But that is to be done before the problem :)īack to your case, I suggest you give Onyx a try to check the status of your HDD’s Smart status. Most of the benefit of TechTool Pro and DiskWarrior is to have am emergency plan in place in case of hard drive failure. In any case, since you want the free option, you will have to rely in your common sense and the tools you have (this is also true for the Shareware options, which really don’t seem to add much at this stage). I assume you are aware of the Shareware tools (Like the five mentioned in this article).
