About the SCSI Manager Update
-----------------------------
The SCSI Manager Update v1.0 application is PCC part number 1610-6000-00.
The SCSI Manager Update corrects a timing issue that may occur on some PowerBase computers when external SCSI devices are connected. PowerBase computers experiencing this issue will hang at the gray screen presented during the startup process and progress no further. Although the update only affects these computers, it will run on any Power Computing machine enabling customers to install the update on drives that may be used on multiple computers.
While Apple resolved this issue in Drive Setup 1.2.2, included with MacOS 7.6, a limitation of Drive Setup prevents the update from installing on non-Drive Setup formatted devices. As PowerBase systems can ship with only SCSI hard drives formatted with FWB Hard Disk Toolkit, Power Computing has developed the SCSI Manager Update for use with these drives.
The SCSI Manager Update has only been developed for use with Power Computing computers. This update will gracefully quit if run on non-Power Computing computers. Users with non-Power Computing computers based on the Alchemy architecture with no IDE hard drive installed should contact the computer"s manufacturer for assistance.
Installing the SCSI Manager Update
----------------------------------
To install the SCSI Manager Update, do the following:
1. COPY the SCSI Manager Update application to a floppy disk. The Update cannot install on to the active startup disk or the volume containing the SCSI Manager Update application.
2. RESTART the computer from the Power Computing Software CD. This can be achieved either by selecting the PowerCD as the designated startup device in the Startup Disk control panel, or by restarting the computer hold down the Command, Option, Shift, and Delete keys as the computer restarts.
3. INSERT the floppy diskette containing the SCSI Manager Update into the floppy drive.
4. After the floppy mounts, LOCATE the SCSI Manager Update icon on the floppy disk and double-click to launch the application.
5. The application will scan for all connected hard drives, inspecting them to see if they require the update. The "Select Drive" window will appear. Click on the "Next Drive" button to browse through selection of all detected drives. If a drive needs to be updated and can, the "Update" button will be enabled. You should update all drives that can be updated.
Why will the application not update my drive?
---------------------------------------------
Update only for Power Computers using FWBÕs HDT
The SCSI Manager Update is intended for use on SCSI hard drives connected to Power Computing computers using versions of the FWB Hard Disk Toolkit driver prior to version 2.0.5. FWB drivers version v1.7.5, v1.7.6, and v1.7.7 can be updated. FWB drivers version 2.0.5 and newer do not need updating. No other version of the driver can be updated.
The update will not install on hard drives formatted by a utility other than FWB Hard Disk Toolkit. In order to install the update on a non-HDT formatted drive you will need to initialize the drive and install the FWB Hard Disk Toolkit driver. Do the following:
1. BACKUP the data on your hard disk by copying the data to another drive or other suitable backup media before proceeding.
2. RESTART the computer from the Power Computing Software CD. This can be achieved either by selecting the PowerCD as the designated startup device in the Startup Disk control panel, or by restarting the computer hold down the Command, Option, Shift, and Delete keys as the computer restarts.
3. LAUNCH the FWB Hard Disk Toolkit. HDT is located in the Utilities folder on the PowerCD.
4. SELECT the drive to up updated.
5. CHOOSE the "Initialize" command from the ÒFileÓ menu.
6. You will be presented with a warning message which states, "The disk at ID x already has data on it. Initializing it will wipe out all existing data with no possibility of recovery. PRESS the "continue" button.
7. A dialog box will appear which asks you to "Choose a partitioning method". Unless you wish to partition the drive into multiple volumes, select "Maximum Macintosh" and press the "OK" button.
Drive is Full
-------------
In order for the updater to work there must be room on the drive to add the update. If your drive is full, near full or fragmented then there may not be enough contiguous room left on the drive to add the update. To make room for the update do the following:
1. BACKUP the data on your hard disk by copying the data to another drive or other suitable backup media before proceeding.
2. REMOVE any unneeded data from the drive.
2. DEFRAGMENT your drive.
Drive has multiple partitions
-----------------------------
The update will not be installed on any drive which has had additional partitions installed onto it after it left our factory. (Examples of extra partitions are DOS partitions and backup partitions.) This can be resolved by doing the following:
1. BACKUP the data on all of the partitions by copying the data to another drive or other suitable backup media before proceeding.
2. REINITIALIZING the drive (see instructions above) then repartitioning the drive.
3. INSTALL the SCSI Manager Update (see instructions above).
4. REPARTITION the drive.
Some older drives not supported
The application will not install the update onto some drives which shipped with the Power ComputingÕs NuBus based machines, the Power 100 and Power 120. However, these machines do not need the update unless you plan to move the drive to a PowerBase computer. If you do intend to move a drive from a Power 100 or Power 120 to a PowerBase, you will need to reformat the drive with a later version of HDT (1.77 or newer) or use HDT 2.0.5 and the update is not required.
What is installed by the SCSI Manager Update?
---------------------------------------------
The SCSI Manager Update updates a partition on all hard drives attached to the computer, internal and external. None of the SCSI Manager Update changes are visible after installation as the Update will not install any system software. To confirm whether or not the update is installed, run the update application again. You can confirm which devices have been updated by selecting the drive after the scanning process. The "Select Drive" window will display the status of the patch for the selected device.
The SCSI Manager Update v1.0 application is PCC part number 1610-6000-00.
