In badan oo naga mid ah ayaa la kulmey Hard Disk-ga ama SSD-ga. Qaar naga mid ah ayaa xitaa isku dayay in aan wax badan ka ogaanno isku halaynta hard drives-ka iyo shaqada saadaasha dahsoon ee ka mid ah tignoolajiyada loo yaqaan SMART . Mid ayaa laga yaabaa inuu ku doodo in SMART uusan ahayn mid la isku halleyn karo maadaama uusan saadaaliyay guul darro dhammaan kiisaska. Xaqiiqadani qayb ahaan waa run, laakiin shaqada dhabta ah ee gudaha nidaamkan is-ilaalinta maaha mid sahlan, markaa aynu eegno sida ay SMART u shaqeyso. Waxaan sidoo kale ku tusin doonaa sida loo hubiyo heerka HDD SMART , iyo sidoo kale heerka adag ee waditaanka SMART :

Waa maxay SMART (HDD & SSD)?

SMART waa nidaam la socda macluumaadka gudaha ee darawalkaaga. ^{(SMART is a system that monitors the internal information of your drive.)}Magaceeda xariifnimada ah runtii waa erey la soo gaabiyay oo loogu talagalay Kormeerka, Falanqaynta, iyo Tignoolajiyada Warbixinta^{(Self-Monitoring, Analysis, and Reporting Technology)} . SMART , oo sidoo kale loo qoro SMART , waa tignoolajiyada laga helo gudaha HDD-yada^(HDDs) iyo SSD^(SSDs) -yada . Way ka madax banaan tahay nidaamkaaga hawlgalka, BIOS , ama software kale.

Muxuu SMART u qabtaa HDD-yada^(HDDs) iyo SSD^(SSDs) -yada ?

SMART waxa la alifay sababtoo ah kombayutarada waxa ay u baahdeen shay la socon kara xaalada caafimaad ee darawaladooda adag Taas macnaheedu waa, si cad, in SMART loo malaynayo inuu awoodo inuu kuu sheego haddii darawalka adag ama darawalka adag ee gobolka uu ku dhow yahay inuu joojiyo shaqada^{(SMART should supposedly be able to tell you if your hard drive or solid-state drive is about to stop working)} !

Sidee buu SMART taas u sameeyaa? Waxaa laga yaabaa in aad isku daydo inaad u maleyso in SMART uu si sixir u qiyaasi karo haddii darawalkaagu caafimaad qabo. 🙂 Waxa ay qabato waa sheeko gebi ahaanba ka duwan, in kastoo. SMART waxa ay isha ku haysaa doorsoomayaal taxane ah^{(SMART keeps track of a series of variables)} oo nambarkooda iyo nooca ay ku kala duwan yihiin wadista ilaa wadista, kuwaas oo tilmaamaya isku halayntiisa^{(indicators of its reliability)} . Haddii aad rabto inaad fikrad qoto dheer ka hesho dhammaan sifooyinka SMART , maadaama ay jiraan ilaa 50 ka mid ah (heerka qaladka akhrinta ceyriinka, wakhtiga dib-u-celinta, khaladaadka aan la saxin ee la soo sheegay, wakhtiga awoodda, tirada wareegga culeyska, iwm.) , booqo boggan^{(visit this webpage)} .

Si kastaba ha noqotee, ogow taas, marka laga reebo isku dayo gaar ah ( Google , Backblaze ), inta badan SMART . xogtu waa mid aan sharci ahayn. Nidaamku wuxuu bixiyaa xog badan oo gudaha ah. Weli, waxaa jira is-khilaafyo badan oo ku jira tirakoobka sababtoo ah qaar badan oo ka mid ah soosaarayaasha darawalada adag waxay isticmaalaan qeexitaanno iyo cabbiro kala duwan. Tusaale ahaan, qaar ka mid ah soosaarayaasha ayaa kaydiya xogta wakhtiga ku habboon sida saacadaha, halka qaar kalena ay ku cabbiraan daqiiqado ama ilbiriqsi. Sidoo kale, ma sharaxaan sifooyinka kala duwan ama doorsoomayaasha kala duwan ee mudan in aan fiiro gaar ah u leenahay, taas oo naga dhigaysa in aan ku haftay xogta.

Kahor intaanan isku dayin inaan fahamno sifooyinka SMART ee khuseeya, marka hore waa inaan kala saarnaa noocyada ugu waaweyn ee SSD iyo guuldarrooyinka HDD: la saadaalin karo iyo kuwa aan la saadaalin karin^{(SSD and HDD failures: predictable and non-predictable)} .

Guuldarrooyinka la saadaalin karo^{(Predictable failures)} waxaa ka mid ah burburka soo baxa waqtiga oo ay sababaan makaanikada diskka oo khaldan ama waxyeelo soo gaarto dusha diskka haddii ay noqoto hard-disk-yada. Waddooyinka adag ee gobolka, guuldarrooyinka la saadaalin karo waxaa ka mid noqon kara xirashada caadiga ah ee waqtiga ama tiro badan oo isku dayo tirtir ah oo guuldareystay. Dhibaatooyinku^(Problems) way ka sii daraan waqti ka dib, darawalkuna ugu dambeyntii wuu guuldareystaa.

Guuldarrooyinka aan la saadaalin karin^{(Non-predictable failures)} waxaa sababa dhacdooyin kedis ah, kuwaas oo aan ka xusi karno, tusaale ahaan, koronto degdeg ah oo kor u kacday ama waxyeello lama filaan ah oo ku timaada wareegyada gudaha Hard Disk-ga ama darawalka adag. Waxa muhiim ah in la fahmo waa in SMART ay kaliya kaa caawin karto inaad ogaato guul darrooyinka la saadaalin karo^{(S.M.A.R.T. can only help you detect predictable failures)} .

Hadda oo aad leedahay faham aasaasi ah oo ku saabsan waxa SMART uu yahay iyo waxa uu qabanayo, aan aragno sida loo hubiyo heerka SMART ee darawalladaada Windows ka dibna sidoo kale sida loo akhriyo loona tarjumo faahfaahinta SMART :

Sida loo hubiyo heerka SSD iyo HDD SMART

Kumbiyuutarrada iyo aaladaha Windows - ka, sida ugu fudud ee xogta SMART looga akhrin karo Hard Disk-ga ama SSD -ga waa adiga oo isticmaalaya apps gaar ah. Waxaa jira in yar oo halkaas ka baxsan, laakiin qaar badan oo iyaga ka mid ah ayaa si liidata u horumaray ama waa kharash. Dhammaan apps-ka akhrin kara xogta SMART , kan ugu fiican iyo midka aan kugula talineyno inaad isticmaasho waa CrystalDiskInfo .

Habka kale ee ugu fiican ee lagu hubinayo heerka SMART iyo faahfaahinta HDD ama SSD waa in la isticmaalo abka ay bixiso soo saaraha. Tusaale ahaan, inta badan darawalada adag ee gobolka waxaa weheliya abka taageerada kuwaas oo kuu ogolaanaya inaad hubiso macluumaadka iyaga ku saabsan, hubi caafimaadkooda, socodsiiso ogaanshaha, iyo wixii la mid ah. Barnaamijyadan inta badan waxaa ku jira xulashooyin lagu hubinayo heerka SMART .

Habka saddexaad ee lagu hubinayo heerka SMART ee Hard Disk-gaaga ama SSD waxaa bixiya Windows 10 . Ma muujinayso tafaasiil, laakiin waxay kuu sheegi kartaa in heerka SMART ee darawaladaadu ay sax tahay iyo in kale. Si aad u hubiso SMART , fur ^{(open )}Command Prompt oo socodsii amarkan: wmic diskdrive get model, status . Amarka wuxuu soo saarayaa liiska darawallada ku xiran kombuyutarkaaga wuxuuna tusinayaa heerka SMART mid kasta oo iyaga ka mid ah.

Habkan ugu dambeeya ee lagu hubinayo heerka SMART ayaa laga yaabaa inuu yahay habka ugu dhaqsaha badan Windows 10 si loo hubiyo in darawaladaadu ay fashilmeen.

