Get file offset on disk/cluster number
I need to get any information about where the file is physically located on the NTFS disk. Absolute offset, cluster ID..anything. I need to scan the disk twice, once to get allocated files and one more time I'll need to open partition directly in RAW mode and try to find the rest of data (from deleted files). I need a way to understand that the data I found is the same as the data I've already handled previously as file. As I'm scanning disk in raw mode, the offset of the data I found can be somehow converted to the offset of the file (having information about disk geometry). Is there any way
