RAID1 with OS/Won't boot when other hdds are plugged in Tags: NAS / RAID SSD Storage Last response: July 11, 2012 10:01 PM in Storage Share nugunsknight July 11, 2012 9:17:20 PM I have some issues with a setup i am currently trying to upgrade. The specs are as follows. ASUStek M4A78T-E Mobo (x2) 120 OCZ SSD Raid1 With OS installed on. 16gb ram Then the issue comes in when i attempt to add additional HDDs (1 500GB and 1 1TB) Both of these are not raid drives, i have information located on these that i need to keep. Now i only have 5 sata ports. I still use an IDE dvd-rom, and one SATA port has a BD-rom. I finished the windows installation with just the two SSDs and after updates and drivers, i powered down and plugged in the two other drives. powered on. All i got was a black screen after all the post messages with the flashing cursor. Restarted. BIOS does not show any discs. restarted Booted into the raid utility, it sees all drives and has the 2 hdds as <single drive> and the two ssds as a functional raid 1 when i have just the two ssds plugged in, windows boots just fine. when i plug in the other two hdds, it will not boot. Any idea what may be happening? if you need anymore info, just let me know. thank you in advanced.
