Ib tug hard disk drive (abbreviated li HDD) feem ntau hu ua lub hard drive yog lub ntsiab cia khoom ntawm lub computer. Nws khaws cov OS, software npe, thiab lwm yam ntaub ntawv tseem ceeb. Lub hard disk feem ntau yog cov khoom siv loj tshaj plaws. Nws yog ib qho khoom siv thib ob uas txhais tau tias cov ntaub ntawv tuaj yeem khaws cia mus tas li. Tsis tas li ntawd, nws tsis yog-volatile li cov ntaub ntawv nws muaj yog tsis erased thaum lub kaw lus kaw. Lub hard disk drive muaj cov hlau nplaum sib nqus uas tig ntawm kev kub ceev.

Hloov cov ntsiab lus
Txawm hais tias qhov no tsis yog lub ntsiab lus raug, tib neeg kuj hais tias C Drive hais txog lub hard disk. Hauv Windows, thawj qhov kev faib tawm ntawm lub hard drive yog los ntawm lub neej ntawd muab tsab ntawv C. Qee lub tshuab kuj muaj cov ntawv (C, D, E)… los sawv cev rau ntau qhov chaw ntawm lub hard disk. Lub hard disk drive kuj mus los ntawm ob peb lwm lub npe - HDD lub npe, hard disk, hard drive, taag disk, taag disk drive, taag tsav. Lub hauv paus nplaub tshev ntawm OS yog tuav los ntawm thawj lub hard drive.
Ib feem ntawm lub hard disk drive
Lub hard disk drive tig ntawm qhov nruab nrab ceev ntawm 15000 RPM (Revolutions Ib feeb) . Raws li nws tig ntawm kev kub ceev, nws yuav tsum tau tuav ruaj khov hauv qhov chaw kom tsis txhob muaj jarring. Braces thiab screws yog siv los khaws cov disk kom ruaj khov. Lub HDD muaj ib txheej ntawm cov voj voog uas hu ua platters. Lub platter muaj lub tsho sib nqus ntawm ob qho tib si - sab saum toj thiab hauv qab. Tshaj ntawm lub platter, ib sab caj npab nrog lub taub hau nyeem / sau. R / W lub taub hau nyeem cov ntaub ntawv los ntawm lub platter thiab sau cov ntaub ntawv tshiab rau hauv nws. Tus pas nrig uas txuas thiab tuav cov platters ua ke yog hu ua spindle. Ntawm lub platter, cov ntaub ntawv khaws cia magnetically kom cov ntaub ntawv tau txais kev cawmdim thaum lub kaw lus kaw.
Yuav ua li cas thiab thaum twg R / W lub taub hau yuav tsum txav yog tswj los ntawm ROM tswj pawg thawj coj. Cov R/W taub hau yog tuav nyob rau hauv qhov chaw los ntawm tus actuator caj npab. Txij li thaum ob sab ntawm lub platter yog coated magnetically, ob qhov chaw tuaj yeem siv los khaws cov ntaub ntawv. Txhua sab muab faib ua sectors. Txhua sector yog ntxiv muab faib ua lem. Cov lem los ntawm ntau lub platters tsim ib lub tog raj kheej. Kev sau cov ntaub ntawv pib los ntawm kev khiav tawm sab nraud thiab txav mus rau sab hauv thaum txhua lub tog raj kheej tau ntim. Lub hard drive muab faib ua ob peb partitions. Txhua qhov muab faib tau muab faib ua ntim. Cov Master Boot Record (MBR) thaum pib ntawm lub hard drive khaws tag nrho cov ntsiab lus hais txog kev muab faib.
Cov lus piav qhia lub cev ntawm lub hard drive
Qhov luaj li cas ntawm lub hard drive yog piv rau cov ntaub ntawv rov qab. Txawm li cas los xij, nws hnyav ntau dua. Hard drives tuaj nrog pre-drilled qhov ntawm ob sab uas pab nyob rau hauv mounting. Nws yog mounted rau lub computer rooj nyob rau hauv lub 3.5-nti tsav bay. Siv lub adapter, nws tseem tuaj yeem ua tiav hauv 5.25-nti tsav bay. Qhov kawg uas muaj tag nrho cov kev sib txuas yog muab tso rau sab hauv ntawm lub computer. Hauv qab kawg ntawm lub hard drive muaj cov chaw nres nkoj txuas mus rau lub motherboard, lub zog hluav taws xob. Jumper nqis ntawm lub hard drive yog rau kev teeb tsa li cas lub motherboard yuav paub txog lub hard drive yog tias muaj ntau lub drives.
