A.  PLATFORMS AND OPERATING SYSTEM VERSIONS SUPPORTED
=====================================================

Diskeeper is supported on Intel x86 (or compatible) platforms 
running Windows 95, Windows 98, Windows ME, Windows NT 4.0, 
Windows 2000, Windows XP, and Windows Server 2003.

Note that different editions of Diskeeper support different
ranges of the Windows operating systems. See the Table of 
Supported Operating Systems for a chart of the different 
Diskeeper editions and the Windows versions each supports.

Also note that Diskeeper requires Service Pack 6 or higher 
on Windows NT systems, and OSR 2 or higher on Windows 95 
systems. 


B.  OVERVIEW OF DISKEEPER 9.0
=============================

Diskeeper 9.0 represents another step forward in 
defragmentation technology, with refinements to existing 
features and the addition of new options that are the 
result of Executive Software’s ongoing technical and 
market research.

As in earlier versions, Diskeeper 9.0 is designed to 
solve fragmentation problems for everyone, from home users 
to huge enterprise IT departments.

This document describes the operation of these Diskeeper 
editions:

o  Diskeeper Professional Edition
o  Diskeeper Server Standard Edition
o  Diskeeper Server Enterprise Edition

In addition to these versions, the Diskeeper family of products 
also includes Diskeeper Home Edition for home users and Diskeeper 
Administrator Edition, an administrative console for controlling 
Diskeeper installations throughout your network. 

Diskeeper Home Edition incorporates simplified controls, and does 
not support the network defragmentation capabilities available in 
the other Diskeeper editions. Diskeeper Administrator Edition is 
not a defragmenter, but an application that provides a single point 
of control by which you can control all the Diskeeper 9.0 
installations on your network. 

See the Table of Supported Operating Systems at the end of this 
Readme file for a chart of the different Diskeeper editions and 
the Windows versions each supports. 

The following list summarizes the most important Diskeeper 
features:

o  Wide Array of Diskeeper Editions-
   The Diskeeper family of products offers specialized 
   defragmentation of Windows operating systems ranging from 
   Windows 95 through Windows Server 2003 Datacenter Edition.

o  Descriptive Interface-
   The Diskeeper interface provides an intuitive and informative 
   defragmentation experience. Common commands are grouped 
   together in the Command 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. 

   New in version 9.0 is the Performance Map tab. This tab shows
   a graphic representation of your disk similar to the Drive Map,
   with one major difference: It shows the extent of performance 
   degradation on the disk instead of simply showing the 
   fragmented files. 

   For example, a large file in two or three fragments causes no 
   significant performance loss. In this case, the Drive Map tab 
   would display this file in red (since it is framented) but the 
   Performance Map would display the same file in blue (since it 
   is NOT affecting the performance of your computer). The 
   Performance Map tab gives you a more accurate look at the 
   condition of the disk as it relates to the overall 
   performance of your system.

o  Performance and Reliability Analysis-
   Diskeeper collects and displays data regarding the performance 
   and reliability of your disk volumes. This information allows 
   you to be more proactive in the management and maintenance of 
   your computers. 

   It should be noted that the first performance analysis is based 
   on pre-determined disk performance values measured as a part of 
   disk performance research done by Executive Software. To get a 
   more accurate performance measurement of your actual disks, 
   Diskeeper must scan your drives to measure their performance. 
   Since this measurement can briefly slow down your computer, 
   this scan operation is disabled by default, but you can turn 
   it on easily. The "Set performance data options" option is 
   described in the Diskeeper help system.

o  Set It and Forget It Operation-
   Diskeeper is designed to operate without your intervention. 
   Set a schedule for the times you want Diskeeper to run, then 
   sit back and let Diskeeper take care of your disk fragmentation. 
   Of course, you can also run Diskeeper manually.

o  Smart Scheduling-
   This feature allows Diskeeper to automatically determine the 
   optimum defragmentation schedule for each disk volume 
   individually, and adjust that schedule as disk usage changes.

o  Secondary Schedules—
   Diskeeper supports two separate defragmentation schedules for 
   each of your disk volumes. This allows you to set one schedule 
   for weekdays, and another for weekends. Or you can run 
   low-priority defragmentation jobs during the day when the 
   computer is active, and another, higher-priority job in 
   the off-hours.

o  Selectable Run Priority-
   You can select the Windows priority at which Diskeeper 
   defragmentation jobs run. Set the priority independently for 
   both "Set It and Forget It" and "Manual Defragmentation" jobs.

