    Smart diagnostics can be done with drive manufacturer's utilities, or a number of third-party utilities, such as hddscan for windows. Some major brand oem systems (such as dell, hp) have diagnostics baked into the motherboard firmware that can do these tests as part of its overall diagnostics test suite. - Source: Reddit / about 2 months ago
  • What is wrong with my PC?
    I don't remember for sure what software I used but I think it was HDDscan. My device was a 1TB hdd. Before even scanning I noticed it was constantly at 100% utilizarion in task manager and simple things like opening a browser or file could take up to 10 minutes. If you have an ssd I couldn't say too much about those going bad. I only dealt with a bad ssd once at work. In that case the oc would not even boot. - Source: Reddit / 3 months ago

  • Black Screen After Closing Laptop Lid
    Troubleshooting these seemingly random things can be a pain, so I would start ruling out the more direct tests, first going to the official website for your laptop model and checking the support/downloads page to make sure you have their latest drivers and BIOS running.

  • Blue Screen on all games - but not on benchmarks
    There are disk health checking tools that you could use, most of them tend to record issues into the SMART table, or you could run a surface test. For example HDDScan is a small, free tool, you can try the SMART check first and if that fails run a surface test (do NOT use the data wiping tool with the red icon). - Source: Reddit / 5 months ago

  • I bought an 18TB refurbished external hard drive on a whim from Amazon. What kind of testing should I do when it arrives?

  • This SSD I/O issue makes me feel like I don't belong in IT anymore
    I got a hold of Hiren's Boot CD ISO which when booted provides a WinPE loaded with different tools and diagnostic software and I ran a tool called HDScan and I run the Erase test - this test starts off fine, with all blocks written without much latency, and then hits blocks with 500ms+ delays. - Source: Reddit / 10 months ago

    Stress test however you want to. I'm more familiar with Windows. I use Hard Disk Sentinel ( and/or HDD Scan ( Usually a good full disk write test followed by a full surface scan suffices.
