Disk inconsistency and file system problems are some of the problems faced by every computer, Running on different OS at any point of time,including Mac OS X. Mac OS X provides Disk Utility and fsck tools to handle such situations,Both of them are able to detect and fix at certain extent hard drive and file system related problems But these tools have certain limitation and they cannot handle all the issues efficiently in Those cases you are required to opt for Mac File Recovery solutions through appropriate tools.
When you run Disk Utility or fsck command on Mac OS X hard drive to check it for errors, You May Find some messages like
“overlapped extent allocation”
The disk checking process gets stops with above error message. It leaves all your data inaccessible. In order to retrieve data in such situations, you need to find out the main reason why the message is displayed and after finding that Mac File recovery is performed to fix it.
Root Cause of the issue:
As stated in the above error message, problem is caused due to "overlapping of allocation space". When this message takes place in Mac Operating system, it means that the same disk space is allocated to two files. Thus, it is certain that one file among them would be deleted. Solutions of the above problem exist, but you need to ensure that More data is not lost. Thus, it will be a wise step to recover lost data first and then fix the current issue.
To resolve the issue these things should be done:
1) Perform Erase and Install Operations in Mac OS X using installation disk. But You should always back up all your important data before you go for it.
2) Delete affected file and then all the data must be restored using the backup.
In case backup is not available, different data recovery utilities must be used like File Recovery Mac Software are required. These are the advanced and effective third-party applications, having very efficient scanning algorithm to perform in-depth scan of entire hard drive and extract all lost,inaccessible and missing files from it.
