I was at the Apple store checking out new Tiger OS and happened to ask the tech guy's advice on new TechTool Pro 4.0.4. I had just been online for an hour reading bad reviews on TechTool, so I was curious of his take on it. He told me about DiskWarrior and said that it was superior to TT Pro. As you know, Disk First Aid does little to help or repair serious stuff, so, from what he said, DiskWarrior is a must-have tool to protect your hard drive. He really highly recommended it. The catch is, and I didn't ask, maybe they sell them there and he was just trying to talk me into buying one. (I avoid their high prices and buy everything on line anyway.) Too bad shipping prices are soaring!!

Disk Warrior was a life saver for Me.
My G4 Quicksilver developed a serious problem one day after giving
me no indication there was any problem in the offing. I make it a habit
of repairing my permissions about once a month, and thought that
would protect me.
After developing this problem, I did a disk repair using the native
disk repair in the utilities. I found I had a number of over lapped
extent files. God knows how I got those, or what they are.
Apple tech help advised me to get some software like Disk Warrior,
and that it might allow me to save my data, and not have to reload
the OS, and all my applications.
Disk Warrior was a snap to use. I graphed my hard drive first, and
found to be heavily fragmented. Then I did the repair of my hard
disk. And my computer booted right up, and none of data was lost.
In fact my computer went right back to operating like it had been.
With no lingering problem. And when I went back and graphed the
hard drive it was perfectly organized.
I would recommend this software to anyone. I plan to use it every
couple of months as part of a regular maintenance program for my
computer.

I'm not the kind (unfortunately) to always share my experiences, good or bad, with products. However, I must say that Disk Warrior is the BEST. My iBook had crashed, losing a year of research, two vacations' worth of pictures, etc. etc. [I'll never not backup again]. Disk First Aid and Apple's help desk were useless. I took it to professional data recovery people, who said that they'd charge me $600 whether or not they saved a damn thing. DiskWarrior for OSX did what the others couldn't -- it rebuilt my drive, and I got back every single file, zero loss. This product is truly miraculous!

The Most Amazing Piece Of Software Ever. If you catalog file is damaged, the only way to fix it is Disk Warrior. I F**ked up my mac and this prgram cleaned up the mess right away. A somewhat slow process but it never crashes and always work. I would never return it. Thank You Alsoft!

My experience shows this to be absolutely worthless software. I do not understand how anyone could give it a good review. I wasted money on it based on the reviews that I've read. It scanned my drive, pointed out three problems, and told me the drive was unfixable. I installed Tech Tools Pro 4 and it scanned the same drive, reported the errors and fixed them. Twice Disk Warrior has proven to be totally impotent. Walk on by this product and invest in Tech Tools Pro 4. Would that I could get my money back.
