Ingabe Ukushayeka KweDrayivu Kuyakhula?
Isingeniso
Ukuphazamiseka kwengcindezi eyinkimbinkimbi kungenye yezinto eziphazamisayo kunazo zonke umuntu angaba nazo ngekhompyutha. Ukuhluleka ukufunda idatha ngaphandle kwe-hard drive kunganikeza ikhompyutha engenalutho. Ngisho noma i-OS ingakwazi ukugijima, idatha ingafinyeleleka noma ingonakali. Indlela kuphela yokubuyisela ekuhlulekeni okunjalo ukubuyisela idatha kusuka kubhekhasethi ukuya kwi-drive entsha nayo yonke isofthiwe efakwe kusukela ekuqaleni. Uma kungekho isipele esitholakalayo, khona-ke idatha ingase ilahleke noma izobiza kakhulu ukuze amasevisi wokutakula abuyele.
Lesi sihloko sizobheka ukuthi yini ebangela ukuhluleka kanzima, uma ukwehluleka kuqhubeka njalo nokuthi yiziphi izinyathelo umuntu angathatha ukuze azame futhi agweme izinkinga uma kwenzeka ukwehluleka.
Ama-Basic Basic Drive
Ngaphambi kokuqonda ukuthi yini engabangela ukwehluleka, kubalulekile ukwazi okuyisisekelo ukuthi isebenza kanjani i-hard drive. I-hard drive ngokuyinhloko idivaysi enkulu enezindaba zokugcina magnetic ezifakwe ezindizeni eziqinile. Lokhu kuvumela idrayivu ukuthi igcine inani elikhulu ledatha elingatholakala futhi libhaliwe ngokushesha kakhulu.
Yonke i-hard drive inezinxenye ezimbalwa eziyinhloko: icala, ukushayela imoto, izindiza, amakhanda okushayela nebhodi lologi. Icala livikela ukushayela endaweni engavaliwe kude nezinhlayiya zothuli. I-motor igxilisa i-drive up ukuze idatha ingakwazi ukufundwa kulezi zinhlamvu. Izindiza zibamba imithombo yamagnetic egcina idatha yangempela. Amakhanda okushayela asetshenziselwa ukufunda nokubhala idatha ezindizeni. Ekugcineni ibhodi legijimi lilawula indlela i-drive engena ngayo futhi ikhulume ngayo yonke uhlelo lwekhompyutha.
Ukuze ubuke ngokuningiliziwe ukuthi iyiphi i-hard drive, ngincoma ukufunda ukuthi "Yeka Ukuthi Ukusebenza Kanzima Kakhulu Kanjani" kusuka ku-How Stuff Works.
Ukuhluleka okuvamile kweDrayivu
Ukuhluleka okuvame kakhulu kwe-hard drive kuyinto okuthiwa ukushaywa kwekhanda. Ukuphahlazeka kwekhanda kunoma yisiphi isici lapho ikhanda lokushayela likwazi ukuthinta isitsha. Uma lokhu kwenzeka, imidiya yamagnetic izokhipha isitsha yikhanda bese inikeza kokubili idatha futhi ikhanda lokushayela lingasebenzi. Akukho ukubuyiswa okuhlanzekile kusuka ekuhlulekeni okunjalo.
Okunye ukwehluleka okuvamile kubangelwa ukungapheleli emithonjeni yamagnetic. Noma yisiphi isikhathi lapho umkhakha on disk ehluleka ukubamba kahle ukuvumelanisa magnetic kuzokwenza ukuthi idatha ingatholakali. Ukushayela ngokujwayelekile kuzoba nokumbalwa kwalezi zinto ezibekwe esikebheni, kodwa zikhonjiswe ngaphandle kokusebenzisa ifomethi yezinga eliphansi kusuka kumenzi. Amafomethi wezinga eliphansi kamuva angenziwa ukuze amake imikhakha njengento engasebenziyo ngakho ngeke isetshenziswe, kodwa lena inqubo ende esula yonke idatha kusuka ku-drive.
