1/ file record size
2/ ntfsck on reactos/windows
3/ ntfs index (directories)
1/
As I had a problem using my tool on my home computer, I discovered
The fileRecordSize=1024 done when ??? =0xf6 is not good.
I believe The File Record Size stored in each (first)
record is a better value.
2/ According to the relative poor documentation on ntfs, I believ that a ntfsck
tool is (for now) mor important tahn a ntfs driver.
Such a tool should work both under reacto and under windows.
It will verify both that the ntfs fs is compatible with ntfsck and ntfsck is
compatible with ntfs fs, doing lots of checks.
MoreOver, such a tool should allow interact with windows: (make an operation
with windows, and verify with the tool how data have changed).
3/
I'd like to work on such a tool, however I am confused by directories and
indexes, as the attributes $INDEX_ROOT (0x90) and $INDEX_ALLOCATION (0xA0)
are not very well understood by me.
This deal with inode 5 (the main directory).
Can somebody give me a piece of information/help?
