Txhais ntawm kev ruaj ntseg lwv thiab nws ua li cas Daim Ntawv Pov Thawj Zog
Kev Tso Cai Lwv Nkag yog lub npe uas tau muab rau cov lus txib ntawm lub firmware ntawm PATA thiab SATA raws li cov tsav nyuaj .
Kev ruaj ntseg yuam commands yog siv raws li cov ntaub ntawv kev kho mob kom tau tag nrho cov ntaub ntawv ntawm lub zog tsav.
Thaum ib tus tsav nyuaj tau muab tshem tawm nrog ib qho kev pab cuam uas siv cov Kev Ruaj Ntseg Ruaj Ntseg cov lus txib, tsis muaj ntaub ntawv xa rov qab , qhov muab faib ua haujlwm rov qab, los yog lwm cov ntaub ntawv rov qab yuav tau muab cov ntaub ntawv tawm los ntawm tus tsav.
Lus Cim: Kev Tso Cai Lwv Nkag, los yog cov ntaub ntawv muaj tiag tiag, tsis yog tib yam li xa cov ntaub ntawv mus rau hauv koj lub tshuab siv Recycle Bin lossis pov tseg. Tus qub yuav "mus tas li" rho tawm cov ntaub ntawv, whereas tom kawg tsuas tsiv cov ntaub ntawv rau ib qhov chaw uas yoojyim yoojyim tawm ntawm lub system. Koj tuaj yeem nyeem ntxiv txog cov ntaub ntawv so los ntawm qhov chaw txuas rau saum toj no.
Kev Tso Cai Lwv So Los Txhawm
Txoj Kev Siv Cov Ntaub Ntawv Nruab Nrab ruaj ntseg yog siv raws li hauv qab no:
- Kis 1: Sau ib binary los yog xoom
Yuav tsis muaj pov thawj ntawm qhov sau tshaj qhov sau tseg vim tias qhov sau ntawv tshwm sim los ntawm tus tsav tsheb , txhais tau hais tias tus tsav kev tshawb fawb sau ntawv tsis pub leej twg tsis tuaj.
Qhov no ua rau kev ruaj ntseg Erase heev ceev tshaj rau lwm cov ntaub ntawv kev kho mob cov ntaub ntawv thiab arguably zoo dua.
Muaj qee yam kev ruaj ntseg yuam kev muaj xws li POM ZOO LI CAS THIAB KEV HAIS HAIS TIAS LOS HAIS .
Ntxiv Txog Kev Ruaj Ntseg
Ob peb dawb zog tsav cov haujlwm ua haujlwm ntawm txoj kev hais kom ruaj ntseg. Saib cov npe ntawm Cov Ntawv Qhia Txog Kev Tsim Kev Puas Tsuaj Ntawv Dawb rau cov kev qhia ntxiv.
Txij li thaum Luag Txav Qis yog ib qho chaw khaws ntaub ntawv cia tag nrho , nws tsis muaj raws li cov ntaub ntawv los so thaum rhuav tshem cov neeg cov ntaub ntawv lossis cov cwj pwm, tej yam cuab yeej uas hu ua file shredders yuav ua tau. Pom Kuv Cov Ntaub Ntawv Dawb Shredder Software Cov Kev Pab rau ib daim ntawv teev cov kev pab cuam zoo li ntawd.
Siv Cov Kev Siv Luag Lwv los tshem tawm cov ntaub ntawv los ntawm ib qho kev tsav nyuaj yog feem ntau xav tau qhov zoo tshaj plaws los ua li ntawd vim qhov kev ua tiav yog ua tiav los ntawm tus tsav nws tus kheej, tib lub xov tooj cua uas sau cov ntaub ntawv hauv thawj qhov chaw.
Lwm cov kev tshem tawm cov ntaub ntawv los ntawm ib tus tsav nyuaj tej zaum yuav tsis tshua zoo vim lawv vam khom txheej txheem ntau tshaj li cov kev sau overwriting.
Raws li Lub Koom Haum Lub Ntiaj Teb Cov Qauv thiab Tshuab (NIST) Ntawv Tshwj Xeeb 800-88 [Cov ntaub ntawv PDF ], tsuas yog cov qauv ntawm cov ntaub ntawv software raws kev tu tsiaj txhawm rau yuav tsum yog ib qho uas siv lub zog tsav lub Secure Erase commands.
Nws tseem ceeb heev kom nco ntsoov tias National Security Administration tau ua haujlwm nrog Lub Chaw Rau Cov Kev Sib Txawv Rau Kev Sib Xws (CMMR) hauv University of California, San Diego, los tshawb nrhiav cov ntaub ntawv tsav tsheb. Ib qhov txiaj ntsig ntawm qhov kev tshawb fawb no yog HDDErase , ib qho xov xwm muaj kev puas ntsoog software uas ua hauj lwm uas ua tiav los ntawm executing Secure Erase commands.
Kev ruaj ntseg lwv tsis muaj nyob ntawm SCSI nyuaj drives.
Kev Ruaj Ntseg Lwv lwm txoj kev uas koj yuav pom tau hais meej txog kev ruaj ntseg, tab sis tsis yog feem ntau.
Ceebtoom: Koj tsis tuaj yeem khiav haujlwm ruaj khov rau hauv ib qho kev tsav tsheb xws li koj tuaj yeem khiav cov lus txib ntawm qhov rais los ntawm qhov Kev Hais Kom Thoob Ntiaj Teb . Ua kom muaj kev ruaj ntseg yuam commands, koj yuav tsum tau siv qee qhov kev pab cuam uas txuas nrog lub zog tsav thiab txawm tias tom qab ntawd, tej zaum koj yuav tsis tau khiav qhov kev hais ua haujlwm manually.
Ruaj Ntseg Ruaj Ntseg vs Securely Erasing Hard Drive
Qee cov kev pabcuam muaj nyob rau hauv cov npe uas muaj kev ruaj ntseg nyob rau hauv lawv lub npe lossis tshaj tawm tias lawv tau muab cov ntaub ntawv tawm los ntawm cov tsav nyuaj.
Txawm li cas los xij, tshwj tsis yog lawv tshwj xeeb pom tias lawv siv lub zog tsav ruaj ntseg yuam kev, lawv yuav tsis ua.
