Ngokuqinisekileyo ngaphezulu kwesihlandlo esinye kwenzeke kuwe ukuba ngempazamo ucime idatha ethile, okanye ucinga ukuba akusafuneki kwaye kuyacaca ukuba kamva kufuneka uphinde ufumane olo lwazi kwaye ngenxa yenkqubo ethile okanye ikhowudi onokuyifumana; Kodwa uza kuthini xa ufuna ukucima idatha? Njengokuba kukho izixhobo zokubuyisela kwimeko yesiqhelo sinokufumana izixhobo zokutshabalalisa, ezinje nge Ukukrazula
Esi sixhobo singena ngaphakathi kwephakheji engundoqo efakwe ngaphambili ngaphakathi kulo naluphi na ulwabiwo lweLinux, le phakheji engundoqo ibandakanya uthotho lwezixhobo ezisisiseko zomgca wokuyalela, phakathi kwazo ukukrazula, ayisiyonto ingaphezulu kwesincedisi esime ngaphandle ngokulula kakhulu ukuba sisebenzise kwaye ngaphezulu kwako konke okusebenzayo ukutshabalalisa yonke into esiyifunayo (okanye into esingasayifuniyo) njengoko igama layo lisitsho.
Ukusebenza Ukukrazula Kukuba ibhala ngaphezulu ifayile okanye idatha esiyibonisa amatyeli aliqela (25 ngokungagqibekanga) oku kwenziwa kusetyenziswa izikimu ezininzi zokubhaliweyo, ukuguqula yonke into equlathe ifayile yoqobo, ibe ngomnye umxholo owahluke ngokupheleleyo ngolwazi olungenantsingiselo.
Kubasebenzisi abangaqhelekanga, banokuphonononga yonke into esi sixhobo esivumela ukuba sijonge kuyo umntu shred.
Emva koku masiye kwicandelo elisebenzayo; Masiqale ngomzekelo wokusetyenziswa kwayo, kuqala ukubona ukuba yeyiphi malunga nokuthatha idiski enzima okanye isahlulelo esithile: ukuba besinaso isahlulelo esilawulwa ngokobukhulu, sisebenzisa lo myalelo lsblk Sifumana ngokukhawuleza isahlulelo esisifunayo, Ngomyalelo unyuka ziya kudityaniswa kwaye emva koko kunye ukukrazula Siza kukunika uphononongo ngexesha elifanelekileyo:
Shred -vzn 0 / dev / sda1
Ngomgca odlulileyo siza kususa yonke idatha ekwahlulelo "sda1" kunye nezinye iiparameter ezinje nge "v" esibonisa inkqubela phambili yokusebenza, "z" ezisinceda ukuba sigubungele intshabalalo ngokubhala ngaphezulu ngoziro Ekupheleni kwaye "n" ilandelwe lilungu, okuthetha ukuba inkqubo iyakwenziwa kube kanye ngaphandle kokuziphinda; Okukhona inkqubo iphindaphindwa, kokukhona kucinywa ngokufanelekileyo, kokukhona kufuneka kuthathelwe ingqalelo xa usebenzisa i-Shred kukuba oku yinkqubo ecothayo, ngakumbi ukuba siza kuyisebenzisa kwiidiski ezinobungakanani obukhulu; Lo mzekelo ubonakalisa kubo unokucetyiswa ukuba usetyenziswe ngumsebenzisi ongeyongcali okanye umsebenzisi oqhelekileyo.
Ukuba siza kuyicima ifayile kunokuba lula kwaye ngokukhawuleza okukhulu:
shred -u / umendo / ifayile
Ukhetho "u" unoxanduva lokususa idatha. Nangona kunjalo, ukuba sidibana nefayile enkulu kakhulu, sinokusebenzisa ngokuchanekileyo inyathelo elinye, sidibanisa nje ukucima ipharamitha kwaye siyixelele ukuba iphinde le nkqubo kathathu:
shred -ubzn 2 / indlela / ifayile
Inxalenye apho kufuneka silumke khona silusebenzisa phi ulusu, kuba isenokungasebenzi kakuhle kuqwalaselo oluthile lokugcina okanye ngazo zonke iinkqubo zefayile.
Kulungile, ekuphela kwento engandifanelanga kukuba ndicinga ukuba kwii-hard drive zangoku ezibhalwe ngokulula akunakwenzeka ukubuyisa nayiphi na idatha, akuyomfuneko ukuyenza amaxesha angama-25. Mhlawumbi yenzelwe ukuba isetyenziselwe naluphi na uhlobo lwesixhobo, andazi ukuba iteyiphu iyafuneka ukuba ibhalwe ngaphezulu amatyeli amaninzi ukukhusela ukubuyela kwimeko yesiqhelo.
Ndiyazibuza ukuba ingaba le datha ibhalwe ngaphezulu iyimfuneko nakwi-SSD hard drive
Ii-SSD zizinto ezahlukileyo ngenxa yenkqubo yazo yokubhala, ehlala ithintela ukubhala ngaphezulu kwendawo enye. Ndiye ndakhangela ndaza ndachaza into apha apha:

Bavakalisa ukuba isoftware ethile evela kumenzi ngamnye isetyenzisiwe, bakwaphawula kuMagqabantshintshi oMbiyo osasazo lwe-linux kwiphepha labo abathi basebenzisa isoftware yasimahla enjenge-gparted, njl.
En la búsqueda veo un artículo anterior de Desdelinux: https://blog.desdelinux.net/como-limpiar-tus-discos-y-borrar-archivos-en-forma-segura/ apho yayisele ichaziwe ukuba yayingeyiyo i-100% esebenzayo kwi-SSD. Amagqabantshintshi avela ku "desikoder" anika indawo elungileyo yokutshintsha: intloko -c $ (wc -c FILE) / dev / urandom> FILE
Isifundo sijongeka njengokubi ngokususa i-SSD: cseweb.ucsd.edu/~m3wei/assets/pdf/FMS-2010-Secure-Erase.pdf
Ke ukuba ngenye imini ulahla i-SSD eyayinolwazi olubalulekileyo kuyo, qiniseka ukuyilungisa kwaye uyiqhube.
Inkcazo yendlela yokufaka iidiski ze-SSD kwiLinux inomdla, kodwa ngakumbi ngengqondo yokuphepha ukwahlulwa kunokuba ucime umxholo: http://www.atareao.es/ubuntu/linux-y-discos-duros-ssd/
Ke okwangoku andizukukwazi ukucima into kwi-SSD.

En la búsqueda veo un artículo anterior de Desdelinux: blog.desdelinux.net/como-limpiar-tus-discos-y-borrar-archivos-en-forma-segura/ donde ya se comentaba que no era 100% efectivo en un SSD. Un comentario de «desikoder» da un buen sustituto de shred: head -c $(wc -c ARCHIVO) /dev/urandom > ARCHIVO

Ingandinceda kodwa ndizicima njani iifayile kwidiski ye-GNU ???
