Your PC’s hard disk stores all of your relevant data, and any potential damage to the device has the potential of endangering your data, as well, unfortunately. On the other hand, a hard disk has a limited lifespan, and it will eventually get corrupted sooner or later. Therefore, letting your data depend on it is not the best option we recommend.

If you are not aware of the condition of your hard drives, you may not be able to save your essential data before it’s too late. You have to become conscious of the fact that not all hard drive crashes are random and this is why you have to know when it’s time to back up your data before it fails beyond return.

You really have to make sure that all your essential information is backed up before anything nasty might happen to your hard disk. A recommended solution is keeping tabs on your hard drive’s health so, in case something goes wrong, you will quickly be able to back things up.

Solutions & alternatives for monitoring your hard drives

Here are your solutions and alternatives for keeping an eye on your HDD’s health:

All last-gen drives come with a monitoring technology called S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). This tool is targeted at continuously monitoring a certain number of parameters on a hard drive. Various parameters can be efficiently monitored using S.M.A.R.T., and these also include read and write error rates, spin-up time, seek error rates, temperature, and more important elements.

To actually warn you when some of these crucial parameters are degrading or reaching their threshold you need a program that can track down all of these changes and that will also show them to you.

You must get the opportunity to test and see whether your hard drive is capable of safely storing your data, to have enough time to backup essential files and to start looking for a replacement in case it becomes necessary due to various reasons.

A monitoring program alone may be not fully capable of showing you whether the integrity of your files can be preserved on a particular hard drive. It’s an excellent idea to scan for unreadable or bad block of data with available tools at least once a month to make sure that your drive is not degrading and your data is not being lost.

S.M.A.R.T. for checking your HDD’s health

S.M.A.R.T. is the embedded monitoring system that comes implemented in most modern HDD or SSD, but unfortunately, it will only let itself be known to users only when an imminent hardware failure is on its way. All the main HDD manufacturers recommend an occasional check of your disk status and also running some surface tests and benchmarks.

We gathered a list of 14 tools for checking your HDD’s health, as well, as they can best predict and protect from the unavoidable circumstances of hard drive failure. Anyway, most of the utilities usually incorporate the built-in S.M.A.R.T. feature mentioned above, and it will definitely help them offer more information regarding indicators of disk reliability.
