More different problems should decrease the result much drastically than only one single problematic attribute. It should count the relationship between attributes. Constantly increasing number of problems should constantly decrease the result. It should reflect small changes and degradations. It should not increase with time – do not show the health status better after some time (except if some pending sectors were successfully tested and they can be used because they have no problems). Determine the result without using long time analysing or testing methods. Should not depend on time or past values.

When developing the calculation method, the following aspects were important:

attributes) are used to determine hard disk health. If this option is selected, the raw, measured numbers (displayed in the Data column for the corresponding S.M.A.R.T. The differences between these evaluation methods:

Open Source software is software with source code that anyone can inspect, modify or enhance.

Freeware products can be used free of charge for both personal and professional (commercial use). The Professional version has scheduled and automatic (on-problem) hard disk backup options to prevent data loss caused by not only failure but by malware or accidental delete also.įreeware programs can be downloaded used free of charge and without any time limitations. This way even a small HDD problem can't be missed.

Hard Disk Sentinel Portable (HDD 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 hard disk health rating system which is extremely sensitive to hard disk problems. 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. (Self-Monitoring, Analysis, and Reporting Technology, built in most hard disks and solid state disks today) values for each disk.

The software monitors hard disk drive / HDD status, including health, temperature and all S.M.A.R.T. Many different alerts and report options are available to ensure the maximum safety of your valuable data. Hard Disk Sentinel Professional Portable gives a 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). 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 Portable (HD Sentinel) is a hard disk monitoring software with support of HDD/SSD drives.
