Additional features/notes of HDT not mentioned in the manual:
General
-------
Serial numbers are of the format ZZXXXXXXZXZ, where X are numbers and Z are letters. If you are upgrading from an older version of HDT, please use your old serial number. Older JackHammer serial numbers are of the format JXXXXXZXZ, where J is the letter 'J', X are numbers and Z are letters. Do not enter any spaces or confuse zeros with the letter O. The disk from which you run the program must also be write-enabled before personalization can occur. You can run the program off a write-protected disk without saving the personalization information. Do not use the original master disks to personalize the program, make a working backup copy.
Update Information
-----------------
All users of older versions of HDT should replace all modules with the latest versions. Make sure you delete old versions of files from your Control Panels and Extensions folders, as they will not be automatically deleted. You should also perform an Update Driver from within HDT Primer on all drives and cartridges.
Starting up a Centris, Powerbook, or Quadra computer that has only one hard drive
You will not be able to reinitialize the boot or start up hard disk; you will need to start up your computer with a different disk, such as a RAM Disk. Perform the following steps to create a RAM Disk:
1) Start up the computer with System 7, 7.0.1, 7.1, or newer (as required by your CPU). Make sure that this System Folder contains the Memory and Startup Disk Control Panels.
2) Use the Memory Control Panel to create a RAM disk of at least 1536K in size (or the size of your current System folder). Make sure you leave at least 3000K of free RAM for the computer to startup and for HDT Primer to load.
3) Restart the computer to initialize the RAM disk and make it mount on the Desktop.
4) Insert the Apple System Software Disk Tools floppy disk (or Emergency Startup Floppy disk that you have created for your computer) into your floppy disk drive and copy the System Folder (or copy your hard drive's System folder) to the RAM Disk.
5) Use the Startup Disk Control Panel to select the RAM Disk as the Startup Device.
6) Restart the computer to start off of the RAM Disk.
7) Insert a copy of the HDT Disk 1 and launch the HDT Primer application.
You are now ready to manipulate your hard disk drive. (You could also copy HDT Primer and Drive Data to the RAM Disk.)
Building a System 6 Startup Disk
-------------------------------
Please perform this BEFORE a situation arises where a bootable floppy is needed.
1) Start up your computer and initialize a fresh double density or high density floppy disk.
2) Copy the 'System' file from the System 6.0.7 or 6.0.8 System Tools onto this disk.
3) Copy 'HDT Primer' and 'Drive Data' onto this floppy.
4) Rename 'HDT Primer' to 'Finder'.
You have just created an emergency startup disk that will automatically launch HDT Primer when you start up off this disk.
Building a System 7 Startup Disk
------------------------------
Please perform this BEFORE a situation arises where a bootable floppy is needed.
1) Start up your computer and initialize a fresh high density disk. Unmount the disk by dragging it to the Trash.
2) Restart your computer and start up off the Macintosh System Software Installer disk that came with your computer. (Installer or Install Me First disk)
3) Select the Custom button. Select 'Minimum System' for your particular computer from the list of choices.
4) Click on Switch Disk button until the name of the Installer floppy comes up and hit the 'Eject' button. Insert the floppy created in step 1.
5) Click on the Install button and insert the correct floppy when prompted. Quit the Installer and restart the computer and start up off the Disk Tools disk.
6) When at the Desktop, select the Disk Tools floppy icon and select 'Eject' from the Special menu. Insert the newly created minimum system start up floppy.
7) Open the System folder on your floppy. Drag the file entitled 'System' and any Enabler file out of the System folder onto the main window of your floppy. Drag the System Folder into the Trash and empty the Trash. During this process you will be prompted to swap floppy disks several times.
8 Eject the floppy and insert HDT Disk 1. Copy 'HDT Primer' and 'Drive Data' from HDT Disk 1 onto this floppy.
9) Rename the copy of 'HDT Primer' to 'Finder' on the floppy.
