Hello Anne: I cannot say much about DiskWarrior except it is the best for what it does from all I read. I have the old version for OS 9, and the box is still wrapped in plastic.

In OS X, First Aid is part of Disk Utility. Open Disk Utility and find the First Aid tab or button, depending on how Jaguar does it. > 2.

If "bootable" is the difference, for the update price, I would go for it. You would end up with v3.0.3. I do not see info on a 3.1 or 3.3. > 3. Any opinions on which utility/utilities/combination are better to > have on board? (Norton, Techtool Pro, etc.) Avoid Norton like the plague, actually there is no suitable version for OS X. After updating DiskWarrior, it is adviseable to have TechTool Pro as well because it does many different things that DW does not.
