Existing users, 
BEWARE OF THIS UPDATE!
TechTool Pro 4.0.4 was great on my 400 MHz PowerPC G3 running Mac OS X 10.4.2.
BEWARE OF THIS UPDATE!
When I downloaded and installed the update to TechTool Pro 4.0.5 the eDrive opened, but the "eDrive TechTool Pro 4 application" would no longer function. It would not open, even though it opened on my hard drive which opened the eDrive.
When I attempted to restart, it rebooted to the eDrive. The System Preferences button in the upper tool bar was non functional. Fortunately "Disk Utilities" on the dock opened, as did "StartUp Disk" which allowed me to escape the program and reboot to my hard drive.
When I emailed Micromat at what was previously a support email address, it bounced back. On going to support on the web site, my name and address was already entered in the support base, but it told me that I could not get support, since I had not registered the product. If that were the case, where did they get the demographic information? The product was ordered and mailed to me directly by Micromat! I reregistered the product. They got my demographic information when I originally registered TechTool Pro 4. Still no assistance after reregistration.
I have owned three different Micromat programs, and even a Micromat external hard drive. This update would lead me to warn those whose earlier version is working well not to update it. Beware of installing this update!
I read several negative reviews and installed it any way, since I was a long time Micromat product user. How naive. Such grief.
BEWARE OF THIS UPDATE!

TechTool Pro 4.0.5 Updater.app Nightmare - nicksrick
9/14/05Peter of the Micromat Inc. Technical Support Team told me that the reason I have suffered Update-malfunction grief, is that the original TTP 4.0 installer CD that I purchased installed Mac OS X 10.2 on my eDrive. He indicated that I needed to purchase a new TTP 4 installation CD that would remove the earlier installed eDrive and install a new one with a larger 5 GB partition. The installed Mac OS on the eDrive needs to be 10.3 or above.
The cost was $24.97 + S&H = $31.84.

TechTool Pro 4.0.5 Installer.app Nightmare - nicksrick
Buyer Beware! 9/13/05 Buyer Beware!Even the Full clean install of TechTool Pro 4.0.5 appears to have the potential to cause major grief!
The Micromat Inc. Tech support sent me a link to download the full installer of TechTool Pro 4.0.5. I was to uninstall TTP and then reinstall it for a "clean install".
The TechTool Pro 4 Installer.app appeared to be accomplishing it's tasks, both for installation and later installation. Registration was completed.
The program was opened and re-registered.
The Maintenance option in the Performance battery was chosen, and the computer restarted by booting on the EDrive, as before. Just as before the TechTool Pro icon in the dock bounced up and down, but no window opened. None of the choices in the upper bar were viable. I exited the eDrive by clicking on System Preferences on the Dock, choosing the Startup drive, and re-starting.
There appears to be a major bug in this program.
I requested a link to a full installer of the previous version of TTP 4.0.4 that worked fine until an attempt to update:
"Could you send me a link to download the previous version 4.0.4 (that I had before the upgrade) so that I could be able to get back to where I was before my increasingly greater frustration with your product?"
We'll see what the response will be.
Rick
