let me try again... why would anyone want to use free 3rd party
software that rewrote their harddrive? that's dangerous stuff (yes of
course you should backup first - yeah everyone does that...) you would
want to use the package the OS provider gave you or a well known 3rd
party which many people use so that if there is an error, someone else
finds it not you. as mentioned in my previous email it's not clear
that degramentation beside bootup optimization is really worth the
effort these days..let's see some thoroughup tests first.
here's the posting..

Regarding your excellent experience, I'm afraid something slipped
through the cracks on this article.

you just measured how long the deframentation took????
Since there is an active controversy on whether disk defragmenting
these days with ntfs is really worth it - there have been a few studies
- financed by the software utilitiy companies, but its not clear they
represent real typical desktop usage (i'm not arguing that NTFS can't
be fragmented as some have alleged). And yes, Microsoft includes a
basic one with XP - probably mostly for the quick boot optimization not
full disk defrag. (strange, that it wasn't reviewed and tested as well
- it makes one think PC Mag is only interested in trumpeting
advertisers new products?
see some of the controversy:

It would be helpful to us readers if you performed testing on the
quality of the defragmentation results - various real world tests like
boot time, and loading normal programs to do tasks before and after the
defrags to see which if any measurably improved results. Otherwise we
are stuck with the possibility that this software is going towards the
faux RAM compressor or faux window tuneup apps.
In the past, Gibson's GRC Spinrite did noticibly improve disk access,
but technology has changed so that solution no longer applies.
Frankly I don't know if full disk defrags or special file placements
etc are useful or not these days - maybe a clone & file by file restore
would be better, and maybe due to usage patterns even that many not
result in any realistic improvement.
interesting background here on unbuffered sequential i/o in windows:
http://research.microsoft.com/barc/sequential_io/
Maybe the best solution is to get a new faster larger hardrive
occasionally and do a file by file restore to it for contiguous layout
and then you have the benefit of a prior drive you could store away as
an archive.
How about a followup story?
Just to clairify, here is PC Labs testing criteria, it's hard to see
how this testing was Appropriate.
Who is responsible for this poor review and testing? - Specifically a
name and title, because your name (Richard V. Dragan) was unfortunately
on the article.
Accurate means that the product is evaluated using test
methodologies based on technical research of the industry, our readers,
and experts in the field.
Appropriate means that product evaluation measurements are based on
metrics that are applicable for both individual and corporate
real-world use.
Reproducible means that test scenarios used in an evaluation can be
recreated at a later time, with results deviating not more than 5
percent from the original results.
Thanks for your consideration regarding this matter,

A lot of marketing speak here at the Diskkeeper site:
Why is it crucial to defrag your drives daily?
Disk fragmentation causes crashes, slowdowns, freeze-ups and even total
system failures. The number one reason for performance bottlenecks is
fragmentation. Even the best hardware will eventually slow down unless
the drive is defragmented daily.
The disk drive is by far the slowest of the three main components of
your computer: CPU, memory and disk. If the drive isn't defragmented
the fastest CPU in the world won't improve your system's performance,
because information from the disk simply can't be delivered fast
enough.
Manual defragmentation just isn't practical-who has time to defrag
every system, every day? Manual defragmentation is a break-fix
situation. Automatic defragmentation with Diskeeper, the Number One
Automatic Defragmenter, is the only true defrag solution. Diskeeper 9
uses "Set It and Forget It"® technology to defrag drives as needed,
keeping your systems running as fast as they did when they were
brand-new.
The various editions of Diskeeper run on the Intel® x86 platform
(including the Intel Pentium™ and Pentium-compatible CPUs from other
manufacturers) running Microsoft Windows XP (Professional / Home /
Tablet PC / Media Center editions), Windows 2000 (all Professional and
Server editions), Windows Server 2003 (all editions), Windows NT 4.0
(all Server and Workstation editions), and Windows 95 / 98 / Me. For