Sida loo maamulo SSD ama HDD SMART test

Haddii aadan ku qanacsanayn akhrinta heerka SMART ee darawalladaada, waxa kale oo aad samayn kartaa SSD ama HDD SMART test. Taasi way fududahay in la sheego intii la sameeyay sababtoo ah waxaad u baahan tahay app gaar ah ujeedadan. Sidaa darteed, waxaan u aragnay in tani ay tahay mawduuc u qalma maqaal gaar ah, kaas oo aad ka heli karto iyada oo loo marayo xiriirkan: Tijaabi HDD-gaaga ama SSD oo hubi xaaladdiisa caafimaad^{(Test your HDD or SSD and check its health status)} .

Sida loo akhriyo SMART qiyamka iyo sifooyinka

Xaaladda caafimaad ee Hard Disk-gu si joogto ah ayaa loo tijaabiyaa waxaana lagula socdaa dareemayaal badan. Qiimayaasha waxaa lagu qiyaasaa isticmaalka algorithms-yada caadiga ah, ka dibna sifooyinka u dhigma ayaa la isku rogay si waafaqsan natiijooyinka.

Barnaamij kasta oo la socodka SMART, waa inaad ku aragto sifooyinka ay ku jiraan ugu yaraan qaar ka mid ah qaybahan:

• Aqoonsiga:^{(Identifier:)} qeexida sifada. Caadiyan waxay leedahay macne caadi ah, waxaana lagu calaamadeeyay tiro u dhaxaysa 1 iyo 250 (tusaale ahaan, 9 waa tirinta awooda^{(Power-on Count)} ). Weli, dhammaan qalabka la socodka diskka iyo tijaabinta waxay bixiyaan magaca iyo sharraxaadda qoraalka ah ee sifada.
• Xadka:^(Threshold:) qiimaha ugu yar ee sifada. Haddii qiimahan la gaaro, markaas darawalkaagu wuxuu ku dhow yahay inuu guuldareysto.
• Qiimaha:^(Value:) qiimaha hadda ee sifada. Algorithm wuxuu xisaabiyaa lambarkan isagoo ku saleysan xogta ceeriin. Dareewalka adag ee cusub waa inuu lahaadaa tiro sare, ugu badnaan aragti (100, 200, ama 253 iyadoo ku xiran soo saaraha), kaas oo hoos u dhacaya inta uu nool yahay.
• Ka ugu xun:^(Worst:) qiimaha ugu yar ee sifo waligeed la diiwaan geliyay.
• Xogta:^(Data:) qiyamka la qiyaasay ee ceyriinka ah waxaa bixiya dareeraha ama miiska. Tani waa xogta uu isticmaalo algorithm-ka uu naqshadeeyay soo saaraha HDD ama SSD . Waxa ku jira waxay ku xidhan tahay sifada iyo cidda samaysay wadista. Isticmaalayaasha joogtada ahi waa inay kan ka boodaan.
• Calanka:^(Flags:) ujeedada sifada. Tan inta badan waxaa dejisa soo saaraha, sidaas darteedna way ku kala duwan tahay darawal ilaa baabuur. Mid kasta oo ka mid ah sifooyinku waa mid muhiim ah oo saadaalin kara guuldarro dhow (tusaale, ID 5 waaxaha la meeleeyay ee la tiriyay), ama tirakoob aan saameyn toos ah ku yeelan heerka (tusaale, ID 174 tirinta korontada lama filaanka ah).

Markaad isku dayeyso inaad fahamto heerka sifada SMART, hubi qiyamka saddexdan goobood: qiimaha, marinka, iyo calanka^{(to understand the status of any S.M.A.R.T. attribute, check the values of these three fields: value, threshold, and flags)} . Sidoo kale, xusuusnow in, inta badan, qiyamka yaryar ay calaamad u yihiin hoos u dhaca kalsoonida^{(smaller values are an indication of a decrease in reliability)} .

