ntfs-3gドライバが変更ログを実装しているかどうかを知っている人はいますか?公式ホームページを確認してみましたが、関連情報が見つかりませんでした。米海軍。
答え1
文書がたくさん見つかりませんでした。米海軍+ ntfs-3g、しかし、以下でntfs-3gのソースコードをチェックしてください。include/ntfs-3g/layout.h、次を見つけました。
/**
* struct NTFS_RECORD -
*
* The Update Sequence Array (usa) is an array of the u16 values which belong
* to the end of each sector protected by the update sequence record in which
* this array is contained. Note that the first entry is the Update Sequence
* Number (usn), a cyclic counter of how many times the protected record has
* been written to disk. The values 0 and -1 (ie. 0xffff) are not used. All
* last u16's of each sector have to be equal to the usn (during reading) or
* are set to it (during writing). If they are not, an incomplete multi sector
* transfer has occurred when the data was written.
* The maximum size for the update sequence array is fixed to:
* maximum size = usa_ofs + (usa_count * 2) = 510 bytes
* The 510 bytes comes from the fact that the last u16 in the array has to
* (obviously) finish before the last u16 of the first 512-byte sector.
* This formula can be used as a consistency check in that usa_ofs +
* (usa_count * 2) has to be less than or equal to 510.

どうやら米海軍を利用しているようですが、適切な入手方法がわかりません。まず、NTFS_RECORDの使い方を理解し、そこからAPIを見つけようとします。
