Kokulula kuya kokulukhuni: idivayisi idrayivu kanzima

Omunye Izingxenye ezisemqoka iyiphi ikhompyutha iyona hard drive. Le divayisi eyaziwa ngaphansi amagama anzima "isikulufa", "umshanelo" zhestkach "," HDD "," kunzima ". Lesi sakamuva ukweleta kwaqala igama IsiZulu - Hard Drive Disc (HDD), ngesiRashiya colloquially saba "kanzima." Winchester uhlobo kolwazi isitoreji, idatha lapho, ngokungafani inkumbulo agcinwayo ngisho noma amandla ehluleka ngokuphelele. Ngokwezinga elithile, ungakwazi ukukhonza njengomdala analog elidala ividyo ne-odiyo amateyipu, lapho ifilimu kazibuthe yenza umsebenzi ofanayo njengoba disk e-hard drive.

Akungabazeki ukuthi abaningi abanikazi ikhompyutha ungathanda ukufunda kudivayisi idrayivu kanzima. Yini iphumele ngaphakathi uma zivulwa, kungani kukhona ngitshiyoza umsindo lapho wokufundwayo asebenzayo / bhala, nokunye. Futhi endabeni kukhona iwindi kwenjongo engaziwa. Kunemibuzo eminingi, kodwa hard disk kudivayisi futhi usalokhu uyimfihlakalo.

Kulesi sihloko sifuna ukuba asikhanyisele amaphoyinti aphezulu. Ngaphandle kwalokho, mhlawumbe, umsebenzisi ukwazi onquma eyakho ukulungisa drive wabo onzima ne kwazo kunjalo, cabanga izikhathi eziyishumi mayelana zibheke lokhu futhi uxhumane isikhungo service.

Amacala wonke hard drive ekhona zenziwa metal. On the underside we etholakalayo electronics ebhodini. Chip kungenziwa soldered kokubili ngaphandle (imodeli ubudala), futhi ngaphakathi. On ukusebenza asithinteki, ngaphandle ngephutha ubuhlungu ophumile chip nge ilungiselelo yangaphakathi engenakwenzeka.

kanzima kudivayisi disk kuhilela ukubeka phezu isilawuli ikhadi (MCU), inkumbulo sesikhashana chip (DDR ajwayelekile), module control lifundza (ukuqoshwa) amakhanda - VCM, inkumbulo ROM ukulawula firmware kanye diode zokuzivikela (TV). Ibhodi ehlangene izakhi yangaphakathi izindlu (containment) zethusi clamping oxhumana.

Yiqiniso, idivayisi idrayivu kanzima ayikwazi waqonda ngaphandle kokukhipha (zeqiniso noma ngokwengqondo) ikhava phezulu. Ngaphakathi kwi lokuphotha motor olulodwa (kusukela linemibhikisho 5.400 ukuba 15,000 ngomzuzu, kuye ngokuthi imodeli) ibekwe CD eziningana kusuka impahla non-conductive. On ezindaweni zawo camera ungqimba magnetizable: khumbula amakhasethi - ngesisekelo itheyiphu polymeric kwakukhona. idiski ngamunye ibekwe nge-engela elingama ekhethekile sokunciphisa umoya lapho zindiza obumba edingekayo komoya. Uhlaka, okuyinto ezibekwe enisemikhawulweni ikhanda, esimweni off iqinile ngendlela yokupaka endaweni ekhethekile ngaphandle kwamanzi disc nge isiqhebezo futhi (noma) kukazibuthe. Ngemva ukukhuthazwa lokuphotha kudala Ukuhamba VCM ikhadi ovula Uhlaka futhi ubonisa it in the isikhundla sabasebenzi. Shona ngesikhathi esifanayo ungathinti ubuso disc, futhi fly phezu kwabo phezu hovercraft. By endleleni, uma ukukhubaza amandla ukujikeleza kumanele amandla Generating zamanje eyanele ukuletha amakhanda endaweni yokupaka (eminyakeni engaba ngu-20-30 edlule, kwakudingekile ukuba uhlelo ephezulu ezingeni yokupaka).

Ngakho, akukho cleaner ngaphakathi hard drive, kanye "amawindi" e izindlu kudingeka nokulinganisa ingcindezi ngaphakathi nangaphandle. Yiqiniso, emoyeni ngaphakathi kuyinto kakhulu khulula ngothuli. Ngitshiyoza asebenzayo ukusetshenziswa idrayivu kanzima kwenzeka ngenxa njalo ukubeka amakhanda kungxenye wayefisa disk (ithrekhi). Nokho, ethambile uchofoze uma ilokhi kungadalwa ukususwa endaweni yokupaka noma imikhawulo self-test.

Phela, nguye wangaphandle hard disk kudivayisi nse. Ukwehluka: Imodeli kuthandwa ngesisekelo inkumbulo okuqinile-isimo bahlinza izimiso ehlukene ngokuphelele.
