Informatec Digital » Izinsiza » Indlela yokususa amafayela ngokuphephile ukuze angaphinde atholakale

Abasebenzisi abaningi bacabanga ukuthi, lapho bekhipha i-Recycle Bin, Amafayela abo anyamalale unomphelaAkukho okungaba kude neqiniso: ezimweni eziningi, leyo datha isekhona kudiski futhi ingakwazi thola kabusha ngamathuluzi okutakula mahhalaUma uzothengisa i-PC yakho, uvuselele i-hard drive, noma ufuna nje ukulahla amadokhumenti abucayi, uzofuna ukufunda ukuthi unga... susa amafayela ngokuphephile nangokungenakulungiseka.

Emigqeni elandelayo uzothola umhlahlandlela ophelele kakhulu, osekelwe emithonjeni ehlukahlukene ekhethekile, echaza Zonke izindlela zokususa amafayela unomphelaKusukela kuzinsiza ezifana ne-Eraser noma i-SDelete, ngokusebenzisa imiyalo ye-Windows, izixazululo zezinkampani zangaphandle, i-HDD kanye ne-SSD erasure, kuya kuzinketho zokubhubhisa okungokoqobo okukhulu. Uzobona futhi kwenzekani ngempela uma "ususa" ifayelaYiziphi izingozi zokuphepha ezihilelekile ekungakwenzi kahle, nokuthi ungayikhetha kanjani indlela efanele esimweni ngasinye.

Kwenzekani ngempela uma ususa ifayela ku-Windows noma ku-macOS?

Uma ucindezela u-Delete kudokhumenti ku-Windows, uhlelo luzoqala Ayisuli idatha kudiski ngokushesha.Lokho ekwenzayo ukuyihambisa ku-Recycle Bin, lapho ihlala khona uze uyithulule, noma ukuyibuyisela endaweni yayo yokuqala.

Ngisho nangemva kokukhipha i-Recycle Bin, okuqukethwe kwefayela kuhlala endaweni efanayo ebonakalayo kudiski: Isikhala simakwe nje njengesitholakalayo ukuze sisetshenziswe kabushaUhlelo lususa ireferensi kuthebula lamafayela, kodwa ama-bits ahlala lapho kuze kube yilapho enye idatha iwabhala ngaphezulu. Uma nje lokho kubhala ngaphezulu kungenzeki, uhlelo lokutakula lungenza Ukwakha kabusha ulwazi kulula kakhulu..

Ku-macOS, inqubo iyafana: uma uthumela ifayela kudoti bese "ulisusa", Okuqukethwe akuhlanzwa ngokusheshaFuthi, isikhala siyakhululwa ezingeni elinengqondo, kodwa okuqukethwe okungokoqobo kungahlala isikhathi eside.

Leli qiniso lisho ukuthi noma yimiphi imishini oyinikeza ukufinyelela, ukuyithengisa, noma ukuyiphinda uyisebenzise, Kungase kube namadokhumenti ayimfihloIzithombe, ama-payslip, imibiko yezokwelapha, ama-imeyili athunyelwe, amaphasiwedi e-Wi-Fi, imininingwane yasebhange… Uma umuntu wesithathu esebenzisa amathuluzi afana ne-Recuva, i-PhotoRec, noma ezinye izinhlelo zokutakula, kunethuba elikhulu lokuthi… thola lolo lwazi.

Umehluko phakathi kwe-HDD ne-SSD lapho kususwa idatha

Ukuze ukhethe indlela efanele yokususa idatha evikelekile, kubalulekile ukuqonda ukuthi izinhlobo ezahlukene zama-drive zigcina kanjani idatha nokuthi kanjani Ukugwema amaphutha lapho ufaka i-SSDKu-hard drive ye-mechanical (HDD), idatha igcinwa ku- amabhlogo ahambisanayo kumapuleti kazibutheUma ifayela lisuswa, uhlelo luphawula lawo mabhulokhi njengamahhala, kodwa insimu yamagnetic emele ama-bits ihlala kuze kube yilapho omunye umbhalo uyishintsha.

