I've not used this but looking at its web page, I think some of the functionality is builtin to unRAID already. unRAID monitors disk temperatures, SMART, does short and long SMART test. Performance testing here
TLDL: Its a commericial piece of software attempting (and failing) to analyze the output from the free software already included in unRaid... (BTW, the linux version is not what you're used to in running the Windows version)
HDSentinel makes a big argument on their website about how the manufacturers set the thresholds such that they cannot be hit, and how their method of analysis is far better, and yet according to smartctl which is reading the threshholds set by Seagate, and reporting the values, and the drive itself says that it is in a failing state, and yet HDSentinel states Yeah, there's no problem, don't worry about it....
By the way, the end to end error that HDSentinel is saying "12 errors occured during transfer" is one way of putting it, albeit the wrong way. The proper way of putting it is that there was a communication error between the drive head and the sata interface on the drive (ie: an actual physical failure), which is why Seagate sets a single failure as "FAILING NOW"...
Outside of this rather large error on their analysis, it is interesting in that it attempts to put into english what is shown on the drive's SMART reports. BTW, you can RMA a drive before any attribute is in failing status.
You can get that from command line as Squid did, but we usually just click on the disk in the webUI to look at its Attributes. You can of course see the temps in the webUI also, and you can even run short and extended SMART tests all from the webUI.
@Squid So I am still pretty new to all this, and don't understand where it says pre-fail and old age are they just "normal states" for all drives regardless if its a new or old drive as long as they are working?
I have a 1TB drive I got with some gear and don't want to use it if I just have to replace it in a month or so. Thats what lead me to this thread and the look into HDsentinel for the expected life left portion of the report.
Just throwing another disk into the array for no particular reason is not really a good idea. I recommend not using any more disks than needed for capacity and add others as needed. Fewer disks means fewer opportunities for problems.
And I don't recommend using old or small disks. Larger disks are more cost effective in several ways. You get more storage per dollar. A large disk gets you the same amount of storage as several smaller disks and only uses one port. And larger disks typically perform better than smaller disks due to increased density. And as mentioned in the previous paragraph, fewer disks means fewer opportunities for problems.
And you should never use any disk of any size unless you trust it. Parity by itself cannot recover anything. ALL bits of parity PLUS ALL bits of ALL other disks must be reliably read in order to reliably reconstruct a disk.
Hard Disk Sentinel (HDSentinel) is a multi-OS SSD and HDD monitoring and analysis software. 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/reports the most comprehensive information about the hard disks and solid state disks inside the computer and in external enclosures (USB hard disks / e-SATA hard disks). Many different alerts and report options are available to ensure maximum safety of your valuable data.
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. See the How to: monitor Network Attached Storage (NAS) status for information about hard disk monitoring in Network Attached Storage (NAS) devices.
Hard Disk Sentinel monitors hard disk drive / HDD status including health, temperature and all S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) values for all hard 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. How to check hard drive health
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.
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
Hard Disk Sentinel (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.

Both Hard Disk Sentinel and Hard Disk Sentinel Professional can be downloaded for trial purposes but in these unregistered versions some functions are not available. The Trial version available on this page is the same as the unregistered version of Hard Disk Sentinel Professional.
Hard Disk Sentinel was founded and first released in 2005, developed by Heartfelt Development Services, based in Urhida, Hungary, with Jnos Mth as the company's CEO. The first version of Hard Disk Sentinel for Windows released on 1 November 2005.[7][8][9][10][11][12]
In 2007, version 2.00 released with supporting USB drives along with free trial (unregistered) version, Hard Disk Sentinel standard (paid version with basic disk monitoring) and Hard Disk Sentinel Professional (paid version with alerts, detailed reports, tests).[13][14] Since 2009, with version 3.00, Hard Disk Sentinel supports numerous RAID controllers, by detection of hard disk status in RAID configurations and disk surface testing.[15][16][17]
Version 6.10 included a more graphic interface on par with Windows 11 as well as supports quick disk repairing, additional warnings and statuses display. This version focused on some changes in favour of detecting more problems before they are able to cause data loss.[25][26][27][28]
The software is designed to find, test, diagnose and repair hard disk drives, reveal problems, display health and avoid failures by using S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) function of hard disk drives.[29][30][31] The detected information can be saved to file in formats such as HTML, text, or XML.[32][33][34]
Hard Disk Sentinel has the capability to function for both internal hard disks and external hard disks as well as hybrid disk drives (SSHD),[35] SSDs,[36][37] NAS[31] and RAID arrays within the same software.[38][39][40]
