Or your external hard disk no longer appears. Or your MP3s won't play... Or every time you look through your photos, your Mac crashes.

DiskWarrior repairs those cryptic errors reported by Disk Utility. Messages from your Mac such as "Invalid node structure" and "Keys out of order" may seem mysterious or even scary but DiskWarrior fixes these problems and many, many more. DiskWarrior saves your hard-earned money. You can try other utilities but you'll probably end up needing DiskWarrior to recover your data. You'll save money buying DiskWarrior first.
