MacFixIt Forums threads on TechTool

The Troubleshooting Software MacFixIt Forum has numerous threads on TechTool Pro 2.5.2 (a, b, c, d, e) and TechTool 1.1.9 (a, b, c). They cover reported problems and solutions for using this software with Mac OS 9, InDesign, FreePPP and more.

One more that I found especially interesting was titled "TechTool Pro 2.5.2 Rebuild Volume." It covers the problem of getting a Type 3 error when trying to Rebuild Volumes (as mentioned in the MacFixIt Extra on TechTool Pro 2.5.2).

Also check out the other threads mentioned in the MacFixIt Extra, especially this one.

And almost every one of these threads includes replies from MicroMat tech support!