Sida loo isticmaalo SMART si loo saadaaliyo guuldarada HDD ama SSD (qiyamyada muhiimka ah si loo hubiyo)

Ma aha dhammaan SMART . sifooyinku waxay muhiim u yihiin saadaasha guuldarada. Labada daraasadood ee aan kor ku soo sheegnay ee ku saabsan heerarka guuldarrooyinka wadida adag iyo ilo kale ayaa isku raacay in caawinta muhiimka ah ee lagu aqoonsanayo darawallada fashilmay ay yihiin:

• Qaybta la meeleeyay waa tirinta^{(Reallocated sector counts)} . Meelayntu waxay dhacdaa marka caqli-galnimada waduhu uu dib u dhigo qaybta dhaawacan, taas oo ay sabab u tahay khaladaadka jilicsan ama adag ee soo noqnoqda, qaybta jireed ee cusub ee ka timaadda kuwa firaaqada ah. Sifadani waxay ka tarjumaysaa tirada jeer ee dib-u-habaynta dhacday. Haddii qiimihiisu kordho, waa calaamad muujinaysa xidhashada HDD ama SSD.

• Tirada Qaybaha La Sugayo^{(Current Pending Sector Count)} . Tani waxay tirinaysaa qaybaha "aan xasiloonayn", taasoo la macno ah kuwa dhaawacan ee leh khaladaadka akhrinta ee sugaya dib u habeyn, nooc ka mid ah nidaamka "tijaabo". Algorithms-yada SMART waxay leeyihiin fahamyo isku dhafan oo ku saabsan sifadan gaarka ah, maadaama ay mararka qaarkood tahay wax aan lagu qanci karin. Weli, waxay bixin kartaa digniin hore oo ku saabsan dhibaatooyinka suurtagalka ah.

• Khaladaad aan la sixi karin oo la soo sheegay^{(Reported Uncorrectable Errors)} . Waa tirinta khaladaadka aan suurtagal ahayn in laga soo kabsado, waana faa'iido leh sababtoo ah waxay u muuqataa inay macno isku mid ah u leedahay dhammaan soosaarayaasha.

• Tirtir Tirsiga Fashilka^{(Erase Fail Count)} . Middaani waa tilmaan aad u wanaagsan oo muujinaysa dhimashada dhicisnimada ah ee waditaanka dawlad adag. Waxay tirisaa tirada isku dayga tirtiridda xogta ee guuldarreystay, qiimaha kor u kacaya wuxuu kuu sheegayaa in xusuusta flash-ka ee gudaha SSD ay ku dhowdahay dhammaadka-nolosheeda.

• Xiro Heerarka Tirada^{(Wear Leveling Count)} . Tani waxay sidoo kale si gaar ah faa'iido u leedahay SSD-yada. Soo-saarayaashu waxay dejiyeen cimriga la filayo ee SSD xogta SMART. Tirada Heerarka Dharka ayaa^{(Wear Leveling Count)} ah qiyaasta caafimaadka waditaankaaga. Waxa lagu xisaabiyaa iyada oo la isticmaalayo algorithm taas oo tixgalinaysa wakhtiga la sii cayimay ee la filayo iyo tirada wareegyada (qor, tirtir, iwm.) ee uu kaydka xusuusta ee kastaa qaban karo ka hor inta aanu gaadhin dhammaadka nolosha.

• Heerkulka diskku^{(Disk temperature)} waa cabbir aad looga dooday. Weli, waxaa loo arkaa in qiyamka ka sarreeya 60°C ay yarayn karaan cimriga HDD ama SSD ayna kordhin karaan suurtogalnimada waxyeellada. Waxaan kugula talineynaa inaad isticmaasho marawaxad si aad u yareyso heerkulka wadayaashaada waxaana rajeyneynaa inay cimrigooda u dheereeyaan.

Midka aan kor ku soo sheegnay SMART . sifooyinku way fududahay in la tarjumo. Haddii aad aragto kor u kaca qiyamkooda, waxaa suurtogal ah in darawalkaagu uu xumaado, markaa waxaa fiican inaad bilowdo inaad dib u soo celiso. Si kastaba ha ahaatee, in kasta oo kuwani yihiin tilmaamayaasha waxtarka leh ee isku halaynta wadista, ha ilaawin in aanay nacasnimo ahayn.

