Question about bad sectors

[Ej-_-]

Hi, may I ask if this is going to be a problem in the future i just got a report about having 8 bad sectors on my external HDD and the Health is now on 87% in HDD Sentinel and HD Tune pro says Current Pending Sector and when I tried "chkdsk g: /f" it shows it has no bad sectors is this going to damage my External HDD in the future?
here are the pictures of the results

You need to run chkdsk g: /f /r to check the hard disk for bad sectors. The /r option means chkdsk will take much to check the hard disk
