hello, Can anyone help? I just bought a WD SATA 320 gb HDD and am trying to install it as an extra storage space - not a boot disk. the problem is that my mobo (ASUS K8V SE Deluxe) has two raid controllers. One is a VIA that i have two HDD's plugged in and not set up as raid - the boot disk (maxtor) is attatched to the primary and the other (storage) is connected to the secondary, and everything works fine. the second Raid controller is the promise 378 fAST TRACK controller and this is the one that i am trying to attatch the new 320gb HDD. I have updated VIA drivers, mobo bios, fastrack driver (fine in system). But Windows does not trecognise the drive. If i put the promise controller as an 'ide connected device' in bios i can set the boot order and use my normal drive (VIA primary contoller - maxtor) which works fine but windows doesn't recognise the new WD drive plugged into the promise controller. But if i set the promise controller to 'RAID' in the bios and use the little prog to arrange the array, so it is recognised, the boot order changes and i cant access windows!! The bios recognises that there is a drive attatched to the promise fastrack controller and attempts to boot from that - but when i go into bios and attempt to change it back to the maxtor (VIA controller) there is no option to boot from the VIA Raid Controller - only the promise. This is doing my head in! Has anyone any ideas as to why this is happening or any reccomendations on how to install this new drive. Thanks for any help. Arggghhh.
