Hello. Newbie here. I've been following this posting for several hours now while I work on a friends machine and I simply cannot get past the following error msg: "The device associated with following device driver will not work correctly on this computer: nvraid.sys. The device driver is not compatible with the x64-based version of Windows your computer is running" First, forgive me for my inexperience with RAID setups. I have verified all the steps in your tutorial are correct; RAID enabled in BIOS, array cleared and healthy and unattended win xp 64b boot disc created with the driver from the "64bit nForce SATARAID drivers v9.99.09 mod by Fernando" using nlite. Some quick details about my issue. The PC was originally running with Vista but the owner has had problems since inception with corrupt arrays. He purchased this copy of Win XP Pro 64 bit and has asked me to load it for him. Obviously it does not have a floppy drive. So, If I am following your tutorial correctly, I'm guessing I have one of two problems, or both: 1. The Win XP 64b install disk is Service Pack 1. I have downloaded the SP2 installation file but when I try and incorporate that into the unattended installation setup thru nlite I get an error because the machine I am using is a Vista 32bit machine (only 64bit slipstreaming is supported from a 64bit OS). Is there any correlation to my issue here? -and/or- 2. As I have underlined and bolded above, the error msg specifically indicates the problem is with driver: nvraid.sys. Again, if I am following your tutorial correctly, shouldn't this driver be: nvrd64.sys? If this is the case I am guessing that deleting and clearing the array is not erasing, or allowing an over-write of, the old driver? Any and all help is greatly appreciated (even if it's some little stupid step I missed).
