Micromat TechTool Pro 4 (Mac) review:1 stars (sucks) - This program doesn't seem to work on my dual 800 mhz PowerMac. I updated to 4.0.4. I'm running Tiger. I tried recovering a file by scanning a volume. The program just hangs. 1 stars (Steer clear) - I wish I had read these reviews before buying Techtool Pro. It seems rather like a defective product. I had a drive that wouldn't mount, and TTP recognized it, and acted like it could recover it, but when I switched from "Drive" mode to "Volume" mode, the drive was no longer visible to the software, so it wouldn't perform any tests.
(In Drive mode, the problem drive passed all the hardware tests multiple times)
I executed the data recovery routine (which took literally all night to run on my 40GB drive, and it found 700+ arbitrary recoverable files from the thousands I had on the drive. It didn't retain the filenames, so it was a crapshoot when recovering any of them (most were superfluous utilities and Word docs, rather than my important files).

If you have a defective drive, put your money toward a new drive, rather than this gamble.4 stars (This is the only game in town for a general Mac utility) - In an earlier review I lamented how Techtool had seemed degraded in its performance since its upgrade to vers. 4.0 and Mac OS X compatibility. I have since learned that Symantec, maker of Norton Utilities, has indeed decided to no longer upgrade their general utility program. (According to news reports, they will continue to upgrade their virus and Internet Security software.)So what does this mean for Mac users? For one, DiskWarrior is a must have. As for Techtool, there's almost no choice - you have to have a general utility that's more powerful than Apple's rather weak First Aid. Here's hoping that Micromat comes up with a good update to Techtool and gets it back to the days of when it was arguably the best utility for the Mac.
