Hard Disk Drive (HDD) or Solid State Drive (SSD) is the main storage unit of a Computer. When a data is copied to a HDD/SSD it is stored to tiny areas in its surface. So, even a minute damage or dirt in that area can render that data unreadable. By default, HDD/SSD marks such area/sector as bad, tries to read and copy the data (reallocate) to a spare area first and then redirects all access to that bad sector to the spare area. As such that bad sector cannot be accessed even by a complete drive format. While it may sound good since this process doesn’t require user action, for drives with constantly increasing bad sectors, it can cause serious trouble because the user gets ultimately notified when very little spare area is left for reallocation and a very little time (about 24 hours) to backup the data. Moreover, problems resulting from Weak sectors, High temperature, Incorrect power, Mechanical shock, Vibration are not necessarily notified by the HDD/SSD.

Hard Disk Sentinel, in contrary runs in background and monitors the status and health of HDD/SSD by constantly monitoring the S.M.A.R.T. status of the drive(s), not by just checking S.M.A.R.T. attribute thresholds and values like most similar software and reports about even slightest errors/failures as soon it is detected.

Tests in Hard Disk Sentinel
Hard Disk Sentinel offers an wide variety of tests that can verify and fix problems in HDD/SSD under a controlled environment.

Hardware Self Tests

The hardware self tests built in IDE and Serial ATA hard disks are the perfect solution to test the hard disk status quickly or with very high detail.

• The Short self test verifies the major components of the hard disk (read/write heads, servo, electronics, internal memory, etc). This test takes only some minutes.

• The Extended self test performs the above and it has a complete surface scan which reveals the problematic areas (if any) and forces the bad sector reallocation. It is recommended to periodically use this test to verify the disk health – especially on a hard disk with less than 100% health.

Random Seek Test
By this test it is possible to verify the noise level, track-to-track seek time and temperature levels of the hard disk, especially under excessive disk usage.

Surface Test
By using this test, the surface of the hard disk can be examined with different methods.

• READ Test – Reads the disk surface to verify if all sectors are accessible and readable.
• WRITE test – Overwrites the disk surface with configurable pattern. Forces the analysis of any weak sectors and verifies any hidden problems and fixes them by reallocation of bad sectors (this is drive regeneration).
• WRITE + read test – Overwrites the disk surface with configurable pattern and then reads back sector contents, to verify if they are accessible and consistent. Forces the analysis of any weak sectors and verifies any hidden problems and fixes them by reallocation of bad sectors (this is drive regeneration).
• Read + WRITE + read test (refresh data area) – Reads stored data from each blocks, writes back the contents and finally reads the information and compare with original contents. By the extensive test, an additional write cycle is used before writing back the contents to improve the efficiency of the error correction (drive regeneration).
• Reinitialize disk surface – Overwrites the disk surface with special initialization pattern to restore the sectors to default (empty) status and reads back sector contents, to verify if they are accessible and consistent. Forces the analysis of any weak sectors and verifies any hidden problems and fixes them by reallocation of bad sectors (this is drive regeneration).

Reports

• HD Sentinel can be configured to send e-mail message if a failure predicted, if a hard disk is too hot or if a critical S..M.A.R.T. parameter is degraded. Also it can be used to send daily reports about the current status of hard disks.
• The user can also send test reports to developer for further help in analyzing the situation. Even in offline PC it is possible by creating the report, saving it and then sending it via a PC with internet connections.

Sound Alert

HD Sentinel can ring sound alerts on any incidence that needs user to take action. By default, sound alert is not enabled.

Automatic or Scheduled Projects
With HD Sentinel Professional various projects can be defined, that can be scheduled to execute regularly or in case of some events, for example if a decrement in HDD/SSD health is observed. It is also possible to execute two or more different projects at the same time or sequentially (run a project after the the other project is completed). The type of the project can be:

Run external application or batch file: the project will start the specified external application, internal command (for example COPY) or batch (BAT) file.

Transfer files and folders: this case the internal archiver module is used to backup files. By using this module, it is possible to configure different archiving options and create different, specific backup tasks.

Burn CD/DVD by using NERO: Hard Disk Sentinel will use NERO (TM) application from Ahead Software AG to archive the contents of any specified folder to an optical disk.

