Check drive health8/19/2023 I found a sidelight on using TRIM on Samsung SSDs under Ubuntu Linux. I looked into smartmontools, and it turns out to be a well-known Linux tool. Problematic or weak sectors were not found and there are no spin up or data transfer errors.Īnd probably a few stats/descriptions like Power on time, Estimated remaining lifetime and Total start/stop count (some of which might depend on exactly which SMART stats are reported by the drive).Īll OSes, supports RAID (some) and is GNU GPL. A quick glance at the HDS Overview tab is way more humanly accessible/understandable, you would probably see for your drive a flat line 100% Health graph and this: I have 2x Samsung SSDs (+ 3x other SSD/HDDs currently in this PC) and only run the Samsung toolkit for (very) occasional checks for firmware updates, nothing else. #183 bad blocks failed – never = perfect, HDS refers to the same # and stats as Runtime Bad Block (Total) = OK. This is absolutely unintelligible to me and samsung’s response to me was that the drive is OK. ID 183, runtime bad blocks, failed – never, worst 100, threshhold 10, PRE-FAILURE. The site seems to be very factual, no spurious claims made about how ‘brand X’ can solve all your issues and improve your PCs performance, it all appears to be based on factual data, most of which is linked to or, where it’s based on the dev’s own hands on drive testing and log collecting/reading (none is sent by default, as far as I recall, it has to be sent via email, so there doesn’t appear to be anything intrusive/anti-privacy installed), it’s onsite as are links to specific driver versions for SATA chipsets that are known and tested to allow I don’t consider the article particularly good, the author appears to have ignored/missed what I consider to be the most important and accurate posts in the linked forum, #18+19: It’s one of the very few pay software that I own and use and I really wouldn’t want to be deprived of it, it just has a little more about it than the alternatives I’ve tested/used. It’s a very useful diagnostic and testing tool, the developer seems to be very helpful and readily accessible, the website is full of useful data and explanations/tips, etc. This ‘blocking’ of TRIM might also block the application of new firmware to avoid, or fix, certain problems that might be specific to that drive/firmware version.ĭisclosure: I do own and frequently use HD Sentinel Professional, as I have done since winning it in an online draw. the chipset driver version (sorry folks, Fsutil cannot detect whether an SSD is actively using TRIM or not – commentards, blogtards and tech ‘journos’ please take note). Some SMART monitoring software goes the extra mile, even really checking whether TRIM is actually active on an SSD, or merely enabled by the host OS but blocked by eg. So, when it comes to software that’s monitoring drive health via SMART, they’re each only as good as the data supplied. SMART is therefore (remember – it’s the drive that’s self-reporting!), of limited use – but when it does detect/report errors – they need to be watched over time and acted on before the inevitable happens. Vendors do not use the same set of reporting stats, they can pick and choose which are enabled by firmware or are limited by the chipset used. There are many times when drives die without ever having logged any SMART errors.ĭrives can die long before expected, or function for much longer, they rarely, if ever, die on the day forecast. Not all drives, even of the same type, HDD, IDE, SATA, SSD, etc., give the same subset of ‘useful’ data, some don’t have temperature sensors, some report on a greater number of ‘useful’ stats than others. Only a specific subset of these #s can be used to judge a drives likely lifespan and health. Vendor-specific data may not be readily available, or correctly interpreted, by some SMART monitoring software. Only a certain subset of the SMART #s are fixed, other #s can be, and often are, vendor-specific.Įven then, some of the fixed #s might need calibration, like the temperature readout, #190. (Self-Monitoring, Analysis and Reporting Technology) is what all these tools get the data from. A few basics on SMART as I understand them:
