Hard Disk ToolKit v2.0.5 Release Notes
1/3/97 Copyright ©1991-1997 FWB Software, LLC
----------------------------------------------------------------------------
Additional features/notes of Hard Disk ToolKit not mentioned in the User
Guide.
Note: IDE is also referred to as ATA.
Hard Disk ToolKit Installer
- The Installer application installs the Hard Disk ToolKit applications,
control panels, and system extensions. It will not install hard disk
drivers.
- The Installer cannot install the FWB Tools Extension, the FWB IDE
Extension, or the FWB TurboBoot Extension if the startup volume is locked
(files cannot be added to the volume) or if you start up from a CD-ROM. Do
not choose the Easy Install option to install RAID ToolKit if your startup
volume is locked. If using Custom Install, do not select the FWB Tools
Extension, the FWB IDE Extension, or either of the FWB Tool Manager Pro
options if your startup volume is locked.
- Before the Installer installs any of Hard Disk ToolKit 2.0.5’s
applications and extensions, the old 1.x extensions, preferences, and
control panel items will be moved into a folder called Disabled FWB Items.
This folder will reside in the System Folder of the startup drive.
- If you are upgrading from Hard Disk ToolKit 2.0 to 2.0.5, the Hard Disk
ToolKit 2.0 folder will not be affected by the Installer, but the extensions
in the Extensions folder in the System folder will be replaced with new
ones. We suggest you delete your Hard Disk ToolKit 2.0 folder after copying
any of your data files you wish to save to the "Hard Disk ToolKit 2" folder.
- When you install FWB Tools (either by Easy Install or Custom Install), any
copies of FWB Tools-PE (from Hard Disk ToolKit-PE 2.x) will be removed.
Where have the FWB (Hammer) Logos Gone?
We’ve made minor changes to the interface in this version to reflect FWB
Software’s new logo and corporate identity. Specifically, we’ve updated all
instances of the "crossed hammer" icon with the new FWB Software, LLC logo.
Hard Disk ToolKit
- Hard Disk ToolKit, the FWB Crisis Tool, FWB Mounter, and FWB IDE Extension
explicitly support IDE drives. The other components of Hard Disk ToolKit do
not.
- If you define custom settings for your disk driver (such as blind
transfers or verification after writes), when you update to the latest FWB
driver, the settings are reset to the default for that drive. This ensures
the highest degree of safety for all supported drives, which use the
thoroughly tested optimal settings contained in the Device Data and Device
Data ATA files. Please note the settings before updating the driver and
reset them to your custom settings after updating the driver.
- If it appears that you have plenty of free space on your disk, but
installing or updating a driver fails, defragment your disk and try the
operation again. If this fails, you may need to back up your data and
reinitialize your disk to install the latest FWB driver. Also see the next
item.
- Norton Filesaver makes an invisible file near the end of the partition. If
there is data near the end of the HFS partition, we cannot shrink it, which
may be necessary for driver updating. Here are the steps to work around this
problem:
1. Turn off Norton Filesaver at minimum for the volume whose driver you are
updating.
2. Run a disk optimizer, like Norton Speed Disk or TurboDisk (part of FWB
Turbo ToolKit).
3. In your disk optimizer, turn on the option to erase unused space.
4. Optimize the disk.
5. Try to update the driver with Hard Disk ToolKit again.
The above steps usually work. A file was probably in the way.
- If you are using System 7.5.2 or later and a volume fails to initialize,
please note that Apple’s disk initialization routine has recently changed.
Although it’s faster, it requires more free memory to perform the operation
under System 7.5.2 or later. If an attempt to initialize fails, try again
after freeing up more RAM by quitting all applications and restarting Hard
Disk ToolKit, or by restarting the system with extensions off (by holding
down the Shift key during startup).
- In BenchTest, the largest transfer size accepted is 65,535KB (64 MB).
- When performing write-enabled media scanning, Hard Disk ToolKit prevents
the user from switching to other applications. This is to minimize the risk
of data loss should a disk error occur during a write operation.
- If a CD-ROM changer or jukebox is connected to the system when Hard Disk
ToolKit is launched, the main window may take longer to appear. If there are
CDs loaded in the changer or jukebox, the startup screen may remain
displayed for up to 15 minutes while Hard Disk ToolKit scans for detailed
information on all attached SCSI LUNs. With fewer CDs loaded in the changer
or jukebox, the Hard Disk ToolKit main display window may appear sooner.
- Hard Disk ToolKit will install an IDE driver and a SCSI driver on all
removable media and all IDE drives. Dual drivers allow you to interchange
removable media between IDE and SCSI removable drives and to use
IDE-configured laptops in SCSI Disk Mode.
