I have two 500 Gb eSata drives set up as a RAID 1 mirrored set. I want to break the mirror and set them up as a Raid 0 so that I will have 1T disk. I am unable to "see" the RAID set in Disk utility (OS 10.5.5) and only see one 500 GB disk, which Disk utility seems to recognize as a RAID slice. (I have another RAID 1 w/ 2 internal drives that Disk Utility does recognize as a RAID set.)

Both drives are in the same housing. I have removed and re-inserted both drives. The casing has two power lights and both light up, which I assume means both drives are powered and running. Any help would be really appreciated!!!
QUOTE Thanks
