Modern hardware is designed to shut systems down when they reach temperatures that may be damaging to the internal components. To investigate this, we'll use tools that can display CPU temperatures. If the CPU fan is spinning erratically, or you are experiencing random shutdowns, this may be the result of a thermal issue. NVMe drives can't be checked with a SMART Test through the Disks application but the package smartmontools can be used for this. Pay attention to the overall assessment, and to how close the values are working towards the failure point, which is typically 0. The terms "old-age" and "pre-fail" are normal. This test takes a few hours to run and will will give you a large amount of info about the health of the drive.Īll of the values start at 100, and work their way down to 0. To check the hard drive for disk failures, start the program Disks, select the hard drive on the left, then click the icon in the top right, and choose SMART Data and Self-Tests, and then click Start Self-test and choose the Extended test. If memory errors show up, the memory stick should be replaced. If any errors are found, please run it again in single core mode, and let it run overnight to check for any memory errors. Wait at least 20 minutes for the tests to run, or until any errors are shown in red. Right as memtest loads (blue screen), press F2 to enable multi-core mode. You would boot from a USB drive made with the ISO. Memtest86++ also has ISO downloads for personal use. While this will not put all of memory under test, it will make any memory error likely to cause instability if not part of the tested memory or show up clearly with errors in the memtester run But for older versions you can install it manually by using the below command.Memory test can take a number of hours. If I’m not mistaken, you should be able to use this app in Ubuntu 10.04 & 10.10 (including both 11.10 Oneiric Ocelot and 11.04 of course) without having to manually install it. Remember, although SMART technology is there to help you but don’t run it quite frequently as it might unnecessarily put some stress on the HDD and shorten its lifespan. Just choose your test method and follow the on-screen instructions. Things are pretty much automatic from here. By using this window you can actually see a lot of details of the HDD itself such as its Temperature, whether it passed the last SMART test or not and some individual tests related information. This will let you perform three types of S.M.A.R.T tests on your HDD. Now click on it and from the next window choose “Run Self Tests”. Now, to your left under “Local Storage”, choose your HDD and then to your right-side you’ll see a button called “Smart Data”.ĥ. Then you should see a window a bit similar to the first image shown above.Ĥ. Or just open your Terminal window (or press ‘Alt’ + ‘F2’) and put the below command and press the Enter key (both methods should work).ģ. Just press “Windows key” (in Unity desktop) and simply put the below text and click on its icon.Ģ. There are few users available in Ubuntu but Ubuntu actually comes with a disk utility (GUI) of its own that we can use to perform these S.M.A.R.T tests with ease.ġ. Other than letting the HDD to inform us when something bad is about to happen, there are tools that we can use to perform these tests manually to check for the health of the HDD. This “health check” is performed by the HDD itself by using various read & write methods, spin up/down tests etc. On most occasions, it should be able to notify you just before something bad is about to happen (don’t count on it though… taking backups is still the king). S.M.A.R.T (Self-monitoring analysis and reporting) is a fail safe technology that’s built into newer hard disk drives that has the ability to monitor the drive and give feed-back about its health.
