Without attempting this yourself and relating your own experience, how
can you verify this belief?
I've examined the separated parts of a 3.5" cookie and two things are
immediately apparent to me. The first is that the metal hub's profile
is not straight-edged, but conical, so any re-attachment would be
self-centering. The second is that the residue of the adhesive used to
attach the media to the hub is quite visible, so you do have a
In any case, if done carefully, and preferably with another hub that has
the mirror profile of the first, I don't imagine any placement error
should be worse than that of the square spindle hole in the hub itself.
Since you require proof of "several" 3.5" attempts being successful,
I'll attempt this when there's money involved for my time.
Until then, we're both only speculating. If I attempt to demonstrate my
assertion and succeed, I'm getting the feeling that you'll still be an
Did the forensics community or the NML ever comment on the subject?
