Mark bad sectors on a drive, and continue using?

Hi guys,

I'm trying to learn more about hard drive repair, recovery, etc.

I use a program called HD Tune to do a full scan of a drive to see if it has any bad sectors. These drives are still readable in Windows, and can be used.

I'm not saying they are totally reliable for use, but just for the sake of curiosity: Is there a way to mark the bad sectors on the drive as unusable, so that if I kept using the drive for basic storage, it would skip the bad sectors automatically, or is this impractical?

If I recall, SpinRite can achieve this but takes quite a bit of time to do so.
