another site." This notification pops up on the TV screen at the moment when the user tries to open some multimedia file for viewing, and it does not matter whether the Internet connection is via cable or wireless connection. The thing is that the TV does not have enough memory to load multimedia content. However, this problem does not always arise, and not immediately. If there is insufficient memory, a corresponding notification pops up.

It is clear that this problem only occurs when your TV is connected to the Internet (everything is fine during normal channel viewing), and you use the TV’s built-in browser to watch any online video. When playing music or launching games, this error may also occur.

The problem is in no way tied to a specific site, i.e. The error message can pop up on any site. Moreover, this message about the problem does not always appear and not immediately. Suppose you watched multimedia content for about 10 minutes and suddenly everything is interrupted and a notification about low memory is displayed on the display. Reloading the page allows you to correct this situation, but most likely not for long - for a few minutes.

Memory Features

It turns out that there is no way to expand the device's memory. A memory card or, more precisely, an external hard drive will not help here. Samsung TVs also have this problem. This situation occurs when you try to download a streaming video. The TV memory is full because... The image loads slower than online video and the required amount of memory simply does not always have time to be freed. It is recommended to open those sites in which the video in a common file is saved in blocks - then memory overflow does not occur.

There are not many options, because... You cannot expand the memory of a TV, as is the case with a computer. The only way out of this situation may be to install special applications on the TV that will allow you to get rid of this problem and watch movies, various videos, and listen to music from the Internet through them.

You can try updating your TV's software. There is hope that in later versions there will be no such “jambs” and memory will be used and distributed more correctly and more economically. After all, technology does not stand still, and this also applies to the development of the TV market. How can you clean the memory of an LG Smart TV easily and without problems?

Algorithm of actions:

Connect the TV to the Internet, no matter how. You can use Wi-fi, modem or cable.
Switch to Smart TV mode using the button on the remote control.
A browser window will open; you need to select a tab in the upper right corner, which will have several lines.
Select the line “Clear cache”. Click on the line and confirm this action and wait for the cleaning to complete.

TV capabilities

Using LG Smart TV, the user can open pages on the Internet, just like on a smartphone, laptop or desktop PC, using the browser built into the TV. “Surfing” the Internet using a remote control is not very convenient, although it is possible to purchase a keyboard for this purpose. But managing built-in Internet services using the remote control is very convenient, because they open instantly.

The range of these services available on smart TV depends on the country of residence of the owner and on the firmware version of the software. Usually this is Skype, Twitter, Facebook, YouTube, various TV channels. There is also access to multimedia resources.

Winchesters Seagate Barracuda very popular among personal computer users. Many discs last 5-10 years and have excellent “health” at this age. By the word “health” I mean both the functioning of the hard drive itself, its speed and stability, and the performance of its self-diagnosis and recovery system S.M.A.R.T.. Often, over many years of operation, the indicators of the self-diagnosis system S.M.A.R.T. change from the moment you start using the hard drive. In these indicators, the hard drive itself remembers such parameters as: the maximum temperature of the hard drive, the operating time of the hard drive (hours of operation), the number of turns on and off, the number of head parkings, etc. However, the most undesirable indicators that may appear after many years of hard drive operation are number of bad sectors.

Reasons for appearance bad sectors there are different ones. The main reason is time. Over time, areas with unstable reading of recorded information may appear on a disk, even a very high-quality one, especially if this information was recorded a very long time ago and the disk has not been used for a long time. Among the reasons may be the low quality of the hard drive platters themselves, poor-quality assembly, or the use of cheap materials in the manufacture of the HDD by the manufacturer.

However, there are times when bad sectors appear not because of the hard drive itself. I mean cases when the power is turned off while information is being written to the disk, or there is a defect in the SATA cable, or errors in the SATA controller on the computer motherboard, or unstable operation of the PC power supply (voltage surges along the 5V and 12V lines). In these cases, the self-diagnosis system can find on the surface of the hard drive from several pieces to several thousand so-called "software bads", i.e. areas where information cannot be read, because The checksums do not match the information itself that is written in these blocks. The diagnostic system often identifies them as unstable or bad and changes the system parameters S.M.A.R.T. not for the better. System S.M.A.R.T. It may even replace these blocks with good ones and display them in its indicators as Reallocated (moved), although the blocks themselves may be very good. This happens quite often, but not always.

The photo below shows a screenshot of the Victoria program with indicators S.M.A.R.T. problem disk. You can see more than a thousand sectors that have already been moved and hundreds that are preparing to move.

So what can we do to try to get the S.M.A.R.T numbers back? back to normal? We can reset the S.M.A.R.T. or transfer bad sectors to a hidden area of the self-diagnosis system, the so-called P (Slip) list. This operation does not guarantee that after resetting the indicators, these indicators will not appear again after a few days or weeks. If the disk really has bad sectors, the self-diagnosis system will identify them and mark them after some time of using the disk. So you most likely will not be able to make “candy” out of a truly “dead” hard drive.

