I knoew this question probably came up before, but I could find the answer. I have two 1T HDD setup in RAID 0, but the motherboard went bad. I replaced the motherboard and installed Ubuntu 14 on a new drive. The two 1T HDD are connected in Sata port without using RAID in BIOS. I was hoping Ubuntu can see the RAID0 volume automatically, as some has mentioned on the Net, but I guess I wasn't oneof the lucky. Here's the info on the screen, and I would appreciate it if someone can help (sda is where Ubuntu is installed, sdb and sdc are the two disks in RAID0, sdc is a USB drive for data storage)

What REALLY matters is HOW you setup the RAID before? Was it a software RAID when you first installed Ubuntu or was it more of a Hardware (Its not really TURE Hardware RAID) RAID?
