WD3200AAJS is dead

After Five Months my Western digital WD3200AAJS  320Gb HD has dead

Is there a chance to be repaired ? I replaced the tvs diode but not work does shortening it works? Or other components tried? How to check if head & media is OK. I have also a 160 Gb Seagate HD IDE and has 6 years of intense working, and this WD lasted only five months.

Hi there, is the drive not seen anywhere at all on your computer? What have you tried so far? o.o
