Qes-qib hom tsis yog tus txheej txheem rau programmatically hloov cov ntaub ntawv kaw ntawm lub hard disk. Qhov no yog cov txheej txheem ntawm kev hloov lub cev ntawm cov platters uas yog nyob rau hauv cov ntaub ntawv nyuaj. Rau cov qauv niaj hnub (ATA) nyuaj tsav, xws li kev ua haujlwm tau ua ib zaug xwb, thaum lawv raug tso tawm los ntawm kev tsim cov nroj tsuag. Ntxiv mus, txhua tus neeg tsim khoom siv nws tus kheej kev teeb tsa thiab algorithms rau cov haujlwm no.

Txhawm rau nqa cov txheej txheem qib qis ntawm koj lub hard drive, koj yuav tsum tau yuav cov khoom tshwj xeeb - "Tus neeg saib xyuas". Lossis nrhiav chaw pabcuam lossis chav kuaj xyuas uas muaj kev cuam tshuam nrog cov ntaub ntawv rov qab thiab muaj cov khoom siv ntawd. Nov yog cov cuab yeej siv kim dua thiab tsis tshua muaj tshwm sim. Ntxiv nrog rau tus kws pabcuam, koj tseem yuav xav tau cov ntaub ntawv ntawm cov kev teeb tsa xav tau rau cov qauv qis ntawm kev siv lub zog ntawm koj lub chaw tsim khoom tshwj xeeb thiab qauv - lawv tau sau rau cov xov xwm tshwj xeeb uas siv los ntawm cov neeg pabcuam. Nws tsis zoo li tias cov ntaub ntawv no rau "txawv teb chaws" qauv yuav nyob ntawm qhov chaw pov tseg ntawm ib qho twg, txawm tias muaj kev pab cuam muaj npe loj heev. Tej zaum lawv tau sau rau hauv ib qho chaw hauv cov kev faib haujlwm hauv cheeb tsam hauv Ministry of Internal Affairs tshwj xeeb hauv cov teeb meem txhaum cai hauv koos pij tawj. Yuav ua li cas los sib tham txog kev teeb tsa qis ntawm koj lub hard drive nrog cov cai no nyob ntawm koj txoj kev sib raug zoo nrog lawv.

Lwm txoj hauv kev ua cov qauv qis ntawm kev siv lub zog yuav xav tau HDD tsim ua ntej txog xyoo 1998. Lub sijhawm ntawd, kev faib cov hard drive yog ua raws li cov ntsiab cai sib txawv thiab hom kev teeb tsa no tuaj yeem ua los ntawm kev siv lub zog nyuaj nws tus kheej. Cov. Ntxiv nrog rau qhov qub txaij qub qub, koj tseem xav tau cov software tsim nyog - lub BIOS ntawm tib lub xyoo ntawm kev tsim khoom nrog kev xaiv LLF-kev xaiv tus qauv. Muaj kev teeb tsa tag nrho cov no hauv koj lub khoos phis tawm, koj tuaj yeem siv BIOS tsis tshua muaj tshwm sim los ua qhov tsis tshua muaj hard drive nyob rau theem qis.

Rau cov hom phiaj tshaj tawm, qee cov tuam txhab software hu ua qib qis hom ntawv sau tag nrho cov ntim ntawm lub hard drive nrog zeros lossis cov cim random ("khib nyiab"). Qhov no hom ntawm cov ntawv cog lus hard disk feem ntau yog siv los cais qhov muaj peev xwm rov ua cov ntaub ntawv yav tas los khaws cia ntawm daim disk. Yog tias qhov kev hloov pauv rau cov kev ua tiav qib qis-tus qauv tau txaus rau koj lub hom phiaj, tom qab ntawd rub tawm thiab teeb tsa qhov kev pabcuam tsim nyog rau ntawm cov tshaj tawm. Piv txwv, HDD Hom Qib Qis uas tsis muaj dab tsi lossis MHDD qhov kev pab cuam los ntawm qhov chaw tsim khoom hauv tsev. Ob ntawm lawv yog pub dawb xwb, thiab cov txheej txheem nyob ntawm hom kev kawm twg koj xaiv.
