I've been using Disk Warrior from the earliest version 2. It worked fine until version 4 came out. It would slow down my mac and crash it so I had to reinstall OS X. After almost 4 years I have read all those "nice" reviews about this new update on version 5 and I purchased it again, which I regret now very much. Although, I have to say that It didn't crash my macs like version 4 did, but it still slows them down more then twice. Before I run DW 5 on my macs, I've tested the speed of the drives with 'Blackmagic Disk Speed Test' (this is a simple softwere to test read and write speed of your hard drive) and after running Disk Warrior 5 the speed of my macs become twice or more slower then it was before. I will never ever buy anything from Alsoft and would never ever recomend it to anyone.