Ku-solid-state drive (SSD), indlela ihlukile. Esikhundleni sama-magnetic platets, kusetshenziswa ama-flash memory chips, kanti isilawuli sangaphakathi senza imisebenzi edingekayo. ukuguguleka kokulinganaSabalalisa ukubhala kuyo yonke idrayivu ukuze wandise isikhathi sayo sokuphila. Lokhu kusho ukuthi ukuzama "ukubhala ngaphezulu umkhakha ofanayo izikhathi eziyi-10" akuqinisekisi, empeleni, ukuthi ubhala ngaphezulu ama-chip afanayo lapho ifayela lokuqala lalikhona khona.

Ngaphezu kwalokho, ama-SSD asebenza ngamabhulokhi asulwa ndawonye futhi asebenzisa imiyalo efana nalokhu I-TRIMUma uhlelo lokusebenza lumaka ifayela njengelisusiwe, lungathumela i-SSD umyalo wokuthi lawo mabhulokhi anengqondo awasenawo idatha evumelekile, ukuze, ezinqubweni ezilandelayo zokuhlanza kwangaphakathi, asuswe. sula lolo lwazi ngokomzimba.

Ngakho-ke, izindlela zakudala zokubhala ngaphezulu eziningi ezenzelwe ama-HDD (njengesikimu esidumile se-35-pass Gutmann) Azihlali zisebenza noma zidingeka kuma-SSDKula madrayivu, kuyalulekwa ukusebenzisa izinketho ezifana "nokususa okuphephile" komkhiqizi, izinsiza ezikhethekile ezihambisana ne-TRIM, noma okungcono nakakhulu, ukubethela kwediski ephelele + ukubhujiswa kokhiye.

Kungani ukususa amafayela ngendlela engaphephile kuyingozi yangempela

Ukusula nje i-Recycle Bin, ukususa amafayela ku-Explorer, noma ukwenza ifomethi esheshayo kusho ukuthi idatha eningi isatholakalaNoma ubani onokufinyelela ngokomzimba kukhompyutha, idrayivu ye-USB, kanye nesikhathi esithile angazama ukubuyisa ulwazi esebenzisa amathuluzi amahhala.

Lokhu akugcini nje ngokuthinta amafayela owakhumbula ukuwasusa. Izinhlelo ezifana ne-Windows ziyaqoqana okukhulu amafayela esikhashana kumafolda afana IsikhathiAma-cache, ama-backup amadokhumenti azenzakalelayo, noma izinguqulo zangaphambilini zikuvumela ukuthi, isibonelo, ubuyisele ifayela le-Word noma le-Excel elivaliwe ngokungalindelekile. Konke lokhu kungaqukatha idatha ebucayi kakhulu ukuthi awazi ukuthi zikhona.

Ezindaweni zezinkampani noma zemfundo, izinto ziba nzima nakakhulu: imibhalo yocwaningo, izizindalwazi ezinolwazi lomuntu siqu, imibiko yangaphakathi… Uma lawa madiski esetshenziswa kabusha, ethengiswa kabusha, noma elahlwa ngaphandle kwe- ukususwa okuphephile nokubhalwe phansiLokhu kuvula ithuba lokuvuza kwedatha kanye nokwephulwa kwezokuphepha okunzima ukuzithethelela.

Ngisho nasekhaya, izithombe zomuntu siqu, ama-ID scan, ama-payslip, noma amarekhodi ezempilo kungaba yinto engavamile. uswidi wokwebiwa kobunikazi noma ukukhwabanisa uma bewela ezandleni ezingafanele. Yingakho, uma idivayisi izoshintsha ubunikazi noma ishiya ukulawula kwakho, kungcono ukuphatha ukubhujiswa kwedatha njengokungathi ingxenye ebalulekile yokuphephahhayi njengemininingwane emincane.

Susa amafayela athile ngokuphephile nge-Eraser

Enye yezinhlelo zakudala ze-Windows Isisuliithuluzi lamahhala elivumela bhubhisa amafayela, amafolda kanye nesikhala samahhala ngokubhala ngaphezulu imikhakha lapho idatha ibikhona khona izikhathi eziningi. Umgomo wabo ukwenza ulwazi lungatholakali, ngisho nokusebenzisa isofthiwe ye-forensic ethuthukisiwe.

