History
In the classic Mac OS, similar functionality to the verification features of Disk Utility could be found in the Disk First Aid application. Another application called Drive Setup was used for drive formatting and partitioning and the application Disk Copy was used for working with disk images.[citation needed]
Before
Mac OS X 10.2.3.[5] Further changes introduced in Mac OS X Tiger, specifically version 10.4.3, allowed Disk Utility to be used to verify the file structure of the current boot drive. Mac OS X Leopard added the ability to create, resize, and delete disk partitions without erasing them, a feature known as live partitioning. In OS X El Capitan, Disk Utility has a different user interface and lost the abilities to repair permissions due to obsolescence,[6] create and manage disks formatted as RAID, burn discs, and multi-pass format internal solid-state drives and encrypted external drives.[7]