This guide outlines the procedure for resetting S.M.A.R.T. for hard drives Seagate Barracuda 7200.11, Seagate Barracuda 7200.12, Seagate Barracuda ES, Seagate Barracuda ES.2. On other hard drives Seagate Barracuda I haven't checked, maybe the procedure is similar.

First, we need to get an RS232-to-TTL adapter. You can assemble an adapter based on the MAX232 chip as shown in the diagram:

Note on the diagram: If it is possible to connect to a stabilized voltage of +5V, then the circuit can be simplified by removing the 7805 stabilizer with two capacitors from it.

Alternative RS232-to-TTL adapter circuit.

The TV's built-in browser is capable of storing all your actions, and when you use various services, the TV's memory becomes full.

As a result, the owner of the TV cannot use it for its intended purpose. To avoid such inconveniences, you need to figure out how to clear the memory on an LG Smart TV so that the TV’s functions are restored.

During its operation, the owner of the device can perform many different functions that are available thanks to the capabilities of the TV, for example:

watch movies and listen to music;
use Smart TV through a browser;
viewing various files and photos;
use a keyboard for ease of use of Internet content;
manage TV applications.

All this leads to the accumulation of information in the internal storage device of the equipment, and as a result leads to the fact that there is not enough memory for further normal playback of various films and music on TV.

In this regard, periodic updating of the system is simply necessary to avoid overload.

Important: you should remember that this error occurs only if the Internet is connected to the TV; in the case when you watch channels in normal mode, such failures are excluded.

Failures can also occur when connecting to a computer, using a flash drive, or listening to music. At the same time, the occurrence of an error with information overload is in no way tied to any specific page. A corresponding message may appear when watching a movie or listening to music on any website, completely unexpectedly for the user.

You can reload the page, but this option will help for a few minutes, then the problem will make itself felt again.

At the same time, it is necessary to understand that it will not be possible to solve the current situation by increasing the memory, as can be done in the case of a computer.
A lot of smart technology faces such problems nowadays, since there is still no single constructive solution that would relieve the user of problems at the initial stages and solve the situation when it arises in one click.

For example, Samsung TV also faces a similar problem when it comes to downloading streaming videos. It experiences memory overflow due to slower loading of the image compared to online streaming.

I had to clean it. Therefore, to avoid the problem, it is recommended to use other applications only in those options where the video is posted in blocks.

How to clear memory on LG Smart TV

The occurrence of an error message indicates that the memory of the smart TV is overloaded; in order to cope with the temporary problem, you need to clear the cache in the lg smart TV browser.

This process is performed in 2 ways:

Clear cache of all applications:
To do this, you need to press Smart on the remote control to open the main menu;
in one of the upper corners, depending on the version of the TV, use the “Change” button;
select one of the online services that is not used and click “Delete” in the window that opens.
Cleaning the browser only:
by pressing the same “Smart” button, switch to Smart TV mode;
launch the browser and open its settings in the upper right corner;
Select “Clear cache” from the drop-down list and confirm the action.

After some time, the memory cleaning will be completely completed, the image playback speed will be restored, and the memory will be freed of unnecessary content along with the full message.

If this does not happen, you need to reload the page or go to reboot the TV.
In addition, you can prevent the problem without cleaning by wisely using the functionality of the TV and connecting to Windows using special applications that will prevent the memory from being overloaded and will ensure comfortable viewing and listening to any content.

At the same time, you can connect to the Internet at any time via Wi-fi by setting up a router.
The problem cannot be solved in any other way, even LG service specialists cannot give a detailed answer to the question of how to clear the memory, since all options that apply to the computer are excluded here, only the use of special applications that block the oversaturation of memory with information is available.

You can, of course, try to update the software on the TV and hope that after the update the situation will be resolved in a favorable direction, but this option does not always work for long.

Conclusion
The TV's memory overflow occurs due to the use of online content or listening to music. Solving this problem is quite easy, and there are several options - cleaning the browser or applications, and the third option is the smart use of the TV's resources so that there is no memory overload.

Unfortunately, at the constructive level, this problem has not been solved by the developers at the moment, but one can hope that new versions of the technology will still get rid of it, since progress is in constant development.

The latest drives are represented by intelligent devices that can analyze their status and promptly inform the user about problems. To achieve this, the hardware includes the original S.M.A.R.T. option.

Purpose of SMART technology.

The lion's share of disk drives in recent years operates using S.M.A.R.T. technology. The combination stands for self-monitoring, analysis and reporting technology , which in Russian sounds like a mechanism of self-control, analysis and reporting. Its first developments were released in 1995 and since then the technology has been constantly improved.

From the moment of production, the disk drive begins to read its current state, defining it using special parameters or attributes. They are located, accessible only by the built-in program. You can view the parameters using separate software, most often represented by utilities from the developers of a specific hard drive. Through them, inputs are sent to the drive, after which information about the current state of the disk will appear in the statistics log.

