Currently I’m running only 1 hard disk in my pc. Now I decided to install a second drive and to set my disks up in a RAID 1 configuration to prevent data loss. Here’s how I did it.
- I bought a second drive which resembles the first drive. In my case another 1GB Western Digital Green which is know for low energy usage and low noise.
- I converted my first drive to a Dynamic Disk through the Windows Disk Management tool. This can only be done after you installed Windows 7. This activity took approximately 1 second.
- I shut down the PC and physically installed the extra hard drive.
- In the Windows Disk Management tool I ignored the proposal to have it initialised.
- I selected the old Disk in the Windows Disk Management tool and chose it to be mirrored by the new disk.
- It then started synchronising and indicated so in the status.
Here’s an overview of the various RAID configuration being supported or not in the different Windows 7 versions. Thanks to Alan.
Raid 0 (Spanning/Stripped) is supported in every Windows 7 version (Beta/RC and RTM/Final) using software raid
Raid 1 (Mirror) is supported in Windows 7 Professional, Enterprise, and Ultimate (Beta/RC and RTM/Final) using software raid
Raid 5 is not support in Windows 7 (Beta/RC and RTM/Final) using software raid. You will need to use hardware (ie, a raid controller) or use a server operating system for Software raid.