What is SMART and how to use it to predict HDD or SSD failure

A lot of us have experіenced a hard diѕk or an SSD failure. Some of us have even tried to find out more about the reliаbility of hard drives and their hidden prediction function that's part of a technоlogy called SMART. One might argue that SMART iѕ not as reliablе as it does not predict failυre in all cases. This fact is partly true, but the аctυal inner workings of this self-monitoring system are not so simple, so let's examine how SMART works. We're alsо going to show you how to check the HDD SMART status, as well as the solid-state drive SMART status:

What is SMART (HDD & SSD)?

SMART is a system that monitors the internal information of your drive. Its clever name is actually an acronym for Self-Monitoring, Analysis, and Reporting Technology. SMART, also written as S.M.A.R.T., is a technology found inside HDDs and SSDs. It is independent of your operating system, BIOS, or other software.

What does SMART do for HDDs and SSDs?

SMART was invented because computers needed something that could monitor the health state of their hard drives. That means, plainly speaking, that SMART should supposedly be able to tell you if your hard drive or solid-state drive is about to stop working!

How does SMART do that? You might be tempted to think that SMART can magically guess if your drive is healthy. 🙂 What it does is an entirely different story, though. SMART keeps track of a series of variables whose number and type vary from drive to drive, which are indicators of its reliability. If you want to get an in-depth idea of all the SMART attributes, as there are about 50 of them (raw read error rate, spin-up time, reported uncorrectable errors, power-on time, load cycle count, etc.), visit this webpage.

However, know that, apart from some singular attempts (Google, Backblaze), most of the S.M.A.R.T. data is undocumented. The system provides a great deal of internal data. Still, there are many inconsistencies in the statistics because many of the hard drive manufacturers use different definitions and measurements. For example, some manufacturers store power on-time data as hours, while others measure it in minutes or seconds. Also, they don't explain which of the various attributes or variables are worth our attention, making us drown in data.

Before attempting to understand which SMART attributes are relevant, we first have to differentiate between the main types of SSD and HDD failures: predictable and non-predictable.

Predictable failures include the breakdowns that appear in time and are caused by faulty disk mechanics or damages of the disk's surface in the case of hard-disks. For solid-state drives, predictable failures can include normal wear over time or a high number of erasing attempts that have failed. Problems get worse over time, and the drive eventually fails.

Non-predictable failures are caused by sudden events, of which we can mention, for example, sudden power surges or unexpected damage to circuitry inside the hard disk or solid-state drive. What is important to understand is that S.M.A.R.T. can only help you detect predictable failures.

Now that you have a basic understanding of what SMART is and does, let's see how to check the SMART status of your drives from Windows and then also how to read and interpret the SMART details:

How to check SSD and HDD SMART status

On Windows computers and devices, the easiest way to read SMART data from a hard disk or from an SSD is by using specialized apps. There are quite a few out there, but many of them are either poorly developed or cost money. Out of all the apps that can read SMART data, the best and the one that we're recommending that you use is CrystalDiskInfo. It is free, able to read SMART attributes, and it's also one of the few such apps that can get SMART data both from IDE(PATA), SATA, and NVMe drives, as well as from portable drives that are using eSATA, USB, or IEEE 1394.

Another excellent method of checking the SMART status and details of an HDD or SSD is to use the apps provided by its manufacturer. For example, most solid-state drives are accompanied by support apps that let you check information about them, check their health, run diagnostics, and so on. These apps usually include options for checking SMART status.

A third way of checking the SMART status of your hard disk drive or SSD is offered by Windows 10. It doesn't show details, but can tell you whether the SMART status of your drives is OK or not. To check SMART, open Command Prompt and run this command: wmic diskdrive get model, status. The command outputs the list of drives connected to your PC and shows the SMART status for each of them.

This last method to check the SMART status is probably the quickest way in Windows 10 to check whether your drives are failing.

How to run an SSD or HDD SMART test

If you're not satisfied with just reading the SMART status of your drives, you can also run an SSD or HDD SMART test. That is easier said than done because you need a specialized app for this purpose. Accordingly, we considered that this is a subject worthy of a separate article, which you can access via this link: Test your HDD or SSD and check its health status.

How to read SMART values and attributes

The health status of the hard disk is continuously tested and monitored with multiple sensors. The values are measured by the use of typical algorithms, and then the corresponding attributes are tweaked according to the results.

