I'm not sure what "ataraid" is.  Are you using the dmraid utility?  It 
creates devices in /dev/mapper for me.  Also what kind of raid array is 
this?  If it is a mirror then you should be able to replace the failing 
drive and go into the bios raid setup program and rebuild it with the 
new drive.
