exFAT iri faira sisitimu yakagadzirwa neMicrosoft kugadzirisa kusakwana kweFAT32 kana ichishandiswa mumahara makuru emagetsi anotyaira. Tsigiro yeiyo exFAT faira system yakaonekwa muWindows Vista Service Pack 1 uye Windows XP ine Service Pack 2.
Yakakura saizi saizi ichienzaniswa neFAT32 yakawedzerwa kubva ku4GB kusvika pa16 exabytes, kurambidzwa pahukuru hwekuparadzanisa saizi ye32GB kwakabviswa kudzikisa kupatsanuka, pamwe neyemahara block bitmap yakaunzwa kumhanya, muganho wehuwandu hwemafaira mune dhairekitori wakakwidziridzwa kusvika zviuru makumi matanhatu nezvishanu, kugona kwekuchengetedza ACL kwakapihwa.
Sezvaunoziva, kusvikira munguva pfupi yapfuura kushandiswa kweiyi faira system muLinux kwaive kuburikidza kumisikidzwa kwerutsigiro rwayo nerubatsiro rwe kushandiswa kwesoftware kwakagadzirwa nevechitatu mapato. Nekuti kuitiswa kwaive kwakavanzika.
Asi kusvikira mwedzi mishoma yapfuura Microsoft yakaburitsa zvirevo zviripo pachena uye yakaita kuti zvikwanise kushandisa exFAT patents yeLinux mahara.
Kunyange zvakadaro kufamba uku neMicrosoft hakuna kuburitsa kodhi yekodhi, zvazvinoita urikungoregedza exFAT kodzero dzekushandisa uye kuchengetedza chero chinangwa chekuda kana kudana pamwe chete nenhengo dzeOpen Invention Network (OIN).
Kure kure neizvozvo, mutyairi we exFAT akagadzirwawo neSamsung uye iyo yakurudzira kuisa muLinux kernel seti yemakemikari pamwe nekumisikidzwa kweiyo nyowani exFAT mutyairi, zvichibva pakodhi yekodhi "sdfat" ikozvino, yakagadzirirwa firmware ye Samsung Android smartphones.
Isu tinoronga kubata kuburitswa uku sezasi-kumusoro ramangwana rekodhi rakabatanidzwa kamwe chete, nezvose zvitsva maficha uye zvigadziriso zvebug zvinotanga kutanga.
Kutonga nedata riripo, iyo kodhi nyowani inosanganisira mamwe mashandiro nemetadata uye inosanganisira kururamisa kwakati wandei zvikanganiso. Kusvikira ikozvino, inongoshandiswa chete pane Samsung Android zvishandiso.
Mukuita uku kwakapihwa neSamsung, yakawedzerwa kuchikamu chekuyedza »staging» ("Vatyairi / staging /") Linux kernel 5.4 zvinoenderana nekodhi yechinyakare (vhezheni 1.2.9).
Kunyangwe vanofarira Android firmware vanodhiraivha mutyairi mutsva sdFAT (2.x), asi Samsung yakafunga kuunza uyu mutyairi mune huru Linux kernel iri yega.
Parizvino kurongwa kwakarongwa neSamsung kwagamuchira mvumo dzinoverengeka kubva kune vakakurumbira veLinux kernel vanogadzira.
Saka nekudaro, uchipiwa iyo nguva, kuchine mikana yekuti uyu mutyairi weFFAT anogona kutsiva iyezvino prep exFAT mutyairi weLinux 5.6 kana iyo yasara kodhi ongororo ikafamba zvakanaka.
Zvichienzaniswa nesdatat mutyairi anotumirwa mumafonis, shanduko dzinotevera dzaitwa:
- Inofananidzwa neye exFAT mutyairi akambowedzerwa kune kernel, mutyairi mutsva anopa kuwedzera kwekuita angangoita 10%.
- Iyo kodhi ine kuiswa kweVFAT FS yabviswa, sezvo ino sisitimu yefaira yatove yakatsigirwa zvakasiyana muiyo kernel (fs / mafuta).
- Anodzora zita rakachinjirwa ku exfat
- Code yakadzorerwa-invoice uye yakacheneswa kuti inyatsobatanidzwa mune yekumusoro Linux shanduro uye uteedzere Linux kukodha maitiro
- Kugadziridza kwemetadata mashandiro, senge kusikwa kwefaira, faira system chinhu chekutsvaga (tsvaga), uye dhairekitori yemukati tsananguro (readdir) yakaitwa.
- Bugs akaonekwa panguva yekuwedzera kuyedzwa akagadziriswa.
Kana zvigamba zvikagamuchirwa, zvinozoverengerwa muLinux 5.6 kernel kodhi, ane bhuku rinotarisirwa mukati memwedzi miviri kana mitatu kusvika zvino. Kunyangwe kana dambudziko rikamuka, kuitiswa kweSamsung exFAT mutyairi kunogona kunonoka kuita vhezheni 2 yeLinux kernel.
Pakupedzisira, kana iwe uchida kuziva zvakawanda nezvenhau, pamwe nemaficha anowedzerwa mushanduro nyowani yeSamung exFAT mutyairi iri vhezheni 11 unogona kuzviita mu chinotevera chinongedzo.
