Windows – Hard Drive suddenly became unresponsive, recovered on reboot. What to do next

hard drivehard-drive-failurewindowswindows 10

So I have a desktop PC with an SSD and an HDD. Windows 10 is installed on the SSD, all my data is on the HDD. Today while I was playing a game, it suddenly became unresponsive. At the same time, the video I was watching on my second monitor froze as well. The game is installed on the hard drive, the video file was on that hard drive as well. Both programs became unresponsive, while all other programs that are installed on the SSD continued to run fine. After about 2 minutes, the game crashed and the window disappeared, along with VLC player (which was playing the video file). I checked the Explorer, and the E: and D: partitions on that hard drive didn't show up anymore.

So I rebooted and the drive shows up again. . I ran CHKDSK on the drive, which ran fine and returned no errors or bad sectors (CMD output below). I also installed SeaTools and ran a couple of the simple tests on the drive, all of which ran fine and didn't show any error.

So now I'm not sure what to do. All my data is continuously backed up, so if the drive crashed and didn't come back, I wouldn't lose much. Since the SSD doesn't seem to be affected, I could probably just install a new hard drive without even having to reinstall Windows. But of course I don't want to throw away a perfectly good 2 TB hard drive, and since everything seems to be fine …

What could have caused this problem? How likely is it that it was a software defect rather than a hardware problem? I noticed earlier that the video froze a couple of times, but I was copying some files and downloading some other stuff, so that's not that unusual … are there any other diagnostics I can perform to see if there's a problem with the hard drive? Any suggestions are welcome. Thanks!

If the disk only crashed once and now everything is OK, then this event was maybe exceptional.

My own guess is that the hardware overheated because you were using a lot the GPU and/or the CPU.

What you can do to check the problem :

• Look for a useful error or warning in the Event Viewer
• Install a product that can show the disk S.M.A.R.T. data and tell you if there is a problem (example Speccy).
• Install a temperature-monitoring product such as Speedfan which can be configured to display the current temperatures in the taskbar for easy monitoring.

If heating up is the problem, you may :

• Verify that the game uses the video GPU and not the CPU
• Clean up all airways
• If a laptop, place it at an angle, so the air can pass below it, or buy a cooling pad
• Renew the CPU thermal paste and heat sink (better done by a professional)
• Replace the CPU heat sink and fan with a better one (also better done by a professional)