You have just created an emergency startup disk that will automatically launch HDT Primer when you start up off this disk.
SCSI Manager 4.3
---------------
Hard Disk ToolKit is fully compatible with Apple's SCSI Manager 4.3. Updating or installing the latest FWB drivers will allow you to exploit the capabilities of Apple's SCSI Manager on Apple's AV, PowerMacintosh, and PowerPC Upgraded Macintosh computers. The benefits of FWB's latest driver coupled with Apple's SCSI Manager 4.3 are: reduced SCSI I/O processing overhead, asynchronous SCSI I/O, and maximized SCSI bus utilization which translates to higher overall data throughput.
HDT BenchTest™
---------------
1) The entries in the saved results library from FWB are not deletable.
2) 65,535K (64MB) is the largest transfer size that can be manually entered in user mode.
HDT Extension™
--------------
1) The extension normally displays icons with numbers showing which SCSI IDs drivers were loaded. If it displays a question mark then either an unsupported removable drive
was encountered, the disk has a foreign driver on it, or the extension could not allocate itself enough memory.
2) The Desktop icon representing removables mounted with an HDT Extension-loaded driver is the default icon stored inside HDT Extension ( not one chosen by HDT Primer).
3) The Multiple Bus Support checkbox allows HDT Extension to scan and load drivers for drives on all alternate SCSI buses which are fully compliant with SCSI Manager 4.3. (This will mount drives at identical SCSI ID's on different SCSI buses on the Power Macintosh 8100/80 or Quadra 900/950 with the Power Macintosh Upgrade Card.)
HDT LightShow™
---------------
1) Modem port accesses are indicated by an icon.
2) The dot uses the least amount of CPU power and causes the least amount of performance degradation.
HDT Mounter™
-------------
1) This is a new utility program that is not documented in the manual. It is designed to allow you to easily mount and control partitions without running HDT Primer. You can now store away HDT Primer to prevent novice users from exercising any of the more dangerous functions.
2) After launching HDT Mounter, you will be given a list of partitions on the disk. You can mount a partition by clicking once on the partition name and then selecting the "Mount" button or by double clicking on its name. You can change the bootable and automount flag of partitions by toggling them in the list. The pop-up menu at the top of the display allows you to switch to another online drive.
3) Power user keys include: the up and down arrow to scroll through the list, Return to mount a partition and tab to switch drives, Command-Tab switches between the different SCSI buses available if multiple SCSI buses are supported on your particular computer, Command-Q quits the program.
4) This program will only mount partitions on drives controlled by an HDT driver.
5) Clicking on one partition to set the bootable attribute will disable the bootable attribute for any other partition. To set multiple bootable partitions, hold down the shift key.
6) For quick access, we recommend that you put this utility in the Apple menu under System 7 or you could use a macro program to define a launch key for it.
7) HDT Mounter is designed to mount only partitions created with the same version of HDT Primer.
HDT Primer™
-----------
1) If you are having problems running out of System Heap space under System 6 Finder, try running MultiFinder instead; it handles memory much better.
Alternatively, You can use HDT Util to increase the System Heap size. System 7 has no such problems.
2) In the predefined partitions dialog that is brought up after formatting or initializing, there are now two A/UX 2.0 setup options:
A/UX (Min Mac) creates all standard A/UX partitions and a small 2048K Mac Partition.
A/UX (Max Mac) creates all standard A/UX partitions and puts the balance in a large Mac Partition.
3) All icons on a single drive are the same. To have different icons for different partitions, use System 7's ability to cut and paste icons.
4) The Configure Driver Test needs more memory if you are testing a drive with >512 byte/block blocksize. Increase the application’s memory size by using "Get Info " from the Finder File Menu.
5) When taking over a drive with multiple Macintosh HFS partitions, the default boot partition is the first HFS partition in the list. Use the Modify button in the Partition Directory Window to specify a different boot partition.
6) The compact driver option in the Configure Driver dialog described in the manual no longer exists because it is not necessary.
