I have a windows server 2008, and 2 hard drive which set as RAID 1, now the primary hard drive report some error and have to change. I have backup of major data but I have many setting on it's IIS and DNS server which I can't get backup from there. Is it secure that I change the primary hard drive without data lost? if I install a new hard, it will be re sync again?

In a RAID 1 configuration, you should be able to change either drive and the array will rebuild. You may need to initiate the rebuild from the software manager app.
