Hi guys. I bought a macbook pro 15 inch about 3 months ago and i didnt buy apple care because... well.. i dont know why i didnt :/ anyway i got really mad doing work and i smacked the computer where the harddrive is and i think i broke it. the computer starts and shows the apple logo (without the loading thing) and it stays like that for a minute and shows the terminal full screened with the "You need to restart your computer...." message and above that it says this; panic(cpu 0 caller 0xffffff8000648e1b): "Unable to find driver for this platform": \"ACPI"\",\n"@/SourceCache/xnu/xnu-1699.24.8/iokit/kernal/IOPlatformExpert/cpp:1504 Debugger called: <panic> backtrace (CPU 0), Frame : Return Address 0xffffff807957bdd0 : 0xffffff8000220702 0xffffff807957bdd0 : 0xffffff8000648e1b 0xffffff807957bdd0 : 0xffffff80006267dd 0xffffff807957bdd0 : 0xffffff800062700e 0xffffff807957bdd0 : 0xffffff8000627389 0xffffff807957bdd0 : 0xffffff8000625f6f 0xffffff807957bdd0 : 0xffffff8000820057 cant perform kext scan: no kext summary BSD process name corresponding to current thread: unkown Mac os version: note yet set Kernal Version: : Darwin Kernal Version 11.2.0: Tue Aug 9 20:54:08 PDT 2011: root:xnu-1699.24.8~1/release_X86_64 Kernal UUID: 59275DFA-10C0-3083-9E26-F785DFB1A432 System uptime in nanoseconds: 346403932 Im guessing i broke the hard drive? anything would be greatly appreciated. i am obviously going to try and fix this myself.
