Crystal Disk Info "Caution" : C5 Number of Unstable Sectors: 1

Solved
chibimaya92 -  
Hello,
I used Crystal Disk Info on an external 4TB hard drive that I own, but the issue is that I saw the indication "Caution": C5 Number of unstable sectors: 1

I tried to defragment my hard drive and run chkdsk, but it found nothing

Do you have a solution, please? It bothers me to lose a 4TB hard drive.

    Hello
    your external HDD can last for many years (all my backup drives are old system drives)
    the read/write frequency is much less aggressive, the R/W phases are often separated
    neither defragmentation nor file system test and repair can fix a HDD

      I see, I will look into separating the sector, especially since there is only one.

    Hello
    the safest option is to replace your disk
    the defective sectors are irreparable
