You beat me to it, Bruce. Yes, the first and best source of information about DiskWarrior is the manufacturer, Here's a link to Alsoft's system requirements page: <http://www.alsoft.com/diskwarrior/requirements.html> As can be seen quickly by browsing that page, there are a lot of tricky things to figure out when trying to run the various versions of DiskWarrior on various versions of Mac OS. What you really want to do is to boot a Mac from the proper DiskWarrior CD or DVD so it can work its magic unimpeded by anything else. I sometimes run DiskWarrior from my main desktop iMac on another Mac via Firewire cable, but only when I want a quick fix. I use DiskWarrior 3.0.3 for OS 9 through OS 10.4 Macs that are set up as dual-boot machines. I use DiskWarrior 4.1 on OS X 10.5 machines, DW 4.2 on OS X 10.6 machines, and DiskWarrior 4.4 (the current version) on 10.7 through 10.9 machines. If Mac OS's Disk Utility cannot repair a drive, I boot from the appropriate DiskWarrior disk and let DW do its special magic. As Bruce noted earlier, DiskWarrior only repairs directories. It cannot perform magical repairs on disks suffering from hardware-related issues, such as bad sectors or slow reads/writes. However, I have learned from experience that if a hard drive that has been "fixed" by running DiskWarrior begins to have troubles again, it's a sign of either a failing hard drive or of improper shutdowns by the user. If DW finds and fixes "volume information" errors more than once, I begin to suspect improper Mac shutdowns by the user while the OS was still doing things. For example, I once was called into a local middle school's Mac lab, where half of the 36 iMacs would not boot properly, if at all. At first, I thought I was going to have to reinstall OS X 10.4, but after I ran DW on the first iMac, it booted and ran perfectly. Not much was found wrong and corrected, other than incorrect volume information. As I continued on through the rest of the iMacs, each one came back to life after DW corrected volume information errors. During the 20 or so hours I spent in that Mac lab that week, often taking apart the slot-loading iMacs to remove everything from tiny circuit boards to paper clips and sticky notes with "Help me!" written on them from CD drives, I discovered why DW was finding so many volume information errors. Several teachers who had come in with their classes were instructing their students to pull the power plug so as to shut down their iMacs when the end of class time bell rang! No wonder I had to go back and redo several of the first iMacs I had run DW on. On the other hand, if the Mac is being treated properly and is shut down correctly yet still is having problems that are fixed by running DW more than once, I immediately suspect the hard drive has bad sectors or other problems. At that point I pull out Prosoft's Drive Genius 3 (<www.prosoftengineering.com>) and boot the Mac from that disk. If a hard drive keeps having problems after Disk Warrior has repaired it, Drive Genius almost always finds either bad sectors or integrity (slow read/write) issues. Cheers!
