Ngaba Ukuqhuba Ukungaphumeleli Kukunyuka?
Intshayelelo
Ukutshatyalaliswa kweDisk drive kunesinye sezihlandlo ezibuhlungu kakhulu ezinokuba nazo ngekhompyutha. Ukungakwazi ukufunda idatha kwi-hard drive kungenza ikhompyutha ingenanto. Nangona i-OS ingaqhuba, idatha ingenakufikeleleka okanye ingonakaliswe. Indlela yodwa yokubuyisela ekungaphumeleli kukuba ukubuyisela idatha kwi-backup kwi-drive entsha kunye nayo yonke isofthiwe efakwe ukususela ekuqaleni. Ukuba akukho ncediso ekhoyo, ngoko idatha ilahlekile okanye iya kuba neendleko ezininzi kwiinkonzo zokubuyisela ukufumana kwakhona.
Eli nqaku liza kujonga oko kubangela ukungaphumeleli komqhubi wecala, ukuba ukuhluleka kuya kudla ngokuphindaphindiweyo kwaye yeyiphi inyathelo umntu anokuthatha ukuzama ukukhusela iingxaki xa kwenzeka ukungaphumeleli.
Iisiseko zeDrive Drive
Ngaphambi kokuqonda oko kunokubangela ukungaphumeleli, kubalulekile ukwazi izizathu zendlela i-hard drive isebenza ngayo. I-hard drive iyisisiseko esikhulu esinezixhobo zokugcina ezikumgangatho ogqityiweyo. Oku kuvumela i-drive ukuba igcine inani elikhulu leenkcukacha ezingasifumana kwaye libhalwa ngokukhawuleza.
Yonke i-drive ekhuni iqulethwe ngamacandelo amanani athile: ityala, i-drive motor, i-platters, iinqununu zokuqhuba kunye nebhodi yamagama. Icala linika ukhuseleko kwi-drive kwindawo engqinileyo ngaphandle kweengqungquthela zothuli. Umqhubi uphepha umqhubi ukwenzela ukuba idatha ikwazi ukufundwa kwiintlanzi. Izicwangciso zibamba imithombo yamagnetic egcina idatha yangempela. Iintloko zogxininisa zisetyenziselwa ukufunda nokubhalwa kwedata kwiintlanzi. Ekugqibeleni ibhodi yeengcamango ilawula indlela i-drive edibanisa ngayo kunye neentetho kuzo zonke iinkqubo zekhompyutha.
Ukujonga ngokubanzi kwinqanaba le-hard drive, ndincoma ukufunda "Ukusebenza Kanzima Kowomsebenzi" ukususela njani Iindlela eziSebenza ngayo.
Ukungasebenzi kweDrive ngokuqhelekileyo
Ukungaphumeleli okuqhelekileyo kwidiski ekhuni yinto ebizwa ngokuba yi-head crash. Ukuqhuma kwentloko naliphi na umzekelo apho ikhanda lokuqhuba lilawula ukuchukumisa isitya. Xa oku kwenzeka, i-media magnetic iya kukhishwa kwi-platter yintloko kwaye unike zombini idatha kunye nentloko yokuqhuba ingasebenzi. Akukho kuhlaziywa okucocekileyo kweso siphene.
Olunye ulwahlulo oluqhelekileyo lubangelwa kukungapheleli kwimidiya yamagnetic. Naliphi na ixesha apho icandelo kwi disk ehluleka ukubamba ngokufanelekileyo ukulungelelaniswa kwamagnethi kuya kwenza ukuba idatha ingakwazi ukufikelela. Ukuqhuba ngokuqhelekileyo kuya kuba neminye yalezi zikhoyo kwi-platter, kodwa ziphawulwe ngaphandle kokusetyenziswa kwefomathi yezantsi ukusuka kumenzi. Iifom zezinga eliphantsi ezisezantsi ziyakwenziwa ukwenzela ukuba amake amacandelo angenakulungiswa ukuze angasetyenziswanga, kodwa le yinkqubo ende eyacima yonke idatha esuka kwi-drive.
