Thank you so much for your immediate reply... I still have some problems though. I must have windows on the raptor, so I cannot unplug it during installation. The RAID array has all of my backup stuff, such as the My Documents folder, and every picture I've ever taken. The Raptor is what I use for windows, because it's small and fast. I simply cannot format the RAID array and use it for windows, because in doing so, I'd erase everything that I want to keep when reformatting and reinstalling windows. I must have been unclear when I described this problem... When I plug in my external hard drive (not the SATA RAID array) or a USB Flash Drive (a sandisk cruzer w/ U3), it goes into the "Found New Hardware Wizard", and it cannot find any drivers for it. Meaning: Otherwise Plug-N-Play drives require drivers... drivers that I do not have... drivers that are supposed to be part of windows when you install it. Anybody that has a USB Flash drive relies on the fact that all they have to do is plug it in for it to be recognized... These drives are SUPPOSED to be UPnP in Windows XP, but my computer "Cannot Install this Hardware" according to the Found New Hardware Wizard. I cannot get any Flash Drives or USB External Hard Drives to be recognized with a drive letter in my computer... This issue is completely separate from my SATA drives being recognized. A reboot does not help, and interestingly, the "where do you want to install" portion of the windows installation recognizes all three drives (raptor, raid array, and usb)... I would think that if windows recognizes them to install to, they would be recognized after installation. What I was referring to when I said "the first few times I installed nLite, the D: partition was recognized," was the fact that, after the first 2 or 3 nLite installs of windows, both the Raptor and the SATA array were recognized w/o a problem... and I thought everything was perfect until I plugged in my flash drive, and Windows couldn't install it. After the 3rd install or so, and up until this most recent one (I'd estimate to be #30), my D: drive is no longer recognized immediately, and I have to pull the "Compaq SCSI disk array" trick in the Device Manager to get it in Windows Explorer. One other thing that I just remembered... The only time that I can remember that I got all my drives (raptor, sata array, and usb) recognized perfectly, I had turned "Data Execution Protection" on the Unattended tab to "Always On." It was nice being able to recognize all my drives without pulling any tricks... but DEP wouldn't let me do ANYTHING, since even opening Internet Explorer was going to "cause damage to my computer." When I put DEP back to default using the preset config from the disk I had just burned, and ONLY changed the DEP setting... it went right back to not recognizing my sata array or external usb drives. What does Data Execution Protection have to do with recognition of my raid array or usb drives? Thanks again for your immediate response. You seem to be very knowledgable, so I look forward to your next reply.
