From time to time my computer (Windows 10) starts working too slowly, and it takes a very long time to turn off.

I am pretty sure that it has something to do with my second HDD. I have the operating system in C:\ but some of the files are stored in D:\ (a second internal disk), and when this happens I can check that the software that uses data from D:\ are the ones that don't respond. Additionaly, I can see in "This PC" that D:\ doesn't appear.

However, when I turn the computer on again everything works perfectly. I don't know if the disk is broken, or if it's a cable connection problem.

I would appreciate very much some ideas of how I can check what is wrong before buying a new HDD if the problem is not fixable.

Thank you!

Update 28/07/2018: These are the results of GSmartControl: enter image description here


Download GSmartControl and run it. Choose second disk and see SMART report attributes, if there are/is red line(s) - it is means HDD going to die. Most live critical attributes are 5, 196, 197. If they are greater than 0, then you need to replace second disk ASAP

  • I have updated the question with a screenshot of the results. The mentioned values are OK, but not others. Anyway, no lines in red. – user1314836 Jul 28 '18 at 13:51
  • SMART attributes looks good, so drive is OK. How this drive is connected to computer, is it external USB drive or connected internally over SATA slot? – Alex Jul 28 '18 at 14:04
  • Internally, over SATA. – user1314836 Jul 28 '18 at 14:26
  • Rarely, but it still a case, SATA connectors get oxidized and loosing contacts. Try to reset it a few times by plugging/un-plugging on the both sides - HDD and motherboard or if you have a spare SATA cable, try to replace it on second HDD – Alex Jul 28 '18 at 14:37
  • If it wouldn't help, let try to find who is in software department is in charge of slowness then. Could you run perfmon.exe /res when such slowness would happened and switch to Disk then sort columns by Write(then Read) and spot process that accessing D drive – Alex Jul 28 '18 at 15:36
