raid0 created by mdadm can't be mounted after re-install the system


I have 5 sata disks on my computer and I create a raid0 using 4 disks to storage some data. Yesterday my debian 5 crashed while installing ati driver, so i re-installed an ubuntu 8.10 . After that I typed
Quote:
sudo mdadm --create --verbose /dev/md0 --level=raid0 --raid-devices=4 /dev/sdb /dev/sdc /dev/sdd /dev/sde
and mount it. However while today I updated 260 softwares via the web, it crashes again, so I tried to install debian5.0-lxde, but failed to boot because of a (hd0,4) partition error, so I changed back to ubuntu 8.10 . But this time when i use the same command to create the raid, it can't be mounted, the following error message is coming out:
Quote:
mount: you must specify the filesystem type
Anyone knows what is the problem?? Thank you very much.

Did you tried running this command on Debian too ?

no, I had not a chance to run debian because it is unable to boot, though I successfully installed it some weeks ago. While i typed
Quote:
fsck -t ext3 -a /dev/md0
it returns a message abount some inode error, and let me use the -b option, so I write a shell script to try from -b 1 to -b 10000 , and it works at about b=8200.
