thats just hardware detection, all hardware will show up there does not mean its working properly. try load the drive by itself ( set the jumper to master) if the pc boots and tell you cannot find ntdlr then the drive is good. did you get a cd with the drive, boot from the cd and set up the the drive. THE drive has to be formated for the operating system to see it.
I see that you have the same post and Jbennet suggest you use computer management, if the drive show up there you can format it
