Tech Tool vs. Disk Utility test results

by bshishka / September 18, 2009 4:30 AM PDT

My Macbook Pro, using OSX 10.4.11, keeps on failing the volume structure test on Tech Tool Deluxe (I tried both 3.1.2 and 3.1.3). My version of Tech Tool does not have repair capability, so I went to the Disk Utility function on my Mac startup disk, ran Repair Disk, and it told me "no repairs were necessary." Why the discrepancy? Should I be worried about my hard drive? Should I spend money on the version of Tech Tool that does repairs?

Thanks for advice anyone may have!

In reply to: What version of TTP

I don't remember whether my version of Tech Tool Deluxe was already in my Macbook, or whether it came with my Apple Care plan, but it has only "diagnostic capabilities." When the volume structure fails, a message comes up telling me that if I want repairs I need to go online and download a version with "diagnostic and repair capabilities." But I'm unable to download that because my Apple Care is expired. In any event, is Disk Utility more or less reliable than Tech Tool?

Disk Utility & TTP

TTP may fix a few more things than Disk Utility and is designed to do a similar job in a different way.

DU is the first line of defense, while TTP, and others, are the bigger guns in the arsenal.

Features of TTD

TechTool Deluxe offers these features:
Repairs Directories by Rebuilding
Volume Repair Preview Report
Bad Block Detection on Drives
Checks the Drive Mechanism
Checks USB Functionality
Checks Memory
Checks Video RAM
Checks CPU
If you got it with Apple Care Protection plan, it should have the above features. You might have just a demo version. If this is correct, I'd rather get Disk Warrior; most people like it better, although I never had a problem with TT Pro (never bought a deluxe, a stripped-down version).