o  Frag Shield[TM]—
   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. Special measures must be taken 
   to defragment these files, so it is better to prevent their 
   fragmentation in the first place. The Frag Shield feature 
   helps you configure these critical system files optimally, 
   to help keep them contiguous from the start.

o  I/O Smart[TM]—
   This option takes the concept of run priorities one step 
   farther by “throttling” (suspending) the defragmentation 
   process whenever disk I/O activity is detected on a disk 
   while it is being defragmented. This ensures the 
   defragmentation process will be transparent to users, 
   no matter how active the disk.

o  Selectable Defragmentation Methods-
   Diskeeper 9.0 gives you the choice of four different 
   defragmentation methods -- each with benefits for specific
   circumstances. 

   New in version 9.0 is the "Performance Defragmentation" method.
   This algorithm concentrates the defragmentation effort on the 
   pieces of fragmented files that affect your disk performance 
   the most. This method moves and defragments smaller file 
   fragments, but does not attempt to move large file fragments, 
   thus saving time and system resources. 

   Large file fragments in two or three pieces have very little 
   (if any) performance impact, but attempting to consolidate these 
   large pieces into a single, contiguous piece can consume more  
   resources than accessing the slightly-fragmented (or partially 
   defragmented) file.

o  More Control for Non-Privileged Users-
   The Diskeeper icon in the system status area (also known 
   as the system tray) can now be used by non-administrative 
   users to postpone defragmentation operations. Users who 
   are not members of the Administrators group can right-click 
   the Diskeeper system tray icon to delay a currently-running 
   defragmentation operation. 

   Users who are members of the Administrators group can now use 
   the Diskeeper icon in the system tray to open the Diskeeper 
   interface and have full control over Diskeeper operations.     

o  Group Policy Support—
   Diskeeper can be configured network-wide with the Group 
   Policy Editor provided with Windows 2000 Server and Windows 
   Server 2003.

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

o  Event Logging-
   Diskeeper allows you to record information about its activity 
   in a log file. A wide variety of information can be saved for 
   future reference.

o  Simultaneous Analysis or Defragmentation Operations-
   You can analyze and/or defragment more than one disk volume at 
   a time. Different Diskeeper editions support different numbers 
   of simultaneous operations. See the Table of Diskeeper 
   Editions in the Diskeeper Help for  more information.

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

o  Terabyte Volume Engine-
   A Diskeeper exclusive, the Terabyte Volume Engine (TVE) is 
   designed to efficiently defragment extremely large disk 
   (>100 GB) volumes. This feature is available in selected 
   Diskeeper Server editions. See the Table of Diskeeper 
   Editions in the Diskeeper Help for a list of the Diskeeper 
   editions with TVE support.

o  Support for Mounted Volumes-
   Diskeeper now supports mounted volumes (or letterless drives),
   which can be created on Windows 2000 and later operating 
   systems.
   
o  64-bit Processor Support-
   Diskeeper is compatible with 64-bit versions of Windows 
   Server 2003.


C.  KNOWN RESTRICTIONS IN THIS RELEASE
======================================

1.  The Windows NT 4.0 version of Diskeeper will not defragment
    NTFS volumes formatted under Windows 2000, or that were 
    upgraded to NTFS 5 volumes. The Windows 2000 version of 
    Diskeeper will defragment these volumes. If you have a 
    dual-boot system with Windows NT and Windows 2000, you must
    defragment all your disk volumes from the Windows 2000 boot.

2.  Diskeeper needs access to the root directory on a volume to
    display the volume in the GUI. Diskeeper runs under the 
    SYSTEM logon, so if an NTFS volume is not appearing in the 
    volume list, make sure that SYSTEM has FULL CONTROL on the 
    root directory of the volume.
 
3.  Diskeeper needs to be able to access a file to defragment it.
	
    a) If a file on an NTFS volume does not grant FULL CONTROL to
       the SYSTEM logon, Diskeeper will not be able to defragment 
       it.
 
    b) If a file on an NTFS volume is open for update with an 
       exclusive lock, Diskeeper will not be able to defragment
       it. You will need to shut down the application that has
       a file open in this mode in order to defragment it.

4.  Under Windows NT 4, Diskeeper will not defragment FAT-32 
    volumes, as FAT-32 was not a file system supported by
    Microsoft under Windows NT 4. Diskeeper will, however 
    defragment FAT-32 volumes when running on Windows 98, 
    Windows 2000 and Windows XP systems.

