Test the drive with the diagnostics first.
If it completes both the short and longer tests but bad sectors are found, there are things you can try, but the likelyhood is more bad sectors will appear in a short time and you will have to get a good drive anyway.
If the drive fails any of the tests anything else is a waste of time, and you need to get a good drive as soon as possible, if you want to be able to copy the maximum data you don't want to lose from the old drive to the new one. Don't copy the whole partition or the whole drive - that will copy the locations of bad sectors on the old drive to the new one and you can't easily get rid of the falsely marked bad sectors without wiping out the partition contents and starting over.
It would help if you could supply the make and model of your brand name system computer or of the mboard of a generic system.
