You can tell if your hard drive for your Macbook Pro has really crashed, if you attempt to run these 3 diagnose and repair procedures and there is no response from the hard drive:
1st Procedure:
font.f1 {font: 12.0px Helvetica}
font.f2 {font: 14.0px Myriad Pro}
- USING FSCK COMMAND TO VERIFY AND REPAIR DISK-
Start up your computer in Single-User Mode to reach the command line by doing this:
•Make sure your Mac is shutdown.
• Reboot your Mac
• When Mac
starts up, press the Apple Command key+ S Key
- A black screen, with white text appears
• At the command-line prompt, type /sbin/fsck -fy
• Press Return.
--fsck will run through a series of tests and will return information about your disk's use and fragmentation. When completed, it will display this message if no issue is found:
The volume (name_of_your_Mac_volume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message: --FILE SYSTEM WAS MODIFIED--
Important: If this message appears, repeat the fsck command you typed at the beginning, until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
• When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
• This last command after completing the fsck process, is going to attempt to boot your Mac to the main desktop.
If unable to reach your Desktop with the fsck procedure, go to the next step.

Procedure # 2
font.f1 {font: 13.0px Myriad Pro}
-RUN DISK UTILITY WITH STARTUP DISK-
Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the startup disk to the Installer environment
• From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utilities run this repair the disk until completion
• At the end of this process, reboot your Mac
* If you have still not gotten a successful boot to your main desktop, try this final step.
----------------------------------------------------------------------
Procedure # 3
My recommendation for this issue, is that you use the Archive and Install procedure to resolve this issue.
What this process consists of (using your Mac OS X install disc),is removing the damaged or corrupted Mac OS X directory and replacing it with a brand new directory.
This procedure also allows you to save your applications, files and folders without the old directory interferring with you then accessing those files.
-ARCHIVE AND INSTALL-
• Start up from your Mac OS X Install Disc 1 or Install DVD. Please remember to use the install disc that matches the current operating system your system haves.
Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key.
• Hold the C key until you see a White screen, with a Gray Apple icon and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
-Your mac will now boot from the disc and load into the Installer environment.
• Select your language. The Welcome to the Mac OS X Installer window appears.
• Click Continue. The Important Information window appears.
• Follow the prompts until you get to the licensing agreement screen
• An agreement sheet appears. If you agree with
the license agreement, click Agree. Then Select a
Destination window appears.
• Click the volume that you wish to install to (your primary hard drive).
• Click Options. The installation options sheet appears.
• Select Archive and Install.
• Select the volume which already has Mac OS X installed.
• You should also select Preserve Users and Network Settings, to preserve network and Home directory settings.
• Click OK.
• Click Continue to begin the installation.
• Once the Archive and Install is completed, when you reach your desktop be sure to run all Software updates to bring your new Mac OS X directory back
up to current.
Also, if you look inside your Macintosh HD icon on your Desktop, look for a folder entitled "Previous System Folder" which will have all of your previous Home folder files prior to the Archive and Install.
Here is the link (below) from Apple for more information about how to locate the Previous System Folder
How to locate
Previous System Folder (after Archive and Install)
----------------------------------------------------------------------
If there is still no responsiveness of the hard drive after this last procedure, your best option would be to take your Macbook Pro in for repair or replacement of the hard drive, to your local Apple retail store Genius bar or local Apple authorized service center.
