Bad sectors - replace or not?

[Mixzzz]

My brothers laptop recently failed to boot and windows was not able to fix itself(when it tried to fix itself, it froze and HDD was clicking). So I backed up his files and reinstalled it. After windows installed I ran error scan with HD Tune Pro and it discovered a bad sector. Also health page show a warning and read benchmark had some really big spikes (Note that my dad has 2 of the same HDDs and they didnt have that big spikes...)

 

My brother currently does not want to buy a new HDD as he doesn't have any spare money for now. Is it safe to use this HDD without loosing his data for now? He does backup his important files once in a while though. Also, is there a way for windows to mark the bad sectors and avoid them?

no

if the hdd smart says its bad

its time to backup and replace it
