I want to add a second drive to my system and combine it with the original drive in a RAID 1. The original drive is the boot drive. With any normal RAID chip, I expect this would go something like entering the RAID bios and selecting the option to create a new Logical Drive. The RAID bios would ask me which is the source and which is the new drive. Then it would do the copying and I'd have a RAID 1 logical drive that is an exact copy of the original drive. However, I'm running a Biostar TA790GX A2+ with the SB750 southbridge. The RAID bios does not ask me which is the source/target drive and only warns me that the data will be deleted off the drives (which I don't think is actually true if you set initialization to "N"). In fact, the RAID bios is quite basic and most operations need to be completed through the Windows browser-based (who makes a browser-based RAID utility?!) RAIDXpert utility. Anyway, does anyone know how to add a drive and have it combined with the original drive using the RAID functions of the AMD SB750? digression: is it just me, or is the AMD RAID setup terribly designed? Thanks for any help.
