I bought a Caviar SE16 Serial ATA drive from Western Digital(SATA II).And all i got was this lousy message when i started up my PC.My mobo is an Intel D946GZISSLIt only supports SATA but i didn´t think i would have a problem since the drive is backwards compatible with SATA. I got the utility called Data Lifeguard Tools from the makers website and burned it to a CD and tried rebooting with that to see if my disk was kaput but i couldn´t boot from the cd either.Now i´m not sure if i burned the DLT right or something but i´m pretty sure i couldn´t boot from the cd either when i tried with the Windows XP Cd.And that cd works fine. The bios i just don´t understand what´s going on.I checked to see if it detected my drive and it appears to be detected as SATA 1 or something.Master and Slave say nothing is installed.I tried changing the boot order but i doesn´t seems to change anything. Gonna try tomorrow booting with the Data Lifeguard Tools form a floppy disk.But first i would love to have some kind of advice first because my Pc case is a bit small( microatx) and i have to remove my dvd drive and videocard to reach the Hardrive. Thanks for the help and sorry for my bad english and poor grammar.
