Recently my MacBook's HD stopped working I just couldn't boot into it! It was really strange so I tried starting it up with my Leopard disc and it just spat it out after it spinning around for a while, creating quite a racket. It says the HD is not mounted so I took it out and put it back in multiple times and it still didn't work. So I'm wondering if both my HD and my ComboDrive are both broken...The HD is one I installed myself, it's a 250GB Samsung HM250JI partitioned at 232.9GB. I've had problems with Samsung drives in the past with a 160GB Samsung HD, and that broke also. These HD problems also always seen to happen once I install Windows on my MacBook, before that it would work fine, and once I install Windows it just goes to Hell. Any suggestions? Also would it be possible for the people at my Apple Service Center to switch my ComboDrive to a SuperDrive. Also my ethernet plug doesn't work and my MacBook makes quite a loud grinding sound. Here's a screenshot of what Disk Utility says at just the regular analysis of the drive. And here's one of it after attempting to repair it.
