Re: Where is inode table

[Raj Mathur <raju@xxxxxxx>]

As far as I remember the i-nodes start immediately after the
superblock for any filesystem.  In orlder Unixen that used to be at
offset 512 from the beginning of the FS.  Try 512, 1024, 2048 and 4096 
bytes from the beginning of the FS.

The structure of the innode on the disk is given in

	/usr/src/linux/include/linux/ext2_fs.h

The superblock structure on disk is also igven in the same file.
Experiment around a bit.

!!WARNING!!  Make sure that your call looks like open(...O_RDONLY)!  I 
mean, O_RDWR|O_TRUNC would be a /very/ bad idea :-)
