While these features are relatively apparent, the program does have some often overlooked options that can be useful. Alternative checksums Use a Terminal command to expand http://www.macworld.com/article/2871803/unlocking-disk-utility-s-hidden-secrets.html Disk Utility's checksum options. The first of these is the hidden checksumming routines for verifying disk image files. If you have an image, especially an older one, you might wish to verify its integrity before opening it. This is usually done when the image is opened, but you can also do it manually by adding an image to Disk Utility, selecting it, and choosing Images > Checksum > CRC-32 image checksum. This is fine, but often developers (including Apple) will issue updates and other software in disk images and include an SHA or MD5 checksum that you can use to verify the image’s integrity before opening it. However, these options are hidden in Disk Utility by default. To enable them, follow these steps: 1. Quit Disk Utility. 2. Open the Terminal utility. 3. Run the following Command: defaults write com.apple.DiskUtility advanced-image-options 1 4. Relaunch Disk Utility After performing these steps, the Images > Checksum menu will have

Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

You should check several things if you haven't already: Is your CRC error count at 0? Is your Pending/Removed/Reallocated Bad Sectors at 0? Have you run random read/write block tests on the drive? Look into a shareware program called SMART Utility if you haven't run any of these checks already. I highly recommend it for basic drive health checks. –Fyrefly Jul 3 '14 at 16:30 add a comment| 14 Answers 14 active oldest votes up vote 14 down vote There is a chance to repair it with command line (in Terminal) with the terminal utility as described in Apple's support docs, shown below: Use the command line and the fsck_hfs -l command.
