5. When you are finished, press Done (as the screen shown below).
Notes:
1.Before adding a new drive to an array, back up any data contained on the new drive. Otherwise, all data will be lost.
2.If you stop the Build or Clear process on a RAID 1 from ACU, you can restart it by pressing Ctrl+R.
3.A RAID 1 created using the Quick Init option may return some data mis- compares if you later run a consistency check. This is normal and is not a cause for concern.
4.The ACU allows you to use drives of different sizes in a
RAID . However, during a build operation, only the smaller drive can be selected as the source or first drive.
5.When migrating from single volume to RAID 0, migrating from a larger drive to a smaller drive is allowed. However, the destination drive must be at least half the capacity of the source drive.
6.Adaptec does not recommend that you migrate or build an array on Windows dynamic disks (volumes), as it will result in data loss.
Warning: Do not interrupt the creation of a RAID 0 using the Migrate option. If you do, you will not be able to restart, or to recover the data
that was on the source drive.
