Another powerful feature of ActiveSMART – Disk Space Usage Analyzer. It quickly scans the hard drive and show a graphical overview of disk space usage, using TreeMap technology. Now you can see how files and folders use the disk space and which of them are space wasters.

Easily find out which files and directories using up all your hard drive space. Discover where all your disk space is going with built in folder size utility.

Automatic disk check-up and hdd temperature monitor

Active SMART supports automatic disk check-up on system loading, constant tracking of the disks state with an interval varying from 1 minute to 99 hours, as well as performing a quick scan of the disks, in order to save the resources of the weaker machines.

Emergency system shutdown in case of hard drive overheating

Active SMART will suspend (using Hibernate mode) your PC automatically if the hard drive becomes too hot. This saves your important data and prevents the hard drive possible failure.

And even more features included

Secure file shredder using military grade algorithms allows deleting files and folders without any traces. See at a glance Performance, Health, Temperature and Free Space of all your hard drives.
Check the hard drive age.
Check amount of bad and reallocated blocks on the hard drives.
See if the disk has unstable sectors that going to fail.
S.M.A.R.T. attributes and hard drive temperature lifetime chart.
Email notifications about hard drive status and more features.


If ActiveSMART is not installed on the user PC/laptop, then the user doesn’t receive any hard drive status information. Any warning or alerts from S.M.A.R.T. of the hard drives will be ignored.

If ActiveSMART is installed, it retrieves all vital S.M.A.R.T. information from hard drives, analyzes it and calculates failure possibilities using special algorithms. The user will be notified about any potential disk emergency situation immediately.



ActiveSMART not only the harddrive tester, but constantly monitors the disk status using S.M.A.R.T. system and various diagnostic algorithms.


Find out what’s using up all your hard drive space in just one click. Built-it disk audit tool shows all files and folders and disk space they are using. Powerful folder size utility built in. Monitoring the hard drive space is never been so easy.


Built-in file and folders shredder tool wipes files and folders permanently using special, industry grade file shredding algorithms. ActiveSMART enables you to securely erase your sensitive data.


Prevent your hard drives overheating using built-in Hard Drive Temperature Monitor. Flexible disk temperature alarms, temperature history and current disk temperature included.


ActiveSMART is carefully optimized to use as low as possible resources on laptops. Special energy saving mode is automatically activated when notebook is running on battery.

“Active SMART is the most useful product I have purchased in 20 years of technical computer involvement. A truely useful product.”

Paul Ryan

“I’ve been in IT business for a decade and a half; I’ve almost never come across such a really essential piece of software as Active SMART. One of my Seagate HDD’s was dying, I was in search of a SMART tool, I was taken to your web site thanks to a Google query, I bought your tool online, and it quickly confirmed my guess. Thanks for such a useful, lean & mean utility.”


“While most computer users forget there hard disk exists, more interested in the software it contains and general PC performance speed, ActiveSMART is one of the most useful and intelligent products available. ActiveSMART is a GREAT comfort and in my personal case as a professional computer user (SEO), I can at last stop worrying about the state of my hard disk and get down to work. My deepest compliments. ActiveSMART is VERY impressive.”


“Over the last year, I have had the hard drive fail on two different laptops. After doing some research on the net, I discovered that overheating is a major cause of hard drive deterioration and failure. Given that this is widely known, it is a glaring error for operating systems not to include this feature. After all, cars have a temperature gauge; it seems only logical that an operating system should have a temperature gauge. Active Smart software corrects this glaring error. Thank-you for making this software..”

“I was searching for a low level format utility for my external hard drive and discovered ActiveSMART. It quickly hinted that the problem is in disk overheating. I changed the USB disk case and the disk status went okay! Actually, ActiveSMART saved me from buying the new hard drive. That’s great.”
