Kokulula ukuya koko kuntsonkothileyo; isixhobo hard diski

Enye yeendima eziphambili yayo nayiphi na ikhompyutha i hard drive. Esi sixhobo eyaziwa phantsi amagama anzima "iqhosha lemenyu", "umtshayelo" zhestkach "," HDD "," kunzima ". Le yokugqibela unetyala imvelaphi yayo igama IsiNgesi - Hard Drive Disc (HDD), in Russian asisifutshane ekudla ukuba 'nzima. " Winchester luhlobo yokugcina ulwazi, i-data apho, ngokungafaniyo memory iyagcinwa nokuba igunya akaphumeleli ngokupheleleyo. Ukusa kumlinganiselo othile, unako ukukhonza nje analog ividiyo audio tapes ubudala, apho magnetic umboniso owenza umsebenzi ofanayo njengoko lwe- nzima drives.

Akuthandabuzeki ukuba abanini ikhompyutha angathanda ukufunda isixhobo hard diski Kukho. Yintoni ivele ngaphakathi xa ivuliwe, kutheni kukho ntsholo imnandi isandi xa efundiweyo esebenzayo / bhala ulwazi, njalo njalo. Kwaye kwimeko kukho window injongo ezingaziwayo. Kukho imibuzo emininzi, kodwa isixhobo hard diski kwaye igcina ingaziwa.

Kweli nqaku esifuna ukuba asikhanyisele amanqaku athile aphambili. Ngapha koko, mhlawumbi, umsebenzisi ukwazi egqiba ukuqalisa ukulungisa zabo hard drive ne disassembling kunjalo, cinga izihlandlo ezilishumi malunga nokwenzeka oku qhagamshelana neziko inkonzo.

Amatyala zonke drives ezikhoyo nzima ezenziwe ngentsimbi. Kwicala elingaphantsi kwe bombane ezikhoyo ibhodi. Chip kungenziwa soldered zozibini ngaphandle (imodeli endala), yaye ngaphakathi. Kwi komsebenzi alichatshazelwa, ngaphandle kokuba ingozi buhlungu elibukhali chip ne ilungiselelo yangaphakathi engenakwenzeka.

isixhobo hard disk kubandakanya nokubambisa eli khadi (MCU), memory uxhaso chip (DDR eziqhelekileyo), lomnqongo wolawulo ufunda (recording) iintloko - VCM, ROM memory ulawulo firmware kunye diode zokhuseleko (TVS). Ibhodi edibene iziqalelo angaphakathi lwezindlu (ukuqulatha) ubhedu nokubotshwa abafowunelwa.

Kakade ke, isixhobo hard disk lungenakuqondeka ngaphandle kokususa isiciko (wokwenene okanye ngokwasengqondweni) ngaphezulu. Ngaphakathi kwi yinjini edibanise elinye (ukusuka revolutions 5.400 ukuya 15,000 ngomzuzu, kuxhomekeke model) wabeka neeCD ezininzi ukusuka material non-conductive. Kumphezulu wazo camera maleko magnetizable: ukukhumbula iikhasethi - isiseko tape polymeric apho. disc nganye obekwe kwi arc ekhethekileyo ashukimisayo uyila efunekayo air kwemali. Isakhelo, ezo ibekwe kwi eziphelweni intloko, xa urhulumente off busisigxina kwindawo yokupaka ezizodwa ngaphandle umphezulu disc nge kwikroba kunye (okanye) of the umazibuthe. Emva kokuba promotion yokuluka idala komoya ikhadi VCM ovula isakhelo kwaye uyixhome kwindawo esebenzayo. Head ngexesha elifanayo ningayichukumisi umphezulu disc, zidlule phezu hovercraft. Ngendlela, ukuba khubaza amandla ojikelezayo ukwanele esivelisa yangoku elaneleyo ukuzisa iintloko kwindawo yokupaka (malunga 20-30 kwiminyaka eyadlulayo, ukuba kuyimfuneko ukuba kumisela inkqubo yokupaka-kwinqanaba eliphezulu).

Ngoko ke, akukho emoyeni ngaphakathi kwi hard drive, yaye "iifestile" kwi lwezindlu ziyafuneka alinganayo uxinzelelo ngaphakathi nangaphandle. Kakade ke, umoya ngaphakathi kakhulu engenathuli. Ntsholo imnandi esebenzayo ukusetyenziswa hard disk kwenzeka ngenxa iintloko Positioning rhoqo isahlulo wacela disk (track). Kaloku, soft nqakraza xa lock ezinokubangelwa kususwa kwindawo yokupaka okanye imida self-test.

Ke kaloku, yangaphandle isixhobo hard disk ifana nqwa nale. Imeko engalawulwa ngulo mthetho: Le modeli ngokuya ithandwa ngokusekelwe memory esiqinileyo-karhulumente asebenza kwi siseko ezahlukeneyo ngokupheleleyo.
