hi ya

i dont quite understand the problem... besides the typo like /dev/rooot

if you are looking to "see"  /dev/hda2  and /dev/hdb2
separately....
        - you wont ... its been raided together
        

if you are trying to hotadd ...  you need to hotremove it first...
and might even need to hotsetfaulty first ...
        - after the hotadd does work.. than yo can watch it resync
        ( cat /proc/mdstat )

===  and make sure the partition type on /dev/hda1  is fd type
        since it's not part of /dev/md1 yet

--- make sure the disk itself is good   
        assuming you dont care about data on /dev/md1 
        -- boot in standalone mode...
        -- mke2fs /dev/hda1
        -- mount /dev/hda1 /mnt/test
        -- copy xxMB of junk to /mnt/test  and compare to the original

        now go go back and manually rebuild /dev/md1
        -- mdadd /dev/md1 /dev/hda1 /dev/hdb1
        -- mke2fs /dev/md1
        ...

have fun
