WD MyBookLive 2T does not boot up

Hi guys from few days my MyBookLive power up, ays few seconds with LED blue, HD is working (it seems to read) but LED switch to Yellow and it stays without actions. After few minutes, HD restarts to work (3/5 second) and stops … I already trid to perform reset by push button on the back and power off/on it. Have you got any suggestion to access to my HD? Thanks is advance to everybody!
