mke2fs with blocks other than 1024?

[Tim Bell <bhat@cs.mu.oz.au>]

mke2fs doesn't want to make a filesystem with block sizes other than 1024.
It claims I have a bad block 0. For example:

	# mke2fs -c -b 4096 /dev/hda1
	mke2fs 1.10, 24-Apr-97 for EXT2 FS 0.5b, 95/08/09
	Linux ext2 filesystem format
	Filesystem label=
	130048 inodes, 130024 blocks
	6501 blocks (5.00%) reserved for the super user
	First data block=0                                            ****
	Block size=4096 (log=2)
	Fragment size=4096 (log=2)
	4 block groups
	32768 blocks per group, 32768 fragments per group
	32512 inodes per group
	Superblock backups stored on blocks: 
		32768, 65536, 98304

	Checking for bad blocks (read-only test): done               
	Block 0 in primary superblock/group descriptor area bad.
	Blocks 0 through 2 must be good in order to build a filesystem.
	Aborting....

whereas:

	# mke2fs -c /dev/hda1
	mke2fs 1.10, 24-Apr-97 for EXT2 FS 0.5b, 95/08/09
	Linux ext2 filesystem format
	Filesystem label=
	130048 inodes, 520096 blocks
	26004 blocks (5.00%) reserved for the super user
	First data block=1                                            ****
	Block size=1024 (log=0)
	Fragment size=1024 (log=0)
	64 block groups
	8192 blocks per group, 8192 fragments per group
	2032 inodes per group
	Superblock backups stored on blocks: 
		8193, 16385, 24577, 32769, 40961, 49153, 57345, 65537, 73729, 
		[etc.]

	Checking for bad blocks (read-only test): done               
	Writing inode tables: done     
	Writing superblocks and filesystem accounting information: done

Now, what I find interesting is that the first data block is 1 for blocksize
of 1024, and 0 for every other size (2048, 4096).

Any ideas here?

Thanks,

Tim.
