ARCHIVED: In Mac OS X, what is Disk Utility, and how do I use it?
In Mac OS X, Disk Utility is a multipurpose program for working with hard disks, disk images, CDs, and DVDs. Depending on your version of Mac OS X, you can use Disk Utility to perform the following functions:
- Erase, format, and partition hard disks and rewritable CDs and DVDs
- Run First Aid, a function that repairs file systems and file permissions
- Stripe or mirror disks in a RAID
- Mount, create, and modify disk images, as well as write or burn them to disks, CDs, and DVDs
- Manually eject removable media when other methods fail
Disk Utility is in the
Utilities folder inside the main
Applications folder. It is also available on Mac OS X
software installation CDs and DVDs, and, in Mac OS X 10.7 (Lion) or
later, on your
Recovery HD volume. For more about using
