In this article I will try to tell in detail about the procedure for creating software RAID in Windows 7. So, we have
1) PC running Windows 7 Professional – 1 pc
2) SATA 2 TB hard drive – 2 pcs
What we want to get: the output we should get a system in which important information is protected from damage to the hard disk using RAID 1 technology (mirroring).
How to create software RAID
Both hard drives must be installed in the computer and initialized. The initialization window should appear when you first boot your computer, otherwise you can initialize them using the Logical Disk Manager.

Now we are going to “My Computer” and see that a new disk has appeared with a drive letter M :. In fact, this is a virtual disk that physically represents 2 disks. Now, any information recorded on the M: drive will be protected from the failure of either of the two hard drives.