NOTE: If you use a Macintosh PowerBook with an IDE drive (such as a
Macintosh PowerBook 190 or 5300), and you partition the drive into multiple
volumes, then the Macintosh PowerBook cannot be put in SCSI disk mode when
using the Hard Disk ToolKit driver. There is no problem if the drive
contains just a single volume.
- Hard Disk ToolKit 2.0.1 can create custom partitions for use with MkLinux.
Format the drive. When the Create Volumes dialog appears click "Cancel".
Manually create the following partitions:
Volume Type: Apple_HFS, Name: "MacOS HFS Boot partition" - At least 50 MB
Volume Type: Scratch, Name: "root", Type: "Apple_UNIX_SVR2" - At least 100
MB
Volume Type: Scratch, Name: "usr", Type: "Apple_UNIX_SVR2" - At least 200 MB
Volume Type: Scratch, Name: "swap", Type: "Apple_UNIX_SVR2" - 64 MB
- A generic document icon may appear on your Desktop instead of the colorful
disk icon after successful autoinitialization of your device. This is a
problem seen on early System 7 versions and is fixed on System 7.5.3 and
later. Please see "How to Use Cool FWB Icons" for step-by-step instructions
on how to replace the generic document icon with one of our colorful Desktop
icons. (This file is not available in the Hard Disk ToolKit 2.0.1 Update --
please see your Macintosh User Guide instead.)
- If you are using a Power Macintosh without the ObjectSupportLib file
installed, drag-and-drop is not supported.
- If QuickHelp refuses to launch, it may either not have enough free memory
to launch (quit unnecessary applications or activate Virtual Memory and
restart your system) or not be installed (reinstall QuickHelp from the
installation disks).
- The password dialog box will still come up at boot time on a secured
volume (password only or encrypted) even if its automount option is
disabled. Hit "Enter" to continue without mounting the volume.
IDE Driver
- The installed IDE driver is configured automatically for optimum
performance for a given IDE hard drive. However, the IDE driver will be
configured conservatively to work reliably on unsupported IDE hard drives.
You can manually tune the IDE driver by using the "Configure Driver" feature
in Hard Disk ToolKit; you can greatly improve IDE drive performance by
enabling the write cache and by modifying the R/W Multiple and PIO or DMA
settings. The following are hints for improved IDE drive performance:
1) Enable the write cache.
2) "R/W"- in general, larger "R/W" values improve drive performance.
3) "PIO/DMA" - in general, larger PIO or DMA values result in better
performance.
4) PIO vs. DMA - if you know you have Apple’s latest ATA Manager that
supports DMA, opting for the "DMA" setting results in more efficient IO and
greater data throughput. At the time of this release, only the ATA Manager
version shipped with PowerMac 5400 supported this capability.
Beware that some drives do not behave correctly at some of the more
sophisticated settings, so back up your data before experimenting.
- When setting Read/Write Multiple in the "Driver Configure" dialog for ATA
devices it is important to test the performance of various settings to
achieve best performance. The largest choice is not always the best for a
number of reasons, including
- the speed of the computer
- the capabilities of the system’s ATA hardware
- the choice of PIO transfer mode
R/W Mulitple choice has no impact upon performance when a DMA transfer mode
is selected. In most cases, a R/W Multiple of 8 delivers the best
performance on most Macintosh models.
TurboBoot
- TurboBoot should not be enabled if Netware 4.1 client software is
installed. There is no problem with Netware 5.0 client software.
FWB IDE Extension
- FWB IDE Extension should be installed only on PowerBook 5300 and PowerBook
190 laptops that are configured with removable media drives.
- Removable cartridges that do not contain an IDE driver must not be
inserted in removable drives when the machine is starting up or else they
will not be mounted. Please insert cartridges after the Desktop appears.
This applies to cartridges, not canisters.
- On PowerBook 5300s: If installed, the FWB IDE driver will load at startup,
even if the computer was started without a cartridge in the IDE drive.
FWB Crisis Tool
- The driver that FWB Crisis Tool installs is configured conservatively to
enable it to work with almost all hard drives. Use the "Configure Driver"
feature of the main application to fine tune the driver configuration for
better drive performance.
PC Card (PCMCIA)
- PC Card (PCMCIA) devices on PowerBooks (PB190 and PB5300) are not
explicitly supported in this release. However, Hard Disk ToolKit does not
prevent you from setting up and installing an IDE driver on a PC Card
device. Proceed at your own risk.
- Under limited testing, we have had some success with the SyQuest SQ-1080.
A system can be installed. "Put Away" or "Cmd-Y" ejects the PC Card device.
