When the hard drive starts up, you can hear the disks spinning and the device working. However, now when I power on the hard drive I get nothing. The blue light comes on and I can sometimes hear the device clicking as it tries to start spinning, but it never gets going. My computer recognizes the power on and power off, but it cannot detect the hard drive b/c the drive never gets going. Any advice on how to correct this problem? I have everything stored on this drive.

Re: the hard drive won't boot up
The hard drive is dead ( dreaded click of ***** syndrome )
you can have that verified at a computer repair shop and if that is the case use a solid state hard drive as a replacement and not the spinning disc type as for the data you have stored , there are places than can recover it from the dead hard drive but unless you have it all backed up on an external hard drive or storage device then it is lost
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Have you left a CD in the CD Drive, if so take it out and re-boot. Can you access the BIOS - if so check the Boot Order and ensure the Hard Disk is the first boot device. Also check that the BIOS is recognising the Hard Disk. It maybe that the Hard Disk has gone down - can you hear it spinning up or down when you boot up or switch off. Make sure it is seated correctly.
Can you hear any fan or drive sounds? If you don't hear anything at all when you try to turn the laptop on, no little LED's light up, the problem almost certainly isn't related to the hard drive. So if you don't have a live screen, start with the LCD troubleshooting flowchart, and if you don't have any activity at all, start with the power troubleshooting flowchart. Even if the hard drive has failed at the electro/mechanical level and won't spin up, this wont prevent the LED's on the laptop from lighting up, or the LCD from displaying the BIOS information and complaining about the lack of a boot device.
There are a few procedures you can possibly try before replacing components.
I HIGHLY recommend you unplug power while trying these steps
1) Unplug power and remove CMOS battery (usually a small silver circular battery) on motherboard for 1 minuted then reinstall battery and see if it boots up.
2) Re-seat all RAM memory chips. If it doesn't help, then try booting the system 1 memory chip at a time, to rule out a bad stick of RAM
3) If you have a separate video card (not onboard video) then try re-seating it
4) unplug both data and power cables to all internal components (hard drives, CD-Roms, Floppies, etc) and also internal cards and see if it boots. If it does then reconnect one device at a time til you find the culprit
That's pretty much all you can do without swapping out parts.
Turn the computer off.
Disconnect the AC power supply.
Remove the battery.
Remove the disk-drive.
Reconnect the AC power supply.
Turn the computer on.
Put any "data" disk into the CD-drive.
Does it display the CMOS boot-up display?
Can you hear the PC try to spin that "data" CD, i.e., trying to "boot" from it?
If it works "better" without the disk-drive attached, the disk-drive is the problem.
Take a multi-meter, and test the voltage and amperage outputs from the power-supply, to confirm that the readings match the specifications on the label on the power-supply.
If the power-readings are correct, then when you connect the power to the external enclosure, you should either hear the disk-drive start to spin, or feel the vibrations as the disk-drive spins.
If you don't, then the disk-drive inside the enclosure has "died".
If the device is still under warranty, MAXTOR will replace the disk-drive, for minimal costs to you.
If the warranty has ended, then open the enclosure, remove the disk-drive, purchase a new, compatible, disk-drive, install it into the enclosure, and thus "revive" your external storage device.
If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.
Try it on another PC or on a powered USB hub: maybe it's not getting enough power to run.
If it still doesn't work, and you don't hear the drive's spin-up noise, the electronics may be damaged, the internal disk disconnected or the internal power connection faulty.
If you hear the spin-up whirring and then a series of repeated whirrs and clacks, ending after about 30 seconds - one minute, the disk might be damaged. It still might be recoverable if extracted from the case and connected directly to an appropriate hard disk port (a 3.5 to 2.5 adapter might be necessary), but when things go this far, the chances aren't too good.
This fault usually means the hard disk has failed or the disk controller, in most cases it is the hard disk that has failed.
Check the BIOS settings and see if the hard disk is detected, if not it is probably a faulty hard disk.
When you boot up the computer does the hard disk LED light flash and can you hear the hard disk spin up. If the hard disk is making a clicking noise then it is definitely faulty.
To test the hard disk another way, remove the hard disk and connect it to an USB hard disk adapter and connect it to a working computer's USB port. If this computer cannot detect this as an external hard drive and you can't open the folders and files, this confirms it as faulty.
To get the computer operational again, you need a new hard drive, Install Windows on the new hard drive with the computer's device drivers and your programs.
remove it from the case and put it straight into your computer using a spare power plug and cable. to see if you are doing it right check one of the other hard drives in the tower switch on and see if there is any diffrents if not then i am sorry to tell you it is caput
