[NTLUG:Discuss] HELP!

The other day, I lost power to a backup machine I have.  It is a Compaq 
(please don't hold this against me), with SCSI drives in there.  I had 
someone from the list help me set this machine up, etc....but having 
problems now.  When trying to boot up (Red Hat 7.3), it tries to find the 
drives that were "Raid ed" together.  There were four, but one died a while 
back...so the remaining three drives.  The drives are /dev/md0.  Partial 
way through the boot, that "drive" fails to be read....thus prompting the 
following:

fsck.ext3:  Invalid arguement/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 and ext2 
filesystem (and not swap or ufs or something else), then the superblock is 
corrupt, and you might try running e2fsck with an alternate superblock.:


e2fsckj -b 8193 <device>

while trying to open /dev/md0					[FAILED]



*** An error occurred during the file system check.
***Dropping you to a shell:  the system will reboot
***when you leave the shell.
Give the root password for maintenance
(or type CTRL-D for normal startup		(which it will not do)


Can I get into a command line editor to undo the Raid drives?  I have 
removed the actual SCSI drives that were in the Raid, for a modified IDE 
drive running a SCSI controller.  I need to format that new drive, and tell 
Red Hat go look HERE now for the new partition etc.

Can someone shed dome light on this for me?  I'm not a true Linux 
"guru"...but have been playing around with it now for almost a 
year.  Command line is not one of my strengths.....so...PLEASE spell out 
what I need to do.
