This file contains instructions for updating DataFrames formatted with previous versions of the Manager software, and describes the operating requirements and known general and specific compatibility information. This file assumes some familiarity with the features of Manager as described in the "Using Manager 4.1E" file and in the DataFrame Users Manual.
You can print out this file if you have a printer attached to your Macintosh and selected in the Chooser. Select Print under the File menu.
SYSTEM REQUIREMENTS
====================
DataFrame models:
All
Macintosh models:
Any Macintosh with a built-in SCSI port
Apple System Software:
System 4.1/Finder 5.5 or later
(System Tools 6.0.2 or later recommended)
(While DataFrames run properly under A/UX, the Manager program must be run under the standard Macintosh System).
Network Software:
AppleShare
TOPS
All the functions of Manager 4.1E except locking are compatible with AppleShare 2.0.1 and TOPS 2.1. This enables you to create Drawers that have passwords or are encrypted with DES and have them work as server volumes. The passwords will be requested before any server volume can be booted on the Server Macintosh. AppleShare & TOPS do not permit server volumes to be locked - but should be write-protected using access privileges. In the case of a DES server volume, data written to and read from the volume is automatically encrypted/decrypted at the server.
IMPORTANT: Do NOT initialize your DataFrame with any software other than the DataFrame Manager program from SuperMac. DataFrame performance is already optimized, and doing so could cause your locked utility software to no longer recognize the DataFrame.
Although we have tried to make sure that our drives are compatible with as many other 3rd party products as possible, SuperMac cannot guarantee complete compatibility. Our DataFrame driver conforms to Apple's standards, and we should be compatible with other manufacturers who have also followed Apple's guidelines.
This note applies to DataFrame owners currently using Manager version 4.0.4 or earlier. Skip down to "Manager Hints" if this does not apply to you. Note that "Manager 4.x" refers to all Manager versions 4.0 and later.
Every DataFrame has a small amount of basic operating software known as the "Driver." You can see what Driver version your DataFrame uses by clicking on its icon in the Manager main window and selecting Get Info from the File menu. DataFrames initialized with Manager version 3.26 will show "Version 3.2" in the Get Info window, while "Version 4.1" (no 'E') indicates a DataFrame running the current software. We recommend that you update all DataFrames that you own to the latest version of the driver.
Users of SuperMac tape drives must replace the DataStream driver 2.02 with TapeDriver 3.0 before upgrading to Manager 4.x.
If you own a 512Ke with an older Dataframe and wish to use Systems 3.2 or 3.3, you should NOT update to the new version of Manager as compatibility cannot be guaranteed. Continue using Manager 3.26 (with the 3.2 driver) for your DataFrame.
Manager makes it easy to update the driver to version 4.1. Use one of the following two procedures.
• For DF30, XP30, XP60, XP60+40, XP60+B, XP105, and XP150 or any DataFrame running driver version 4.0 or later:
1. Boot your Mac from a floppy or another drive containing Manager 4.1E.
2. Launch Manager 4.1E.
3. Click on the DataFrame's icon in the Manager window.
4. Click on Update. Manager will write a new Driver to the DataFrame.
5. Quit Manager and reboot from your DataFrame.
Note: Updating a DataFrame to Manager and Driver version 4.x allows you to password-protect the entire DataFrame and to change the SCSI ID while the disk is in use. If you want to create multiple Drawers, you will have to reinitialize and specify "Drawers" after formatting. Although it is not necessary to reinitialize to begin using the 4.x Driver version, reinitializing will insure that the entire media surface is free of defects. If you are sure your data is safely backed up, you will get the best performance by reinitializing.
• For DF20, XP20, XP40, and XP40+40 with driver version 3.2 or earlier:
In order to use these drives with the new features of Manager 4.x, they will have to be reformatted.
1. Back up your drive with DiskFit.
2. Boot your Mac from a diskette containing Manager 4.1E.
3. Launch Manager.
4. Click on the DataFrame's icon in the Manager window.
5. Click on Initialize. After formatting is complete, you may choose to create Drawers or one large Standard disk. The directories will be created for Drawers or the Standard disk.
6. Quit to the Finder.
7. Restore your data with DiskFit.
A new icon for your DataFrame will appear after rebooting with the updated Driver.
Note: If you create Drawers and the size of the largest Drawer is not large enough to hold the original contents of your disk, you will have to restore the information in your DiskFit backup set manually using the Finder.
CHANGES FROM MANAGER 4.0.4E TO MANAGER 4.1E
============================================
There have been several important changes to Manager 4.1E. Use Manager to Update any DataFrames you currently own to version 4.1 as explained above. The following fixes have been made in Manager 4.1E:
Older DataFrame 20-60MB models using separate OMTI controller boards (with vents on top) have a more stringent initialize routine that will map out marginal sectors that Manager 4.0.x may not catch. Users of these DataFrames are strongly encouraged to Test or, better, backup and Initialize their drive to be sure all marginal sectors are mapped out.
System 6.0.5 has a problem with memory space that may cause a Finder damaged message when running from a DataFrame with driver 4.0.x. Manager 4.1E includes a workaround that prevents this problem.
Manager 4.0.x would damage A/UX partition information when the Drawers box was accessed. This does not occur with Manager 4.1.
The password dialog at startup is now 32-bit clean.
