Hey, First of all I apologize if this ends up being a repeat, after browsing around threads looking for a solution I resorted to creating an account to try and get some help, and therefore am unfamiliar with the running of the site. I also just got back to school and don't have a whole lot of time to get my mac running again. So, the issue: Recently my macbook pro (bought last summer so mid 2010) dropped about 2-3 feet onto a tile floor. It was in class, and the screen was shut, so I picked it up and opened it, it was working fine. I had no problems with it and used it the rest of the day until the battery ran out, and left it to charge over night. The next morning it would not start up properly and I could only get it going in safe mode. I took it in to see a "genius" and after trying a few things he concluded my hard drive was dying, and I would need a new one. After he returned my mac I went home to attempt to boot into safe mode and back up what files I could, and I got the flashing question mark folder on boot up. I tried what I could but figured the drive had died so I went and got a new Western Digital 320GB 7200 RPM drive, and swapped it in. Now I just tried to boot it up using the original OS dvd and I am getting the same flashing question mark folder. I tried the hold option / c / reset PRAM but still the same thing. Should I be taking other steps to install since it is a clean new drive, or are there other problems going on? Thanks in advance for any advice.
