Question RAID 0 Filesystem checking?

osĄGRed Hat Enterpris Linux ES release 3

i combined two harddisk to RAID 0 and format it to ext 3.
Then add the line "/dev/md0 /new ext3 defaults 1 1" into fstab.
No error occurred after run " mount -a". Everyting oK.

reboot system

When the filesystem check, error occur.
checking filesystems
fsck.ext3: /dev/md0:
The superblock could not be read or does not describe a 
correct ext2 filesystem.
If the device is valid and it really contains an ext 2 filesystem 
( and not swap or ufs or something else),
then the superblock is corrupt, and you might try running 
e2fsck with an alternate superblock: e2fsck -b 8193 <device>

Invalid argument while trying to open /dev/md0
How can i do to fix it?

-"/dev/md0 /new ext3 defaults 0 0" into fstab.

mount: wrong fs type, bad option, bad superblock on /dev/md0,
       or too many mounted file systems
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)
Show about error but i can enter linux.
it can't mount md0 (raid drive).

On the other side,
"raidstart /dev/md0"
"mount -t ext3 /dev/md0 /new"
md0 can be used!!
