Keep in mind that the OS gets to choose exactly what occurs when a file is deleted and this article assumes a general Linux system. At a minimum, the OS must mark each of the blocks, the inode, and the directory entry as unallocated so that later files can use them. This minimal approach is what occurred several years ago with the Ext2 file system. In this case, the recovery process was relatively simple because the inode still contained the block addresses for the file content and tools such as debugfs and e2undel could easily re-create the file. This worked as long as the blocks had not been allocated to a new file and the original content was not overwritten. With Ext3, there is an additional step that makes recovery much more difficult. When the blocks are unallocated, the file size and block addresses in the inode are cleared; therefore we can no longer determine where the file content was located. We can see the relationship between the directory entry, the inode, and the blocks of an unallocated file in Figure 2" Cheers Manuel -- Manuel Arostegui Ramirez.