Holding down the option key while dragging the Desktop drive icon to the
Trash ejects both the PC Card device and the removable media. Again, we do
not claim support for PC Card devices on this release, so proceed at your
own risk.
Miscellaneous Compatibility Issues
- If you are using System 7.5.x, we recommend that you update to the latest
Macintosh System (version 7.5.5) available on many online services and
directly from Apple. Refer to Apple’s System Update Overview and
Installation documentation for additional information.
- For maximum performance and compatibility, owners of FWB’s NuBus SCSI
JackHammer should update all devices on the JackHammer bus with Hard Disk
ToolKit 2.0.1’s driver. Some third-party drivers erroneously reduce the
amount of System heap space available for drivers and extensions. This can
prevent Hard Disk ToolKit from loading any additional devices on the bus.
Simply update all devices on the system with the Hard Disk ToolKit driver to
avoid this problem.
- Mounting devices in FWB Mounter and FWB Crisis Tool: When in Device view,
you can only mount volumes that would normally mount at startup. If a
particular volume doesn’t mount when you select a device in Device view and
click the Mount button, you must switch to Volume view, and mount the volume
from there.
If the device is controlled by a Hard Disk ToolKit 2.x driver, you can
activate the volume’s Automount option using the Change Attributes command
in the Volumes menu in the main Hard Disk ToolKit application. (You may also
double click a volume.) The Volumes menu is available when the Selector
window is in Volume mode. Click the Automount checkbox to enable this option
(enabled means the checkbox has a check in it).
- Most disk diagnostic and repair utilities currently available do not
properly recognize volumes that have capacities larger than 4 GB or
allocation block sizes larger than 63.5 KB. Some utilities may erroneously
report such volumes as having numerous serious problems with their master
directory block, extents, and directory contents. Norton Utilities 3.2.1 or
later has been updated to handle large volumes.
- Contrary to the System 7.5.3 release notes, the original models of Power
Macintoshes (6100/7100/8100) do not support volumes larger than 4 GB under
System 7.5.3. To determine the largest volume supported by your current
combination of Mac OS System Software and Mac OS-compatible hardware, run
either the main Hard Disk ToolKit application or FWB Mounter, open "About
Hard Disk ToolKit..." (or "About FWB Mounter") under the Apple menu, and
select the "Info" (or "System Info...") button.
- The Sync-Cache option in Driver Configure is primarily intended for use on
devices that are connected to the fast internal bus of the PCI Macintosh.
Some users report sporadic data corruption during shutdown on these machines
due to incomplete flushing of the write cache. Some older devices do not
support the Sync-Cache option. If it defaults to "on" (box is checked), the
drive supports it. If the box is not checked for a device, turn this option
on at your own risk.
- You should not use older versions of RAID ToolKit, Hard Disk ToolKit, or
Hard Disk ToolKit-PE to modify 2.0.5 or newer formatted drives.
- Early models of the Fujitsu IDE DynaMO drive (model M2541B) are
incompatible with the PowerBook 190.
- IDE-configured models of Macintoshes create and support a type of HFS disk
configuration that has no disk partition map structure; it contains one
large HFS volume. Hard Disk ToolKit does not explicitly support such a disk
configuration but it will allow you to reconfigure the disk to a standard
configuration.
- In some situations, removable media with a pre-Hard Disk ToolKit 2.0 or a
non-FWB driver may not eject when you drag all its volumes to the Trash. If
you turn on the drive that contains the media after your computer starts up
or if you insert the media after the computer starts up and you mount one or
more volumes on the media with Hard Disk ToolKit 2.0 or HDT Tools, then the
media may not eject when you drag its last volume to the Trash. To fix the
situation, update the driver on the media to Hard Disk ToolKit 2.0 or later.
- If you have FaxSTF on your system, check that you are running version
3.2.2 or later. Earlier versions prevent FWB Tool Manager from launching
properly.
- Inside Macintosh IV-style partitions (circa 1986) are not supported by
Hard Disk ToolKit 2.0.5. Removable cartridges partitioned in this style will
not mount. Hard drives and removable cartridges cannot be updated to Inside
Macintosh: Devices format (a.k.a. Inside Macintosh V-style) by Update
Driver. Please backup and re-initialize hard drives and removable cartridges
to bring them into a modern format.
- You cannot update the driver of a Hard Disk ToolKit 1.8 level 2 encrypted
volume with the Hard Disk ToolKit 2.0.5 application. You must first decrypt
the volume using the Hard Disk ToolKit 1.8 Primer application, and then use
the Hard Disk ToolKit 2.0.5 application to update to a Hard Disk ToolKit
2.0.5 driver. After updating to the Hard Disk ToolKit 2.0.5 driver, you may
encrypt the volume again.
