Bhala i-Pendrive evikelwe ku-Linux

Uma unememori khadi ye-SD, i-pendrive noma iyiphi i-disk yokugcina i-USB oyifunayo bhala vikelaKulesi sihloko sizokutshela igxathu negxathu nangendlela elula ukuthi ungakwenza kanjani. Futhi kukhona okuncane kokuvikelwa kokubhala okuvunyelwe abashayeli abathile, abaziwa ngokuthi «bhala ukuvikelwa kancane»Kuya ngokuthi iyasebenza yini ku-1 noma ku-0, izovumela ukubhalela iyunithi noma cha. Le ncanyana akufanele ididaniswe ne-WP yamarejista amafulegi ama-CPUs, avimbela ukubhala ngaphezulu ngokwakha inqubo yokufaka imfoloko kuzinhlelo ezifana ne-UNIX, ngaleyo ndlela ivikele inkumbulo enkulu ekubhalweni kwedatha. Noma kuthebhu ejwayelekile yokuvikela esiyithola kwamanye amakhadi e-SD noma kwimidiya yokugcina. Kulokhu sikhuluma ngokuvikelwa okwenziwa kwimidiya yesibili yokugcina.

Ngenkathi isilawuli se- indawo yokugcina Imemori khadi ye-USB noma ye-SD, noma yini, ukuthola ukuthi le bit iyasebenza, umshayeli uzovimbela i-kernel eku-odeni i-oda lokubhala ngakho-ke izokwazi ukufunda okuqukethwe kuphela. Kuyasebenza impela lapho sigcina idatha esingafuni ukuyiguqula, sigweme ukubhala noma ukususa ngephutha. Kepha uma enye yalezi zindaba ezivikelwe iwele ezandleni zethu futhi singazi ngobukhona bale nto, singachitha amahora sicabanga ukuthi iyunithi lethu lilimele, noma ukukhulisa nokunciphisa ithebhu encane amanye amapayipi noma amakhadi we-SD okufanele zivikele ngaphandle kwanoma yimuphi umphumela. (Khiya / Vula) ...

Khweza imidiya yokufunda kuphela noma yokubhala kuphela:

Yize kungeyona into esiyifunayo nge-Writ Protection Bit, futhi singathola ukuthi umuntu osebenzisayo ubelokhu ekhona ngokuzenzakalela noma ngesandla kufakwa ukufundwa kuphela, ngakho-ke ngeke sibe namandla okubhala kuyo. Okuthile kwezinye izimo kungacasula kakhulu futhi kusivikele ekuguquleni noma ekugcineni izinto. Yebo, isixazululo salokhu silula.

I-athikili ehlobene:

Khubaza isitoreji se-USB ku-Linux

Isibonelo, uma kufayela le- / etc / fstab idivayisi ilungiselelwe ukukhweza ngokuzenzakalela ngenketho ro (funda kuphela) noma uma siyifakile ngomyalo:

sudo mount -o ro /dev/sda /mnt

Esimweni esinjalo singafunda kuphela i- / dev / sda device kuleli cala ibekwe endaweni / mnt mount point. Ukuze sikwazi ukuyibhalela futhi:

sudo mount -o remount,rw /dev/sda /mnt

Uma kwenzeka le ndlela ingakusebenzeli, lapho-ke kuzoba ngoba okuncanyana esikhulume ngakho kuyasebenza, yingakho kuzofanele sisebenzise ithuluzi esilethula ngezansi.

Yini i-hdparm?

Umyalo i-hdparm iyithuluzi elisezingeni eliphansi esebenza njengesixhumi esibonakalayo phakathi kwabashayeli abahlukahlukene be-Linux kernel nemidiya yesitoreji se-SATA / PATA / SAS kusetshenziswa umtapo wolwazi we-libata, kanye nemidiya yakudala ye-IDE. Khumbula ukuthi izilawuli eziningi zemidiya yesitoreji se-USB, kufaka phakathi abafundi bamakhadi njenge-SD, nabo basebenzisa lolu hlobo lwesilawuli ukusebenza, ngakho-ke futhi luyahambisana nabo.

Su i-syntax eyisisekelo es:

i-hdparm [izinketho] [idivayisi]

Nezipho izinketho eziningi ozosebenza ngayo, yize ngingakutusi ukuthi uyisebenzise uma ungazi ukuthi wenzani kahle, ngoba ukuba yithuluzi elisezingeni eliphansi ungalimaza kakhulu idivayisi yakho, ngokwesibonelo uma sisebenzisa ezinye izindlela ezibucayi njenge -B. Kepha ngizokutshela ukuthi phakathi kwezinketho zayo kukhona ezinye ezithakazelisa njenge:

• Thola i- ukumisa wediski:

sudo hdparm /dev/sdd

• Khombisa ifayili le- ukuhlonza wediski:

 sudo hdparm -i /dev/sdd 

• Bheka izikhathi zokufunda ze-buffer ne-cache:

sudo hdparm -t /dev/sdd
sudo hdparm -T /dev/sdd

Khumbula njalo ukusebenzisa amalungelo, okungukuthi, ziqalise njengomsebenzisi wezimpande noma ubeka iSudo phambi kwazo noma zingasebenzi ...

Susa bese usetha kancane ukuvikelwa kwememori nge-hdparm:

Lapho ithuluzi le-hdparm selaziwa, singasebenzisa -r inketho esingabheka ngayo isimo salesi sikhala ngomyalo olula. Ukuze senze lokhu, sidinga kuphela ukwazi igama lomzimba wedivayisi yethu yokugcina. Isibonelo, uma / dev / sdd bebiziwe, kuleso simo singasebenzisa:

 sudo hdparm -r /dev/sdd 

Futhi inani le-bit elishiwoyo lizokhonjiswa esikrinini. Uma inani lalo lingu-1 lokho kusho ukuthi imodi iyasebenza Funda kuphela noma kufundwa kuphela, noma ngamanye amagama, indlela yokubhala ivikela iyasebenza futhi ngeke ukwazi ukubhala noma yini enkumbulweni. Ukuyicima noma ukuguqula kancane, kufanele wenze okulandelayo:

sudo hdparm -r0 /dev/sdd

Futhi manje uma senza umyalo wokuqala futhi sisebenzisa umbuso sizobona ukuthi ubuyele ku-0, ngakho-ke imodi ye-readonly icishiwe noma ayisebenzi. Uma kwenzeka ufuna ukuyibuyisela esimweni esisebenzayo, sebenzisa inketho -r1 Esikhundleni se -r0 futhi ngomumo. Ngokwesibonelo:

sudo hdparm -r1 /dev/sdd

Lokho kulula vumela noma khubaza lokhu kancane. Ayinayo imfihlakalo eningi kakhulu kodwa kulabo abangakwazi lokhu kungaba yikhanda uma kukhulunywa ngokungazivikeli imithombo yezindaba zabo zokugcina.

Ngiyethemba ukuthi kukusizile futhi manje usuyazi ukuthi ungayenza kanjani i-pendrive evikelwe ukubhala, ungakhohlwa shiya umbono wakho...
