The test found bad sector in HDD..., and when i am click the repair button it fails..

I got a western digital hard drive from my friend's box. now i'm connected this the 320 gb SATA drive to my system. the i can see the three partition in HDD as F, G, H. the G&H are accessible but the problem with F. When i'm trying to open this it says "windows need to format the drive" and a popup window says it is not accessible. and i'm tried this drive to format.. that also failure.."windows was unable to complete the format".. As a non -expert i dont know what i want to do.. my system running in windows 7..
