The best I can explain this problem is as follows. I built a computer for my client that consisted of 2 500GB sata drives configured in RAID 1. The client has sensitive data that I wanted to ensure that they wouldn't lose if a bad hard drive would occur on a single disk system. When I first built the system it showed 1 500GB Partition like it should in RAID 1. A couple days ago the system had an error message about some problem with an array. This message popped up in Windows 7 after the system booted. When you go into computer it now shows 2 drives that have the same info on them. The main drive has current data but the second drive has data from a couple weeks ago. I am thinking the the array went down some how. How would I configure the RAID array again and write the current data on the secondary hard drive.