Ngemva kokufaka i-Eraser ku-Windows (isibonelo, inguqulo 6.2.0.2996 noma ngaphezulu), awudingi ukuvula i-interface yayo njalo uma ufuna ukuyisebenzisa. Uhlelo luhlangana ne-File Explorer kanye ne-Desktop, ukuze ukwazi qala ukususa okuphephile kusuka kumenyu yokuqukethweChofoza ngakwesokudla kufayela noma kufolda, khetha inketho ethi "Isula", bese ukhetha ethi "Susa".

Uhlelo luzokucela isiqinisekiso, lukukhumbuze ukuthi ukususwa kuzoba unomphelaUma sesamukela, i-Eraser izofaka umsebenzi kulayini wayo wemisebenzi bese iqala ukubhala ngaphezulu indawo yediski ehambisanayo. Indlela ezenzakalelayo ngokuvamile iyisikimu UGutmann ushaye amaphasi angu-35, kuphelele kakhulu, yize kuhamba kancane ngamafayela amakhulu.

Uma uvula isikhombimsebenzisi se-Eraser, ungenza ukusetshenziswa okuthuthukile kakhulu: dala imisebenzi ehleliwe, khetha ama-algorithms ahlukene (isibonelo, izindlela zokudlula okukodwa ngedatha engahleliwe noma amazinga afana ne-British HMG IS5), sula ibhodlela lokusebenzisa kabusha kanye nesikhala esingasetshenziswanganoma ulungise imvamisa ukuze ukuhlanza kusebenze ngokuzenzakalelayo.

Kuma-hard drive omshini, ama-pass ambalwa anedatha engahleliwe anele ngokwanele vimbela ukubuyiselwa kwamafayela ngendlela engokoqoboIzindlela zokudlula ezingu-35 zigcinelwe izimo noma izimo ezidinga kakhulu lapho kuphathwa khona ulwazi olubucayi kakhulu, kucatshangwa ukuthi inqubo izothatha isikhathi eside kakhulu.

Izindlela eziyisithupha zokususa amafayela ku-Windows (kusukela kokulula kuya kokuthuthukile kakhulu)

I-Windows inikeza izindlela eziningana zokususa amafayela, kodwa ezinye kuphela ezifanele uma ufuna ukubhujiswa kwamafayela okuthembekile ngempela. Kubalulekile ukuhlukanisa phakathi susa ngokunengqondo (Udoti, izinqamuleli, i-Explorer) kanye ukubhala ngaphezulu kobukhosi kokuqukethwe.

Indlela elula ukusebenzisa imenyu yokuqukethwe: chofoza kwesokudla kufayela bese ukhetha okuthi "Susa." Lokhu kuthumela ifayela ku-Recycle Bin. Ngesikhathi i-Recycle Bin isavuliwe, ungasebenzisa okuthi "Hlehlisa Susa" noma ubuyisele ifayela endaweni yalo yokuqala. Kuleli qophelo akukho ukusula okuphumelelayo.

Uma ukhipha i-Recycle Bin, i-Windows imaka leso sikhala njengesitholakalayo, kodwa njengoba sesivele sazi, okuqukethwe kuhlala kungabuyiselwa kuze kube yilapho uhlelo luyibhala ngaphezulu ngedatha entsha. Kwenzeka into efanayo uma ususa ngqo usebenzisa izinqamuleli zekhibhodi, njengenhlanganisela ye-Shift + Delete, edlula i-Recycle Bin bese imaka ifayela njengelisusiwe ngaphandle kokulidlula.

Futhi kusuka ku-ribbon ye-File Explorer, kuthebhu yasekhaya, ungakhetha okuthi "Susa" futhi, kwezinye izimo, "Susa unomphela." Futhi, le nketho Iyadlula i-Recycle Bin kodwa ayenzi ukusula okuphephileImane nje yenza ukusula okunengqondo okuqondile.

Ukuze uthole imisebenzi enamandla kakhulu, ungasebenzisa umyalo noma i-PowerShell. del /FC:\path\file Kusukela kumyalo osheshayo, kuphoqa ukususwa noma ngabe ifayela limakwe njengelifundwayo kuphela, kodwa alisayibhali idatha ngaphezulu. Nge-PowerShell, Susa-Into -Indlela C:\indlela\ifayela -I-Recurse Ivumela ukususwa kwamafayela namafolda wonke, kuyilapho iwashiya esengozini yokululama uma nje engabhalwa kabusha ngokoqobo.

