Noe, Zahlen falsch:
/usr/share/doc/howto/en/html/mini/HOWTO/mini/Ext2fs-Undeletion-Dir-Struct/index.html
"* The block numbers of the first 12 data blocks are stored directly
   in the inode; these are sometimes referred to as the direct blocks. 
 * The inode contains the block number of an indirect block. An
   indirect block contains the block numbers of 256 additional data
   blocks. 
 * The inode contains the block number of a doubly indirect block. A
   doubly indirect block contains the block numbers of 256 additional
   indirect blocks. 
 * The inode contains the block number of a triply indirect block. A
   triply indirect block contains the block numbers of 256 additional
   doubly indirect blocks.

Read that again: I know it's complex, but it's also important."
