In my (very limited) experience with RAID0, there is no "best case scenario". As you probably know, in a RAID0 array, write operations are striped between the two drives. This means that for the vast majority of files on the array, only a portion of the file lives on the good drive. Depending on how the drive has failed, there's a chance you may be able to swap out the controller card with a known good controller with the *exact* same hardware spin/firmware revision, but that's somewhat of a crapshoot. The other option is to pay a company like Ontrack to recover the data, but that can get quite expensive - often into the thousands of dollars. Not to get preachy, but this is the main reason to avoid RAID0 like the plague. Yes, there are some instances where RAID0 is called for due to performance needs, but that's surely not the case with an external drive. If you want to use RAID0, it's *imperative* that you use some sort of offline backup to CYA for instances like this. Good luck! -Erik
