Problem:
Changing from RAID-0 to RAID-1 on a My Book Studio II under Windows XP SP3 connected via 1394a (FireWire 400) fails to complete. Disk Management cannot be opened, and Cannot restart as well (Windows Freeze).
Cause:
The cause of this issue is unknown.
Resolution:
To resolve this issue, please connect the My Book Studio II via USB or 1394b (FireWire800) and perform the RAID change again.
Problem:
Attaching another drive while doing a RAID change can reformat the second drive.
Cause:
If the second drive is assigned the same unix device name that was assigned to the RAID device before it was dismounted from the system, the second drive will be reformatted.
Solution:
External drives should not be removed or attached during a RAID change operation.
If a single hard drive fails while the WD My Book World (Blue Rings) storage system is operating under RAID-1 mode, the data on the storage system will still be saved and accessible on the properly working hard drive.
Dismantle the unit and replace the faulty hard drive. Once the hard drive has been physically replaced and the unit has been reassembled, please follow the directions below to format and mirror the existing data to the new replacement hard drive.
Ensure that the WD My Book World (Blue Rings) storage system is powered on and is detected by WD Anywhere Access…
RAID (redundant array of independent disks) is a method of using multiple hard disk drives to act as one. RAID is used to increase hard drive speed and storage capacity, prevent data loss in the event that one of the disks in the array physically fails, or both. As far as the operating system concerned, a RAID array will appear to be a single logical drive. RAID uses a method called striping in which the drives are broken down into small partitions. These partitions, called stripes, are distributed such that each successive stripe is on a different drive.
Important: There are many different…
