After we add a new drive, or a RAID set, My Computer should not show it. Here's why. Because there is no file system on said drive or array, My Computer has no reason to show the drive or array.
Did you try Disk Management to create a volume, partition then format that new volume?
This is my second DIY computer build. I've got a Gigabyte M68M-s2p motherboard with an AMD 840 quad core processor 4 GB ram, Segate Momentus Hybrid drive 2 Western Digital 1.5 TB HDD that I want to set up in a RAID 1 configuration and a LG blueray Rewitable drive. Hooked up everything, except the 2 western drives, installed operating system, Windows 7 Home Premium 64-bit OEM, booted it up and after a few tries, got everything working.
Now my problem. I went to install the 2 WD drives followed the manual on how you're suppose to set up the RAID in the BIOS, I got that working. I booted it up again and went to 'My Computer' and I don't see my RAID. I see my hard drive where I put my OS, I see my optical, I even see the little Iomega ext HDD I hooked up just in case but I don't see my RAID drives.
The motherboard manual gave instructions on how to set up the RAID for the OS( which I don't want, thats why I got the Momentus Hybrid for my OS) and says you have to configure it when you install your OS. It dosen't give any tips or suggestions for installing one after. Same with the website. So I'm looking for any help or if anyones had this same kind of problem and how they resolved it.
