I am trying to convert a Dell PowerEdge SC1420 from SBS 2003 to Windows. It boots fine to SBS using the original HardDrives (which I need to preserve), but will not recognize the replacement SATA HD's. Tried every possible BIOS combination without success. I suspect a problem with the embedded SATA RAID. It is a CERC SATA 2S. The SATA initial screen reports it loaded the controller configuration, but no logical drives found, and No Int 13 drives to support. Does the embedded SATA need to get drivers from the HD before the BIOS can recognize them? Thanks for any suggestions!
