Hello. Here is my problem. Its a weird problem really. One day I powered my Macbook and I was getting a folder with a question mark. I opened the bottom case and checked. Everything seemed fine. I disconnected the hdd and I tested it on another computer. The HDD seemed 100% fine. But for some reason my Macbook wouldn't see the operating system. I disconnected again and formatted and connected again. But it would take forever to boot the Snow Leopard DvD. After booting it wouldn't see the hard drive. After I remove the RAM and power up again and I boot my Windows dvd. It sees the hard drive and I was able to install Windows perfect. I go to sleep and in the morning again it shows the folder with the question mark. Of course I tried another 2 hard drives and another Ram. Everything I tried came up with the same problem. 1 in 10 times it would find the hard drive. Every time it found the hard drive I wasn't able to unmount it through disk utility in Snow Leopard Setup. At one time it wouldn't find the hard drive for 50 consecutive times. Then I load Ubuntu Live cd and I could see the hard drive perfect! I restart and it would say "Disk error blah blah blah", an error from my Windows Installation. I try again Ubuntu Live cd and again I can see the hard drive. I try to install ubuntu but I get an error while formatting. Any suggestion would be perfect. I think it might be the hard drive cable that's causing all the problems. That's what I have tried so far :
1. Resetting the NVRam.
2. Tried 3 Hard Drives. All same problem.
3. Tried 3 different Ram. All same problem.
4. Tried installing Ubuntu in the external hard drive and then placing inside the Macbook. Wouldn't boot
5. Tried repairing Hard Drive through Snow Leopard when I could see it. Wouldn't repair, it gave an error.
