When a file is copied from a HD to either a USB memory or CDROM, does it take along the slack space that was part of the orginal file? Or is it a bit-by-bit copy of just the orginal file? If this is the case, at what version of Windows was the slack space no longer copied? Is this documentented (i.e. KB article, technet, etc.)? Thanks TomThomas Talley

Compared with FAT32, NTFS has been improved a lot for the slack space part. So I think it would be much better in the future. After some research, so far I think no documents for what you are expecting.Thanks Zero Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Still seeking a reference that will articulate what data, if any, would be carried over due to slack space when coping a file from a hard drive to USB memory or CD/DVD media. It is critical to determine if any unintended information would be copied to the external media. Thomas Talley
