Hi, I have a Dell Precision 380 with 2 HD (160GB seagate & 250GB Maxtor - sata drives) that were in a RAID 1 (mirror) configuration. I wanted to upgrade the HD space so i popped out the 160GB drive and put in a 250GB drive. The computer started and rebuilt the RAID. I didn't realize that the RAID would still be only 160GB. So what do i do now