Ukusetshenziswa kwamathuluzi okubhubhisa amafayela: SDelete nokunye okufanayo

Ukuze siqhubekele phambili futhi siqinisekise ukuthi idatha ichotshoziwe ngempela, kunezinsiza ezithile ezifana I-SDelete (Susa Ngokuphepha), ingxenye yephakheji ye-Microsoft SysInternals. Lolu hlelo lomugqa wemiyalo luhloselwe bhala kabusha indawo yangempela lapho ifayela lihlala khona noma ukuhlanza isikhala samahhala seyunithi.

Uma usulande i-SDelete futhi wakhipha ifayela le-ZIP, uzothola i-sdelete.exe esebenzisekayo. Kusukela efasiteleni lesaziso somyalo elinezimvume ezifanele, ungasebenzisa imiyalo efana igama lefayela le-sdelete ukususa ifayela elithile, noma ukwengeza amapharamitha afana nalawa -s -q ukuze isebenze kumafolda ngokuphindaphindiwe nangokuthula.

Uma ufuna ukuqinisekisa ukuthi yonke indawo yediski yamahhala ihlanziwe, ungaqala sdelete -zLo myalo unesibopho sokubhala idatha ezindaweni ezimakwe njengezikhululekile, ukuze izinsalela zamafayela asuliwe ngaphambilini ziyabhujiswaKuwusizo kakhulu ngemva kokususa ngesandla inani elikhulu lolwazi ongafuni ukuthi luphinde lutholakale.

I-SDelete iphinde inikeze ithuba lokulawula inani lamaphasi ezisebenza endaweni. Ukusebenzisa, isibonelo, ifayela le-sdelete.exe -p 5 Ungabhala ngaphezulu indawo lapho ifayela lalikhona izikhathi ezinhlanu. Uma ubhala ngaphezulu izikhathi eziningi, kuzoba nzima kakhulu ukulibuyisela, yize inqubo izothatha isikhathi eside.

Kubalulekile ukukhumbula ukuthi umphumela we-SDelete eqinisekile futhi engenakuhlehliswaAkufanele isetshenziswe kalula, futhi kufanele uhlale unezipele zanoma yiluphi ulwazi ofuna ukulugcina, ngoba uma selubhaliwe ngeke kube nendlela enengqondo yokuluthola.

Isofthiwe eyengeziwe yokususa nokulungisa okuphephile

Ngaphandle kwe-Eraser kanye ne-SDelete, kunezinye amathuluzi amahhala nakhokhelwayo aklanyelwe ukuhlanza amadiski ngokuphephile. Izinhlelo ezifana ne- I-DBAN (Darik's Boot and Nuke) Zilayishwa kusuka ku-CD noma ku-USB futhi zivumela susa konke okuqukethwe kwedrayivu eyodwa noma ngaphezulu ukusebenzisa ama-algorithms ahlukene okusula (i-DoD 5220.22-M, i-Gutmann, i-PRNG, njll.), okuwusizo kakhulu uma ufuna ukushiya umshini ulungele ukuphinda usetshenziswe noma udluliselwe komunye umuntu.

Ezinye izinsiza, njenge CCleaner noma ezinye izithuthukisi zesistimu, faka amamojula e- susa isikhala samahhala namafayela esikhashanaLokhu kuthuthukisa nokusebenza kwesistimu ngokususa i-bloatware nezinhlelo ezingadingekile. Izixazululo ezifana ne-Avast Cleanup, isibonelo, zihlanganisa ukuhlanza amafayela angcolile edijithali nokumisa izinhlelo zokusebenza ezidinga izinsiza eziningi.

