on studying ext2 and ext3 file systems i found that starting block(or physical sector) for inode tables in a group differ from version, block size and partition size. Can anyone please help me out by telling me a general formula to locate starting sector (or block number) of inode tables in a group. Those groups which have super block and group descriptor block, Inode table location can be found easily. but those groups which don't have super block and group descriptor block there is no general formula.
please help me out
