I am having an issue with a Dell XPS 710 that I thought was configured with a RAID 0 array using two 150 GB hard drives. Please understand that I am working with a limited amount of technical knowledge when it comes to hardware issues.
My first indication of trouble began when my C drive began to reach full capacity. I began moving data to D drive, but finally reached a point where my boot drive was full. At that point I cloned all my C drive files to a 300 GB hard drive thinking I could simply exchange the drives. I soon discovered that my new C drive indicated a total capacity of 150 GB. While reading the Owner's Manual (which left me more confused than when I began) I thought the two hard drives had to have the same capacity, so I cloned and installed a second 300 GB hard drive. The second hard drive (D) correctly shows 300 GB but my boot drive still indicates a capacity of 150 GB.
I tried turning off RAID but upon restart I got a message saying it couldn't access C drive.
Question: Can someone walk me through the process of removing the RAID array completely so I can use both hard drives to full capacity?