Emkhakheni wezinkampani, kukhona amathuluzi okubethela kanye nokuphatha idatha njenge I-Atlansys Bastion Pro (kusatshalaliswa neminye imikhiqizo yokuphepha) okuthi, ngaphezu kokubethela amadrayivu nezinhlu zemibhalo, kunikeze imisebenzi ye ukususwa kwe-cryptographic okuqinisekisiweNgemenyu yokuqukethwe kwe-Explorer, kungenzeka ukukhetha amafayela noma amafolda bese uwa-oda ukuze uwasuse ngokuphephile, okubonisa inqubekela phambili eningiliziwe futhi okukuvumela ukuthi umise inqubo, yize kungekho ithuba lokubuyisa lokho osekubhujisiwe kakade.

Ukukhetha phakathi kwabo kuzoncika ekutheni uyafuna yini susa amafayela akhululekile, amafolda aphelele, isikhala samahhala noma amadiski aphelele; uhlobo lwedrayivu (i-HDD noma i-SSD) nokuthi ngabe iyindawo yasekhaya noma yobungcweti enezidingo zomthetho eziqinile.

Ukususa isikhala samahhala ngemiyalo ye-PowerShell ne-Windows

Nakuba ukususa amafayela nge-PowerShell, ngokwako, kungasho ukuthi idatha izobhujiswa unomphela, ungasebenzisa imisebenzi ethile ukuze bhala kabusha isikhala esikhululekileUmthombo ongaziwa kakhulu yimiyalo yokubethela ye-Windows eneziguquli ezithile, ezivumela ukubhala kuzo zonke izindawo ezimakwe njengezikhululekile kudrayivu ethile.

Ukugeleza okuvamile kuqukethe susa amafayela ngesandla kuqala (bese uthulula i-Recycle Bin ukuze i-Windows iphawule leso sikhala njengoba sitholakala) bese uqala inqubo egcwalisa zonke izindawo zamahhala ngedatha engahleliwe noma ama-zero, okwenza noma yimuphi umzamo wokubuyisela olandelayo ube nzima kakhulu.

Ukuze wenze lokhu, ungasebenzisa imiyalo evela ku-PowerShell console enamalungelo okuphatha asebenza ngesisekelo se-drive-by-drive, echaza uhlamvu lwe-drive oluhambisanayo. Inqubo ingathatha isikhathi eside kuma-drive amakhulu noma ama-drive anesikhala esiningi samahhala, kodwa uma isiphelile. cishe yonke iminonjana yamafayela asusiwe ibhalwe ngaphezulu.

Le ndlela ayithathi indawo yamathuluzi akhethekile ezimweni ezibucayi kakhulu, kodwa kumsebenzisi ojwayelekile iyindlela elula indlela enengqondo yokuqinisa ukuphepha ngaphandle kokufaka isofthiwe eyengeziwe, ikakhulukazi ngemva kokususa inqwaba yedatha yomuntu siqu.

Ukufometha, ukusetha kabusha i-PC, kanye nokusula uhlelo ngokuphelele

Omunye umbuzo ovamile ukuthi ngabe ukufometha idiski noma ukusebenzisa inketho ethi "Setha kabusha le PC" ku-Windows kuzoholela ku- ukususwa unomphela kwangempelaNgokuvamile, ifomethi esheshayo ihlela kabusha isakhiwo esinengqondo sohlelo lwefayela, kodwa Akubhali kabusha konke okuqukethweukuze eminye imininingwane isakwazi ukutholakala ngamathuluzi akhethekile.

Ku-Windows 10 no-11, umsebenzi wokusetha kabusha ukuvumela ukuthi ukhethe ukuthi "ugcine amafayela ami" noma "ususe konke." Ukukhetha "ukususa konke" kanye nokuvumela inketho yokuthi "Hlanza iyunithi" (esigabeni sezilungiselelo ezithuthukisiwe), uhlelo lwenza inqubo yokususa ejulile kakhulu, ehloselwe idatha ayikwazi ukubuyiselwa kalula.

Le nqubo iwusizo kakhulu uma uzothengisa noma uphana ngekhompyutha yonke futhi ungafuni ukuzikhathaza ngamathuluzi angaphandle. Kodwa-ke, kusho ukulahlekelwa yiyo yonke idatha yakho, izinhlelo, kanye nezilungiselelo, ngakho-ke kufanele ukwenze lokhu kusengaphambili. yenza amakhophi wesipele konke okudingayo ukuze uhlale usebenzisa enye indlela.

