Adaptec SATA RAID Utility for Intel ICH5R
4. Create RAID via allows you to select between the different creation methods
for RAID 0 and RAID 1. The following table gives examples of when each is
appropriate.
Notes:
Before adding a new drive to an array, back up any data contained on the
new drive. Otherwise, all data will be lost.
If you stop the Build or Clear process on a RAID 1 from ACU you can only
restart it from Adaptec Storage Manager - Browser Edition. (See Chapter
4 for details.)
A RAID 1 created using the Quick Init option may return some data
miscompares if you later run a consistency check. This is normal and is
not a cause for concern.
The ACU allows you to use drives of different sizes in a RAID 1. During a
build operation however, only the smaller drive can be selected as the
source or first drive.
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.
Adaptec does not recommend that you migrate or build an array on Win-
dows dynamic disks (volumes), as it will result in data loss.
5. When you are finished, press Done.
MSI Reminds You...
Do not interrupt the creation of a RAID 0 using the Migrate option. If you
do, there is no way to restart, and no way to recover the data that was on
the source drive.