Amafoni weselula ayejwayele ukujwayela ama-plateters ahlakazekile. Lokhu kwakungenxa yokuthi izingqwembe eziningi ze-hard drive zenziwa ngilazi futhi zangethusa. Abakhiqizi abaningi banayo noma bashintshe kwezinye izinto zokuvimbela lokhu ukuthi kwenzeke.
Uma kunezinkinga zikagesi ebhodini lologi, idatha ku-drive ingaba engafundiwe noma eyonakele. Lokhu kungenxa yebhodi lologi ehluleka ukuxhumana kahle phakathi kwesistimu yekhompyutha ne-hard drive.
I-MTBF
Ukuze abathengi bathole umbono omuhle wesikhathi sokuphila kwe-hard drive, i-drive yalinganiselwe okuthiwa i-MTBF. Leli gama lisho isikhathi esiphakathi kokuhluleka phakathi kwesikhathi futhi lisetshenziselwa ukumela isikhathi esiphezulu sokuthi amaphesenti angu-50 okushayela angaphumelela ngaphambili kanti amaphesenti angu-50 angaphumeleli ngemuva. Isetshenziselwa ukunikeza umthengi umqondo njengokungathi isilinganiso esilinganiselwe isikhathi idivayisi izosebenza ngayo. Lokhu kwakubhalwe kabanzi ngabakhiqizi kuzo zonke izinkomba zekhompiyutha kodwa eminyakeni yamuva isusiwe kuzo zonke izinkampani zomthengi. Zisabalwe ohlwini lwezinkampani zenkampani yokusebenza kanzima.
Amandla ngokumelene nokuthembeka
Ama-hard drive amakhulu asandise kakhulu eminyakeni embalwa edlule. Lokhu kungenxa yokwanda komthamo wedatha okugcinwe ezindizeni kanye nenani lezinhlamvu ezifakwa ngaphakathi kwesikhala soguquko. Isibonelo, amashayela amaningi asetshenziselwa ukufaka ama-plates amabili noma mhlawumbe amathathu, kodwa abaningi manje bangaba nezinhlamvu ezine eziphelele. Lokhu kwanda kwenani lezingxenye kanye nokwehliswa kwesikhala kuye kwehlise kakhulu ukubekezelelana ukuthi izinkampani zinezikhukhula futhi zandisa inani elingenzeka lokuhluleka.
Ngaphambilini
Ingabe Ukushayela Okungeziwe Kakhulu Ukuhluleka Manje?
Okuningi lokhu kuhlobene nokwakhiwa nokusetshenziswa kwamashayela asebenzayo. Ama-computer amaningi omthengi asetshenziselwa ambalwa amahora ambalwa ngosuku. Lokhu kusho ukuthi amashayeli awazange abe nokusetshenziswa okuqhubekayo okwandisa izici ezifana nokushisa nokuhamba okungabangela ukwehluleka. Amakhompiyutha ajwayelekile kakhulu ekuphileni kwethu futhi asetshenziselwa isikhathi eside. Lokhu kusho ukuthi ukushayela kungenzeka ukuthi kuhluleka kakhulu ngenxa yokusetshenziswa kanzima. Phela, ikhompuyutha isetshenziswe kabili isikhathi eside lapho omunye ngokuvamile ephethe i-hard drive ehluleka kabili ngokushesha. Ngakho lokhu akukwenzanga ngempela ukukala kwezinga lokuhluleka.
Yiqiniso, izici ezifana nokwanda kwedatha kanye nenani lezinhlamvu zingase zibe nomthelela amathuba okuhluleka kanzima. Izingxenye ezengeziwe kanye nokujula kwesibalo semininingwane esitsheni kusho ukuthi kunezinto eziningi ezingase zihambe kahle ngokubangela ukulahlekelwa kwedatha noma ukwehluleka. Ukulwa nalokhu, ubuchwepheshe buye buphuthuka. Amamori angcono, ukwakhiwa kwamakhemikhali wezindaba kanye nezinye izinto kusho ukuthi ukwehluleka okwenzeka njalo ngenxa yalezi zingxenye kuncane kakhulu okwenzekayo.
