RAID1, raidhotadd, >1024 cylinders

[Benjamin de los Angeles Jr .]

I'm having some error message when I tried 'raidhotadd' on a
RAID1 array, which consist of 2 IDEs the # of cylinders is 1048, 
heads is 255:

ll_rw_block: device 03:02 only 4096-char blocks implemented(1024)

EXT2-fs error(device ide0(3,2):ext2_write_inode: unable to read
inode block-inode=4081, block=16392
....
similar error follows... with different block-inode and block #'s.

What could be reason?

This is my setup:

/dev/hda2 + /dev/hdc2  (/)
/dev/hda4 + /dev/hdc4  (/usr)
