Nyaya kubva pakuita sevhisi: Netsaona yakafomatidzwa flash drive

Mutengi wacho akauya achimhanya akabata maoko: * “Tenzi, takatora mapfuti ebvunzo tisati tatenga D810, uye mutengesi netsaona. akafomatidza kadhi mukamera chaimo! Ndakatora mafaira eNEF ndichishandisa Recuva, asi mapurogiramu haaone EXIF. Mileage yarasika?"*.

Usatya. Kunyangwe akafomatirwa kana kukuvadzwa zvishoma makadhi ememori anogona kubvisa MakerNote masevhisi tag.

Kumutsiridza MakerNote bytes kunoshanda sei?

1. Sei chirongwa chekudzorera chichiwanzovhiringidza misoro:Zvishandiso zvakaita seRecuva kana R-Studio dzosa chimiro chemuviri, asi dzimwe nguva kurasikirwa neTIFF musoro byte offset (`0x4949` kana `0x4D4D`).
2. Yedu yakadzika parsing algorithm:Kunyanya kuzviitiko zvakadaro, sevhisi yedu yepamhepo inosanganisira basa rekuongorora bhinari faira nemasaini. Iyo algorithm haivimbe nemusoro, asi inotarisa siginecha `Nikon\x00\x02` muviri wese wefuremu yakakuvadzwa.

Chii chekuita kana iyo faira isingavhure semufananidzo?

Kunyangwe iyo yakashatiswa `.NEF` faira rikasaoneka pachiratidziro semufananidzo, iyo MakerNote binary chikamu (apo tag 0x00A7) inoramba isina kukuvara mu90% yemakesi! Isa faira "rakatyoka" rakadaro kushumiro yedu - tichariburitsa zvakadaro kupfura chaiko kwekuvhara.
