The idea setting up everything without the SATA drivers is a good one. If I can't get this working I'll go ahead and do that. I'm not 100% sure that there isn't something else going on here BAM. The drivers for my controller appeared to be the same to me as well. I've been thinking that maybe I was doing something wrong here. It is possible that the stop errors are from something else. However, this is exactly the same place I got the stop errors when I was first learning to integrate a SATA driver a year ago. It's like the CD loads it on first bootup and is able to format the drive. Upon reboot, the driver does not load and is not able to pickup the install from the hard drive. My latest efforts have been to minimize this possibility. My exact procedure has been to use the latest Nlite to slipstream in SR2 and disable the file protection. After that I go through the installation of the BTS Driverpacks exactly as directed in the extended intructions. I'm not using any of my usual application adding or registry tweaks. I haven't added a thing from what I've told you. Windows is not my strong suit but I'm still fairly competent with it. I've created slipstreamed installs before (manually) without problems. Having all the drivers included with the BTS install is very appealing and I'd like to get that working if possible. The only possible thing I can think of that might be interfering with the SATA driver is the fact that it is installed to the SATA2 port instead of SATA1. The first SATA port had the plastic cover break off during initial installation. The SATA port still works fine, but without that plastic cover, it will not stay in place firmly when hooking up the drive. The system works fine on the second SATA port. I only mention it because it is the only thing I can think of that is not completely standard. I can't imagine that this would make any difference but I could be wrong. I'm sort of grasping at straws here and I'm open to any suggestions, no matter how remote a possibility. I'm leaning toward the suggestion of just putting in all the drivers but the MassStorage ones and adding the two or three most common ones I use manually. I'm going to give it some time to let others read these posts and offer any other suggestions first. None of this just makes any sense to me. From what I can tell, this should be working. One last note, I have downloaded the drivers once again (one at a time) just to make sure that there is no corruption as other seem to have had this issue recently.
