Norton Disk Doctor可以安全并容易地诊断和修复各种磁盘故障。它将执行几项测试。检查从磁盘的分区表到物理表面的每一项目。如果Norton Disk Doctor找到一个错误，它在修复之前将通知你。如果你愿意的话，你也可以让它执行必要的修复。

Disk Doctor is to Disk First Aid what BBEdit is to SimpleText. It will find problems with your disks that you didn’t even know were problems (more on this later). Sure, Disk First Aid (DFA) can fix minor errors with a missing custom icon here and there, but Disk Doctor can find and fix much more. Everything from bad b-trees to bad file modification dates fall under Disk Doctor’s “I Can Fix This” list, and that’s impressive.
