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?
O The new drive was smaller than the original drive so the data from the original did not
fit.
O He didn't back up his data. When RAID is configured all data on participating drives is
lost.
O The RAID expansion card is not seated properly so the RAID drives are not being
detected.
Since the new drive had no data, and RAID 1 mirrors data, it erased the data on the
original.
