Yesterday i was installing a new Apple software update for my Macbook Pro.
This required that the laptop be restarted at the end of the download. Tonight when I came home I discovered that my Western Digital will not power on and the blue light will also not come on. I checked power adapter and the firewire cables. All are connected securely. I re-booted the laptop but still nothing. How do I now power the Western Digital back on, or at the very least retrieve all my data. Please help. Thank you very much.

The '?' is due to the computer being unable to find a hard drive.
The most common reason is a hard drive failure, but could also be a SATA hard drive cable fault.
A replacement of the hard drive is required and then a re-install of the OS
You will need some install disks to even begin working on your issue.
Find someone with the same model MacBook Pro and borrow the disks.
Buy a copy of Leopard (10.5) or Snow Leopard (10.6) and use them. If you are going to buy a set you might as well update to Snow Leopard (10.6)
Check eBay for install disks but make sure they are for the same model MacBook Pro.
Contact an Apple service center and purchase a replacement set of install disks.
Once you have a install CD, I would recommend backing up your system by making a disk image of the hard drive to an external drive. Then doing a clean install and then using the Migration Assistant to restore your user files to the clean install on your hard drive.
Take the 2 RAM chips out and make sure they are compatible with your computer and make sure the RAM chips are not broke or defective. Re-insert new RAM chips and make sure they are firmly inserted in their bays. Also, install disc 1 of your 2 disc gray set and hold down C key to boot from disc. Then click on tab for install English. Then go to the top of the screen to utilities and click on disk utility. Now on the left side of screen select your hard drive and then at bottom middle of screen select repair disc. Then when that's done select repair hard drive. Now quit the disc and choose restart from hard drive. See if that don't help ya any. Also, could be bad boot sector in which you will have to save all your data and re-install the operating system. If that don't work, then look into getting a new hard drive and then re-install the operating system. Take your computer into the Apple store and have the Apple dorks look into it if your still under warranty, because you just dropped down some serious cash on this machine.
There has been a known issue with the first key (any key) of a Macbook Pro, not responding when typed and Apple appears to have addressed this with this software update for the Macbook and Macbook Pro:
Run the Macbook Pro Software Update v1.1 and the Macbook, Macbook Pro Keyboard Firmware update v 1.0 per this link:
The Western Digital Scorpio Blue 500GB hard drive is formatted for PC, not Mac. The simplest way to get your MacBook to recognize this new drive--and therefore copy the files from your old drive--is to plug it in to a PC and format the drive. I was advised to format with FAT 16, as this would be recognized by my MacBook. Fortunately, the process was not that involved, since the Vista-driven PC found the drivers for the WD Scorpio Blue automatically. Once formatted, I safely removed the drive and plugged it into my MacBook via a USB port using a BYTECC Drive Mate. Magically, it now appeared on my MacBook Desktop and was recognized by the cloning software I was using, SuperDuper. Three hours later, the files on my old hard drive were successfully cloned onto the Scorpio Blue--except now I had an additional 364GB of storage space. Swapping out the old drive and replacing it with the new was not a big deal at all--just make sure you have the right screwdriver for the last task--a Torx #6. Mission accomplished.
You're probably not actually flashing the firmware, but downloading the utility to do so. Follow these steps:
1. Quit all other open applications. Open the MacBook Pro EFI Firmware update which is in your Utilities directory
2. Click Shut Down in the MacBook Pro EFI Firmware Update window and wait for your computer to shut down.
3. Press and hold the power button on your MacBook Pro until the power indicator light flashes repeatedly, then release the power button to begin the update.
A status bar indicates the progress of the update.
Important: Do not interrupt the update.
Your computer restarts automatically when the update is completed and opens the MacBook Pro EFI Firmware Update.
