PerfectDisk version 8.0 provides new and enhanced features and easier navigation for home users, SMB (Small and Medium Business), and enterprise users. There is better performance on larger drives, improved reporting and manageability, full 64-bit support, and many more exciting new capabilities. The new version of PerfectDisk version 8.0 has two interfaces: Client and Command Center, designed for single users, small user groups, and corporate users. PerfectDisk Client is designed for home users or small business users who need to manage their computers individually. PerfectDisk Client simulates most of the functionality of PerfectDisk 7.0 with new and enhanced feature additions.

PerfectDisk Client's New and Enhanced Features :
* NEW patent-pending Resource SaverTM technology allows PerfectDisk to find all the pieces of a file without first opening the file, saving all the system resources typically required to open each file. This allows PerfectDisk to more efficiently defragment even the largest of drives with minimal system impact.

* Statistics: The following NEW features have been introduced in the Statistics:
- Addition of new graphing ability to visually track fragmentation and performance statistics over a period of time.
- Additional File Type statistics have been added. There are several pre-defined file types based on file extension (text, program, music, graphic, video) as well as users can add additional extension to these defined file types. This allows users to quickly identify what "types" of files are on their system (number of files and size on drive) and which ones are taking up the most space.
- Last Analysis or defrag bitmap statistics are available. This allows USERS to run PerfectDisk and see the result of a defrag pass that occurred (at) some time in the past when the user wasn't monitoring the result.

* AutoPilot Scheduling: The entire scheduling capabilities are now under the NEW name AutoPilot Scheduling. The following - NEW and ENHANCED features have been introduced in the Scheduling:
Scheduling has been ENHANCED to allow for more robust combinations. For example, you may schedule a defrag to run weekly on Mondays and Thursdays only.
- NEW Screen Saver scheduling for the Professional version of Windows has been introduced. This allows users to have PerfectDisk automatically defragment their drive(s) when Windows detects that their computer is "idle" (not being used by the user) and the drive hasn't been defragmented in X days (user definable). This gives an additional method to allow you more flexibility to scheduling defragmentation.

* NEW Single File Defrag: Rather than defragmenting the entire drive, this allows users to quickly and efficiently select a single file for defragmentation (e.g., graphic or video file that you may be working on, game file, etc.).

* NEW Consolidate Free Space Defrag: part of PerfectDisk's Space Restoration TechnologyTM. This method creates the largest piece of contiguous free space available which can be useful prior to creating large files or in performing partition resizing operations. It is also useful prior to compressing a virtual hard drive on a virtual machine, as a large amount of contiguous space can be recaptured.

* NEW I/O throttling: PerfectDisk automatically detects if the drive is "busy" and thus reduces its drive I/O usage during that time. This allows PerfectDisk to run on very busy drives without imposing any additional load.

* NEW CPU throttling: PerfectDisk allows you to raise or lower the CPU priority at which it runs. While PerfectDisk actually uses very little in CPU resources, it allows customers that have CPU bound systems to feel comfortable running PerfectDisk at a lower priority and not impose a noticeable CPU load on the system.

* NEW Automatic shutdown after defrag: PerfectDisk has the ability to automatically shut down the system after a defrag pass has been performed (Workstation versions of Windows only).

* NEW Power Management: PerfectDisk detects if a system is running on battery (UPS) and then decides whether to stop or not start defragmentation. This is most applicable to laptop users who need to preserve battery life. This is also useful for systems running on a UPS.

* NEW On Screen Help: PerfectDisk has introduced the On Screen Help functionality that gives you an overview of the actions that can be performed when a particular section of PerfectDisk is in focus. The help window is located at the right side of the PerfectDisk window and can be resized or closed.

