A monthly anti-malware full scan was run on this pc using Windows Defender (-aka- Windows Security) as routine, but not this month.

Will running a full scan from Windows Defender adversely affect the failing hard disc?

Caution status - CrystalDiskInfo

Popup when hovering over the health status reveals -

  • Reallocated sector count: 2216
  • Current pending sector count: 08
  • Uncorrectable sector count: 08

Additional Information that may or may not be relevant -

  • PC is a lenovo laptop, 3+ years old
  • Mild usage, 2-3 hours a day, browsing, streaming YouTube and Netflix and such
  • It doesn't have any other problems - no malware, no performance issues
  • No errors or other warning signs except Action centre doesn't work for some reason, but is likely not related to this
  • I was doing a new year cleanup on the pc, noticed that I hadn't run crytaldiskinfo in forever and discovered the "Caution" health status of the hard disc

On a failing drive you should make certain every read, every interaction works towards the goal of securing, saving the data. Every read is precious and should be treated as if it were the last.

A virus scan is a waste of whatever life the disk has left.

If this were my disk, I'd backup data ASAP and replace it ASAP. It has been reallocating sectors before and there are more pending. I'd treat it as a terminally ill drive and use a tool designed to deal with those such as ddrescue or HHDSuperClone.

People may argue this is 'normal' as "no normalized thresholds were crossed" and after all "this is what spare sector pool is for", I am not one of those people.

I am one of the people you may turn to when a drive all of a sudden craps out and you tell to that the warning signs were there, you noticed them but ignored them.

I am one of the people who'd argue 2216 reallocated sectors and more on the way is not normal for a healthy drive, regardless what normalized values are telling and whether thresholds are exceeded or not.

A failing disk should first be used to backup any data for which you have no backups. It should not be used for anything else before that, to avoid its finally dying and taking the data with it.

After the data is safe, you may do anything that you like with the disk. As long as you take care that its final failure will not cause you any problem.

Usually formatting the disk with a slow (not quick) format might make it usable for some time, as long as you keep watching its SMART attributes. If the number of bad sectors continues to increase, the disk is finished.