In any SMART monitoring program, you should see attributes that contain at least some of these fields:

• Identifier: the definition of the attribute. It usually has a standard meaning, and it is marked with a number between 1 and 250 (for example, 9 is Power-on Count). Still, all disk monitoring and testing tools provide the name and a textual description of the attribute.
• Threshold: the minimum value for the attribute. If this value is reached, then your drive is about to fail.
• Value: current value of the attribute. The algorithm calculates this number based upon the raw data. A new hard drive should have a high number, the theoretical maximum (100, 200, or 253 depending on the manufacturer), that decreases during its lifetime.
• Worst: the smallest value of the attribute ever recorded.
• Data: raw measured values provided by a sensor or a counter. This is the data used by the algorithm designed by the manufacturer of the HDD or SSD. Its contents depend on the attribute and the maker of the drive. Regular users should skip this one.
• Flags: the purpose of the attribute. This is usually set by the manufacturer and therefore varies from drive to drive. Each of the attributes is either critical and can predict an imminent failure (for example, ID 5 reallocated sectors count), or statistical with no direct effect on status (for example, ID 174 unexpected power loss count).

When trying to understand the status of any S.M.A.R.T. attribute, check the values of these three fields: value, threshold, and flags. Also, remember that, usually, smaller values are an indication of a decrease in reliability.

How to use SMART to predict the failure of an HDD or SSD (essential values to check)

Not all S.M.A.R.T. attributes are critical for failure prediction. The two above mentioned studies on hard drive failure rates and other sources agree that an important help in identifying failing drives are:

• Reallocated sector counts. Reallocation happens when the drive's logic remaps a damaged sector, as a result of recurring soft or hard errors, to a new physical sector from its spare ones. This attribute reflects the number of times a remapping has happened. If its value increases, it's an indication of HDD or SSD wear.

• Current Pending Sector Count. This counts the "unstable" sectors, meaning the damaged ones with read errors that are waiting for a remapping, a kind of "probation" system. S.M.A.R.T. algorithms have mixed understandings about this particular attribute, as it is sometimes unconvincing. Still, it can provide an earlier warning of possible problems.

• Reported Uncorrectable Errors. It is the count of errors that are impossible to recover, and it is useful because it seems to have the same meaning for all manufacturers.

• Erase Fail Count. This one is an excellent indicator of the premature death of a solid-state drive. It counts the number of failed data deletion attempts, and a value that increases tells you that the flash memory inside the SSD is close to its end-of-life.

• Wear Leveling Count. This is also especially useful for SSDs. Manufacturers set the expected lifetime of an SSD in its SMART data. The Wear Leveling Count is an estimation of the health of your drive. It is calculated using an algorithm that takes into account the predefined expected lifetime and the number of cycles (write, erase, etc.) that each memory flash block can perform before reaching its end-of-life.

• Disk temperature is a highly debated parameter. Still, it is considered that values above 60°C can reduce the lifespan of an HDD or SSD and increase the probability of damage. We recommend using a fan to decrease the temperature of your drives and hopefully prolong their life.

The above mentioned S.M.A.R.T. attributes are relatively easy to interpret. If you notice an increase in their values, it is possible that your drive is failing, so you'd better start backing up. However, although these are useful indicators of drive reliability, do not forget that they are not foolproof.

Historical note about SMART

SMART was developed beginning with the year 1992, although you know now that it is included by all modern solid-state drives and hard disk drives. Its history covers an array of names like Predictive Failure Analysis or IntelliSafe and input from all the major hard disk manufacturers: IBM, Seagate, Quantum, Western Digital. Finally, its documentation was featured for the first time in 2004 within the Parallel ATA standard and received regular revisions afterward. The latest one was issued in 2011.

Is there anything else you would like to know about SSD and HDD SMART?

This was our short study on the inner workings of S.M.A.R.T and its abilities to monitor, test, and predict hard disk failures. The main point of view you should remember is that this self-monitoring system can help you review the health status of your HDD. If you want to use this S.M.A.R.T data to see if your own drive has problems, read the articles we recommended in this tutorial. Also, for questions, use the comments form below, and let's discuss.