PerfectDisk Command Center:
For corporate users, the new PerfectDisk Command Center, a management console for deploying, scheduling, configuring, managing, and reporting on your enterprise defragmentation. The PerfectDisk Command Center is designed for the corporate user who manages a group of computers in large scale corporations. PerfectDisk Command Center provides the ability to deploy, manage and configure multiple computers on networks without users needing to know how to use Active Directory or 3rd party tools.
* The goal of the Command Center is to provide the ability to manage a group of computers remotely and simultaneously. The PerfectDisk Command Center provides a single glance status summary showing any fragmentation "issues" found with your managed computers. "Issues" could be that a defrag pass has never been performed, a scheduled defragmentation pass didn't run as configured, file fragmentation is high, free space fragmentation is high, etc...
* Alerts are color identified to visually draw attention to any problems that administrators can then quickly resolve.
* Administrators can deploy and update PerfectDisk quickly and efficiently across a large number of systems. Administrators can check the status of deployment and updates at any time.
* Provides the ability to custom define groups and only see those computers that you want to manage. If you only manage 10 computers, you don't want to see 100 computers in your network.
* Provides email notification if an Alert or Warning threshold is reached. Administrators do not have to remember to check if there are issues. PerfectDisk notifies them automatically if there are any issues. This removes the checking from their daily/weekly checklist of things to do.
* For each managed computer, a connection directly to terminal service/remote desktop is provided. If there is an issue, the administrator can directly remote into that computer without having to leave the PerfectDisk Command Center. This saves time in troubleshooting.
* PerfectDisk Client statistics are accessible from the PerfectDisk Command Center, allowing administrators access to the data for reporting purposes.

Changes in PerfectDisk 8.00.63:
• PerfectDisk Command Center
1. If you ran the Fragmentation report, the Alert report and the Fragmentation report again, some columns disappeared. This has been fixed.
2. When Saving or Printing the Alert report, an extra column was added. This is was a hidden column used for initial sorting. This has been fixed.
3. In the Managed Computers dialog, Vista machines were not displayed. This has been fixed.
4. When using the Configure Client Settings Wizard, you could set the Proxy settings associated with the AutoUpdate settings, however you could not clear them. This has been fixed.
5. On the Machine View tab, the Next Scheduled Run date was not always populated. This can occur if you have a one time schedule which has already been executed. This has been fixed.
• PerfectDisk Client
1. When performing a boot-time defrag pass on Vista with the pagefile on a non-system drive, you received an Access Denied message. This was due to the IO manager opening and closing a handle to the pagefile. NTFS does not monitor for closing of the pagefile. We have worked around this issue.
2. When performing a boot-time defrag pass on a volume which was shrunken using the Drive Manager on Vista, PerfectDisk failed with a buffer overflow error. This was because when the drive was shrunken, the $Bitmap file was not reduced to match the drive size. We have worked around this issue.
3. Single file defrag was not supported on unmounted drives. This has been fixed.
4. There was a display issue when manually defragmenting an Exchange data store. This has been corrected.
5. When un-installing PerfectDisk you sometimes received the following error in the event log:
"SELECT * FROM PDEvent" whose target class "PDEvent" does not exist".
This has been fixed.
6. When using Find File the color displayed for the selected file sometimes changed. There was a bug which caused this if the first block being displayed contained files of different categories. This has been fixed.
7. Changes were made to the Screen Saver schedule to stop quicker on Win2000 and XP, and to run on Vista.
8. Localization support was added for German and Japanese.
9. Unmovable files were sometimes listed twice in the statistics. This has been fixed.
10. The UI could sometimes exit on a race condition when defragmenting multiple Exchange data stores. This only affected the display and not the actual defrag pass. This has been corrected.
11. If a boot-time defrag pass was set for next reboot, and an online defrag pass was executed on the same drive, the offline pass was cancelled. This has been fixed.
12. Fixed a display issue with PerfectDisk logs. If your time zone was GMT+ then log display was incorrect and delayed. You would observe the log file as being empty until some period of time passed and them the logs would populate. This has been fixed.
13. Additional code was added to allow PerfectDisk for Exchange to log more information to the application event log.

Changes in PerfectDisk 8.00.64:
āˆ¢ PerfectDisk Command Center
1. When viewing the History dialog, the text display was sometimes poorly formatted. This has been fixed.
2. Console incorrectly displayed the Last Run Date for a computer added to an existing schedule. This has been fixed.
3. Code was added to support adding computers to a group using the fully qualified domain name (ComputerName.Domain.com).

āˆ¢ PerfectDisk Client
1. Code was added to exclude certain SafeBoot encryption files. Moving these files could cause your computer to become non-bootable.
2. If your drive was very large PerfectDisk displayed some of the statistics using scientific notation. This has been fixed.
