Incazelo yezinkampani zeDiski nobukhulu bokulungiswa kwemikhakha ewonakele
Imikhakha isigaba esinqunyiwe se- hard disk drive , i-disc optical, i-floppy disk, i- flash drive , noma uhlobo oluthile lwesitoreji.
Umkhakha ungathunyelwa futhi njengomkhakha we- disk noma, ngokujwayelekile, ibhlokhi.
Yini Eyahlukene Yezinkampani Zomkhakha?
Yonke imikhakha ithatha indawo yangasese kudivayisi yokugcina futhi ivame ukuhlanganiswa izingxenye ezintathu: inhloko yomkhakha, ikhodi yokulungisa amaphutha (ECC), kanye nendawo egcina ngempela idatha.
Ngokuvamile, ingxenye eyodwa yedrayivu yedisk diski noma i-floppy disk ingabamba ama-bytes angu-512 olwazi. Le nqubo yasungulwa ngo-1956.
Ngawo-1970, ubukhulu obukhulu njengama-bytes angu-1024 kanye no-2048 aqaliswa ukuze athole amandla okugcina amakhulu. Omunye umkhakha we-disc optical ngokuvamile ungabamba ama-bytes angu-2048.
Ngonyaka ka-2007, abakhiqizi baqala ukusebenzisa ama-drives aseqophelweni eliphezulu afaka ama-bytes angu-4096 ngomkhakha ngamunye ukuze bakhulise usayizi wesigaba kanye nokuthuthukisa iphutha lokulungisa. Le nqubo isetshenziswe kusukela ngo-2011 njengosayizi wesigaba omusha wezinkinobho ezinzima zanamuhla.
Lo mdahluko usayizi wesigaba akusho lutho ngalutho umahluko phakathi kwamashayela asebenzayo kanye nama-optical disc. Ngokuvamile kuyinamba yemikhakha etholakalayo kwi-drive noma i-disc enquma amandla.
Ama-Disk Sectors kanye nokwabiwa Kwama Unit
Uma ufometha i-hard drive, noma usebenzisa ama-Windows 'amathuluzi ayisisekelo noma ngekhomishini yokuhlukanisa i-disk yamahhala , uyakwazi ukuchaza usayizi weyunithi yokwabiwa ngokwezifiso (AUS). Lokhu kubaluleke kakhulu ukutshela uhlelo lwefayela ukuthi ingxenye encane kunazo zonke yediski engasetshenziselwa ukugcina idatha yiyona.
Isibonelo, ku-Windows, ungakhetha ukufometha i-hard drive kunoma yiliphi lamasayizi alandelayo: 512, 1024, 2048, 4096, noma ama-byte angu-8192, noma angu-16, 32, noma ama-kilobytes angu-64.
Ake sithi unamafayela wedokhumenti angu-1 MB (1,000,000 byte). Ungagcina le dokhumenti ngento efana ne-floppy disk egcina u-512 bytes kolwazi kumkhakha ngamunye, noma kwi-hard drive enezintambo ezingu-4096 kumkhakha. Akubalulekile ukuthi umkhakha ngamunye ukhulu kangakanani, kodwa ukuthi idivayisi yonke ikhulu kangakanani.
Umehluko kuphela phakathi kwedivaysi ozokwabiwa kobukhulu obungu-512 bytes, kanti leyo engama-4096 byte (noma 1024, 2048, njll), ukuthi ifayela le-1 MB kufanele lihlukaniswe nakwezinye izingxenye ze-disk kunokuba kudivayisi ye-4096. Lokhu kungenxa yokuthi u-512 uncane kune-4096, okusho ukuthi "izingcezu" ezingaphansi kwefayela zingaba khona emkhakheni ngamunye.
Kulesi sibonelo, uma idokhumenti engu-1 MB ihlelwe futhi manje iba yifayela le-5 MB, lokho kwanda ngobukhulu be-4 MB. Uma ifayela ligcinwe ku-drive ngokusebenzisa usayizi we-unit unit elinikezwa ngu-512 byte, izingcezu zaleli fayela le-4 MB zizosabalalisa kulo lonke i-hard drive zibe kwezinye izingxenye, mhlawumbe emikhakheni eqhubekayo kude neqembu lokuqala lemikhakha ephethe 1 MB yokuqala , okwenza okuthiwa ukuhlukaniswa .
Kodwa-ke, usebenzisa isibonelo esifanayo njengangaphambili kepha ngobukhulu besilinganiso se-4096 byte unit unit, izindawo ezincane disk izobamba 4 MB idatha (ngoba ngamunye block block ubukhulu), ngaleyo ndlela kudala iqoqo imikhakha esondelene ndawonye, ​​ukunciphisa amathuba okuthi ukuhlukaniswa kuzokwenzeka.
Ngamanye amazwi, i-AUS enkulu ibonisa ukuthi amafayili cishe angasondelana ndawonye ku-hard drive, okuzophumela ekufinyeleleni okusheshayo kwediski nokusebenza komsebenzi jikelele wekhompyutha.
