Drive has 8 bad sectors - do I need to worry?


#1

Well, so here’s the thing:

  • For quite a few weeks, my laptop started running slow unexpectedly. No new driver or windows updates installed, no new applications installed, nothing. When I’d boot up, just like a sequence, explorer would crash, launch taskmgr, and then restart explorer.
  • So I decided to check for driver updates, windows updates and as expected everything was up-to-date
  • I somehow doubted there was some issue with the disk and randomly launched Crystaldiskinfo and it showed caution, indicating a pending reallocated sector count of 1. That’s not a thing to be too afraid of, as that will be nullified when it’s overwritten, but that’s not the thing and I don’t have great belief in SMART, as the HDD manufacturer simply uses different ways to hide away the reality of the HDD. So yeah, I ran a chkdsk and it reported that everything was fine. That’s kinda obvious because the OS contacts the HDD and the HDD simply hides away the bad sectors.
  • So let’s do some deep digging. I ran HD Tune and AOMEI disk checks and they detected 8 bad sectors, but that’s not a big deal, is it?
  • Then the thing I ran a while ago was a DST check (extensive and short) from the UEFI Diagnostics and yeah, there’s the error detected, as both the tests failed!
  • I also ran a DLDIAG test and all it throws at me are bad sectors that cannot be corrected. The funny thing is that SMART doesn’t even have a clue about what’s going on, rendering it an useless component

Here are a few screenshots that may make the issue clearer:

So what’s the resolution now?

Hi Sayan,

You can refer the below mentioned link to check for the detailed information about the Test Error Code and proceed further with the required steps.

Backup your data and transfer to another drive.

Use badblock read&write tool for check if these sectors can be repaired or not.
But 1/2 bad blocks is fine more I stop using my drive often continue to grow :frowning:

I have checked that. The sectors are not repairable. Looks like it’s time for me to get a new drive. I have backed up any way
