Hi all - new member of the forum - found Fernando's post on NVRAID installs, read through many of the pages, and it looks fantastic. Couldn't find my solution exactly, though. Before I kill data on my drives, I thought I'd ask for some advice. Though I've mastered plenty of weird XP quirks, this one's slightly beyond me. System: Asus nForce5 590SLI (M2N32SLI Dlx) GeForce 8800GT 2x 74GB raptors (RAID 1) (Edit: fixed RAID type) 2x 160G Hitachis (RAID 1) (Edit: fixed RAID type) 1x 500G Seagate 1x 250G WD (fresh drive) I was having some BSOD errors yesterday, so decided to upgrade drivers in case that was the problem. Went to NV nForce 15.25, and it killed the nV RAID. Drives are still there, but during POST, the pc hangs at "Detecting Array" if I try RAID-enabling the Raptors in BIOS. If I leave them as JBOD, but RAID-0 the Hitachis, POST says "Healthy" array, but WinXP Pro doesn't see them at all. I've re-installed XPpro on the 250G, but didn't do the F6-install for drivers, just trying to see if all my data was on the HDDs. It is. Now, the system's booting off one of the Raptors, but only in JBOD mode. DevMgr says the NVRaid controller's working properly, Ver 10.3.0.46. But no RAIDs visible. Any ideas? I'm copying all data to the SG & WD drives in case I have to do a wipe, but I really, really want to avoid that. Or, if I drop the Raptors to JBOD, and do a fresh XP install on one of them, then "rebuild" the array, can I tell it which directories to mirror from each drive? Or would I just be SOL? TIA, Jim/ByTor
