[Image: 5GIauRy.png]

Hard Disk Sentinel Professional overview

Hard Disk Sentinel Professional (HDSentinel) is a hard disk monitoring software with highest possible support of HDD/SSD/SSHD (hybrid) drives. Its goal is to find, test, diagnose and repair hard disk drive problems, report and display SSD and HDD health, performance degradations and failures.
Hard Disk Sentinel gives complete textual description, tips and displays 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, performance status,  provides detailed disk information, statistics, alerts and backup functions. The program also monitors all S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology, built in most hard disks, solid state disks and hybrid drives (SSHD) today) values for each disk. In addition, 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. It points on present or future disk problems like excessive temperature or degradation of disk health.

HDSentinel is a perfect solution to protect your data with the built-in sensitive hard disk health rating system which is sensitive to any hard disk problems and the backup options (pro version)

No need to use separate tools to verify internal hard disks, external hard disks, SSDs, hybrid disk drives (SSHD), disks in RAID arrays and Network Attached Storage (NAS) drives as these are all included in a single software. In addition Hard Disk Sentinel Pro detects and displays status and S.M.A.R.T. information about LTO tape drives and appropriate industrial (micro) SD cards and eMMC devices too.

Hard Disk Sentinel Professional PORTABLE version

This version doesn’t need installation and contains all tests, diagnostic functions, options and all features of the installed version except automatically start with Windows, use in Service mode and configure data folder location.

The portable version helps to diagnose hard disks in different systems. You can easily diagnose any problems of HDD and SSD devices without installation but notice that you can use it only one computer at any given time.

It can be effectively used from any removable device (for example pendrive) by system integrators and advanced users to periodically diagnose and test hard disk drives. However; it will not provide real-time protection offered by the installed version. Of course, this portable version requires a license similar to the installed version.  If you are planning to use both versions, separate licenses or Family license is required.

The Portable version can be used on unlimited systems, HDD and SSD  with only one computer at any given time.

Hard Disk Sentinel can communicate with all IDE, Serial ATA, NVMe, SCSI, SAS and most USB hard disk drives, SSD and hybrid drives (SSHD) to detect their status and temperature. Hard disk status are displayed immediately as you launch the application, there is no need to analyse hard disks for a long period. It displays the current and maximum temperature for the hard disk. It reads all general and vendor-specific attributes and monitor their values. For advanced users, all raw data are displayed also including power-on time and number of read/write errors. Hard Disk Sentinel interprets the performance and fitness related S.M.A.R.T. values and displays the calculated Performance and Health percentage, total power on time and estimated lifetime remaining.

Hard Disk Hardware and Software Tests

By using Hard Disk Sentinel, it is possible to start hardware hard disk self tests. These tests can be used to effectively find all hard disk problems because built-in hardware methods are used to verify hard disk components (for example heads, servo, internal buffer in the Short self test). The Extended self test also verifies the complete hard disk surface, finds and repairs all weak areas and re-allocates the possible bad sectors. This is not possible with the software-based hard disk surface scan methods (for example, by using scandisk).

Seek Noise Test

Seek Test - to verify hard disk noise, seek time performance and temperature. Longer tests can be used as very deep and intensive stress-tests for the hard disk and verify if additional cooling is required.

Acoustic Management

Offers option to control the acoustic level of IDE/S-ATA hard disk. It is possible to increase performance or make the hard disk drives more silent. Unique feature: control the acoustic level of your external USB hard disk (if your USB enclosure is equipped with one of the proper USB-ATA bridge chips which supports this feature).

Clock Synchronization

It offers option to synchronize the PC clock with an atomic clock via NTP (Network Time Protocol).


Hard Disk Sentinel is constantly improving. More features will be available soon. If you have any idea which can be useful, send to the developer to be considered.

API Interface For Developers

With the API it is possible to query detected hard disk information from the software. This way 3rd party software can log, display or otherwise process detected hard disk drive information including temperature, health and so.

Remote Monitoring

Hard Disk Sentinel Professional offers extensive remote monitoring capabilities. Hard disk status can be checked remotely by a web browser, even by a mobile phone or a PDA.

How does Hard Disk Sentinel work?

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.

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.

How to start using Hard Disk Sentinel?

Hard Disk Sentinel is designed to start automatically with the system and run in the background, to monitor hard disk information (temperature, health, performance, etc.) and report any kind of problems as early as possible.
Check the text description and health values reported for your hard disks / SSDs
Follow if Hard Disk Sentinel reports problems/recommendations, especially if it recommends backup.
Use test methods in Disk menu to reveal and fix possible problems.
Configure alerts to be notified about any kind of possible new problems (after verifying stable status of the hard disks)
Set up advanced functions (backup, daily status reports, remote status monitoring, etc.)
The Tray icon immediately reflects the problem by flashing a red X icon.
Hard Disk Sentinel displays a tray icon bubble with the error and the hard disk.
If the small status window is visible, the error of the problematic hard disk is displayed there.
The Professional version can also execute any external application or start backup operation immediately, for example to backup data immediately from the failing drive to another.

Text Description

Hard Disk Sentinel analyses the S.M.A.R.T. attributes provided by the disk and creates textual rating. This will include the problems encountered during the lifetime of the hard disk, spin up problems, data transfer errors and so on

Monitor (micro) SD card health and status:

The detection of the status is not an automatic process. If you want to detect of a different SD card types; this may cause performance degradation and unneccessary wear. To avoid this problem, the program needs to first detect the device type then it will automatically detect the complete status every time. This is simply done using Control device-specific detection to select the type of the device and enable the status detection of the SD card

Now, let’s as an important question:  Do you need Hard Disk Sentinel?

If you are using a computer equipped with at least one hard disk or solid state disk and you want to ensure that your data will be available any time, then the answer is YES. Hard Disk Sentinel is especially designed to you if:

You are using multiple hard disks / SSDs / hybrid drives (SSHD) in your computer (IDE / Serial ATA (S-ATA, e-SATA) / NVMe / SCSI / SAS / USB hard disks) or in an external enclosure (check the hardware compatibility pages for the list of compatible hardware)
You are using a mobile / removable rack or enclosure with hard disk inside
You are using notebook computer
You are using server or desktop computers with high disk load
You want to maximize system stability, HDD performance and overall integrity, receive HDD alert on high temperature or low health
You do not want to lose your sensitive and valuable data, do not want to pay for HDD recovery


Hard Disk Sentinel 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.
Thanks for the very good review, Tarek. The portable version is perfect.
