Kukho ulwazi oluninzi kwi-Intanethi malunga ne-SMART kunye neempawu zophawu. Kodwa andizange ndihlangabezane nakuphi na ukukhankanywa kweengongoma ezininzi ezibalulekileyo endizaziyo malunga nabantu ababandakanyekayo kwisifundo sokugcina imithombo yeendaba.
Xa ndaphinda ndaxelela umhlobo wam malunga nokuba kutheni ufundo lwe-SMART kufuneka lungathenjwa ngaphandle kwemiqathango kwaye kutheni kungcono ukungasebenzisi "iimonitha ezi-SMART" ngalo lonke ixesha, umbono weza kum wokuba ndibhale phantsi amagama athethwa ngendlela iseti yezi zinto zineengcaciso. Ukubonelela ngamakhonkco endaweni yokubalisa kwakhona ixesha ngalinye. Kwaye ukwenza ifumaneke kubaphulaphuli ababanzi.
1) Iinkqubo zokujonga ngokuzenzekelayo iimpawu ze-SMART kufuneka zisetyenziswe ngononophelo olukhulu.
Into oyaziyo njengeempawu ze-SMART azigcinwa sele zenziwe, kodwa ziveliswa oko nje uzicele. Zibalwe ngokusekelwe kwizibalo zangaphakathi eziqokelelwe kwaye zisetyenziswe yi-firmware ye-drive ngexesha lokusebenza.
Isixhobo asiyifuni enye yale datha ukunika umsebenzi osisiseko. Kwaye ayigcinwa, kodwa iveliswa ngalo lonke ixesha ifunwa. Ngoko ke, xa isicelo seempawu ze-SMART senzeka, i-firmware iqalisa inani elikhulu leenkqubo ezifunekayo ukufumana idatha engekhoyo.
Kodwa ezi nkqubo azihambelani kakuhle neenkqubo ezenziwayo xa i-drive ilayishwe ngemisebenzi yokufunda-bhala.
Kwihlabathi elifanelekileyo, oku akufanele kubangele naziphi na iingxaki. Kodwa enyanisweni, i-hard drive firmware ibhalwe ngabantu abaqhelekileyo. Ngubani onokwenza kwaye enze iimpazamo. Ke ngoko, ukuba ubuza ngeempawu ze-SMART ngelixa isixhobo siqhuba umsebenzi wokufunda-bhala, ukuba nokwenzeka kwento engahambi kakuhle konyuka kakhulu. Umzekelo, idatha kwibuffer yokufunda okanye yokubhala yomsebenzisi iya konakaliswa.
Inkcazo malunga nokunyuka kweengozi ayisosiphelo sethiyori, kodwa imbono ebonakalayo. Ngokomzekelo, kukho i-bug eyaziwayo eyenzeka kwi-firmware ye-HDD Samsung 103UI, apho idatha yomsebenzisi yonakaliswa ngexesha lenkqubo yokucela iimpawu ze-SMART.
Ngoko ke, musa ukuqwalasela ujongo oluzenzekelayo lweempawu ze-SMART. Ngaphandle kokuba uyazi ngokuqinisekileyo ukuba umyalelo we-cache gung (i-Flush Cache) ukhutshiwe phambi koku. Okanye, ukuba awukwazi ukwenza ngaphandle kwayo, qwalasela iskena ukuba siqhube ngokunqabileyo kangangoko. Kwiinkqubo ezininzi zokubeka iliso, ixesha elimiselweyo phakathi kweetshekhi malunga nemizuzu eyi-10. Oku kuxhaphake kakhulu. Ngokufanayo, olo vavanyo alulonyango lokusilela okungalindelekanga kwidisk (i-panacea lugcino kuphela). Kanye ngosuku - ndicinga ukuba kwanele.
Ubushushu obubuzayo abuzibalisi iinkqubo zokubala kwaye lunokwenziwa rhoqo. Ngenxa yokuba xa iphunyezwe ngokuchanekileyo, oku kwenziwa nge-SCT protocol. Nge-SCT, kuphela oko sele kwaziwa okunikwayo. Le datha ihlaziywa ngokuzenzekelayo ngasemva.
I-2) Idatha yophawu lwe-SMART ihlala ingathembekanga.
I-firmware ye-hard drive ikubonisa into ecinga ukuba kufuneka ikubonise yona, kungekhona into eyenzekayo ngokwenene. Owona mzekelo ucacileyo ngumba we-5, inani lamacandelo abelwe kwakhona. Iingcali zokubuyisela idatha ziyazi kakuhle ukuba i-hard drive ingabonisa inani elingu-zero lokwabiwa kwakhona kwimpawu yesihlanu, nangona zikhona kwaye ziqhubeka zivela.
Ndibuze umbuzo kwingcali efunda ii-hard drives kwaye ivavanye i-firmware yazo. Ndabuza ukuba yintoni umgaqo apho i-firmware yesixhobo ithatha isigqibo sokuba ngoku kuyimfuneko ukufihla inyaniso yokwabiwa kwakhona kwecandelo, kodwa ngoku unokuthetha ngayo ngeempawu ze-SMART.
Waphendula wathi akukho mgaqo jikelele ngokweziphi izixhobo ezibonisa okanye zifihla umfanekiso wangempela. Kwaye ingqiqo yabadwelisi ababhala i-firmware kwii-hard drives ngamanye amaxesha ibonakala ingaqhelekanga kakhulu. Ukufunda i-firmware yeemodeli ezahlukeneyo, wabona ukuba ngokuqhelekileyo isigqibo "sokufihla okanye ukubonisa" senziwe ngokusekelwe kwiseti yeeparitha ezingacacanga ngokubanzi ukuba zihlobene njani omnye nomnye kunye nomthombo oseleyo we-hard drive.
3) Ukutolikwa kwezalathi ze-SMART kuxhomekeke kumthengisi.
Ngokomzekelo, kwii-Seagates akufanele unikele ingqalelo kwixabiso "elibi" leempawu ze-1 kunye ne-7, ukuba nje ezinye ziqhelekileyo. Kwiidiski ezivela kulo menzi, amaxabiso azo apheleleyo anokonyuka ngexesha lokusetyenziswa okuqhelekileyo.
Ukuvavanya imeko kunye nobomi obuseleyo be-hard drive, okokuqala kucetyiswa ukuba ubeke ingqalelo kwiiparameters 5, 196, 197, 198. Ngaphezu koko, kunengqiqo ukugxila kumanani apheleleyo, aluhlaza, kwaye kungekhona kulawo anikiweyo. . Ukunyanzeliswa kweempawu kunokwenziwa ngeendlela ezingabonakaliyo, ezahlukeneyo kwii-algorithms ezahlukeneyo kunye ne-firmware.
Ngokubanzi, phakathi kweengcali zokugcina idatha, xa zithetha ngexabiso leempawu, ngokuqhelekileyo zithetha ixabiso elipheleleyo.
