Pali zambiri pa intaneti zokhudzana ndi SMART ndi makhalidwe. Koma sindinakumanepo ndi kutchulidwa kulikonse kwa mfundo zingapo zofunika zomwe ndikudziwa kuchokera kwa anthu omwe akuchita nawo kafukufuku wosungirako zinthu.
Pamene ndinali kuuzanso mnzanga za chifukwa chake kuwerenga kwa SMART sikuyenera kudaliridwa mopanda malire komanso chifukwa chake ndibwino kuti musagwiritse ntchito "ma SMART monitors" nthawi zonse, lingaliro linabwera kwa ine kuti ndilembe mawu olankhulidwa ngati mawonekedwe a SMART. seti la mfundozi ndi mafotokozedwe. Kupereka maulalo m'malo mobwereza nthawi iliyonse. Ndipo kuti izipezeka kwa anthu ambiri.
1) Mapulogalamu owunikira okha mawonekedwe a SMART ayenera kugwiritsidwa ntchito mosamala kwambiri.
Zomwe mumadziwa ngati SMART sizimasungidwa zokonzeka, koma zimapangidwa mukangopempha. Amawerengedwa kutengera ziwerengero zamkati zomwe zasonkhanitsidwa ndikugwiritsidwa ntchito ndi firmware ya drive panthawi yogwira ntchito.
Chipangizochi sichifuna zina mwazinthuzi kuti zipereke magwiridwe antchito. Ndipo sichisungidwa, koma chimapangidwa nthawi iliyonse yomwe ikufunika. Chifukwa chake, pempho la mawonekedwe a SMART likachitika, firmware imayambitsa njira zambiri zomwe zimafunikira kuti mupeze zomwe zikusowa.
Koma njirazi sizigwirizana bwino ndi njira zomwe zimachitidwa pamene galimotoyo yadzaza ndi ntchito zolembera.
M'dziko labwino, izi siziyenera kuyambitsa mavuto. Koma kwenikweni, hard drive firmware imalembedwa ndi anthu wamba. Yemwe angathe ndi kulakwitsa. Chifukwa chake, ngati mufunsa za SMART pomwe chipangizocho chikugwira ntchito yowerenga-lemba, mwayi woti chinachake sichikuyenda bwino umawonjezeka kwambiri. Mwachitsanzo, data mu buffer yowerengera kapena kulemba ya wogwiritsa ntchito iwonongeka.
Mawu onena za kuopsa kochulukirachulukira sizongopeka chabe, koma ndikuwona bwino. Mwachitsanzo, pali cholakwika chodziwika chomwe chidachitika mu firmware ya HDD Samsung 103UI, pomwe chidziwitso cha ogwiritsa ntchito chidawonongeka panthawi yofunsira ma SMART.
Chifukwa chake, musakonze zowunikira zokha za SMART. Pokhapokha mutadziwa motsimikiza kuti cache flush command (Flush Cache) yaperekedwa izi zisanachitike. Kapena, ngati simungathe kuchita popanda, sinthani sikaniyo kuti igwire ntchito kawirikawiri momwe mungathere. M'mapulogalamu ambiri owunika, nthawi yokhazikika pakati pa macheke ndi pafupifupi mphindi 10. Izi ndizofala kwambiri. Momwemonso, kuwunika kotereku sikuthetsa vuto la kulephera kosayembekezereka kwa disk (panacea ndikusunga kokha). Kamodzi patsiku - ndikuganiza kuti ndizokwanira.
Kutentha kofunsa sikuyambitsa mawerengedwe amalingaliro ndipo kumatha kuchitika pafupipafupi. Chifukwa zikagwiritsidwa ntchito moyenera, izi zimachitika kudzera mu protocol ya SCT. Kupyolera mu SCT, zomwe zimadziwika kale zimaperekedwa. Izi zimasinthidwa zokha kumbuyo.
2) Zambiri zamtundu wa SMART nthawi zambiri zimakhala zosadalirika.
Firmware ya hard drive imakuwonetsani zomwe ikuganiza kuti ikuyenera kukuwonetsani, osati zomwe zikuchitikadi. Chitsanzo chodziwika bwino ndi chikhalidwe cha 5, chiwerengero cha magawo omwe adagawidwanso. Data kuchira akatswiri akudziwa bwino kuti chosungira akhoza kusonyeza ziro chiwerengero cha reallocations mu chikhalidwe chachisanu, ngakhale alipo ndi kupitiriza kuonekera.
Ndinafunsa funso kwa katswiri yemwe amaphunzira ma hard drive ndikuwunika firmware yawo. Ndidafunsa kuti ndi mfundo iti yomwe firmware ya chipangizocho imasankha kuti tsopano ndikofunikira kubisa mfundo yosinthira magawo, koma tsopano mutha kuyankhula za izi kudzera muzochita za SMART.
Iye anayankha kuti palibe lamulo lachidziwitso malinga ndi zipangizo zomwe zimasonyeza kapena kubisa chithunzi chenichenicho. Ndipo malingaliro a opanga mapulogalamu omwe amalemba firmware kwa hard drive nthawi zina amawoneka achilendo kwambiri. Powerenga firmware yamitundu yosiyanasiyana, adawona kuti nthawi zambiri lingaliro la "kubisa kapena kuwonetsa" limapangidwa potengera magawo omwe nthawi zambiri sadziwika bwino momwe amalumikizirana wina ndi mnzake komanso kuzinthu zotsalira za hard drive.
3) Kutanthauzira kwa zizindikiro za SMART ndizosiyana ndi ogulitsa.
Mwachitsanzo, pa Seagates sayenera kulabadira "zoyipa" yaiwisi makhalidwe 1 ndi 7, malinga ngati zina zonse ndi zachilendo. Pa ma disks ochokera kwa wopanga uyu, mayendedwe awo amtheradi amatha kuwonjezeka pakagwiritsidwe ntchito wamba.
Kuti muwone momwe zinthu ziliri ndi moyo wotsalira wa hard drive, choyamba tikulimbikitsidwa kumvetsera magawo 5, 196, 197, 198. Komanso, n'zomveka kuyang'ana pazitsulo zopanda pake, zopanda pake, osati pa zomwe zapatsidwa. . Kukakamizika kwa zikhumbo kungathe kuchitidwa m'njira zosaonekera, mosiyana ndi ma algorithms osiyanasiyana ndi firmware.
Kawirikawiri, pakati pa akatswiri osungira deta, akamalankhula za mtengo wa chikhalidwe, nthawi zambiri amatanthauza mtengo weniweni.
