How do I change the RAID level of a My Book Premium II, My Book Pro II, My Book Studio II, or My Book Mirror Edition external hard drive?
The My Book Premium II, My Book Pro II, and My Book Studio II external hard drives are pre-configured for RAID 0 (Striped) mode for maximum capacity and accelerated performance. These products also support RAID 1 (Mirrored) mode for data protection, which dedicates half the capacity to mirror the data in both internal hard drives.
The My Book Mirror Edition external hard drive is pre-configured for RAID 1 (Mirrored) mode for maximum data protection. This drive…
All WD ShareSpace drives support Spanning, RAID-0 (Striping), RAID-1 (Mirroring), and RAID-5 (Redundancy with parity). Each RAID mode may or may not be available for usage based upon how many internal hard drives are installed in the enclosure.
Please Note: Based upon how the WD ShareSpace RAID is setup, the WD ShareSpace will show different available capacities:
Qty of 2 – 1TB internal hard drives:
- Spanning – 2TB
- RAID-0 – 2TB
- RAID-1 – 1TB
- RAID-5 – Not Supported
Qty of 3 – 1TB internal hard drives:
- Spanning – 3TB
- RAID-0 – 3TB
- RAID-1 – Not Supported
- RAID-5 – 2TB
Qty of 4 – 1TB internal hard drives:
- Spanning – 4TB
- RAID-0 – 4TB
- RAID-1 – Not Supported
- RAID-5 –…
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.
Note: A RAID 1 array is designed for fault tolerance. You will not notice any performance increase in your computer after creating a RAID 1 array. A RAID 1 array uses the second hard drive to copy the data of the first drive. Should one of the hard drives fail, you will still be able to boot your computer using the second hard drive.
Important: After creating a RAID 1 array, the total capacity of both hard drives will not appear as usable space in Windows. Because the second hard drive is being used to store the exact same data of the first drive,…
Note: A RAID 0 array is not fault tolerant. It is recommended that you backup any important data that you decide to store on the array.
To create a RAID 0 array please follow the steps below:
- With the computer powered off, follow the instructions for installing the RAID controller correctly and connect both Serial ATA hard drives to the controller.
- Boot your computer with the controller and drives already installed.
- Watch your boot screens for a prompt that will ask you to press the Control and F keys at the same time to enter the Fastbuild utility and press those keys to enter.
- Press the 1 key to enter…

If the firmware upgrade installation instructions are not followed properly the firmware upgrade could be data destructive and/or render your hard drive inoperable. As Seagate does not warrant the data on your drive, in addition to regular back-ups, if possible your data should be backed up before upgrading the drive firmware. Additional information on backing-up the contents of your drive can be found at www.seagate.com.

Overview: The standard configuration for a NAS 6000 base unit includes two user volumes, each supporting up to 960GB of raw storage capacity for a total of 1.9TB. In a RAID 5 configuration, the usable capacity is 723 GB on the first volume and 768 GB on the second. This document describes the optimal way to reconfigure this user space into a single 1.5 TB user volume (base unit only), or up to a 4.43 TB user volume on a fully configured MaxAttach NAS 6000 (base unit plus two expansion units).
The NAS 6000 base unit contains twelve 160GB hard disks. This…
