I have a home PC with two identical physical drives (SATA), ASUS P5Q-EM motherboard and Windows 7. HDD 1 has two partitions C: and D:, Windows is installed on C: and everthing else is on D:.

Now the task is to organize some kind of RAID to mirror all data from HDD 1 to HDD 2 (at the moment HDD 2 is empty, no partitions), so HDD 2 is a backup copy of HDD 1.

I've never had chance before to work with RAID, so any suggestions would be greatly appreciated.

Whatever you choose to do, I'd advise against using any RAID that comes from the motherboard. –  Bart Silverstrim Apr 27 '10 at 21:28

RAID is not a Backup. If you want a backup try using Windows Backup.

If you want a duplicate drive in case one drive fails, then you want RAID. Firs tyou have to figure out what kind of RAID setup you want, but it sounds like you want a mirror (RAID-1).

The quick directions to setup a mirror: Open Computer management, Storage->Disk management. Right click "Disk 0" and Convert to Dynamic. Do the same for the other disk. Right click your "C:" dirve and click "Add Mirror", follow the directions. It will take a little while to fully synch, but you can use the computer while it's working.
