A.  PLATFORMS AND WINDOWS[R] VERSIONS SUPPORTED
===============================================

Diskeeper runs on the Intel[R] x86 platform (including compatible 
CPUs from other manufacturers) running Windows Server[TM] 2003, 
Windows XP, or Windows 2000. 

The Windows versions supported vary by Diskeeper edition. 
See the Table of Supported Operating Systems later in this 
document for a chart of the different Diskeeper editions and 
the Windows versions each supports.

Note that x64 versions of Diskeeper will only install on x64 
editions of Windows.


B.  OVERVIEW OF DISKEEPER 2007
==============================

The term "Paradigm Shift" is somewhat overused when describing 
technical breakthroughs, but Diskeeper 2007 does indeed 
represent a major shift in the way you will improve the 
performance and reliability of your computers. For over a 
decade, Diskeeper has led the way in Windows system 
defragmentation technology, but Diskeeper 2007 takes such 
a significant step forward that paradigm shift is truly 
the most appropriate term to describe it.

Whether you’ve used Diskeeper before or not, you may already be 
familiar with some of its features, but Diskeeper 2007 
represents a major milestone in the progression of Diskeeper 
development. New users will find Diskeeper to be easy to use, 
yet comprehensive in its capabilities. Experienced Diskeeper 
users will see major changes, yet still recognize familiar 
features, presented in a new, more streamlined way. This list 
gives a summary of what’s new in this version.

o  Automatic Defragmentation

   Diskeeper has made its reputation with the trademarked phrase 
   “Set It and Forget It”[R], meaning that once Diskeeper is 
   installed, you can simply forget about it. Defragmentation was 
   taken care of automatically and your computer was kept at peak 
   performance all the time. 

   However, times have changed. Disk drives have grown huge. And, 
   with the growth of disk drives has come an explosion in the 
   size and number of files stored on disk drives. With terabyte 
   drives (a trillion bytes) now easily available and smaller 
   drives selling for very little money, you can store a LOT of 
   stuff -- practically everything. And file sizes are continuing 
   to increase as well. Documents with embedded graphics, large 
   presentations, scanned images, digital photos, MP3 music files 
   and even whole TV shows and movies are now residing on hard 
   drives. The vast quantities of these and their inordinate size 
   present new challenges for computer performance and make 
   defragmentation more critical than ever. 

   As disks have grown bigger and files have grown larger and 
   more numerous, defragmentation is required more and more often 
   to maintain a computer’s performance. While it used to be 
   sufficient to defragment once a week, it eventually became 
   necessary to defragment daily. Today, even daily defragmentation 
   is not enough. An hour’s production activity can seriously 
   degrade performance.

   But scheduling a defragmenter to run every hour is scary to 
   performance-conscious System Administrators and computer users. 
   Even with features like I/O Smart[TM] and selectable run 
   priorities, they are reluctant to run a defragmenter in the 
   middle of the workday.

   The answer is our new InvisiTasking[TM] technology. 
   InvisiTasking uses a proprietary technique developed in our 
   research lab to carefully monitor resource consumption on a 
   Windows computer system and inject Diskeeper processing into 
   the unused portions -- and only into the unused portions. 
   InvisiTasking is so good that it is all but impossible to even 
   detect whether Diskeeper is running. That means Diskeeper can 
   run all the time. With InvisiTasking there is no reason to 
   schedule defragmentation. In fact, scheduling defragmentation 
   worsens performance by delaying the improvement that 
   defragmentation brings. Diskeeper with InvisiTasking means a 
   computer performs at peak all the time, around the clock, not 
   just for a few minutes after each scheduled defragmentation run. 

   The Dashboard tab in the Diskeeper display includes a real-time 
   graph showing the idle resources on your computer, and the small 
   portion of those unused idle resources used by Diskeeper with 
   InvisiTasking. (Note that the graph also shows resources used 
   when Diskeeper is run manually.) Now, you may be skeptical at 
   first and find it hard to believe InvisiTasking has virtually 
   no impact on system overhead. For this reason, you can specify 
   times when Diskeeper is prevented from running at all. Eventually, 
   we are sure you’ll be convinced, and lock-out scheduling will be 
   forgotten.  The scheduling era is over, and the era of truly 
   automatic defragmentation has begun. 


o  I-FAAST[TM] 2.0

   Introduced in Diskeeper 10, and refined in Diskeeper 2007, the 
   second generation of Intelligent File Access Acceleration 
   Sequencing Technology (I-FAAST) goes beyond “normal” 
   defragmentation to speed up your file access and creation 
   times. Traditionally, a defragmenter like Diskeeper could 
   restore the performance of a computer to like new condition. 
   I-FAAST, however, can improve the computer’s performance to 
   better than new! 

   I-FAAST improves file access and creation by up to 80% 
   (average 10%-20%). This is the first industry implementation 
   of “Disk Performance Calibration”, the modern evolution of 
   the outdated and inconclusive disk optimization strategies of 
   the past. 

