I have winXP a system with a 150GB scsi drive, I want to replace it with 2 new 500GB SATA drives in Raid1. I want to clone the old drive onto the first partition of the new SATA RAID, and have a second partition with the remaining 350GB. The main issue is that I want to clone temporarily onto an external USB drive. Restore it onto the RAID drives while its installed in a separate computer. Test everything then swap the SCSI drives out for the RAID drives on the original system. I have a few questions regarding this process. 1) I have drivers for the promise raid controller, but I'm not sure where to put them. I read that I should "install" the drives before cloning the C:\ drive but I don't have an install option. I have the .inf, .cat, and .sys files but I'm not sure where to put them in order for windows to recognize the Raid controller once its cloned to a new system. I want to be able to boot off the new drives. 2) I am using a USB external 500GB drive as a temporary hold because I can't clone directly to the raid drives. I remember in the past having trouble with the acronis boot cd and detection of the USB drives. Can anyone give info on proper use of USB drives? Was I doing something wrong or is something wrong with my boot CD? 3) Is there anywhere I can go to get more detailed info on how to go about doing what I mentioned above?
