Hard Disk Sentinel Professional (HDSentinel) is a HDD/SSD monitoring and analysis application. Its goal is to find, test, diagnose and repair disk drive problems, report and display SSD and HDD health, performance degradations and failures. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and solid state disks inside the computer or in external enclosures (USB / e-SATA). Many different alerts and report options are available to ensure maximum safety of your valuable data.

The software monitors hard disk drive / HDD status, including health, temperature and all S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology, built in most hard disks and solid state disks today) values for each disks. Also it measures the disk transfer speed in real time which can be used as a benchmark or to detect possible hard disk failures, performance degradations.

Quote from a review where Hard Disk Sentinel received Editor's choice award:

 

"The price of one 1.000 GB HDD 130 USD

The price of your work saved files - hundreds or, maybe, thousands of hours

A solution to guard all this stuff : PRICELESS

This is the way I would describe Hard Disk Sentinel after some days of intensive testing.

Capable of monitoring fixed or portable hard disk drives ( USB ), Hard Disk Sentinel tests, finds and repairs errors and failures that might appear. It is the perfect data protection solution that complete its tasks in real time..."

  

HDSentinel is the perfect data protection solution: it can be effectively used to prevent HDD failure and SSD / HDD data loss because it has the most sensitive disk health rating system which is extremely sensitive to disk problems. This way even a small HDD problem can't be missed. The Professional version has scheduled and automatic (on-problem) disk backup options to prevent data loss caused by not only failure but by malware or accidental delete also.

Hard Disk Sentinel runs in the background and verifies SSD / HDD health status by inspecting the SMART status of the disk(s). If an error is found or unexpected behaviour is detected, it warns the user about the current situation and also can perform appropriate actions (for example, start an automatic backup).

Usually, hard disk health status may slowly decline, from day to day. The SMART monitoring technology can predict HDD failure by examining the critical values of the disk drive. Compared to other software, Hard Disk Sentinel detects and reports every disk problem. It is much more sensitive to disk failures and can display better and more detailed information about hard disk expected life and the problems found (if any). This is a more sophisticated way to predict failures than the "traditional" method: checking S.M.A.R.T. attribute thresholds and values only. For more information, please read how hard disk S.M.A.R.T. works and why Hard Disk Sentinel is different. Signs of a hard drive failure

The software displays the current hard disk temperature and logs maximum and average HDD temperatures. This may be used to check the maximum temperature under high hard disk load. For the importance of the hard disk operating temperature, see the Frequently Asked Questions. See the list of Features of Hard Disk Sentinel Professional or our products for hard disk monitoring.
