The invalid B tree node error is such a condition, which arises with all Mac OS X users, when the machine is powered on and it does not proceed beyond the Apple logo on the screen. If the user tries a disk repair with booting from the Install CD and running the Repair utility, to repair the disk or trying to repair permissions, then the repair fails and the error on
“invaild B tree node size” appears.
The error appears when the there is a severely corrupt volume and that needs to be accessed. This causes hard drive to corrupt & compromise with data inside. When the OS X fails in its effort to transverse this, then it flashes this error. All this happens due to corruption and sometimes it leads to a Mac boot failure, causing data inaccessibility.
The Mac volume consists of files, directories and directory threads. Each and every saved file will be saved in the index table in the B-tree format. OS sets the location of the file by accessing these entries in the index table.
One of the solutions is the reinstallation of the hard drive and the OS as well as all the applications. If there is no backup of data, then this can be indeed a time consuming effort. Without the backup copy, the data gets lost.
The solution lies in trying something else other than reinstallation. The manual running of the Apple File System check (fsck) can be used to repair invalid node structure mac error.
If the error still persists, then the cause of the corruption is much deep rooted and a Professional Software needs to be used. This Mac Data Recovery Software will have a rebuild option for bringing back the computer to its operational stage. However, if the volume is severely damaged it needs to be deleted and then recreated. This requires a backup of the data, which is done recently for all your crucial business data.comments powered by Disqus
