I want to check the health so to speak of my hard drives on which my precious data is located.
I want to be prepared when one of them doesn't boot anymore and I don't loose the data on it.
I need legit tools and not maleware stuff this is why I ask here and not search google which is full of fake stuff.
I'd get the diagnostic tools available on the drive manufacturer's web site. And I'd pay attention to SMART details, particularly bad sector count.
There are other tools to measure speed. And other tools to inspect the file system and partitions, rather than the drive itself.
Problem is, hard drives quite often die suddenly and without warning. Healthy today by all accounts. Dead and gone tomorrow.
So the tools won't really keep you from losing data. The way to prepare for that is to back up your stuff so that all a drive failure means to you is that you have to spend money on a new drive and take the time to install it and restore your stuff from the backup.
Last price I saw for professional data recovery from a dead drive was $700 on up. Free tools may or may not help, but if you're backed up that really doesn't matter.
