Ok, I can give you another answer, more detailed, but I have no idea, how much
more usable, as I'm no expert in low-level NTFS specifics.
I can imagine Cygwin tools being able to read, store and restore OS-specific
file attributes, but I doubt these attributes have any use outside OS.
I.e., I was unable to use NTFS junction point under Linux. Junction was to a
second partition of the same drive, so there's no possibility of missing
partitions or similar mistakes on my part. ntfs-3g just doesn't work the same
way, as native Windows NTFS driver.
Oh, also... Are you sure you have full low-level access to partition in
question? I.e., it is not blocked by antivirus, or UAC?