Ayikho ubufakazi obunzima bokuthi ukwehluleka kwenzeke kaningi. Kusuka kimi ngokwami, angizange ngibone ukwanda kwenani lezimoto ezihlulekayo, kodwa abanye abantu engisebenza nabo baye babona inani elihle lokushayela kumakhompyutha abo banezinkinga. Lokhu kungubufakazi be-anecodotal noma kunjalo.
Iziqinisekiso zingase zibe isibonakaliso esihle sendlela imboni ephathelene ngayo nokuthembeka. Ngemuva kwezinsuku ezimnyama ezizungezile izinkinga ezidabukisayo zeDeskstar, abakhiqizi abaningi babenciphisa iziqinisekiso. Ngaphambi kwalokhu iwaranti evamile yayiyiminyaka emithathu ubude, kodwa izinkampani eziningi zishintsha iminyaka eyi-warranty. Manje izinkampani zivame ukunikeza iziqinisekiso zeminyaka emithathu kuya emihlanu, okusho ukuthi kumele ziqiniseke emotweni yazo njengoba zibiza izindleko.
Yini Ongayenza Ngenkathi Yokuhluleka KweDrayivu?
Inkinga enkulu ngokuhluleka kwe-drive yimalini yedatha engahle ilahleke. Njengoba ukwanda kwenani lamadivaysi edijithali esisebenzisayo kanye nokugcina idatha egcinwe kumasistimu ethu ekhompiyutha, kuphazamiseka kakhulu emiphilweni yethu ukuba ichithe. Idatha yokuphulukiswa emotweni yokulimala ingahle ivela kuma-dollar amaningana kuya ezinkulungwaneni eziningana. Izinsizakalo zokutakula idatha azikho ezingenasici. Ukuphahlazeka kwekhanda kuzosusa imidiya yamagneti esitsheni ekubhubhiseni idatha kuze kube phakade.
Ayikho indlela yangempela yokuvimbela ukuhluleka kwedrayivu noma. Ngisho nomkhiqizo ohlonishwa kakhulu futhi onokwethenjelwa ungaba nedrayivu ehluleka ngokushesha Ngenxa yalokho, kungcono ukuzama futhi uhlele umcimbi ozokwenza ukuthi idrayivu yedatha eyinhloko ihluleke ngokulondoloza idatha. Kunezinhlobo ezahlukene zezindlela zokulondoloza ezitholakalayo ukusebenzisa. Ngamanye amathiphu kulokhu, hlola Okuphathelene Nokugxila kuma-athikili e-Backup Data Backup Data Guide.
Iphuzu elilodwa elilula engiyithandayo ukusikisela kubantu kuyimishini yokushayela ephathekayo. Ayisabizi futhi ngenxa yokusetshenziswa kwawo okulinganiselwe, cishe ayinakuhluleka uma egcinwe kahle futhi ephethwe kahle. Ukushayela okunamandla kwangaphandle kuyatholakala ezinkambeni ezifanayo ngokufanayo njengoba ideskithophu iqhuba ngoba ngokuvamile isebenzisa amashayela afanayo. Isihluthulelo ukusebenzisa kuphela idrayivu uma usekela idatha noma uyibuyisela. Lokhu kunciphisa isikhathi esisetshenziswa ngaso bese kunciphisa ithuba lokuhluleka.
Enye indlela evulekile kubasebenzisi ukwakha i-PC yedeskithophu ngenguqulo ye-RAID ene-redundancy yedatha eyakhiwe kuyo. Ifomu elula ye-RAID yokusetha i-RAID 1 noma i-mirroring. Lokhu kudinga isilawuli se-RAID kanye namashayela amabili asebenzayo ngokulinganayo. Yonke idatha ebhaliswe ku-drive eyodwa ihlolwe ngokuzenzakalelayo komunye. Uma kwenzeka ukwehluleka kwedrayivu eyodwa, i-drive yesibili izohlala idatha njalo. Ukuze uthole ulwazi oluthe xaxa mayelana ne-RAID, hlola ukuthi yini Engikushicilelayo .
