editions of Windows. 

In compliance with Windows Server 2008 Logo Requirements, all 
custom actions performed by the Diskeeper installation procedure 
are described 
at http://files.diskeeper.com/CustomActionsList.htm.


B.  OVERVIEW OF DISKEEPER 2009
==============================

For over a decade, Diskeeper has led the way in Windows system 
defragmentation technology, and Diskeeper 2008 continues with 
the tradition of true Set It and Forget It[R] performance 
enhancement that is a hallmark of  the Diskeeper name. 

Whether you’ve used Diskeeper before or not, you may already be 
familiar with some of its features, but Diskeeper 2008 adds 
refinements to these  features, and a number of other core 
enhancements. New users will find Diskeeper to be easy to use, 
yet comprehensive in its capabilities. Experienced Diskeeper 
users will recognize familiar features, but see improvements 
in Diskeeper (and their system) performance. 

This list summarizes the most important features in the various 
editions. More information about each of these features is 
available in the Diskeeper Help system:

Automatic Operation
------------------- 

Diskeeper is designed to operate without your intervention. Simply 
install Diskeeper, then sit back and let it take care of the details. 
Of course, you can also run Diskeeper manually. (But you probably 
have better things to do with your time. That’s what Automatic 
Defragmentation with InvisiTasking[R] technology is for!) 

Diskeeper Family of Products
----------------------------

The Diskeeper family of products offers specialized automatic 
defragmentation of Windows operating systems ranging from Windows 
2000 through Windows XP, Windows Vista, Windows Home Server, and 
Windows Server 2008 Datacenter. 

Descriptive Console Interface 
-----------------------------

The Diskeeper console provides an intuitive and informative 
defragmentation experience. Common commands are grouped together 
in the Quick Launch pane, and a group of tabbed panes show you a 
wide variety of information. Diskeeper shows you the condition of 
your disks, and provides suggestions for improving or maintaining 
your disks. 

Performance and Volume Health Analysis 
--------------------------------------

Diskeeper collects and displays data regarding the performance 
and overall health of your volumes in the Dashboard tab. This 
information allows you to be more proactive in the management and 
maintenance of your computers. 

I-FAAST[R] Defragmentation
--------------------------

Intelligent File Access Acceleration Sequencing Technology 
(I-FAAST) improves file access/creation by up to 80% (average 
10%-20%) above and beyond the improvement provided by 
defragmentation alone. This is the first industry implementation 
of “Disk Performance Calibration”, the modern evolution of the 
outdated and inconclusive disk optimization strategies of the 
past. 

Frag Shield[R] 2.0 Technology
-----------------------------

One situation that can impair the performance and reliability 
of your computer is fragmentation of the Master File Table (MFT) 
on NTFS volumes and your paging files. Since the operating system 
relies heavily on the MFT and paging file, the effect of 
fragmentation is often much greater than when a normal file is 
fragmented. Frag Shield is the first and only technology to 
prevent system file fragmentation. No more need to run a manual 
and resource-intensive process. The Frag Shield MFT fragmentation 
prevention technology is now fully automatic and re-written to 
operate invisibly using InvisiTasking technology. 

Terabyte Volume Engine[TM] Defragmentation
------------------------------------------

A Diskeeper exclusive, the Terabyte Volume Engine (TVE) is 
designed to efficiently defragment extremely large (larger than 
60 GB) volumes. This feature is available in selected Diskeeper 
editions. 

Titan Defrag Engine [TM] Defragmentation
----------------------------------------

The Titan Defrag Engine is specially developed for the most 
massive data volumes ever created. Starting at volumes containing 
4 to 5 TB of data, the Titan Defrag Engine will complete the job 
even faster and more thoroughly than the TVE. The Titan Defrag 
Engine is the only defragmentation solution capable of handling 
10 TB, 20 TB and even greater amounts of data. 

Boot-Time Defragmentation
-------------------------

Defragment files at boot-time that cannot be moved safely when 
Windows is running.


Selectable Disk and CPU Priority
-------------------------------- 

You can set the disk and CPU priorities at which Manual 
Defragmentation jobs run. Note that priority changes are 
unnecessary when running Diskeeper in Automatic Defragmentation 
mode. 

Exclusion Lists
---------------

Diskeeper exclusion lists allow you to specify files and 
directories that will not be allowed to be processed by 
Diskeeper. 

Event Logging
-------------

Diskeeper records information about its activity in two ways. 
First, general information about previously-run defragmentation 
job is shown in the Log tab within the Diskeeper console. 
Additional information can also be stored in a log file. 
A wide variety of information can be saved for future reference. 

