<div class="Body"><a name="1197691">For any RAID type, the most likely cause of the error is a grown defect in the </a>drive. For out-of-synchronization mirrors or parity, the error could be caused by improper shutdown of the unit. This possibility applies to RAID 1, 5, 6, 10, and 50. </div>

<div class="Body"><a name="1198059">When a verify fails, redundant units will automatically resynchronize user </a>data through a background initialization. The initialize will not erase user data, but will recalculate and rewrite user parity data. </div>
<div class="Body"><a name="1201000">If the unit was non-redundant, any data in the error location is lost. (However, </a>the error could be in a part of the drive that did not contain data.) A unit file system check is recommended.</div>

<div class="Body"><a name="1198799">The resynchronization of data that takes place during a background </a>initialization can slow down access to the unit. Once initialization has begun, it cannot be canceled. You can pause it, however, by scheduling it to take place during off-hours. For more information, see <a href="Maintain_Units.7.26.html#1112466">Scheduling Background Tasks</a>. You can also set the initialization process to go slower and use fewer system resources.
