RUNNING NORTON SPEED DISK ON PROMISE STRIPE SET DRIVES
* Before running Norton Speed Disk on a stripe set of drives on a Promise controller, use the Promise UltraTune utility to set the PCI utilization to "less".  

______________________________________________________________

INSTALLING NORTON SPEED DISK
To install Norton Speed Disk:
1. Insert the Norton Speed Disk CD in the CD-ROM drive.
   If the installation window does not appear, open the CD and 
   double-click CDSTART.EXE.

2. Click Install.

3. Proceed through the installation screens.
   During installation you have a chance to confirm the location to 
   install Norton Speed Disk.
   
To install Norton Speed Disk to a different location, click Browse, 
    select another folder, or enter a new folder name, and then click OK.

4. Select a Program Group Option:
    * Group Will Be Common To All Users
       Anyone who logs into the host machine can use the new 
       Norton Speed Disk group.
    * Group Will Be A Personal Group
   NOTE: Only the person currently logged in can use the new Norton Speed Disk group.

5. Indicate if you want LiveUpdate to check for program updates after installation. If an update exists, LiveUpdate will download and install the update. You must have an Internet connection to access the Symantec LiveUpdate FTP server. For more information, see the Norton Speed Disk for Windows NT Workstation User's Guide.

6. If you wish to register Norton Speed Disk at the end of installation, please complete the screens presented by LiveAdvisor. If you wish to delay registering Norton Speed Disk you may register at a later date using the Help/About screen.

At the end of installation, Norton Speed Disk is installed to the path selected in Step 3, for example:
c:\Program Files\Norton Speed Disk\

A menu item is also added to the workstation Start menu.

______________________________________________________________
STARTING NORTON SPEED DISK

To start Norton Speed Disk:
1. Click Start, point to Programs, and then click Norton Speed Disk.
You can also double-click the Norton Speed Disk icon that was placed on the desktop during installation.
The Norton Speed Disk window appears with the Optimization Map open. (The map colors are gray until Norton Speed Disk scans a drive.)

2. In the view bar (on the left), click an icon:
* The Optimization Map view lets you optimize drives. After you start optimizing, the drive map shows the file types in the colors displayed in the Legend. 
* The Analysis view lets you generate statistics about a selected drive. 

* The Drive Options view lets you customize file placement on a drive. 

* The Schedule Options view lets you set an optimization schedule for each drive.

* The Legend lists the file types represented by the colors in the drive map. 

===============================
PREPARING FOR OPTIMIZATION
===============================
Before optimizing any drives, you should make the following preparations:

RUN CHKDSK
* Run the NT/2000 CHKDSK utility to identify and repair any disk errors before running Norton Speed Disk. Running CHKDSK also ensures that lost file sectors or chains are not included in the optimization.
On Windows NT 4.0 systems an unconditional CHKDSK of any NTFS file systems will be carried out before Norton Speed Disk runs.

DELETE TEMPORARY FILES
* Delete temporary and obsolete files such as those in the \Temp directory, any spool folders, any Internet temporary files, the Recycle Bin, and so on. This avoids the extra work of optimizing obsolete, unused, and trash files that consume optimization time and resources. Including these file in optimization means that useful space is occupied by useless files, causing the drive to become refragmented when these files are emptied from the Recycle Bin or erased from temporary folders.

INSTALL OR UNINSTALL SOFTWARE
* Complete any major software installations or uninstallations before optimizing. This reduces the necessity to reoptimize after the installation or uninstallation. Typically, installation processes create temporary files, and occupy large amounts of space temporarily. Uninstalling programs after optimizing creates unnecessary work.

BACK UP FILES
* It's always a good idea to back up your data. Although Norton Speed Disk maintains the integrity of your data, we strongly recommend that you back up important files before making any major changes to your drives, including optimization. Maintaining a schedule of regular backups is good practice at any time.


=========================================================
MISCELLANEOUS ISSUES
=========================================================

___________________________________________
UPGRADING FROM NORTON SPEED DISK 5.0 TO 5.1
* Any existing installation of Norton Speed Disk 5.0 should be uninstalled before installing this version due to changes in program options available.
In the event that version 5.1 is reinstalled to a system with an existing 5.1 installation, it should be reinstalled to the same directory as the original installation.

______________________________________________________________
NORTON UTILITIES OPTIMIZATION STATISTICS VS. NORTON SPEED DISK 
* The fragmentation reports for Norton Speed Disk display different statistics than Norton Utilities for Windows NT. This is because fragmentation is calculated in a different and improved way in Norton Speed Disk. Different algorithms are used to calculate fragmentation for Norton Speed Disk. The fragmentation level is determined by this formula: [total file fragments]/[number of files] expressed as a percentage. Unfragmented files are counted as a single fragments.
You may see this same behavior of reporting different statistics with Executive Software's Diskeeper, or the built-in defragmenter that is included with Microsoft Windows.

______________________
OPTIMIZING FAT VOLUMES
* Norton Speed Disk optimizes FAT and NTFS volumes using different methods. Please refer to the User's Guide, "Why doesn't Norton Speed Disk completely optimize my FAT volume" in the Frequently Asked Questions section.

