Can you(anyone) please tell me the answers to the following:
  1.How many inodes are there in a single block	?
  2.After a inode is deleted , is it appended to the end of free inodes list?
  3.Is there any preference in which the inodes are allocated in choosing 
between inodes that has never been allocated and inodes which were once 
allocated but are now free?
  4.Doess the data in an inode remains unchanged when it is deleted?

It would help me immensely if I get the answers to the above.Thanks in advance 
for all the help you can give.
