Background info: - Abit AB9 motherboard - 2x WD Raptor 150GB in RAID0 - 1x Seagate 500GB Windows is installed on a RAID array consisting of two 150GB WD Raptors plugged into SATA8/9 (Jmicron RAID controller) The hard drive in question in the picture is a 500GB Seagate plugged into SATA1, which I think is an Intel controller (ICH8?). Plugging it into SATA2 didn't change anything though. The Jmicron controller has up to date drivers (I had to use them in Windows setup so it could even see the RAID array). The other controller doesn't, as far as I know. I went to the Intel site to get updated drivers and the program I downloaded informed me that my hardware isn't catered for, apparently The Seagate drive is more or less brand new and up until yesterday was the drive Windows was installed on (I got my raptors back and decided to format everything and use the raptors as system drives) with absolutely no problems. Questions: - What hard drive errors would cause windows to appear with such a message? - Any fixes?