Compress files by using RAR/7-Zip: Hard Disk Sentinel can use WINRAR (TM) application from RarSoft or the free 7-Zip application as compressor.

Export registry items: the specified registry keys will be exported into a file.

Power ON Computer: Power on (start) a remote computer on local area network by sending wake-up packet to the target computer.

Power OFF Computer: Local or remote computer can be stopped (shut down) or restarted (reboot). The local computer can be sent to standby or hibernate states also.

Send files in e-mail: By this function, files (or complete folders with all files and sub-folders) can be transferred in e-mails.

FTP Transfer Files: By this option it is possible to upload files or complete folders to FTP server.

Test hard disk(s): It is possible to examine and test the hard disks by using hardware self test functions (supported by IDE and S-ATA hard disks). The disks to be tested are listed and can be selected, or it is possible to test all installed hard disks simultaneously.

Password Protection

The software allows password protection for unauthorized usage of the software and its configuration.

HD Sentinel can be controlled remotely.

• If WebStatus is enabled, it is possible to examine hard disk status from the local or a remote computer/mobile phone/PDA by using a web browser. Optionally a password can be used to prevent unauthorized access.
• Hard Disk Sentinel can Accept remote connections from server and this way it can be used to remotely analyze hard disk problems, verify hard disk status and test hard disks.
• It can use DynDNS, No-IP or Custom Dyamic DNS service to assign a fix host name to a changing (dynamic) IP address of a computer. With this constant host name, the computer could be accessed remotely, so remote management (webstatus, remote connections) is possible.

Hard Disk Sentinel can work either as an Application or as a Service. By default, it runs in Application mode and the software launches when an user, with proper administrator rights, logs in. When running Hard Disk Sentinel as a Service, it starts with theOS  and runs even if no user is logged in or if a user has only limited rights.

Hot Keys are supported to access some functions of Hard Disk Sentinel.

The software can automatically check for updates (weekly). This is not enabled by default. Manual update check is also available. In case a new version is detected, it downloads and installs it after requiring permission from the user.

The same configuration of the software can be used on multiple PC by backing up the configuration from one PC and restoring it in another PC.

The software allows you to check the available warranty period of a hard disk. The user will get recommendation about the ‘warranty replacement’ once the health of the HDD/SSD is very poor (0%).

HD Sentinel documents all essential information on the working principle of the software and the basics of HDD/SSD monitoring in the offline help file and in the online help, FAQ and Knowledge-base.

System Impact of HD Sentinel is low.

Hard Disk Sentinel Professional System Impact

Hard Disk Sentinel has the following requirements in a PC.

If you have followed my previous blog posts, you must have noticed that my way of writing about this software is different as if I have given more effort to emphasize on all of its features. This is simply because the software is awesome and I am highly indebted to it and its developer. When I contacted Janos about Hard Disk Sentinel Professional, my view about the software was like other hard disk monitoring software. Even after trying the software for about 2 weeks my view didn’t differ much truely because I wasn’t able to understand fully about all its components. But last week, while I was about to write my review on this software based on its feature set, I experienced a serious problem with my external hard disk that contains many important data of my phD program as well a huge number of downloaded journals. Hard Disk Sentinel showed that my hard disk has a very low health of 9% (see the 2nd and 3rd screenshot). To check if Hard Disk Sentinel gives wrong information about external hard disk I checked another external hard disk and it was 100% healthy.

I also cross checked the situation with two other software that were supposed to do the same thing. Unfortunately I was not able to get any satisfactory information from those software. That point was the beginning of my understanding of Hard Disk Sentinel Professional in more detail. I contacted Janos about the problem and he guided me with detailed instructions and explanations for troubleshooting the issue. After a lengthy procedure of backing up data and carrying out hard disk tests that took about 6 days to complete, my understanding about the uniqueness of the software was almost clear. Hard Disk Sentinel Professional was also able to detect problems in the HDD (see 8th screenshot) of my PC. I was aware of the faulty hard disk cables in my PC but did not expect that it will be detected by a HDD monitoring software mainly because the aforementioned software was not able to detect this problem too.

I had a few wishlists about the software that I already conveyed to the developer.

Lifetime version of Hard Disk Sentinel Professional is worth $35. The developer of Hard Disk Sentinel Janos Mathe has generously arranged 25 lifetime licenses of Hard Disk Sentinel Professional for our blog readers.
