I have a brand new 13" MBP. It came with a 250GB HDD. I bought an OEM 1TB Western Digital Scorpio Blue internal HDD. It fits perfectly, even though some have complained because it's taller than most 2.5" drives. Here's the link: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136545&Tpk=wd 1tb Anywho. I installed it, and all seemed great. I booted it up, and as expected saw the folder with a question mark because there was no OS installed. No problem. I insert my Snow Leopard disk, and it looks like it's loading the install files (twisty status thing underneath the Apple logo). No problem. HOWEVER: It takes longer than usual to "load" these files, and I never see the OSX install dialogue. Instead, it stays on the grey screen for an extended period and then I get the grey screen of death telling me to power down. I called Apple and they said to call Western Digital. I called them, got disconnected and frustrated, and just haven't called back yet. Any ideas?
