Oh, I know all about those lies. I signed up for a demo of Diskeeper
once and they incessantly spammed me with claims of how it would make my
games and such run so much faster. And I thought false advertising is
illegal? Needless to say, I ended up putting a block on them sending me
email.

I'm not a newcomer. Been occasionally frequenting this group since 1994
or so. Yes, I have had conversations with you before and you never
called me rude before either.

Defraggler has the old style colored blocks so is even better to watch. :)

Diskkeeper are particularly bad at this - and they are well-known as
spammers. You can expect that a number of the defrag enthusiasts you
have come across are astroturfers - they are either directly or
indirectly in the pay of commercial forces pushing defragmentation
software (I'm not accusing any particular company of using these
tactics, but I do know that some do it). Look out in particular for
anyone recommending commercial products in a suspicious manner - if you
feel you /must/ defrag, stick to the windows built-in defragger, or use
one of the many free packages.

All too true. And many want to sell you some product, which makes
it even worse.

Interestingly, I recently stumbled over a case of a really
badly fragmented ext2 Linux filesystem or rather a bunch of
really fragmented files. This is so rare that there
is no current defragmenter, the respective project
was canceled AFAIK, because nobody needed it. The thing
that happened here is that some application created a large
sparse file and then filled it in in random places until full.
Defragging is still easy, just copy the file once and delete
the original. After scripting that, the problem is gone.

Indeed.

This falls under "magic" to me, i.e. people not understanding what
actually has which effect.

There are no good benchmarks for fragmentation and its
effect depends heavily on a lot of factors.
