Freeze related to hard drive?
Hi.
I have an 15'' Macbook Pro Late 2011.
I am having this freezing issue since I got it. I run it with Snow Leopard, Lion, Mountain Lion and there is no change in status, still having freezes.
Had the Apple Hardware Test like 10 times but no clue about issue.
Now.
I am having a hard disk related issue for the 3rd time. First my hard disk was crashed and didn't even see the boot screen. Then I had the same again. Yesterday I had this issue that in the boot screen -gray Apple screen with the loading thing- it was stucked forever. Luckily I had another partition on my disk so I installed ML on it to boot. First I was able to see my broken partition. But after a restart it was gone. In disk utility it was unmounted. I tried to mount it back, but no response.
So, do you think all freezing and these issues can be a hard drive related thing? Is there a way to check it?
And I am suspected from the GPU too because I am always having these broken (pixelated) areas in Safari and etc.
Sorry about my English. I am so wasted right now.
MacBook Pro, Mac OS X (10.6.8)