Iifowuni zefowuni zazixhomekeke kwiintsimbi ezityhutyhileyo. Oku kwakungenxa yokuba ininzi yeenqwelo zokuqhuba i-hard drive zenziwa ngeglasi kwaye zandimangalisa. Abaninzi abenzi benzi banokutshintshela kwezinye izinto ukukhusela oku kungenzeki.
Ukuba kukho iingxaki zombane kwibhodi yeempawu, idatha kwi-drive ingaba ingafundwanga okanye iwonakalise. Oku kubangelwe kwibhodi yelogi engakwazi ukuthetha ngokufanelekileyo phakathi kwenkqubo yekhompyutha kunye ne-drive drive.
MTBF
Ukuze abathengi bafumane ingcamango efanelekileyo yokuphila kwe-drive drive, i-drive yalinganiswa ngento ethi MTBF. Eli gama limela ixesha eliphakathi kwexesha lokungaphumeleli kwaye lisetyenziselwa ukumela ubude bexesha apho ama-50 eepesenti yokuqhuba angaphumeleli ngaphambili kwaye ama-50 ekhulwini aya kusweleka emva. Isetyenziselwa ukunika ingcamango umthengi ngokumalunga nomyinge wexesha eliza kusebenza kuyo. Oku kwakuboniswe ngabavelisi kuzo zonke iikhomputha kodwa kwiminyaka yakutshanje isusiwe kuwo wonke umsebenzisi. Zisahlongozwa kwiinkampani ezinzima zokuqhuba iiklasi.
Ukwazi ukuxhomekeka
Ubunzima bokuqhuba umqhubi obunzima buye bunyuka kakhulu kwiminyaka embalwa edlulileyo. Oku kubangelwa ukwanda kobuninzi beenkcukacha ezigcinwe kwiiseti kunye nenani leenqwelo ezibekwe ngaphakathi kwimeko yecala. Ngokomzekelo, ezininzi iimoto ezisetyenziselwa ukubonisa ezimbini okanye mhlawumbi izitya ezintathu, kodwa ezininzi ngoku zinokufikelela kwiine-plates ezipheleleyo. Olu konyuka kwinani leenxalenye kunye nokunciphisa isikhala kuye kwanciphisa kakhulu ukunyamezela okubakhoyo kunye nokunyusa inani lokungaphumeleli.
Ngaphambili
Ngaba iiMoto eziTyekelekile ngakumbi ukusilela ngoku?
Ininzi yale nto ifana nokwakhiwa kunye nokusetyenziswa kweemoto ezinzima. Iikhomputha ezininzi zeethengi zisetyenziselwa ezimbalwa iiyure ezimbalwa ngosuku. Oku kuthetha ukuba ii-drive azizange zisebenzise ixesha elide lokusetyenziswa okuqhubekayo ezandisa izinto ezifana nokushisa kunye nokunyakaza okungakhokelela ekusileleni. Iikhomputha zixhaphake kakhulu kubomi bethu kwaye zisetyenziselwa ixesha elide. Oku kuthetha ukuba ii-drivers cishe zihluleka ngokuphindaphindiweyo ngenxa yokusetyenziswa kona. Emva koko, ikhompyutheni isetyenziswe kabini ixesha elide elinye liza kuba ne-hard drive lishaye kabini ngokukhawuleza. Ngoko oku akukwenzanga ukwandisa izinga lokungaphumeleli.
Ngokuqinisekileyo, izinto ezinjengokwanda kwenkcazelo yolwazi kunye nenani leenqwelo zingaba negalelo lokungaphumeleli kwe-drive drive. Ezinye iindawo kunye nobunzima beenkcukacha kwiintlanzi kuthetha ukuba kukho ezinye izinto ezinokuthi zingenzi kakuhle ukulahleka kwedatha okanye ukuhluleka. Ukukhusela oku, kodwa ubugcisa buye buphucula. Iimodorobho ezingcono, ukwakhiwa kweekhemikhali zendaba kunye nezinye izinto zithetha ukuba ukungaphumeleli okwakwenzeka kwenzeka ngenxa yalezi zingxenye akunakwenzeka ukuba kwenzeke.
