Iinkcukacha kwiNkqubo yoLwazi lokuSula idatha
Uninzi lweefayile zenkqantosi kunye neenkqubo zokubhubhisa idatha zixhasa i-software ye-Zero ye- Writ based based data method to overwrite data ekhoyo ekhompyutheni yokugcina njenge- hard drive .
Indlela yokucwangcisa i-Zero yedatha ayinakuyeka iindlela zokubuyisela ezisekelwe kwi- hardware eziphambili ukusuka ekukhankeni ubuncinane idatha ethile esusiweyo, kodwa inokuthintela zonke iindlela zokubuyisela iifayile ezisekelwe kwi-software ukusuka ekuphakameni ulwazi kwi-drive.
Qaphela: Ngamanye amaxesha indlela yokubhala iZero, kwaye ngokuchanekileyo, ekubhekiselwe kuyo njengendlela engabonakaliyo Yodwa . Ikwabizwa kwakhona ngokuba yi- zero fill fill or fill-fill .
Yintoni ebhaliweyo?
Ezinye iinkqubo zokuhlanjululwa kwedata, ezifana neG Gutmann kunye ne- DoD 5220.22-M , ziya kubhala iinhlamvu ezingenangqangi malunga nolwazi olukhoyo kwi-drive. Nangona kunjalo, indlela yokuhlanjululwa kwedatha ye-Zero, ayikho into emangalisayo, iqhutyelwa ukuphunyezwa ngendlela elandelayo:
- Ukupasa 1: Ubhala iZero
Ezinye iinkqubo zendlela yokubhala i-Zero zingabandakanya ukuqinisekiswa emva kokupasa kokuqala, kunokubhala umgca ngaphandle kwe-zero, okanye ubhale i-zeros kwiidlula eziliqela, kodwa ezo azizona iindlela eziqhelekileyo zokwenza.
Iphulo: Uninzi lweeprogram zesoftware ezixhasa ukubhala iZero zibonelela indlela yokwenza udidi lomntu kunye nenani lamaxesha okuqinisekisa. Oku kuthethi, tshintsha ezo zanele kwaye awuyikusebenzisa kwakhona iZere Bhala kwakhona.
Ngaba Ubhala Ukhuseleko Olunokwenzela Ukuchithwa kwedata?
Kunokwenzeka ukuba, ewe. Nangona kunjalo ...
Ezinye iinkqubo zokuhlanjululwa kweedatha ziyifake idatha yakho eqhelekileyo, efundekayo kunye nabalinganiswa bengahleli. Njengoko kuthethwe ngentla, Bhala iZero into efanayo kodwa usebenzisa, kakuhle ... zeros. Ngokwenene, xa usula i-hard drive kunye ne-zeros uze uyiphonye, i-diversified dumpster diver yakho eyayibambayo ayiyi kukwazi ukufumana nayiphi na idatha echitshiweyo.
Ukuba kunjalo, unokuzibuza ke ngoko, kutheni ezinye iintlobo zedatha zisula iindlela nokuba zikhona. Ngayo yonke idatha isula iindlela ezikhoyo, yintoni injongo yenkonzo yokuzalisa i-zero? Inkqubo yeRandom Data , umzekelo, ubhala abalinganiswa bemizila kwi-drive esikhundleni se-zeros, ngoko ke njani okuhlukileyo kunokubhala iZero okanye nawuphi na omnye?
Enye into ayikho nje into ebhalwe ngayo umlingiswa kodwa indlela efanelekileyo ngayo yokwenza i-data ibhalwe ngaphezulu. Ukuba kuphela enye yokubhala ibhalwa, kunye nesofthiwe ayiqinisekisi ukuba zonke iinkcukacha zedatshulwa, ngoko indlela ayiyi kusebenza ngendlela efanelekileyo .
Ngamanye amagama, ukuba usebenzisa i-Zero yokubhala kwi-drive enye kwaye uqinisekisa ukuba yonke idatha ibhalwe ngaphezulu, ngoko unokuqiniseka ukuba ulwazi alufumaneki ukuba luphinde lufumaneke ngaphandle kokuba ukuba idatha efanayo ifakwe kwiNkqubo yeDatha yeRayibhile kodwa akaqinisekanga ukuba ngalinye icandelo litshintshiwe ngeelwimi ezingenanto.
Nangona kunjalo, abalinganiswa abathile banokubonelela ngolondolozo olungcono kunabanye. Ukuba inkqubo yokubuyiswa kwefayile iyazi ukuba idatha yenziwe nge-zeros kuphela, yenza kube lula kakhulu ukucoca ukuba yeyiphi idatha ekhona ngaphandle kokuba inkqubo ayikwazi ukuba imifanekiso esetyenziswayo, njengaleyo kwindlela ye- Schneier .
Esinye isizathu sokuba yonke enye idatha isula iindlela kukuba ezinye iinkampani zifuna ukubonisa ukuba ulwazi lwabo luyasuswa ngendlela ethile ekhuselekileyo yokuthintela ukubuyiswa, ngoko zisebenzisa indlela ethile yokuhlanjululwa kwedatha kunye neeparitha ezithile zazo zonke iifayile zabo zokusula iimfuno .
IiNkqubo eziNika iNkxaso
Kwi- Windows 10 , i- Windows 8 , i- Windows 7 kunye ne- Windows Vista , umyalelo wefomathi othembekileyo, ngokuzenzekelayo, usebenzisa indlela yokuhlanjululwa kwe-Zero kwindlela yokwenza ifomathi . Ungayisebenzisa loo myalelo kwi- prompt prompt yokubhala i-zeros kwi-hard drive ngaphandle kokukhuphela nayiphi na isofthiwe esongeziweyo okanye isicaciso esithile.
Jonga indlela yokusebenzisa i-Format Command yokubhala iZeros kwiDrive Drive malunga neenkcukacha. Akunjalo nje kulula njengoko kuvela xa uzama ukwenza oku kwi-drive yakho yokuqhuba.
Kukho iinkqubo zenkxaso yesithathu ezixhasa ukusebenzisa indlela yokubhala yeZero yokususa idatha, njengeDBAN , i- HDShredder , i- KillDisk , kunye ne- Macrorit Disk Partition Wiper . Eminye yale nkqubo ingasetyenziswa ukucima i-hard drive oyisebenzisayo (njengeC drive) ngokusebenza kwi-disc okanye i- flash drive , kunye nabanye baleka ngaphakathi kwinkqubo yokusebenza ukucima ezinye iitshini, njengezinto ezikhutshwayo.
Ezinye izixhobo zisebenzisa indlela yokubhala iZero yokususa iifayile ezithile kunokuba yonke into efana neenkqubo ezilapha ngentla. Imizekelo embalwa yezixhobo ezinje ziquka i- WipeFile ne- BitKiller .
Uninzi lweenkqubo zokubhubhisa idatha luxhasa iindlela ezininzi zokuncedisa ukuhlengahlengiswa kweefayile ngaphezu kokubhala iZero, ngoko unako ukukhetha indlela eyahlukileyo, ukuba unomdla, emva kokuba uvule inkqubo.