Endabeni yama-SSD anamuhla, abakhiqizi abaningi bafaka inketho "yokususa okuphephile" kumathuluzi abo okuphatha, okuthumela umyalo othize kudrayivu ukuze setha kabusha wonke amaseli ememori esimweni esifana nezilungiselelo zasefekthri. Kanye nokubethela idiski eligcwele, kungenye yezindlela ezinconywa kakhulu zokusula i-SSD ngaphandle kokusebenzisa ama-overwrite angapheli.

Yenza ngokuzenzakalelayo ukuhlanzwa kwamafayela esikhashana kanye ne-Recycle Bin ku-Windows

Inkinga ngamafayela esikhashana kanye nokugcwala kwe-Recycle Bin ukuthi Ziyaqoqana ngaphandle kokuqaphela thina....ukuba umthombo wegolide wolwazi kunoma yimuphi umhlaseli othola ukufinyelela kukhompyutha. I-Windows ifaka uhlelo "lwe-Storage Sense" ongalusebenzisa ukuze, ngezikhathi ezithile, Thulula ngokuzenzakalelayo i-Recycle Bin bese ususa amafayela esikhashana.

Ukuze ulungiselele lokhu, chofoza kwesokudla kudeskithophu, iya ku-"Izilungiselelo zokubonisa," bese uya ku-"Isistimu," bese ekugcineni uye ku-"Isitoreji." Uzobona inkinobho ekuvumela ukuthi uvumele ukususwa ngokuzenzakalelayo kokuqukethwe okungadingekile. Uma sekuvuliwe, iphaneli izovula lapho ungakhetha khona ukuthi uzoyihlanza kangaki i-Recycle Bin, amafayela ohlelo lokusebenza lwesikhashana, nezinye izinto ongasazidingi.

Lokhu kuzenzakalelayo kunephutha elicacile: lapho ifayela linyamalala ngale ndlela, Ngeke usakwazi ukubuyisa izinguqulo zangaphambilini noma amadokhumenti asuswe ngephutha.ngaphandle kokuthi unezipele zangaphandle. Yingakho kunconywa ukuhlanganisa lesi sici nenqubomgomo yokuvikela idatha. amakhophi wokulondoloza yedatha ebalulekile.

Ngesikhathi esifanayo, kunciphisa umkhondo wolwazi olusele ohlelweni, okwenza kube nzima nge-malware noma umhlaseli ukuluthola. izinsalela zemibhalo owawucabanga ukuthi azisasekhoAkuyona into "yamasosha" yokusula, kodwa kuyisinyathelo esihle sokugcina imfucuza yedijithali ilawulwa.

Ukubethela okugcwele kwediski kanye nokubhujiswa kokhiye: indlela enhle kakhulu

Isu elisebenza kahle kakhulu, ikakhulukazi ngama-SSD nemishini yesimanje, bhala ngemfihlo yonke idiski kusukela ekuqaleniNgale ndlela, noma ngabe umuntu uyakwazi ukuthola idrayivu ebonakalayo, ngeke akwazi ukufunda lutho ngaphandle kwenkinobho yokucisha ukubethela, ngoba idatha egciniwe ibethelwe ngokuphelele.

Ku-Windows ungasebenzisa amathuluzi afana nalawa Idrayivu Yobhalomfihlo i, ku-macOS FileVaultfuthi ku-Linux kuya kuzixazululo ezifana VeraCrypt noma i-LUKS. Okungcono kakhulu, lokhu kubethela kufanele kuvunyelwe. ngemuva nje kokufaka uhlelo lokusebenzaNgaphambi kokuthi uqale ukungena kumasevisi aku-inthanethi noma ukulondoloza amadokhumenti, ukugwema ukushiya izindawo ezibalulekile zingabethelwe.

Icebo lokusebenzisa ukubethela njengendlela yokubhubhisa evikelekile ukuthi, uma ufuna ukususa ikhompyutha noma idiski, Shintsha iphasiwedi yokubethela ibe yinde, engahleliwe. ukuthi awukwazi ukukhumbula nokususa wonke amarekhodi lapho uwagcine khona. Empeleni, lokho kufana nokubhubhisa ukhiye wesifuba: idatha isekhona, kodwa Akunakwenzeka ukuzichaza ngaphandle kwesihluthulelo.