______________________________________________
SCAN FOR ERRORS BEFORE OPTIMIZING NTFS VOLUMES
* Enabling this setting in Global Options will run CHKDSK on an NTFS volume (if currently selected) before proceeding with optimization. If the current drive is a FAT volume a prompt will appear to request that CHKDSK be run before the optimization takes place. Please note that, due to the nature of the upgrade from the version of NTFS used under Windows NT 4 to the version used by Windows 2000, NTFS volumes that have undergone this transition will not be CHKDSKed before optimization. Running CHKDSK manually before optimization is recommended.

_________________________________
PRIVILEGES REQUIRED TO RUN CHKDSK
* You must be a member of the Administrators group in order to run CHKDSK.

___________________________________
USAGE OF THE OPTIMIZATION THRESHOLD 
* Note that the option to optimize based on threshold only applies to optimizations scheduled by Norton Speed Disk. The threshold does not apply to optimizations run manually, scheduled by NSC, or run by other means.

__________________________________________
MINIMUM FREE DISK SPACE NEEDED TO OPTIMIZE 
* Norton Speed Disk needs very little free disk space to optimize. Five percent or less is enough on unoptimized drives; significantly less if the drive has been previously optimized.

__________________________________________________________
SOME FILES APPEAR IN RED WHEN OPTIMIZING ON A BUSY MACHINE 
* When a machine is very busy, transient files that are being created and deleted will appear unmovable to Norton Speed Disk. The disk areas where these files are located will be marked unmovable on the Optimization Map.

_________________________________________________________________________________________________
RUNNING NORTON SPEED DISK IMMEDIATELY AFTER INSTALL AND REBOOT ON A SLOW MACHINE SOMETIMES FAILS.
* If you run Norton Speed Disk immediately after a reboot (when one was required by install), Norton Speed Disk may fail to start. This is because the updating and registering of files hasn't completed yet. Simply wait a minute or so and try again. This will happen at most once on a machine.

___________________________________________
OPTIMIZING LARGE OR BADLY FRAGMENTED DRIVES 
* Norton Speed Disk optimizes your drive completely with one run. To do this requires planning how the entire drive will look in advance. For large complicated drives this may take more memory than you have available in your pagefile. If you receive an "out of virtual memory" message, please make your pagefile larger.

_________________________________________________________________
NORTON SPEED DISK REQUIRES 8.3 NAME SUPPORT ON THE INSTALL VOLUME
* We require that the volume we are installed to support both 8.3 and long file names.

______________________________________
MAXIMUM CONCURRENT DRIVE OPTIMIZATIONS
* If you change any Drive Options or Global Options settings, including the maximum number of drives to optimize concurrently, you must restart Norton Speed Disk before the changes take effect.

________________________________________
IF NORTON SPEED DISK REFUSES TO OPTIMIZE
* Norton Speed Disk runs a quick integrity check before beginning to optimize. If a disk error is detected, it will not run. Two conditions that will cause Norton Speed Disk not to run or not to optimize are: 
* Lost allocations on a drive.
* Free space allocated on the volume bitmap. These will display as unmovable files in the Optimization Map.

______________________________________
NORTON SPEED DISK AND NORTON UTILITIES
* If you install Norton Speed Disk to a machine that has Norton Utilities for Windows NT installed, and then launch Norton Speed Disk, the Norton Utilities version of Norton Speed Disk will appear.
You must uninstall Norton Utilities if you wish to use Norton Speed Disk to optimize your drives.

____________________________________
SCHEDULER HAS 15 MINUTE GRACE PERIOD
* Norton Speed Disk has a 15-minute grace period for scheduled events. if a machine becomes available at any time within 15 minutes of a scheduled event time, Norton Speed Disk will start the event.  

____________________________________________
NTFS DRIVES CONVERTED TO WINDOWS 2000 FORMAT
* It is not possible to chkdsk an NTFS drive in Windows NT that has been previously mounted by Windows 2000 because Windows 2000 modifies the format of the drive slightly. It is safe to optimize the drive with Norton Speed Disk. If Norton Speed Disk attempts to verify the drive, it will tell that you need to run chkdsk manually. This can only be done when booted into Windows 2000.

_______________________________________________________________________________
INSTALL INDICATES REBOOT NEEDED, BUT THEN DOES LOGS YOU OUT AND DOES NOT REBOOT
* On rare occasions, the install does not correctly reboot the machine when reboot is required. Instead the install simply logs you out. This has been seen more often on servers. The reboot is required, so please reboot the machine manually before running Norton Speed Disk. If you do not reboot, you will get error on starting Speed Disk with either ordinal 6605 cannot be found in MFC42.DLL or entry point _lc_collate_up cannot be found in msvcrt.dll.

______________________________
LARGE FILES COMPRESSED BY NTFS
* Large files, compressed by NTFS, may cause Speed Disk to take a long time to optimize a volume. Ordinary compressed files, such as .ZIP archives, are not a problem. However, 500 MB-compressed-size files (and larger), which were compressed by the file system, take a long time to piece together. To avoid Speed Disk taking a long time on these files, if space permits, uncompress the affected files.

_______________________________
AUDITTING AND NORTON SPEED DISK
* If you are using the Auditting feature, in some situations the Event Log (Security section) may be flooded with events from Norton Speed Disk while it is defragmenting your drives.

_____________________________________________
TERMINAL SERVICES AND CLUSTER SERVICES
* It is not possible to run Norton Speed Disk on an NT 4 or Windows 2000 system that has terminal services or cluster services present. These must be removed before Norton Speed Disk will operate. Merely disabling the services will not allow Norton Speed Disk to start.
