WHAT IS DISK UTILITY ON MAC FOR MAC OS X
If the drive is formatted in Mac OS X Extended (Journaled), then by default, journaling is active on the drive. Additionally, restarting the system gets faster due to journaling.
However, the data that was in the buffer while the system failed, may be lost but the system is reinstated to the working state. In an event of an abrupt shutdown of the system due to power outage or another failure, these journal entries make it possible to restore the system to the last known consistent state of working. All of this happens automatically on OS X. These entries are maintained in a special type of data structure called “ Journal”. When the journaling is enabled on Mac, it keeps record entries of the changes to the files present on the disk. Journaling is a Mac OS X feature that is extremely helpful in protecting the system against the problems that arises due to power failures, hardware failures and directory corruptions. Topics covered in the blog are as follows: Would you like to try our data recovery software on your Mac? The demo is absolutely free.
Moreover, its functionalities may also access from Mac OS X command lines with the “diskutil” and “hdiutil” commands.Summary: This blog helps you know more about hard drive journaling on Mac. Disk Copy was used for mounting and creating disk images files where as Disk Utility was used for partitioning, creating, fixing and checking file structure. Prior to version 10.3, its functionalities were spread across two applications such as Disk Utility and Disk Copy. In Mac OS X 10.3 version, disk utility function was updated. Examines the SMART status of a hard disk.Fixes if the disk is corrupted and verifies data integrity.Secure deletion of free space or disk using a “ a 7-pass DOD 5220-22 M standard, zero out data, or a pass Gutmann algorithm.Adding and changing partition table between GUID Partition Table, master boot record and Apple Partition Table.Recovers volumes from Apple Software Restore images.Writing disk images to DVD or CD in HFS+ format.
Creating, merging, repairing and destroying RAID sets.Formatting, erasing, cloning and partitioning disks.Ejecting, mounting and unmounting disks including removable media, hard disks, disk images.Once you start “Live Verification” process, you cannot stop in middle and you might face some problems if you attempt to check or fix any unmountable and non startup disk.ĭisk utility performs disk related tasks, such as In addition, during this process, the Disk utility progress indicator may stop advancing and open apps become unresponsive, computer may freeze or the progress pointer may appear. Disk utility prompts a message: “Error: could not freeze volume” when you try to check a non-journaled disk.

Live verification works on Mac OS X Extended formatted volumes.
WHAT IS DISK UTILITY ON MAC FOR INSTALL
If this tool finds any problems that needs to fix it so you need to start up from your Mac OS X install DVD and use Disk utility on that disk. In addition, this tool is also called as “Live Verification” because it is used to verify computer startup disk without starting up from another disk. Disk Utility is an application, developed by Apple for performing disk related tasks such as conversion, compression, encryption and creation of disk images.
