I'm not really sure what motherboard you have or what sata controller you are trying to use. This I do know, if you have a sata raid controller (I have 2, abit with highpoint AT7MAX2 and Asus with SI Nforce2 ,you should set it up first as a single drive with no other drives attached. You will also have to go into the controller bios and setup the drive a raid 0 with just one drive. When the computer boots it should show the drive by itself in the controller bios screen. After that follow my suggestions in the previous post and you should be OK. The RAID should be turned on in the system bios and set to boot to it. If your bios has a boot sequence the for the Raid or SCSI set it to that. The errors I've read do not sound like a bad drive, just incorrect setup. Usually when you get bad dll errors it can be the wrong driver is loading in windows. Remember that until windows loads it uses a generic driver that just allows minimal IO to the device until the right driver can be loaded.
