Disk Utility can find and repair errors related to the formatting and directory structure of a Mac disk. Errors can lead to unexpected behavior when using your Mac, and significant errors might even prevent your Mac from starting up completely.
In general, you can just open Disk Utility from the Utilities folder of your Applications folder. However, if your Mac doesn't start up all the way, or you want to repair the disk your Mac starts up from, open Disk Utility from macOS Recovery:
The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. And beneath each disk you should see any containers and volumes on that disk. Don't see your disk?
In this example, the startup disk (APPLE SSD) has one container and two volumes (Macintosh HD, Macintosh HD - Data). Your disk might not have a container, and it might have a different number of volumes. Repair volumes, then containers, then disks For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.
The order of repair in this example was Macintosh HD - Data, then Macintosh HD, then Container disk4, then APPLE SSD. When done, quit Disk Utility. If you used Disk Utility from macOS Recovery, you can now restart your Mac: choose Apple menu > Restart.

Disk Utility is free and is the first tool you should try after restoring and backing up your data. Unlike Disk Drill, Disk Utility may directly repair the affected drive, and the process may cause data to get overwritten on the disk.
Besides recovery, Disk Drill is also great for resolving hard drive errors. The app also comes with dozens of free tools such as HDD cleanup, data backup, disk monitoring, duplicate cleaner, and more. This makes it a great all-in-one solution for all your disk problems.
Proper maintenance is the key to keeping your disk in top shape, and you will hardly find an app that is as packed with features as Drive Genius. The tools are separated into 3 groups: Protect, Clean Up, and Speed Up.

The Disk Utility app bundled with Mac OS X has a command line equivalent which offers advanced users the ability to perform disk maintenance from the terminal, including disk verification and repairs. This allows for a variety of helpful troubleshooting abilities, including the possibility to remotely issue disk repairs though SSH, or through Single User Mode if the user accounts are inaccessible.This guide is intended for advanced users who are comfortable with the Terminal and command line. Most Mac most users are better off sticking to the graphical side of things and repairing drives directly with with Disk Utility or through recovery mode.

I have an external hard-disk with a single Mac OS Extended partition. This disk stopped working couple of days ago. I tried to repair the partition with disk utility but no luck. The error message is the following:
The -r option rebuilds the Catalog B-Tree. Not sure why disk utility doesn't do this automatically. The -d option shows extra debugging information. See Repair disk from single user mode (fsck fails) and the fsck_hfs man page for details.
Is this an external drive you're sharing between a Mac and a Windows PC? I've had this issue a few times with a disk formatted FAT32. If you don't unmount your disk properly when you remove it from your Windows PC, the whole volume will be marked as "busy" and you'll be prompted to repair the volume if you look at it in Apple's Disk Utility. However Disk Utility will fail to repair the volume, and report:Can't open (Resource busy)File system check exit code is 8.
I had this issue with an external disk in ExFAT, nothing worked. I was just about to use recovery software but boot into Windows, Windows read it fine. Booted back into OS X and now everything is as it should be. Weird.
I had a similar problem with my external Toshiba HD- my macbook wouldn't recognize the HD until after unplugging it and then prompted for a password (which hasn't been applicable for months). I tried all possibilities of a previous password, received the same error message in disk utility when trying to repair the HD, and finally was able to correct this error by utilizing the free OS upgrade to Yosemite. Hope it helps!!
You first need to determine whether the problem is with the disk hardware or the filesystem. To learn whether the hardware is failing, you can use a utility that will evaluate the SMART data. Apple's Disk Utility does a limited form of this, but it's not nearly as reliable as a dedicated tool. I use SMART Utility -- the free trial will provide all the info you need for a one-time diagnosis.
Therefore, I recommend that you use the product Data Rescue for this recovery job. It scans the entire disk (takes a while), searching for "lost fragments" of the catalog, trying its best to recover as much as possible.
With a disk that's marked unrepairable, you should not try to keep writing to it (in fact, it should be made read-only, which is, sadly not as simple any more as it used to be long ago), because any further writes may overwrite valid data, due to the damaged catalog.
My computer crashed and damaged directory files on my external hard drive. So it wouldn't mount but I could see it in Disk Utility (altho it wouldn't repair). Paid the $120 for the diskwarrior, went thru everything and it was fine. Gives you a preview to grab files too before they go in and fix the bug. Worth the money.
While this is still the case while booted in most versions of Mac OS X, you can repair the Mac OS X boot disk thanks to Mac OS Recovery Partition, preventing the need from using an external boot drive to repair the disk.
