Data Recovery from a Dirty Mac File System
HTML clipboard
File system is the most important part of an Operating System. Every operating system uses a different kind of file system and Mac OS uses HFS. There are three variants of HFS file system which are HFS+, HFSX and HFS Wrapper. A stable and working file system is required for proper functioning of Mac OS. But sometimes due to improper system shutdown, virus infection and other similar causes, the file system gets corrupted and all your data becomes inaccessible. This behavior causes critical data loss and Mac Data Recovery is required to overcome it.
When you boot your Mac system, the process may fail halfway and it may prevent you to access data from the hard drive with the following error message:
“File system dirty, run fsck”
Mac includes an inbuilt file system check utility known as fsck. It runs automatically for checking and correcting file system issues if your system faces any problems like file system inconsistency during boot process. When fsck fails to correct the file system problems, you need to take other measures to correct the issue.
Resolution
There are four possible solutions to perform Data Recovery Mac by sorting out this issue:
Run system in Safe Mode. It is a diagnostic mode that is used by Mac OS X 10.2 and later versions while troubleshooting.
If this method fails, use Disk Utility. It is a powerful inbuilt tool in Mac OS to detect and remove file system errors.
When both the above methods fail, run fsck manually. To do so, you should have access of Mac OS X command prompt.
When everything else fails, opt for Mac Recovery software to recover all your mission critical data.
These software use efficient scanning mechanisms to thoroughly scan the whole hard drive and extract all lost data from it. Mac Data Recovery software are capable of retrieving almost all types of files including library files, application files, multimedia files, data files and more.
You can use these tools to retrieve data from most of the storage media as hard drives, USB flash drives, FireWire drives, CD and DVD images etc. With read only and non-destructive design, these software are completely safe to use and perform absolute recovery.
