I've never needed to sysprep to make a recovery image. Just use the tools, booted from WinPE, to snap an image of the two partitions on the boot drive to a file share or USB disk.
I've had systems with intermittently bad HDDs.. was able to snap the image to a server, replace the HDD, create the partitions and push the images back to the new HDD. Total time less than 30 minutes.