During the operation of the drive, the data presented within the parameters of the values are constantly changing. The parameters go from maximum values, guaranteeing high performance and efficiency, to minimum values, associated with a high probability of drive failure.

All attributes presented within the framework of S.M.A.R.T technology have a digital identifier. As a rule, it is common for drives of different versions, but there are exceptions. In this regard, the number 7 stands out, demonstrating errors in the placement of heads on the disk surface. For digital identifier is not relevant. Unlike 7, the number 9, which shows the total period of direct operation of the drive over the period of use, is supported by all types of HDD and SSD drives.

The structure of the parameters is represented by several fields demonstrating the state of the disk and its partitions during a specific period. Utilities designed for reading information display the following parameters on the screen:

ID – identification number
name – attribute name
VAL – its current state
Wrst – the worst indicator for the period of operation
Thresh – minimum performance threshold

S.M.A.R.T indicators

There are several most common parameters. With rare exceptions, they combine drives from most manufacturers, so:

Raw Read Error Rate – indicator of the number of reading errors
Throughput Performance - operational efficiency. Its decrease indicates the need for replacement
Spin Up Time – period of deployment of the drive into working state. An increase in the parameter indicates wear and tear or lack of nutrition
Start/Stop Count – an indicator of the number of times the disk deploys, which is initially limited by its mechanical structure
Reallocated Sectors Count – the attribute reflects the number of spare sectors. Information is redirected there in case of problems. Ideally, the number of such actions should be 0
Read Channel Margin – channel reserve. Nowadays, drives do without it
Seek Error Rate – Reflects the mechanical condition of the drive, including, among other things, demonstrating excessive vibration and overheating
Seek Time Performance – level of operational capabilities, relevant only for HDDs
Power-on Time – forecast of the duration of operation of the drive based on the period of operation. The maximum indicators are 100 and decrease to 0 over time
Spin-Up Retry Count – number of duplicate launch operations. Their increase indicates errors in the mechanical structure

These and other attributes with a red background indicate that the drive is in critical condition, which suggests an imminent failure. There is no specific standard that combines parameter indicators from different manufacturers. In each case, normal values are individual, reflected in the form of a background or status, where

Good - good indicator
Bad is a bad indicator.

Along with the attributes already mentioned, attention should be paid to such parameters as:

Recalibration Retries – number of takes during recalibration. Their increase indicates a mechanical problem
End-to-End error – Disadvantages of exchange operations
Reported UNC Errors - problems that can be resolved using hardware
G-sense error rate – the number of mechanical impacts on the disk. Detects inaccurate installation, collisions
Reallocation Event Count – a general indicator of information redirection operations. Records successful and unsuccessful operations
Current Pending Sector Count – number of potential drive sections to be replaced
Uncorrectable Sector Count – number of bad sectors that cannot be restored
UltraDMA CRC Error Count – problems with data redirection between the drive and PC

S.M.A.R.T check

S.M.A.R.T parameters are checked using special utilities from hard drive manufacturers. There are also universal programs for testing and checking disks. Among them are udisks, smartctl, hddscan, CrystalDiskInfo, Victoria, using which the user can assess the condition of the hard drive. In some cases, namely when working with RAID controllers, it is almost impossible to obtain disk attributes.

The minimum level of diagnostics is supported at the BIOS level. If the S.M.A.R.T. diagnostic mode is enabled, then if there are critical attribute values, the BIOS will not allow the operating system to boot.

So, when testing the condition of the hard drive, first of all, attention is paid to the specified S.M.A.R.T parameters. The main purpose of the technology is to predict the failure of a hard drive. If indicators deviate dangerously from the norm, it makes sense to transfer important information to other media.

And, most importantly, even if S.MA.R.T. there are no errors and everything is fine, this is not a guarantee that the disk will not break, so .

How to view S.M.A.R.T. hard drive. Decoding parameters.

In the table header you can see the parameter ID, its name, the values of VAL, Wrst, Tresh and Raw, as well as the Health evaluation column.

ID – parameter number in the general list of analyzed criteria.
VAL is its current value in abstract units (usually a percentage of the ideal value).
Wrst is the worst value the hard drive has ever achieved.
Tresh is a conditional threshold for the VAL value, upon reaching which the system notifies of the impending “death” of the HDD.
RAW – expression of the VAL parameter in numerical format (number of operating hours/failures/errors/bugs).

How to reset or restore S.M.A.R.T. hard drive

To reset S.M.A.R.T. (just like other service tasks) a hard drive connection via the COM interface is required. To do this, manufacturers equip the HDD with a special connector of 4 or 5 pins. It is located next to the sockets for data cables and power supply. New computers often do not have a COM socket on the rear panel, so its functions are performed by a special USB-COM card.
