Dumas, who has excellent mechanical aptitude, owns a computer with two hard drives. One drive is used for the operating system and the other drive is used for his personal files. He decides to install a third disk in a RAID 1 configuration to protect the disk with his files against data loss. He is not too concerned about data loss on the disk with the operating system because he could easily reinstall the OS, so that disk is not included in the RAID configuration. When he is done, he powers up his computer, no error messages are displayed, yet he is distraught because all his data is lost. Why would this happen?

The new drive was smaller than the original drive so the data from the original did not fit.

Since the new drive had no data, and RAID 1 mirrors data, it erased the data on the original.

The RAID expansion card is not seated properly so the RAID drives are not being detected.

During routine maintenance on your server, you discover that one of the hard drives on your RAID array is starting to go bad. After you replace the drive and rebuild the data, you run diagnostics on the RAID controller card with no problems, so you believe you fixed the problem. The next morning you arrive at work and discover that the RAID has completely failed. None of the disks are working. Your server is still running because you installed the OS on a non-RAID disk, but all the data is missing, and the server shows that none of your RAID disks are found. What might be the problem with your server? (Select all that apply.)
