Before you do ANYTHING with the drives, if you connect them to another identical RAID controller you can simply reestablish the array. However, if you mess with them, hook them up separately, you could damage the information and make getting the array reestablished impossible, then your data pretty much gone. RAID 0 makes data recovery very nearly impossible unless you can reestablish the original array as it literally splits all the data in half, byte per byte, across the 2 disks, and the "key" to piece it all back together again is on the drives as well.
As I always say, if you are determined to do what most of know is a bad idea and run RAID 0, you need a good backup going, because something like this will happen, sooner or later. good luck.
