Sezvandinozvinzwisisa, chirongwa cheDood 5220.22-M hachibvumirwi (kana chero chero shanduro yakagadzirwa nedzidziso yekuchenesa sanamato) iyo inoshandiswa nevarume vakasiyana-siyana veCSA kusanganisira Dhipatimendi Rekuchengetedza, Dhipatimendi reMagetsi, Nuclear Regulatory Commission, uye Central Intelligence Agency.
Is DoD 5220.22-M Inofananidzwa Kupfuura Dzimwe Nzira Here?
Zvichida hazvibatsiri zvose zvakanyanya izvo deta rinopisa nzira yaunoshandisa. Sezvo vakawanda vedu vari kupukuta mitsipa yedu yakaoma vari kungoita kudaro tisati tatengesa dhiyo kana kuisa imwe OS , haifaniri kunge yakanyanya kufunganya pamusoro pokuti ingani mavara akasiyana-siyana ari kunyorwa kumotokari kune imwe kana zeros .
Kunyanya, vanhu vazhinji vanoedza kuwana dheta kubva kunotengwa zvakaoma motokari vangave vachishandisa zvishandiso zvezuva nezuva seRecuva , uye pavanenge vachishanda kuti vatsvake deta yakabviswa, havaiti zvakanaka kana deta ichidzima nzira yaitwa.
Zvisinei, paunosarudza nzira yekuchenesa sanitization, unogona kufunga kuti zvichazotora nguva yakareba sei kudzima motokari. Kana uine dambudziko guru chaizvo, Nyora Zero inotora nguva shoma yekupedzisa kudarika DoD 5220.22-M, iyo ichakurumidza kukunda imwe yakadai seGitmann iyo inogona kutamba kupfuura kupfuura kupfuura makumi matatu.
Uyewo funga kana zvinyorwa zvakaitwa mushure mekufamba. Sezvo dzimwe shanduro dzingashandisa nzira yaDoD 5220.22-M nenzira inoita kuti mumwe nomumwe anyore pamagumo echipfufuro chega, iyo yose inotora nguva yakareba kupfuura kushandisa imwe nzira yekupukuta iyo isingatenderi zvachose (se Secure Erase) kana kuti kumirira kusvika pakuguma kwekupedzisira kupfuura kuti ave nechokwadi chokuti data yakanyorwa.
Chimwe chinhu chinogona kusarudza nzira yaunoshandisa nayo iyo chaiyo data inoshandiswa kudhinda dhirairi rakaoma. Vamwe vanopukuta nzira, sezvinyora Zero, shandisa zero pane nzvimbo dzisingatauriki. Zvingaita kuti kushandiswa kwemavara akasiyana-siyana kunoita kuti zvive nyore kuti data inogona kuwanikwa zvakare.
