All my drives are installed inside the server chassis, so I'll just remove the HBAs which will have the same effect. Reading back through many, many old posts on the subject, I believe I've been looking at this all wrong. The actual information Drivepool uses to build and maintain the pool is stored on the pooled drives, not on the system disk, so its just a matter of reinstalling Drivepool and it goes looking for the poolpart folders on the physical drives in order to rebuild the pool. I'm not sure why I've been thinking I needed to worry about what was on the C: Drive, other than that's where I placed the junctions for the drives on my system, but that seems to be more of a housekeeping feature to get around the 26 drive letter limit more than anything to do with Drivepool itself. If this is correct, I believe I'm ready to go.
It would seem that Stablebit Drivepool is quite a feat of engineering.