7) If you create more than 10 equal sized Macintosh partitions, only the first ten will be marked as "automount".
8) In order to resize and/or create partitions on a hard drive, you may have to start up and use HDT Primer from a different hard drive. If you only have one hard drive, you need to start up from a floppy disk and run HDT Primer from a floppy disk as well. Instructions for preparing a boot floppy are above.
9) On drive of greater than 1 GB capacity, the driver partition must reside in the first 1 GB of disk space or else the Macintosh cannot load it. Check the ordered list in the Partition Directory Window and ensure that this is true.
10) Versions 1.1 and higher of HDT Primer will install a PowerBook sleep compatible driver. Use Update Driver to update older drivers to the latest revision.
11) Formatting a MOST 3.5 Optical drive will cause a format configuration dialog box to appear. You can alter the number of groups within this dialog.
12) Formatting an 800K or 1.44 MB floppy in an INSITE I325VM drive will default to the regular Macintosh floppy format. If you use the Standard Partitioning and Maximum Macintosh preset partition method, the floppy can be used in a regular Macintosh floppy drive. If any custom partition method is used, the floppy can only be used in the INSITE I325VM drive. Custom partitioning is required to boot from a floppy disk in the INSITE.
13) A/UX 3.x compatibility. Apple includes a universal formatter/partitioner with A/UX 3.x. FWB recommends that you use this program to install A/UX 3.0. If you need to create several Macintosh partitions on the drive, you can do an install HDT driver onto that drive. You should then convert the type of Free Slice partitions to Apple_Free and create new Macintosh partitions. A/UX 3.x uses an Apple driver that does not recognize password protection or encryption. The program mounts protected partitions and asks if you wish to initialize them. Make sure you click CANCEL!
14) ProDOS partitions for the Apple IIe Card on the Macintosh LC/LCII/Performa 400
can be created with HDT Primer. The 'ProDOS File System' extension must have been installed in order for these partitions to be mountable.
15) Allow Disconnect. (SCSI Manager 4.3 only) The Allow Disconnect check box in the Configure Driver window allows the FWB driver to give permission to the drive to disconnect from the SCSI bus while the device fulfills the request. The resulting idle SCSI bus gives the system the opportunity to issue other SCSI I/O requests to other devices thereby increasing I/O throughput. Unfortunately, some older drives do not handle the disconnect privilege correctly. Run the Test function in the driver configuration dialog to ensure that your device handles disconnect satisfactorily.
16) SCSI Bus Menu. SCSI Bus Menu allows HDT to support computers with multiple SCSI buses. Additional SCSI buses can be formed with cards installed in your PDS and NuBus expansion slots on PowerPC Macintoshes and Macintosh 660AV and 840AV. The additional SCSI buses must be SCSI Manager 4.3 compatible and the accompanying PDS and NuBus card software must have loaded its SCSI Manager4.3-savvy drivers during bootup time. Refer to your PDS or NuBus SCSI bus hardware and software installation manual for more details. FWB’s SCSI JackHammer is fully compatible with this option.
17) EMERGENCY boot partition. You have the option of selecting a partition to boot from by simultaneously pressing Shift-Command-Option-E and a number from "1" through "9" while in the early stages of startup. In order to use the feature, the drive containing the alternate boot partition must have been selected as the Startup Disk via the Control Panel and the partition must contain a valid System Folder. Each number from "1" through "9" corresponds to the ordered list of HFS partitions as displayed by HDT Primer. This feature is ideal for creating an emergency partition that contains a bootable system folder and disk recovery utility. If your machine crashes at startup, simply reboot the machine and hold down the appropriate key combination to boot from the emergency volume that contains your recovery tools.
18) At Ease and HDT drivers. HDT drivers are compatible with At Ease for Workgroup's Lock Startup Volume security feature. It is important that you disable the Lock Startup Volume security feature through At Ease BEFORE proceeding with a HDT Primer Update Driver or Install HDT Driver.