5.  Boot-Time operations on very large or very fragmented volumes
    may take longer to complete than expected. We therefore 
    recommend you do a thorough online defragmentation of a volume
    before you perform a Boot-Time Defragmentation on it. We also
    recommend doing the Boot-Time Defragmentation on only one 
    volume at a time.

6.  When running the Diskeeper boot-time operations, you can use 
    the ESC key to terminate the operation. Note that this option 
    is only available if your hardware supports it. If pressing the 
    ESC key does not stop your boot-time engine, you can safely 
    restart your computer by pressing its reset button. In that case, 
    you should run CHKDSK after restarting the system, to free up 
    any unused clusters that may not yet have been released due to 
    the abrupt shutdown.

7.  If User Profiles are enabled on Windows 95/98/Me systems,
    Diskeeper will only be available under the logon of the user
    who installed it. If you are using multiple user profiles,
    you can install Diskeeper from within each profile to make it
    available to that profile.

8.  Although Diskeeper attempts to lock removable drives, some 
    may not be lockable, or may eject anyway if the eject button 
    is used. Data corruption may occur if you eject a removable
    disk while defragmentation is occurring on that disk.

9.  When multiple disk volumes are scheduled to be defragmented
    with the same starting time, defragmentation is started on
    the volumes one at a time, with one-minute intervals between
    each starting time. This is by design.

10. If you are running Internet Explorer 4.0 and using Dial Up 
    Networking (DUN) with a modem, starting Diskeeper can cause 
    the DUN dialog box to be displayed. To work around this, 
    disable connecting through a modem or install Internet 
    Explorer 5.0. Internet Explorer 5.0 may show similar results
    if the "Always dial my default connection" option is set via 
    the Tools | Internet options | Connection tab set.

11. If you install other software that also loads the MMC, be 
    aware that the other product may install an older version of 
    the MMC. If this occurs, Diskeeper may not operate correctly,
    and should be reinstalled.

12. FAT volumes larger than 2GB formatted on Windows NT cannot be
    defragmented under Windows 95/98/Me. This is due to a 2GB FAT 
    volume limit on Windows 95/98/Me systems.

13. 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.

14. When the post-defragmentation summary report is displayed,
    scheduled "Set It and Forget It" defragmentation jobs are
    prevented from starting. Close the summary report to allow
    the scheduled defragmentation to occur.

15. Diskeeper cannot defragment NTFS volumes with a cluster size 
    larger than 4KB in size on Windows NT 4 and Windows 2000. 
    This applies to both online and Boot-Time modes. 

    Under Windows XP and Windows Server 2003, the online and 
    boot-time NTFS defragmentation engines support cluster sizes 
    up to and including 64 Kbytes.

16. On Windows NT and Windows 95, if you do not have Internet 
    Explorer 3.0 or higher installed, you will not be able to 
    access the Diskeeper Help system interactively from Diskeeper.
    However, you can still run the Diskeeper Help by double-
    clicking the Diskeeper.chm file in the directory folder where 
    Diskeeper was installed.

17. In rare cases, the Diskeeper installation will not be able 
    to uninstall a previous version of the Diskeeper service. 
    The error displayed is "Error stopping the Diskeeper 
    Service."  If you receive this error, use Control Panel, 
    Add/Remove Programs to uninstall the previous version of 
    Diskeeper. This will enable you to resume the installation. 

18. On Windows 95/98/Me, pressing CTRL+ALT+DEL while the
    Diskeeper engine is running on the system drive, can cause 
    a "system busy" blue screen. Pressing any key should return
    you to Windows. If CTRL+ALT+DEL is pressed twice, while any
    disk volume is being defragmented, this can prevent old file
    fragments that were moved from being freed up. To avoid this
    problem, press the space bar after the first CTRL+ALT+DEL to
    return to Windows, then stop any defragmentation before 
    shutting down your computer.

19. The Boot-Time defragmentation log file path name should not 
    contain any embedded spaces. Instead, use the DOS 8.3 file 
    naming convention to specify the log file path name.

20. The Diskeeper Remote Installation feature only supports the 
    network type WNNC_NET_LANMAN, which is the standard Microsoft
    Windows Network type.

21. Windows XP Professional is by default set to "Use simple file
    sharing," which does not allow sharing of important system
    or program folders of the volume shared. To do a Diskeeper 
    Remote Installation to a Windows XP machine, from Windows 
    Explorer select Tools|Folder Options, then select the View 
    tab, scroll down in the Advanced settings window and clear 
    the "Use simple file sharing" checkbox.