The LaserFrame optical drive and hardware SCSI ID selection on some DataFrame models are now supported.
MANAGER HINTS
==============
Below is a list of release notes that will help to make your use of the new Manager as trouble-free as possible.
Before starting your Mac, make sure that you have allowed enough time for your drive to spin up completely. Thirty (30) seconds should be long enough to ensure that the drive is ready. If the drive is not ready, it may not start up properly.
If your password is not working, the first thing to do is check the Caps Lock key. If you forget the password of a Drawer, you will not be able to access or remove it. SuperMac will not be able to recover your data, and cannot assume responsibility for lost passwords. In this case, the only way to get a clean start is to reinitialize.
All current model DataFrames automatically park their read/write heads when they are turned off. To park the older 20, 30 and 40 megabyte DataFrames, hold down the Option key when selecting Shut Down from the Special menu in the Finder. The Park command in Manager can also be used to park the heads of older DataFrames.
Many DataFrame drives change ID automatically through software. Unlike previous versions of Manager, Manager 4.x now allows SCSI IDs to be changed even when a drive is in use. Please note that for some mechanisms (current DataFrame 20, XP30 and XP60 models), the new ID does not take effect until the DataFrame has been turned off and then back on again. Manager informs you of this in the change ID window where necessary.
When the test is run and defects are detected, Manager will map out the bad areas (sectors) it detects and also attempt to move any data that may be stored in the bad sector. There is no way of knowing what file is on a bad sector of the drive, and Manager will move any data that can be successfully read.
When using the Startup Device cdev with multiple Drawers, please note that it only saves the SCSI ID of the entire DataFrame. If you close the cdev and reopen it, you will note that all the Drawers on the drive you selected are highlighted - this is normal since the SCSI ID is being saved, not the specific Drawer. To designate a specific Drawer to be the Startup Drawer, use the Startup Drawer feature under the Drawers menu in Manager.
If the name of a Drawer protected by a password or DES is changed, the name change will not be immediately reflected in the password dialog. In order to completely change the name, run Manager and open the Drawers dialog with the Drawer mounted. The Macintosh's volume information and the partition list entry will then be made to match. This anomaly also occurs with unprotected Drawers but is less obvious due to the fact that no password is requested. [This note is of special relevance to DiskFit and Network DiskFit: in the uncommon event that Drawers are being used as SmartSet disks, the name changes that DiskFit makes (i.e. 1.SmartSet, 2.SmartSet...) will not take effect until the Drawers dialog is opened in Manager.]
The Manager CDEV cannot unmount volumes in the Finder. Volumes can always be unmounted by dragging them to the trash. The Manager CDEV will not see drives when there is no driver loaded (e.g. if you boot to the Desktop and then turn on the drive). In this case, Manager should be used to Start the drive.
If "Open Automatically" is deliberately turned off on a DataFrame that has been formatted as Standard, it will not boot. The only way to mount it is with Manager or the CDEV.
When creating Drawers, bear in mind that the Finder has memory limitations and may run into problems if you are trying to have too many volumes mounted at one time. Having 5 or fewer Drawers mounted simultaneously should not cause memory problems to occur. The "Max Number of Open Files" parameter in the boot blocks defaults to 10; this represents the total of both mounted volumes and open files at one time. Power users may increase this value (no higher than 25!) using FEdit or similar utility if it is desired to have more open volumes. If you are running under MultiFinder and have the memory to spare, you can allocate more memory to the Finder (160K is the default setting).
Drawers smaller than 400K will be created as MFS volumes. If, for some reason, you require an HFS volume smaller than 400K, you can select a Drawer and use the "Erase Disk" command in the Finder while holding down the option key. This will not work on Drawers that are 100K or smaller.
When opening or saving a file, Drawers can appear in the Open or Save dialog boxes two different ways - with a floppy or hard disk icon. The cut-off point is 2083K. If a Drawer is created in Manager that is 2084K or bigger, it will have a hard disk icon in Open or Save dialog boxes.
When using a grayscale monitor, be sure that you have set the Monitors cdev to grayscale mode. This will cause the partition wheel to use patterns to represent the various Drawers instead of shades of gray. If your grayscale monitor is set to color mode, the partitions on the wheel may be very hard to distinguish.
COMPATIBILITY WITH SPECIFIC PRODUCTS
=====================================
Apple File Exchange will not work unless all Drawers are mounted. This is a bug in AFE.
The SCSI Tools cdev and the MountEm™ FKEY will not be able to mount DataFrames that use the 4.x driver. DataFrames require a more sophisticated mounting procedure due to the various protection methods. If you need to mount drives or Drawers, use Manager or the Manager CDEV. (SCSI Tools version 1.0 will cause some SuperMac and Apple drives to hang just by opening it.)
Older ROM versions for the Radius Two Page Display for the Macintosh SE exhibit an anomaly with password dialogs where the characters for the password appear a few inches to the right of the password dialog. This is due to the fact that the Radius board makes patches to QuickDraw that cause centering to occur differently on the Two Page Display Screen. All the keys work correctly and the password is recognized when entered.
Prodigy 4 Mac Plus users note: You must use emulation mode to change ID and to reinitialize the DataFrame. This is due to Prodigy 4 patches to the SCSI Manager code.
