Sabot Posted April 25, 2017 Share Posted April 25, 2017 I am brand new to Unraid and Linux. I wish to install a copy of HD Sentinel. What is the easiest method? Quote Link to comment
trurl Posted April 26, 2017 Share Posted April 26, 2017 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 Nothing that really gives you a history of these things, though. If you really want to use HD Sentinel, I think you should be able to unzip it to your flash drive and then follow the instructions given at the website for using it. I have not tried it.

Squid Posted April 26, 2017 Share Posted April 26, 2017 (edited) 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) Download http://www.hdsentinel.com/hdslin/hdsentinel-016-x64.tar.gz, and extract the file and store it on your flash drive. Then from the command prompt, /boot/HDSentinel to run and analyze. BUT, if you ask me, the program is a POS, and smartctl (which unRaid's UI leverages and notifies you about problems with the drives is better.) Consider this drive.

At this point, warranty replacement of the disk is not yet possible, only if the health drops further. Problems occurred between the communication of the disk and the host 51 times. In case of sudden system crash, reboot, blue-screen-of-death, inaccessible file(s)/folder(s), it is recommended to verify data and power cables, connections - and if possible try different cables to prevent further problems. More information: http://www.hdsentinel.com/hard_disk_case_communication_error.php It is recommended to monitor the drive to be notified about any new problems. No actions needed. 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. Edited April 26, 2017 by Squid Quote Link to comment
Sabot Posted April 26, 2017 Author Share Posted April 26, 2017 (edited) Just found the smartctl data. Nice job. I had HD Sentinel, figured I use it on this server. Thank you so much Squid, you have been answering my questions... are you stalking me? Wow, I would have to agree with you. The report is far from what I am used to. I guess I was spoiled using HD Sentinel in Windows... Edited April 26, 2017 by Sabot Quote Link to comment

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. Quote Link to comment

Arcau Posted April 15, 2019 Share Posted April 15, 2019 @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. Attached is the report from unraid. Quote Link to comment
trurl Posted April 15, 2019 Share Posted April 15, 2019 This thread is 2 years old, so I guess I won't accuse you of hijacking another users support thread. It is usually better to start your own thread though. 41 minutes ago, Arcau said: 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. 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. So the idea that you might put in a small disk that you just happen to have and are uncertain about should really be reconsidered. 1 Quote Link to comment
Arcau Posted April 15, 2019 Share Posted April 15, 2019 thanks @trurl all advice is very appreciated as I am new, still new enough to be using the trial version of unraid infact. Thanks! Quote Link to comment
