I picked up a new momentus 750xt after my old 500gb momentus that came with the laptop as a secondary drive to the intel x25 ssd that I have as my boot drive. I started getting slowdowns and long load times with that drive so I figured it was a dying hard drive as it was in there for 2 years.
The momentus started to click and chirp the moment I installed it. returned the first one for a new one and the new one was able to run for 2 weeks before exhibiting the same behavior. I got fed up thinking I got two defective hard drives in a row. Now I just bought a WD black 500gb hard drive and it is doing the same thing, I hear clicks and chirps when I start the laptop up and windows loads but then the drive disappears at times. Sometimes it works fine but half the time I have to reboot because it is not loading properly. The drive also shows 99% health so now I'm wondering if the sata connection is causing this. Funny though when I put the x-25 in the other slot it works and loads fine. Anyone come across a similar situation? I'd hate to RMA this and I don't think I still have warranty left from 2010. I'm wondering if I could just buy a sata controller and put that in to see if that works.
