Start up into Recovery HD and double click the Macintosh HD.
If it asks for, authenticate it.

Here’s how the unlock procedure works for Disk Utility:
1. Boot your Mac and hold down ⌘-R (Command –R) to boot from the Recovery HD partition.
2. Open Disk Utility.
3. Select your locked hard drive.
4. Under the File menu, select Unlock “Drive Name”
5. When prompted for a password, enter the password of the authorized account on the drive.
6. Once you unlock the disk, hold down the Option key on your keyboard and click on the File menu.
7. Under the File menu, select Turn Off Encryption… with the Option key held down, it is no longer grayed-out.
8. When prompted for a password, enter the password of the authorized account on the drive.
9. Disk Utility should display a progress window labeled Starting conversion to JHFS+
10. Your drive should now be unlocked.

Mar 1, 2014 1:57 PM in response to NYR315by Linc Davis,The drive is failing, or has failed. If you don't already have a current backup, you need to back it up immediately. Do not try repair it or reinstall OS X.

Mar 1, 2014 2:19 PM in response to NYR315by Eric Root,If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

Mar 1, 2014 2:26 PM in response to NYR315by Joe Bailey,You have three options
- Replace the hard drive
- Install an external HD and us it as your boot drive
- Replace the computer
If you are still under warranty of AppleCare Apple will replace the hard drive with a similar drive of the same capacity -- they will not upgrade your HD. If your warranty and AppleCare have expired you can find instructions for replacing the drive yourself at Other World Computing.

Jun 1, 2014 11:26 AM in response to NYR315by efurtado,Hi Linc Davis,
You say there are ways to back up a computer that isn't fully functional. Help! The only way I can get into my computer is via command>r. I assume I need to back up my computer before I do a reinstall. How do I do that. I tried disk utility repair and got 'Invalid node structure', 'Disk full error' and 'Error: disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files'. I have a Seagate external hard drive. I cannot get to my desktop at all. Can't reinstall Lion because the HD is locked, although I think I need to back up first if possible. I have tried double clicking the HD in the utilities window and nothing happens. FYI, when starting the computer with no commands I get the apple, the progression bar and then it shuts down. Thanks in advance!

Aug 14, 2016 8:01 AM in response to dhwolfpakby Eric Root,You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
Try using Disk Utility/Restore to copy the data to a new location. Please note that this will reformat the destination partition.
Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Then re-install the OS.