Akukho bubungqina obunzima bokuthi ukungaphumeleli kwenzeka ngokuphindaphindiweyo. Ukusuka kum namava, ndibonanga ukwanda kweenombolo zokuqhuba, kodwa abanye abantu endisebenza nabo baye babona inani elifanelekileyo lokuqhuba kwiikhomputha zabo baneengxaki. Oku kubungqina bokuba unecodotal.
Iimqinisekiso zingabonakalisa isibonakaliso sendlela umboniso ojongene ngayo nokuthembeka. Emva kweentsuku ezimnyama ezijikeleze iingxaki ezinzulu zeDeskstar, abaninzi abavelisi bekunciphisa iimbopheleleko. Ngaphambi koko iwaranti yesiqhelo yayiminyaka emithathu ubude, kodwa inkampani ezininzi zatshintshela kwiminyaka emithathu yemigunya. Ngoku iinkampani zibonelela ngeminyaka emithathu ukuya kweyimihlanu imirhurenti emininzi ebonisa ukuba kufuneka ukuba nethemba kwiimoto zabo njengoko zindleko zokuthatha indawo.
Yintoni enokuyenza kwiNkundla yokuPhathala kweDrayivu?
Ingxaki enkulu kunokungaphumeleli kwe-drive kuyimali yedatha ekhoyo. Ngokunyuka kwenani lamadivaysi yedijithali esisisebenzisayo kwaye igalelo eligcinwe kwiinkqubo zethu zekhompyutheni, kukuphazamisa ngakumbi kwimpilo yethu ukuba ibhujiswe. Idatha yokuphulukana kwiimoto ezonakalisiweyo zingahamba ukusuka kumawaka angama-dollar ukuya kumawaka amaninzi. Iinkonzo zokubuyiswa kwedatha azinasiphina. Ukuqhutyelwa kwentloko kuya kushenxisa i-media magnetic kwisitya esitshabalalisa idatha ngonaphakade.
Akukho ndlela yangempela yokukhusela ukungaphumeleli kwe-drive nokuba. Ngona uphawu oluthembekileyo noluthembekileyo lunokuba ne-drive engaphumeleli ngokukhawuleza Ngenxa yoko, kukulungele ukuzama nokucwangcisa isiganeko esiza kubangela ukuba i-data yedayibrari idityaniswe nge-backups yedatha. Kukho uluhlu olubanzi lweendlela zokulondoloza ezisetyenziswayo. Ngamanye amathiphu kulokhu, khangela i-About Focus kwi-I-PC Inkxaso ye-PC Support articles.
Esinye isicatshulwa esilula ndiyathanda ukusikisela kubantu ngabaqhubi abathintekayo. Zinto ezingabizi kakhulu kwaye ngenxa yokusetyenziswa kwazo okuncinci, ayinakukwazi ukuhluleka xa zigcinwe kakuhle kwaye ziphathwa. Ukuqhutshwa kwangaphandle kwezinto ezikhoyo zifumaneka kwizinto ezifanayo ngokufanayo njengoko idesksi ziqhuba ngenxa yokuba zivame ukusebenzisa izixhobo ezifanayo. Isibalulekileyo kukusebenzisa kuphela idrayivu xa uxhasa idatha okanye uyibuyisela. Oku kunciphisa inani lexesha elisetyenzisiweyo kwaye kunciphise ithuba lokungaphumeleli.
Enye indlela evulekileyo kubasebenzisi kukukwakha iPC desktop kunye ne-RAID ene-redundancy yedatha eyakhelwe kuyo. Ifomu elula ye-RAID yokusetha i-RAID 1 okanye i-mirroring. Oku kufuna umlawuli we-RAID kunye nezixhobo ezinzima ezilinganayo. Yonke idatha ebhaliweyo kwi-drive eyodwa ilandiswa ngokuzenzekelayo kwenye. Xa kwenzeka ukungaphumeleli komqhubi omnye, i-drive yesibili iya kuhlala idatha. Ukufumana ulwazi oluthe xaxa malunga ne-RAID, khangela i-My What is Raid article.