Lub hard drive ua haujlwm li cas?
Lub hard drive tuaj yeem khaws cov ntaub ntawv mus tas li. Nws muaj lub cim xeeb tsis hloov pauv, yog li koj tuaj yeem nkag mus rau cov ntaub ntawv hauv HDD thaum koj hloov ntawm koj lub cev tom qab kaw nws.
Lub computer yuav tsum muaj OS ua haujlwm. HDD yog qhov nruab nrab qhov chaw ua haujlwm tuaj yeem nruab. Kev txhim kho cov kev pab cuam kuj yuav tsum muaj lub hard drive. Tag nrho cov ntaub ntawv uas koj download tau yog khaws cia mus tas li nyob rau hauv lub hard drive.
R / W lub taub hau saib xyuas cov ntaub ntawv uas yuav tsum tau nyeem los ntawm thiab sau rau hauv lub tsav. Nws extends tshaj lub platter uas yog muab faib ua lem thiab sectors. Txij li thaum lub platters tig nrog kev kub ceev, cov ntaub ntawv tuaj yeem nkag mus yuav luag tam sim. Lub taub hau R / W thiab lub platter yog sib cais los ntawm qhov sib txawv nyias.
Dab tsi yog hom hard drives?
Hard drives tuaj nyob rau hauv ntau qhov ntau thiab tsawg. Dab tsi yog hom hard drives muaj? Lawv sib txawv li cas?
Lub flash drive muaj lub hard drive. Txawm li cas los xij, nws lub hard drive yog qhov txawv ntawm cov tsoos ib txwm muaj. Qhov no tsis tig. Lub flash drive muaj ib tug built-in Solid-state drive (SSD) . Nws txuas nrog lub computer siv USB. Ib tug hybrid ntawm SSD thiab HDD hu ua SSHD kuj muaj.
Ib qho hard drive sab nraud yog ib txwm siv lub hard drive uas tau muab tso rau hauv rooj plaub kom nws tuaj yeem siv tau sab nraud ntawm lub computer. Hom hard drive no tuaj yeem txuas nrog lub computer lossis siv USB/eSATA/FireWire . Koj tuaj yeem ua rau koj lub hard drive sab nraud los ntawm kev tsim ib lub thawv rau hauv koj lub hard drive ib txwm muaj.
Lub peev xwm cia ntawm lub hard drive yog dab tsi?
Thaum nqis peev hauv PC / laptop, lub peev xwm ntawm lub hard drive yog qhov tseem ceeb los xav txog. Lub hard drive nrog lub peev xwm me me yuav tsis muaj peev xwm tuav tau ntau cov ntaub ntawv. Lub hom phiaj ntawm cov cuab yeej thiab hom cuab yeej tseem ceeb thiab. Yog tias feem ntau ntawm koj cov ntaub ntawv yog thaub qab hauv huab, lub hard drive nrog lub peev xwm me dua yuav txaus. Yog tias koj xaiv khaws cia feem ntau ntawm koj cov ntaub ntawv offline, koj yuav xav tau lub hard drive nrog lub peev xwm ntau dua (nyob ib puag ncig 1-4 TB). Piv txwv li, xav txog koj tab tom yuav ib ntsiav tshuaj. Yog tias koj yuav siv feem ntau los khaws cov yeeb yaj kiab ntau, mus rau ib qho nrog 54 GB hard drive yuav yog qhov kev xaiv batter dua li qhov hais, muaj peev xwm ntawm 8 GB.
Koj lub cev puas ua haujlwm yam tsis muaj lub hard drive?
Qhov no nyob ntawm tus BIOS kev teeb tsa. Cov cuab yeej kuaj xyuas seb puas muaj lwm yam khoom siv bootable hauv kev khau raj. Yog hais tias koj muaj ib tug bootable flash drive, nws yuav siv tau rau booting tsis muaj ib tug hard drive. Booting dhau lub network nrog ib puag ncig ua ntej-boot ua haujlwm tseem ua tau, txawm tias tsuas yog hauv qee lub khoos phis tawj xwb.
HDD Tasks
Dab tsi yog cov haujlwm uas koj tuaj yeem ua nrog koj lub hard disk drive?
ib. Hloov daim ntawv tsav tsheb - Raws li tau hais ua ntej, cov ntawv sau tau siv los sawv cev rau qhov sib txawv ntawm qhov tsav. C sawv cev rau lub hard drive tseem ceeb thiab nws tsis tuaj yeem hloov pauv. Txawm li cas los xij, cov ntawv uas sawv cev rau sab nraud tuaj yeem hloov pauv.
