I'm using Disk Utility and have 2 36gb Raptor hard drives that I want to use in Raid 0 with OS X. I'm using Disk Utility on the OS X DVD. They've been partitioned to a single partition each, and the files system is correct. But when I try to drag it, there is nothing at the end of the mouse. Both drives have been verified and appear fine. Any ideas? I tried on another machine and it seemed to drag OK with a single drive but I didn't have a second drive that hooks up to that machine to test it further.
