Users of Linux/Unix are familiar with the lost+found directory, where the operating system stores content in case of inconsistencies/problems with the file system. For the first time since owning a Macbook I discovered a lost+found on my harddisk. Good news: It was only the remains of the latest MacOS update.
Checking the content of iNodes in the lost+found directory is easy:
- Open the OS X Terminal
- List the files in the iNode: xar -tf /lost+found/iNode#######
- If necessary the files can be extracted from the lost+found iNode: xar -xf /lost+found/iNode#######