Simultaneous Analysis or Defragmentation Operations
---------------------------------------------------

You can analyze and/or defragment more than one disk volume at 
a time with Diskeeper. 

Command Line Operation
---------------------- 

You can use commands from the Windows Command Prompt or a batch 
file to control Diskeeper. 

Group Policy Support
--------------------

Diskeeper can be configured network-wide with the Group Policy 
Editor provided with Windows 2000 Server, Windows Server 2003, 
and Windows Server 2008. 

MOM/SCOM Support
----------------

Enterprise administrators can use the Diskeeper Management Pack, 
available separately from Diskeeper Corporation, to allow 
MOM/SCOM to monitor and manage Diskeeper installations deployed 
across their network. The Diskeeper Management Pack includes 
numerous alerts, reports, and the ability to manage and control 
Diskeeper settings and configurations, all via MOM/SCOM.


C.  CHANGES IN DISKEEPER 2009
=============================

Here is a summary of what’s new in this version:


o Improved InvisiTasking

In the past, extremely busy systems or programs that were always 
on and running in the background could hamper InvisiTasking and prevent 
it from acquiring sufficient resources to complete its job. New 
functionality in InvisiTasking allows it to be more assertive, while 
still guaranteeing completely invisible, zero-overhead, operations. 
Diskeeper can invisibly keep up with and complete defragmentation on 
a 24/7 high powered workstation or server, On typical desktops/laptops 
this also allows Diskeeper to operate in conjunction with 
always-on/idle-time tasks that run at lowest priority such as 
SETI@Home and similar programs. 


o MOM and SCOM Support

Microsoft Operations Manager (MOM) and System Center Operations 
Manager (SCOM) allow monitoring and management of numerous computers 
interconnected by one or more communications networks. Many products, 
such as Active Directory, Microsoft SQL Server, Microsoft Exchange 
Server, and MOM itself can be monitored. Enterprise administrators 
can now use the Diskeeper Management Pack, available separately 
from Diskeeper Corporation, to allow MOM/SCOM to monitor and manage 
Diskeeper installations deployed across their network. The Diskeeper 
Management Pack includes numerous alerts, reports, and the ability 
to manage and control Diskeeper settings and configurations, all 
via MOM/SCOM. 


o Titan Defrag Engine

The Titan Defrag Engine is the most powerful defragmentation engine 
ever built, eclipsing even the previous technological leader – the 
Terabyte Volume Engine (TVE). The Titan Defrag Engine is specially 
developed for the most massive data volumes ever created. Starting 
at volumes containing 4 to 5 TB of data, the Titan Defrag Engine 
will complete the job even faster and more thoroughly than the TVE. 
The new engine is the only defragmentation solution capable of 
handling 10 TB, 20 TB and even greater amounts of data. If you have 
servers managing massive amounts of data, the Titan Defrag Engine is 
your newfound performance solution. The Titan Defrag Engine is 
available in Diskeeper EnterpriseServer. 


o Expanded TVE Availability

Diskeeper pioneered the concept of specialized defragmentation 
algorithms for large volumes, and continues that effort in 
Diskeeper 2009. Previous versions of Diskeeper included the 
Terabyte Volume Engine (TVE), which was designed for volumes 
over 60 GB. However, the TVE was only available in Diskeeper 
EnterpriseServer.

Disk volume sizes have continued to increase, and now it’s not 
uncommon for even home systems to have volumes 1 TB or larger in 
size. In light of this, Diskeeper 2009 now includes the TVE in 
Diskeeper Pro Premier, HomeServer, and Server editions. Diskeeper 
EnterpriseServer now includes the new Titan Defrag Engine, the 
ultimate in industrial-strength defragmentation technology.


o Expanded I-FAAST Availability

Intelligent File Access Acceleration Sequencing Technology 
(I-FAAST) is now available in Diskeeper Professional. 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%). It is the first industry implementation of “Disk 
Performance Calibration”, the modern evolution of the outdated 
and inconclusive disk optimization strategies of the past. 

o Improved Free Space Consolidation

New free space consolidation engines now provide more complete 
consolidation of the free space on your disk volumes.


o HyperFast – Solid State Drive Optimization

Solid State Drive (SSD) technology promises faster and better 
performance than conventional hard disk drives. However, Microsoft 
Windows is not optimized for NAND Flash as a principal storage 
device, such as is used with SSDs. As a result, computers with 
SSD storage devices will eventually experience a very noticeable 
and dramatic performance deterioration (up to 80%), to the degree 
that they will operate much slower than they would with a hard 
disk. The new HyperFast SSD optimizer integrates seamlessly, and 
is specifically designed to eliminate SSD performance degradation, 
and restore performance to like-new conditions. 

