3ware Serial ATA RAID Controller User Guide
Action
When a verify fails, redundant units will automatically resynchronize user
data through a background initialization. The initialize will not erase user
data, but will recalculate and rewrite user parity data.
If the unit was non-redundant, any data in the error location is lost. (However,
the error could be in a part of the drive that did not contain data.) A unit file
system check is recommended.
Under Windows, right-click on your drive icon and choose
Properties>
Tools> Check Now
.
Under Linux or FreeBSD use
fsck /dev/sda1
. If you have more than one
SATA device, substitute the correct drive letter and partition number, such as
sdb2, for sda1.
The resynchronization of data that takes place during a background
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 “Scheduling Background
Tasks” on page 166. You can also set the initialization process to go slower
and use fewer system resources. For more information, see “Setting
Background Task Rate” on page 165. (Initialization occurs at the Rebuild
rate.)