19) Update or install HDT 1.5 or higher drivers to fix and avoid Apple's HFS mount volume problem that inadvertently prevents booting from improperly shutdown drives.
20) If you are creating a volume between 2 and 4 GB on a System that supports it, keep in mind that you need to make sure you do not startup from an older System that does not support volumes larger than 2 GB. You may get unexpected disk full error messages!
HDT Prober™
-----------
Power user keys:
Return=Mount the selected drive, Arrow keys=Select a different drive, Option-Return=Mount all drives, Cmd=Select Next SCSI Bus.
HDT Util™
---------
New menu option: Adjust Internal HD Delay - Allows you to set the amount of time the computer waits for an internal drive at SCSI ID 0 to become ready for bootup. (Macintosh II family and newer)
HDT World Control™
-----------------
1) After changing parameters in page 3 or 4, you need to reformat the drive to make the changes appear.
2) The Read Capacity item under the Commands menu is now Read/Change Capacity. You can now adjust the capacity of drives that support these changes. If you have used a non-512 byte blocksize and have run a program that caused the capacity of your drive to shrink, you can now recover the lost capacity with this command.
3) Mode Page 29 parameters for Ricoh Hyperspace:
PFRINH - Prefetch Read Ahead Inhibit
VERE - Write Verification Enable
SPERA - Speed Erase Enable
VWE - Virtual Write Enable
4) Mode Page 8 Additional parameters for SCSI-2 Drives:
IC - Initiator control. 1= Use number of cache segments, 0=Use adaptive algorithm
ABPF - Abort Pre-Fetch
CAP - Cache Analysis Permitted. 1= enable
DISC - Discontinuity
SIZE - Size Enable
FSW - Force Sequential Write
DRA - Disable Read Ahead
5) DEC Thermal Recalibration. The DEC Thermal Recalibration command in the "Command" menu TEMPORARILY disables the drive's automatic thermal recalibration capability for 15 minutes. This feature allows you to perform disk intensive operations more efficiently for a short duration. The drive will automatically enable its thermal calibration capability 15 minutes after being disabled.
Compatibility Notes
------------------
1) Quadra 840AV - Be sure to use System Enabler 088 version 1.1 or newer. Previous versions contained quirks that could inhibit correct system operation, primarily when no monitor is connected to the built-in video port. Updates are available on Applelink or from your authorized Apple dealer.
2) SuperATM 3.5 - Does not perform asynchronous I/O correctly, so it does not work on the JackHammer and the 840 AV. Call Adobe for an update to 3.6 or newer.
3) At Ease for Workgroups 2.0 - Do not use the Lock hard disk at startup feature with drives on a 4.3 bus. The program is not SCSI Manager 4.3 savvy.
4) QuickTime™ - QuickTime 1.5 has a 'quirk' that causes drivers that support true background asynchronous I/O to fail under some rare conditions. Upgrading to QuickTime 1.6 or newer fixes the problem completely. QuickTime 1.0 does not do asynchronous I/O, hence is fully compatible as is.
5) SyQuest 88 cartridges - HDT 1.5 Primer cannot access SyQuest 88 cartridges previously formatted with block size other than 512-byte block. Use pre-1.5 versions of HDT Primer if you need to perform HDT Primer functions on this type of cartridges.
6) AppleShare - It is suggested that volume sizes on AppleShare servers be kept at or below 2,066,441 Kbytes to avoid a limitation of Apple File Protocol. Volumes larger than this will erroneously show file and folder information on remote machines.
7) Stuffit Deluxe/Stuffit Expander - Versions 3.0.X erroneously reports a data integrity error after decompressing files from encrypted volumes on systems running SCSI Manager 4.3. As a workaround, decompress the file from an unencrypted volume or alternatively disregard the message.
8) HDT 1.5 & 1.5.1 drivers are incompatible with MindVision's Stacker 1.x product on systems with SCSI Manager 4.3.