22. Diskeeper can operate as a single instance application in
    all terminal server environments, in the XP Fast User 
    Switching environment, and as a cluster administrator 
    application. In addition, Diskeeper can be started with
    the "run as" command.

23. The Status Bar at the bottom of the Diskeeper display does 
    not appear on systems running versions of Internet Explorer 
    lower than 5.0. Although this is due to limitations in the 
    Microsoft Management Console (MMC), we are investigating a 
    solution.

24. When configuring the MFT on Windows NT 4.0 systems, the 
    progress display in the Frag Shield dialog box does not 
    change until the operation has completed. This only occurs 
    on Windows NT 4.0 systems.


D.  KNOWN INCOMPATIBILITIES
===========================

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

2.  We have noted occasional problems in defragmenting volumes 
    that have been configured or resized with Partition Magic. 
    If you are having problems defragmenting a volume, and it 
    has previously been configured or resized with Partition 
    Magic, it may be necessary to backup, reformat, and restore 
    the volume prior to running Diskeeper.

3.  When using an IOMEGA JAZ drive with the IOMEGA Quick.exe 
    application installed, you may receive the following blue 
    screen error message when you log on to the computer using 
    an administrative account: 

       Stop 0x0000000A (parameter,parameter,parameter,parameter)
       IRQL_NOT_LESS_OR_EQUAL. 

    The IOMEGA Quick.exe application is installed in the Startup 
    group to start automatically. It sends invalid system calls 
    that are only allowed when logged on as an administrator. 
    When the Diskeeper Boot-Time operation is run, the Quick.exe 
    application is delayed in starting, thus causing the above 
    problem.

4.  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 at End" option in the Diskeeper 
    Boot-Time option has been selected.

5.  On Windows XP systems, manual defragmentation of large files 
    (4 GB or larger) at the default priority may result in the 
    system responding poorly. This is a situation with the 
    operating system, not Diskeeper. If you find Diskeeper 
    frequently defragmenting large files and your system bogs 
    down, we recommend either adding these files to the exclusion
    list, or defragmenting them during "off hours" when there is 
    less interaction with the system. This situation has not been
    seen with Windows 2000 or Windows NT 4 systems. We are 
    working with Microsoft to resolve this situation.

6.  The keyboard functions in the Boot-time defragmenter 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 Executive 
    Software Technical Support (tech_support@executive.com). 
    Providing this information may help us narrow down why certain
    combinations of hardware and software cannot access the 
    keyboard functions in the boot-time defragmenters.

7.  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.

8.  The Terabyte Volume Engine (TVE) in Diskeeper Server Enterprise 
    Edition is not compatible with Trend Micro's HouseCall 
    free virus checking service. When the TVE is running (i.e., 
    when defragmenting volumes 100 GB in size or more) the 
    defragmentation process may stop before completion if HouseCall 
    is also running.


E.  INSTALLING DISKEEPER 
========================

Note: On Windows NT, Windows 2000, Windows XP, or Windows Server 
2003, 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.


F.  SETTING ACCESS CONTROL ON WINDOWS 95/98/Me SYSTEMS
======================================================

In some cases, the Diskeeper setup program will inform you
that it is necessary for you to change the access control 
settings on Windows 95/98 systems. If such a message is 
displayed during the installation, follow these steps to
set the access control:

1.  From the Windows Control Panel, double-click "Network".

2.  Click the Access Control tab.

3.  Enable "User-level access control".

4.  Specify the correct domain, if necessary.


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

To uninstall Diskeeper on Windows NT, Windows 2000, Windows XP, 
and Windows Server 2003 systems, you must be logged into an 
account that is a member of the Administrators group. 

Note that the controls may have slightly different names, 
depending on your version of Windows. 

Follow these steps to completely remove 
and uninstall Diskeeper from your computer:

1.  From Control Panel, double click "Add/Remove Programs". (On 
    Windows 95/98/Me/NT systems, click the Install/Uninstall 
    tab.)

2.  Highlight the Diskeeper entry.

3.  Click Remove or Add/Remove (Windows 95/98/Me/NT). This removes 
    the Diskeeper program files from your computer. In most cases, 
    the Diskeeper installation directory will not be removed.

4.  On Windows 2000, Windows XP, or Windows Server 2003 systems, 
    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.