Note: HyperFast is a separate product, sold in addition to 
Diskeeper. Contact your reseller or visit the Diskeeper Corporation 
website at www.diskeeper.com to purchase HyperFast and keep your 
SSD volumes running at peak levels.


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

1.  Support for System Center Operations Manager (SCOM) 2007 has been 
    added. 

2.  The Performance Report previously included in trialware versions of
    Diskeeper is now available in the full product. Click "View 
    Performance Report" in the Action menu to see the report.

3.  The Active Directory Group Policy template supplied with Diskeeper
    now supports the new ADMX template format.

4.  Diskeeper 2009 Server product will now install on Windows Server 
    2003/2008 DataCenter Server.

5.  The Default Defragmenter schedule on Vista machines will not 
    be disabled upon installation of Diskeeper 2009.


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.

4.  Note that these files are not removed when Diskeeper is 
    uninstalled:

    Productname.msi (for example, Diskeeper 2009 Server.msi)

    DKDesktopShortcut_A4ED7F98B2A54A06855C7E8804E8460E.exe 

    These files are open during the uninstallation process, but
    they can safely be deleted afterwards.

5.  When clicking links within Diskeeper that open web browsers, 
    Diskeeper typically launches whichever browser has been set 
    as the system default. However, on Windows Vista, Windows 
    Server 2003, or Windwows Server 2008, Internet Explorer is 
    opened, regardless of the system default setting.

6.  Under rare circumstances, an error message stating "Unhandled 
    Exception Error 0x0000005 Press "ESC" to reboot system" may
    be displayed when a Boot-Time defragmentation operation is in 
    progress. This message is displayed when the Boot-Time 
    defragmentation engine does not receive the expected data
    from the operating system. If this occurs, the Boot-Time
    engines safely stop any further processing, to ensure the 
    integrity of your system.

7.  When installing Diskeeper 2009 over an existing Diskeeper 
    2007 system, in some cases Diskeeper 2007 does not
    stop correctly. This can result in long completion times
    for the installation operation, or a crash of the Diskeeper 
    Service. The installation will complete successfully after 
    the Diskeeper 2007 Service is stopped.


F.  KNOWN INCOMPATIBILITIES
===========================

1.  Diskeeper will not run on disk volumes that are locked by 
    utilities such as CHKDSK or Scandisk.

2.  The Hercules Terminator AGP 128/3D "GLH" 8MB also does not 
    appear to display the full Boot-Time dialog, and thus appears 
    to hang when the "Pause to view screen after defragmentation" 
    option in the Diskeeper Boot-Time Properties as been enabled.

3.  The keyboard functions during a Boot-Time Defragmentation job 
    do not work on all combinations of hardware, HAL (hardware 
    abstraction layer), and operating systems. We are working to
    provide keyboard access from the greatest combination of 
    these elements, but if your system does not respond to the 
    keyboard functions during a boot-time, please report the 
    hardware configuration and full operating system version to 
    Diskeeper Corporation Technical Support at this address:

    (support@diskeeper.com). 

    Providing this information may help us determine why certain
    combinations of hardware and software cannot access the 
    keyboard functions during Boot-Time Defragmentation.

4.  Diskeeper is compatible with Roxio GoBack. Note, however, 
    that you should add the "gobackio.bin" file to the Diskeeper 
    exclusion list. After doing so, should be no problems 
    running GoBack along with Diskeeper.

5.  The free space figures displayed in the Diskeeper MMC snap-in 
    may not match those shown in the Diskeeper report view if
    you are running Norton Protect.

6.  Problems have been noted when Diskeeper is running on systems 
    that are also running Norton Internet Security Package with 
    the Anti-Virus component enabled. Enabling port 135 on the 
    affected computer corrects the problem.

7.  If you are running Diskeeper on a CITRIX server, exclude the 
    "TAB.DLL" and "DkTabProvider.DLL from the CITRIX Memory 
    Optimizer feature. If these files are not excluded, the 
    CITRIX Memory Optimizer will flag them as being "tampered", 
    when in fact they are not.


G.  INSTALLING DISKEEPER 
========================

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

Diskeeper is installed from an installation package downloaded
