By default the WAE 512 ships with 2 X 250 GB HDD in a RAID 1 disk array. If you are replacing only one disk the RAID should rebuild when the disk is replaced.
If you are replacing both disks, you will need to rebuild using the recovery CD.
Thaks for your Reply. I need to chance both disk. So, When I made the change I need to Use de Recovery Disck and choose the option 7. (Erase data and rebuild the RAID). Every works so good!
thanks
