A Mac OS X-based hard disk is divided into two partitions, each of different characteristics. There are four basic things contained in each of the partitions, they are files, file threads, directories and directory threads. Catalog files are used by the Mac OS to define these basic record files. Each Catalog file is placed in the B-tree formation. Therefore, if you want to locate a file the system will search the entire B-tree formation.

There are however, cases wherein the tree structure or the nodes undergo some issues that require formatting the volume. Formatting the entire structure means the loss of data viz. files, directories and others, this calls for making a back up before reformatting. However, if a user doesn’t make any back up and wants to recover data lost as a result of a B-tree structure failure, then Mac recovery solutions would come in handy.

Usually users will come across an error with Mac volumes that says “invalid B-tree node size”. This error is observed under hierarchical file system based volumes. You come across this B-tree node size error while verifying the integrity of the files and directories using Disk utility. These kinds of errors are encountered if the node size of the B-tree is not correct. Invalid node sizes of the B-tree is one of the major problems that one faces in a Mac OS but there are obvious ways to fix invalid b-tree node size error by using an efficient third party Mac data recovery software.

To resolve the issue of B-tree node size problems, one can find solutions that include:

Disk utility is not an efficient utility program because it is unable to get rid of the error. One can run fsck. It should be used in a single mode.
There are third party disk repair applications, i.e. REMO Mac Recover. These are data recovery and repair solutions that eventually repair the invalid b-tree node size mac os x error.
One of the other ways is to make a back up of all the other pieces of data from your Mac and perform a reinstallation and then you can run Mac data recovery solution for efficient B-tree node repairing.

REMO Mac Recover is a recovery applications which employ improved and efficient scanning algorithms and retrieve files in their original form, regardless of the data loss situation. Why not Download REMO Recover for a FAST way to fix invalid b-tree node size mac os x error?

twitter.com Matt Ryan of The Frugal Geek blog on Lockergnome shows you how to lock your Mac OS X Screen using a password protected screen saver. From the Desktop & Screen Saver settings in Mac OS X, be sure you have turned on a screen saver. You then configure a hot spot on your screen to activate the screen saver when you move the cursor to that location. Configure the password for your Mac OS X user account. From the Security System Preferences page, check the box to require your password be entered when screen saver is activated.
