Hi. I was wondering, what's the best option out there? when it comes to check the hard disks health? (I mean internal and external, i.e. primary disk and attached storage.) I've read that Disk Utility does the job pretty well, though to be honest I'm totally a noob when it comes to hard disks. Is the verify disk option going to really tell me if a disk is going to die soon? I want to be extra careful when it comes to handling information on those drives. Or should I use an additional software to make 100% sure that my disks are working ok? (Obviously I know it's impossible to know when a hard disk will fail, but we are talking about probabilities here.) And one last thing. Why can I verify my primary disk from Disk Utility, but not my external ones? I mean, I can only verify each of the partitions on them, but no the actual disks.
