Do you suspect one of your drives is about to request early retirement? Or maybe there's a "new noise" that catches your attention? Unfortunately, hard drives fail, and although in many cases they do so with a certain "spontaneity", the truth is they give off several warnings about their inevitable crisis. That's where tools like HDDExpert come in, reading the data recorded by the SMART system and presenting it to you clearly and simply.
Stories about hard drives going up in flames (metaphorically, of course) and users having nervous breakdowns (not so metaphorically) multiply day by day. Making backups is tedious and frustrating, but they're our first line of defense against an internal failure, and in the long run they can save us a few bills, not to mention time and headaches. I've personally seen hard drives fall apart just a few months after being installed, but in general, the age of the drive is one of the most important factors in determining its health. The SMART system isn't perfect when it comes to reporting, but its accuracy is high enough to know when it's time to take a closer look at a hard drive, or why not, at a solid-state drive.
All we need is a suitable program to read SMART, and although we've seen several in the past, I'd like to add HDDExpert, developed by KC Softwares. In addition to presenting the main SMART values, HDDExpert also shows the drive's temperature and an average of the number of cycles (on-off) and hours of activity. All drives can be accessed with a single click on their icon, and next to the model we'll find another icon similar to the PDF format, which triggers a web search for the manual with your default browser. The "Fans", "Spare" and "Backup" buttons take you to general searches on Amazon, assuming you decide to buy replacement hardware there.
As always, the most critical SMART numbers are sector reallocations (whether complete or pending), spin-up errors, and the count of errors that weren't or couldn't be corrected. HDDExpert highlights these elements in pink, and based on the overall state of the drive, it will make the necessary recommendations.
