Drive Genius 4 (Mac)

Didn't help with my computer problem, so I'm disappointed, and I considered it over-priced compared with similar gadgets.

I own several MacBook Pros and my ultimate defence against disaster is Diskwarrior, which also comes on a memory stick. Drive Genius is very similar in function and presentation and it too is now available in memory stick form. Which is best, Diskwarrior or Drive Genius? I can only add that I have known and used Diskwarrior for longer than Drive Genius. Both are capable of restoring a seriously sick Mac' back to rude health.Unlike regular applications, each memory stick includes a mini version of OS X along with a suite of diagnostic & repair routines. Rather than attempting to boot a sick Mac' using its internal drive (mechanical or electronic), the Mac' is booted from the memory stick and the included diagnostic & repair routines bring the Mac' to perfect health, whereupon, the Mac' is restarted from its on drive.Drive Genus (or Diskwarrior) are not software tools that will be used a great deal. Hopefully they will never be used but computer disasters do happen. I cannot decide which is better, Drive Genius or Diskwarrior, but in my experience both work remarkably well. I have therefore given Drive Genius top marks.Please note, neither of these software tools will resurrect a Mac' that has suffered a hardware failure.
