Comment 2 for bug 243287

what i did is offline defragmentation, because i took the hard drive from my brother's computer to my computer, and defrag it by an USB connection.
The confusing thing is, when i'm copying with Windows, there are no such "system" blocks left, which described before.
I'll post the NTFS debug later there. please give me explanations later.
One question, will those "system" blocks gone after i delete the files, or they will keep standing there?
