metal sounds in low gear

[Brett_C]

Whenever I am in 2nd or 3rd gear going about 25-30 mph, I hear a slight metallic scraping sound. It is the same sound as if you rest your foot on the clutch while driving. I can get rid of the sound by pressing the clutch down slightly without taking it out of gear. any clues on how to fix this? I figure it is being caused from the cluth not being engaged all the way or not enough. Thnanks
