First download contains the utility only while the second download
contains the installer, extras and a bootable Mac OS 8.5.1 volume.

This PowerPC-only utility is for formatting hard drives into
partitions greater than 4 GB. There are many options to modify volumes
"on the fly" without having to reinitialize your entire drive.

Note: Third party (FWB) drivers will be installed and the Apple
Drivers will no longer be used for OS 8 & OS 9.

 * Once HDT is installed, you set everything up (partitions etc) by
   launching HDT from the installed application.
 * Since HDT is only for OS 8 and higher, if you have a partition for
   Mac OS 7 on your HD then you will still be using the Apple drivers
   for that partition. There will not be any conflict when using the
   different partitions with the different drivers.

\--------------------------------------------------------------------------------------------
Important:

Once HDT is installed on your main hard drive, if you still need to
boot from your Zip Drive you'll need to update the drivers for each
*individual* Zip disk that you wish to be bootable. If you don't
update the drivers, the Zip disks are still recognized and fully
useable, you just can't boot from them. Tip: You'll know when a Zip
disk is updated with the FWB driver; when restarting it will eject. If
you don't update the driver, and the Zip disk is in the drive when
restarting, it will not eject from the drive.

Note about the CD Drive:

Unlike the Zip Drive, your CD-ROM will continue to function as before
without any modifications. Therefore you will still be able to boot
from a CD if needed.

Version 4.5.2 requires OS 8.0 and higher on the target hard drive.

There is an [FAQ][1] on the RAID Toolkit here. The RAID Toolkit was
incorporated into the Hard Disk Toolkit after version 3.
