May you worry loss all of your data if there is a physical failure on your hard drive? In Windows 7 Professional Edition and Ultimate Edition, you could consider using mirroring volume (RAID 1) for your important data. Mirrored volume is attractive feature of Windows 7 compared to earlier Windows XP and Vista.
Mirroring is implemented to fault tolerance. In a mirrored volume (it must consist of two disks), all of the data will be duplicated across two hard drives automatically, so if one of the drive dies, the data still can be accessed from another drive.
To set up a Mirrored Volume in Windows 7, here are steps.
Due to some other requirements, you may want to covert the dynamic disk to basic one. However, you will find the Windows 7 does not allow doing the operation unless you first delete the Mirrored Volume G:. For more information, please refer to "Convert Dynamic Disk to Basic with three ways". I recommend a dynamic disk conversion software - Aomei Dynamic Disk Converter. It can directly and safely convert mirrored volume disk to basic disk. Below is it’s a screen shot.
With windows disk management snap-in and the third-party tool help, all dynamic disks and dynamic volumes can be managed more effectively. You now can practice the mirrored volume (RAID 1) but note that it is unavailable under Windows 7 Home Edition operating system.
