Common beliefs think that when data is deleted from the hard drive, it is deleted forever. There is no mean to (Mac) undelete files from Mac OS X hard drive. In fact, it is a wrong perception that you cannot undelete Mac or the files are deleted permanently once you emptied trash bin as you could neither find it in the trash, nor under temporary folders. Actually the files are still very much present on your hard disk. Mac OS X creates index of the file on hard drive in file system. Every data has entry in the file system index, which includes name, location, size and type. When it is accessed from the hard drive, the index is accessed by the operating system. Operating system reads the storage location of the file to extract the file. When a file is deleted, only the index entry is deleted and the disk space occupied by the deleted data is marked as free and re-useable space, so it is possible to undelete Mac until the file is overwritten by other files.
2 Ways to Undelete Data from Macintosh
1. Time Machine to Restore Data from Backup
Mac machines purchased after November 2007 are installed with the Leopard operating system. One of the most important utilities of the Leopard is Time Machine. This complete backup tool can backup almost anything and everything on a Mac every hour with its unique features. Once you deleted or lost your critical files, just enter your Time Machine browser, and you can undelete Mac files from Time Machine backup. Besides Time Machine, there are other programs on Mac such as Backup which allows you to undeleted Mac files. In Backup, you simply select a plan for backup, and find the files you want to undelete.
