4kb in Bad sectors on my Hard drive

[Caleb]

Does it matter for my Hard drive if 4kb is in Bad sectors
and does it matter if my hard drive has not much bad sectors?

with one bad sector comes many bad sectors.

It used to be expected that you would have bad sectors and a certain percentage was accepted. Now technology has advanced to the point where you any bad sectors are bad. As vibro correctly put it, once you have one, more will follow. Back up your data and replace it now while you are able to. Don't wait until you have to.
