How To- Perform Disk Maintenance and Fix Startup Issue in Mac Using fsck and Disk Utility?
If your Mac OS X computer does not boot up normally, you may have to use disk repair tool to work around the problem. Mac OS X operating system includes two programs for this purpose- fsck (command-line tool) and Disk Utility. These programs can be used to check the integrity and consistency of your Mac hard drive and file system, even if your system boots up normally. However, in some cases, these utilities cannot fix the severe file system corruption issues and your system remains unbootable. This behavior leads to significant data loss and you need Mac Data Recovery to fix it up.
Under some circumstances, file system corruption or errors can render your system unbootable. This problem can take place after forced reboot, improper system shut down, or power outage. You must use disk repair tool, if your Mac OS X system displays any of the below symptoms at startup:
You computer boots up partially but then shows command line in text-only environment. At the same time, you may also see an error message like- “File system dirty, run fsck.” Under the error message, you see the command-line prompt, which enables you to run fsck command.
Your computer boots up however, either it does not reach to login screen, or may load the login screen but cannot load Desktop after login.
When you Mac computer demonstrates either of the above problems, there are some resolutions that you can try out to get your computer boot up properly again.
Boot in Safe Mode- Start your system in Safe Mode that includes automatic hard drive check and repair. After booting the system in Safe Mode, reboot it again normally.
Use Disk Utility- If the above method does not work, you need to run Disk Utility to detect and fix file system errors. Run fsck- If the problem persists, run fsck command-line tool at command prompt.When none of the above methods can solve your issue, hard drive formatting and operating system reinstallation is the last resort. However, it removes all data from hard drive and puts you in need of Mac Data Recovery.
You can perform Data Recovery Mac in a quick and easy way using third-party Mac File Recovery Software. The applications employ powerful scanning techniques, to ensure absolute recovery. They are quite safe and easy to use with read-only demeanor and self-explanatory user interface.