Esimweni esithile sama-SSD, ukuhlanganisa ukubethela okugcwele nalokhu kubhujiswa okuyisihluthulelo kungenye yezinto ezibangela lokhu izindlela ezimbalwa ezilula neziphephile ngempela ukuqinisekisa ukuthi okuqukethwe akufinyeleleki, ngaphandle kokufaka isifiso sokubhala ngaphezulu amaphasi amaningi noma ukusebenzisa ukubhubhisa ngokoqobo.

Ukubhujiswa ngokomzimba: lapho ungakwazi ukukhokhela noma yiziphi izingozi

Kunezimo (izinhlangano zomphakathi, izinkampani ezinezimfihlo zokuhweba, iminyango ye-R&D, njll.) lapho ngisho nokuhlanganiswa kokubethela nokususa okunengqondo kungabhekwa njengokwanele, futhi inketho ekhethiwe yile izindlela ezibonakalayo zokubhubhisa ukwesekwaYilapho-ke izixazululo zemishini, ezishisayo, nezamakhemikhali zisebenza khona.

Ezingeni lomshini, yize isithombe sesando nesipikili siheha, akuqinisekisi ukuthi idatha ayitholakaliKunemishini ethile yokugunda izinsimbi yezimboni yama-hard drive aguqula ngokuphelele ama-plate, noma imishini yokushelela ekwazi ukususa ungqimba lwe-ferromagnetic olugcina ulwazi, okunciphisa noma yiliphi ithuba lokufunda.

Ensimini yokushisa, amayunithi asekelwe ekumbozweni kwe-ferromagnetic angafakwa emazingeni okushisa angaphezu kwalawo Iphuzu leCurieUma kwenzeka ama-chromium oxide asetshenziswa kwamanye amadiski, izinga lokushisa licishe libe ngu-113ºC; uma leli zinga lokushisa selifinyelelwe ngendlela elawulwayo (isibonelo, esithandweni somlilo), izinto zilahlekelwa yizimfanelo zazo zamagnetic futhi ulwazi lukhanseliwe ngempumelelo ukuthi yayiqukethe.

Ekugcineni, nansi indlela yamakhemikhali: izingxube ezinamandla kakhulu njengezakudala I-Aqua regia (ingxenye eyodwa ye-nitric acid kuya kwezingxenye ezintathu ze-hydrochloric acid egxilile) ziyakwazi qeda ngokuphelele izingxenye zensimbi kusuka ku-hard drive, kusulwe kokubili idatha kanye nendawo yokugcina idatha uqobo.

Lezi zinqubo, nakuba zinkulu, zinezinkinga ezisobala: Ziyingozi, ziyabiza, futhi zidinga izinsiza ezifanele (ukuvikela, ukungenisa umoya, imishini ethile). Lokhu kuvame ukugcinelwa izimo ezithile kanye nemithetho eqinile; kubasebenzisi abaningi kanye nezinkampani, inhlanganisela enhle yokubethela, amathuluzi okusula avikelekile, kanye nezinqubomgomo zokuphatha umjikelezo wokuphila kwedivayisi ezicacile zanele.

Uma kwenziwa isinqumo sokuphinda kusetshenziswe amakhompyutha esikhundleni sokuwabhubhisa, kubalulekile ukuthi kuhlolwe ngokucophelela kusengaphambili. ukubhalwa kabusha okuphelele kwedatha (kungaba ngokusebenzisa amathuluzi okususa noma ngokubethela nokuvuselela ukhiye) ukuze umsebenzisi omusha angakwazi, ngengozi noma ngamabomu, ukufinyelela amafayela omnikazi wangaphambilini.

Ekugcineni, isihluthulelo ukuqonda ukuthi ifayela alinyamalali ngomlingo uma lisuswa; lishiya umkhondo ongahlala isikhathi eside. Ukukhetha indlela efanele—kungaba ukususwa okunengqondo, ukubhala ngaphezulu, ukubethela, izinsiza ezikhethekile, noma, ezimweni ezimbi kakhulu, ukubhujiswa ngokomzimba—yikona okwenza umehluko. "phuma endleleni" elula futhi ukulahla okuphephile ngempela yedatha yakho.
