The computer in a Macbook Pro 13" (mid '09) Snow Leopard OSX.
Thinking I had a hard drive going bad after it was sticking and taking forever to do anything,I reistalled the OSX. This worked for a short time then the computer shutdown and would not turn on. I bought a new Seagate drive and installed it but the computer could not find the hard drive to install the OSX. I put the old drive back in and it worked so I hooked up the new Seagate drive externally and the computer found it and installed the OSX and ran without a problem. I then installed the new Seagate drive interally into the computer and now it cannot find it.
Any suggestions to what the problem might be?
Thanks
