I have a Western Digital 250GB HD and controller card. My computer is a Dell Dimensin 4550 from 2003. I've had this for 2yrs now and everything has been fine until I guess sometime last night. I was out and my computer was shutdown however we suffered a power outage at my house. When I came home to day and booted up my computer I got this message: ultra100TX2 BIOS is not installed because there are no drives attatched I have tried using different cables, placing the controller card in a different pci slot but I always get that message. Does anyone know what the problem is? Is it possible to save my hard drive because I had a lot of stuff on it? I tried to connect the hard drive straight to my motherboard and bypass the controller card. When I did this the Dell Bios recognized the HD when I went into bios, however it then gave me a disk read error and said I had to reboot. Any help would be greatly appreciated.
