    For the paranoid - from a privacy POV, yes. Harder to recover the old "gone" files contents. Other than that - no.

    (BTW, CCleaner fails miserably in this regard, get something else to do the job.)

    As far as I know, there will be no gain in performance by wiping free space. Wiping free space obfuscates (overwrites in an effort to hide) any data that might be left on the free space. This "old" data is not recognized by Windows, Linux, or Mac unless one uses a special program whose purpose is to recover these data fragments. Hence, wiping free space becomes a privacy issue and not a performance issue.

    Free space consolidation and wiping free space are two completely different procedures. Wiping the free space will not help you to get better performance or better defrag results. It will just make harder for others ( and/or you ) to recover data from the disk.

    In a previous post of yours you have said that you did a "consolidate defrag". I believe that for your defrag software "consolidate defrag" is free space consolidation. So you have already done that.

    Performance wise there is no need to wipe before restoring an image. Specially if you create sector by sector images then it's absolutely not needed to wipe.
    In general there is only need to wipe free space for privacy reasons.

    During free space consolidation your defrag software will move all the files/directories so you'll get a solid free space. If you could virtually see you hd you could see a space where all your files are gathered and an empty space ( consolidated free space ).

    Also check this pdf if you want to read something more about performance of free space consolidation ( which I repeat has nothing to do with wiping free space): http://www.perfectdisk.com/user_data/white_papers/pd2008_impactoffreespaceconsolidation.pdf