   When I-FAAST is enabled, Diskeeper runs specially-engineered 
   benchmarks on your disk volumes to learn their performance 
   characteristics. Diskeeper then transparently monitors volumes 
   for file access frequency on an ongoing basis to determine 
   which files are requested most often. Special analysis 
   techniques prevent Diskeeper from being “fooled” by files that 
   have been recently accessed. 

   Using newly-developed technology, Diskeeper sequences the files 
   to take best advantage of both the logical characteristics and 
   physical characteristics of the volume. The sequencing process 
   is integrated with background defragmentation, so it's 
   virtually transparent to you. 

   I-FAAST intelligence allows Diskeeper to adapt to changing 
   situations -— so if the demands on a given system change, 
   Diskeeper automatically adjusts its behavior accordingly. 

   This feature is included in Diskeeper EnterpriseServer, 
   Diskeeper Server and Diskeeper Pro Premier.


C.  CHANGES IN DISKEEPER 2007
=============================

Diskeeper 2007 has changed considerably  compared to previous 
Diskeeper versions. Here is a summary:

o  Based on usability studies, the Diskeeper console has been 
   further refined to reduce the number of steps necessary to 
   perform a task, and to improve the overall user experience.

o  Primary and Secondary defragmentation jobs have been 
   replaced by Automatic Defragmentation. The new 
   InvisiTasking technology ensures no negative performance 
   impact on other processes and applications when Diskeeper 
   is running in Automatic defragmentation mode.

o  Due to the nature of Automatic Defragmentation, there is 
   no longer a need to schedule defragmentation jobs as was 
   done in Diskeeper 10. You can specify exclusion periods 
   when Automatic Defragmentation will NOT be allowed to run, 
   but since Automatic Defragmentation uses the new 
   InvisiTasking technology, it is no longer necessary (or 
   recommended) to schedule Diskeeper to run only during 
   the "off hours". Doing so will only increase the amount 
   of fragmentation on your volumes, thus impacting their 
   performance. Also, the different "defragmentation methods" 
   no longer exist, since Automatic Defragmentation has 
   replaced the need. (Note that selectable defragmentation 
   methods are still available for Manual Defragmentation 
   operations.)

o  The I-FAAST 2.0 engines have been refined to use 
   InvisiTasking technology and to provide advanced online 
   directory consolidation and improved boot optimization. 
   You can also now select specific files to be included 
   in the I-FAAST processing.

o  Terabyte Volume Engine[TM] 2.0 has been enhanced to use 
   the InvisiTasking technology, and to better consolidate 
   free space. The TVE[TM] is available in Diskeeper 
   EnterpriseServer.


D.  CHANGES IN THIS RELEASE
===========================

Diskeeper 2007 build 686 represents all the cumulative 
changes made as the result of testing to date.


E.  KNOWN ISSUES IN THIS RELEASE
================================

1.  Although Diskeeper itself is fully compliant with 
    Section 508 (accessibility) standards, 508 compliance is
    not yet fully implemented into the Diskeeper installation 
    procedure.    

2.  Some of the Diskeeper installation dialogs do not display 
    correctly on computers using the High Contrast Black display 
    setting under the Windows Accessibility Options. Note, however, 
    the Diskeeper console does display correctly on these computers.

3.  When running Diskeeper from the Windows command prompt, the /d 
    parameter is not an optional parameter; it is required. 



F.  INSTALLING DISKEEPER 
========================

Note: Make sure you are logged onto an account that is a member
of the Administrators group.

Diskeeper is available either as a downloaded self-extracting 
compressed file, or on CD-ROM. The following instructions
apply to both formats.

Follow these steps to install Diskeeper:

The Diskeeper installation is typically fast and simple. 
Here are the basic steps:

1.  Insert the Diskeeper CD-ROM into the appropriate drive on 
    your computer. (If you are installing from a downloaded 
    file, double-click the file you downloaded.)

2.  Follow the screens displayed, answering the questions 
    asked as prompted.

For more details about installing Diskeeper, see the "Diskeeper
Installation" chapter in the Diskeeper User's Manual.


G.  UNINSTALLING DISKEEPER
==========================

To uninstall Diskeeper, you must be logged into an account that 
is a member of the Administrators group. 

Follow these steps to completely remove and uninstall Diskeeper 
from your computer. Note that the controls may have slightly 
different names, depending on your version of Windows:

1.  From Control Panel, double click "Add/Remove Programs".

2.  Highlight the Diskeeper entry.

3.  Click Remove. This removes the Diskeeper program files 
    from your computer. In most cases, the Diskeeper 
    installation directory will not be removed.

4.  During the uninstall process, the Windows Disk Defragmenter 
    is restored to the state it was in before Diskeeper was 
    installed.

5.  Manually delete the Diskeeper installation directory if it 
    exists.

Note: If the MMC has been installed on your computer, it will 
not be removed when Diskeeper is uninstalled.
