Hi, So i bought this hard drive right after christmas. The drive works and i have 400+GB left on it but maybe once a week it will make a clicking noise and then the drive will stop working. I have to unplug it and plug it back in and it will start working again. I did have it plugged into a long cable but after reading it may not get enough power that way i then used the cable that came with it but the problem still continues. The wd site says the next thing would be to get a power booster cable? Is there a way i can test if the hard drive is getting enough power or if the drive has issues?