Ukushintsha Usayizi Wokwabiwa Kweyunithi YeDisk
I-Windows XP kanye nezinhlelo zokusebenza ezintsha ze-Windows zingasebenzisa umyalo we- fsutil ukuze ubone usayizi weqoqo we-hard drive ekhona. Isibonelo, ukungena ku-fsinfo ntfsinfo c: kumshini wokulawula umyalo njengo- Command Prompt uzothola usayizi weqoqo weC: drive.
Akuvamile kakhulu ukushintsha usayizi weyunithi we-unit of drive. I-Microsoft inezibhebhe ezibonisa ubukhulu beqoqo leqoqo lezinhlelo zefayela le- NTFS , FAT , ne-exFAT ezihumulweni ezahlukene ze-Windows. Isibonelo, i-AUS ezenzakalelayo ingu-4 KB (4096 bytes) yezinkinobho ezinzima ezifakwe nge-NTFS.
Uma ufuna ukushintsha usayizi weqoqo lwedatha ye disk, lungenziwa ku-Windows uma kufometha i-hard drive kodwa izinhlelo zokuphatha i-disk ezivela kubakhi beqembu lesithathu zingakwenza futhi.
Nakuba kungenzeka ukuthi kulula kakhulu ukusebenzisa ithuluzi lokufometha elakhelwe ku-Windows, lolu hlu lwamathuluzi wokuhlukanisa i-Free Disk lufaka izinhlelo eziningana zamahhala ezingenza into efanayo. Iningi linikeza okukhethwa kukho usayizi weyunithi ngaphezulu kune-Windows.
Indlela Yokulungisa Imikhuba Emibi
I-hard drive eyonakaliswe ngokwemvelo ivame ukuchaza imikhakha ewonakele emzimbeni we-platter drive ngenkathi inkohlakalo nezinye izinhlobo zomonakalo zingenzeka futhi.
Omunye umkhakha okhungathekile wokuba nezinkinga yi- sector boot . Uma le nkampani inenkinga, ivumela uhlelo lokusebenza ukuthi lungakwazi ukuqala!
Nakuba imikhakha ye-disk ingahle yonakaliswe, ngokuvamile kuvame ukuyilungisa ngaphandle kokusebenza kwesofthiwe. Bheka Ngingahlola kanjani I-Hard Drive Yami Yezinkinga? ukuze uthole ulwazi oluthe xaxa ngezinhlelo ezingakwazi ukubona, futhi zivame ukulungisa noma ukubeka uphawu olubi, ukuxuba imikhakha enezinkinga.
Kungase kudingeke uthole i-hard drive entsha uma kunemikhakha eminingi embi kakhulu. Bheka Ngifaka Kanjani I-Hard Drive? ukuze uthole usizo esikhundleni senqola ezinzima ezinhlotsheni ezahlukene zekhompyutha.
Qaphela: Ngenxa nje yokuthi unekhompyutha encane, noma ngisho nedrayivu eyinkimbinkimbi eyenza umsindo , akusho ukuthi kukhona okungahambi kahle ngokomzimba emikhakheni yediski. Uma usacabanga ukuthi kukhona okungahambi kahle nge-hard drive ngisho nangemva kokusebenzisa ukuhlolwa kwe-hard drive, cabanga ukuskena ikhompyutha yakho kuma-virus noma ukulandela ezinye izinkinga.
Ulwazi oluthe xaxa kuma-Disk Sector
Imikhakha eseduze nendawo ngaphandle kwe disk inamandla kunalabo abasondelene nendawo, kodwa futhi banesibalo esincane esincane. Ngenxa yalokhu, okuthiwa indawo ye-bit bit yokuqopha isetshenziswa yizinkinobho ezinzima.
Indawo yokurekhoda kancane ihlukanisa i-disk ezindaweni ezihlukene, lapho indawo ngayinye ihlukaniswa khona ibe yizigaba. Umphumela wukuthi ingxenye yangaphandle yediski izoba nemikhakha eminingi, futhi ngaleyo ndlela ingatholakala ngokushesha kunayo yonke indawo eseduze nendawo yediski.
Amathuluzi we-Defragmention, noma isofthiwe yokukhulula yamahhala , ingawasebenzisa ngokunenzuzo indawo yokurekhoda yendawo ngokuhambisa amafayela avame ukutholakala engxenyeni yangaphandle yediski yokufinyelela okusheshayo. Lokhu kushiya idatha oyisebenzisayo kaningi, njengamafayela amakhulu omlando noma amavidiyo, okumele agcinwe ezinkampanini eziseduze nendawo yedrayivu. Umqondo ukugcina idatha oyisebenzisayo okungenani njalo ezindaweni zokushayela ezithatha isikhathi eside ukuze ufinyelele.
Ulwazi oluthe xaxa mayelana nokurekhoda kwezakhiwo kanye nokwakhiwa kwemikhakha yediski yinkimbinkimbi kungatholakala ku-DEW Associates Corporation.
I-NTFS.com inomthombo omkhulu wokufunda okuthuthukile ezingxenyeni ezahlukene ze-hard drive, njengezingoma, imikhakha, namaqoqo.
