HD Sentinel Multi-OS SSD and HDD Monitoring and Analysis Software

HD Sentinel from Heartfelt Development Services Hungary Kft. is a multi-OS SSD and HDD monitoring and analysis software.

Its goal is to find, test, diagnose and repair HDD drive problems, report and display SSD and HDD health, performance degradations and failures.

HDD Sentinel gives textual description, tips and displays/reports the comprehensive information about the HDDs and SSD inside the computer and in external enclosures (USB HDDs/e-SATA HDDs). Many different alerts and report options are available to ensure safety of valuable data.

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

HD Sentinel monitors HDD drive/HDD status including health, temperature and all S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) values for all HDDs. Also it measures the disk transfer speed in real time which can be used as a benchmark or to detect possible HDD failures, performance degradations.

HD Sentinel is a 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 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 failure and malware, or accidental delete.

How does HD Sentinel work?
HD 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, HDD health status may slowly decline, from day to day. The SMART monitoring technology can predict HDD failure by examining the critical values of the HDD. Compared to other software, it detects and reports every disk problem. It is much more sensitive to disk failures and can display better and more detailed information about HDD expected life and the problems found (if any). This is a way to predict failures than the ‘traditional’ method: checking S.M.A.R.T. attribute thresholds and values only.

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

Do I need HD Sentinel?
If you are using a computer equipped with at least one HDD or SSD and you want to ensure that your data will be available any time, then the answer is yes.

It is designed to you if:

You are using multiple HDDs/SSDs/hybrid drives (SSHD) in your computer (IDE/SATA (S-ATA, e-SATA)/NVMe/SCSI/SAS/USB HDDs) 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 HDD 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
