Western Digital manufactures desktop edition hard drives and RAID Edition hard drives. Each type of hard drive is designed to work specifically in either a desktop computer environment or a demanding enterprise environment.
If you install and use a desktop edition hard drive connected to a RAID controller, the drive may not work correctly unless jointly qualified by an enterprise OEM. This is caused by the normal error recovery procedure that a desktop edition hard drive uses.
When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover…
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…

Please Note: Depending on how the WD ShareSpace RAID is setup, that RAID array may not be recoverable from a drive failure.
Qty of 2 – 1TB internal hard drives:
- RAID-0 – 2TB – (Not recoverable)
- RAID-1 – 1TB – (Recoverable)
- RAID-5 – (Not Supported)
Qty of 3 – 1TB internal hard drives:
- Spanning – 3TB – (Non recoverable)
- RAID-0 – 3TB – (Non recoverable)
- RAID-1 – (Not Supported)…
Advantages of RAID
RAID is an acronym for Redundant Array of independent Disks. With RAID enabled on a storage system you can connect two or more drives in the system so that they act like one big fast drive or set them up so that one drive in the system is used to automatically and instantaneously duplicate (or mirror) your data for real-time backup.
There are three reasons you might want a RAID system of drives.
- You need tons of storage space and you need it to be fast. (RAID 0)
- You want to instantaneously and automatically backup your data. (RAID 1)
- You want both. (RAID 5)
Which…
!!WARNING!!
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. Though this firmware upgrade to your product is a change to the product the terms and conditions of your Seagate warranty for the product will remain effective to its normal expiration.

The NAS 4000 Series has a software controlled RAID 5 disk array, Dual 10/100 NIC’s, and two independent, mirrored Operating Systems.
Identifying hard drive failures and RAID regeneration times for the NAS 4100.
Overview: The NAS 4100 comes with 4 separate hard drives. In the event of a hard drive failure you will be notified via an Email alert and/or Web UI. RAID regeneration can take up to 30 minutes depending on which drive has failed.
To check status of your NAS 4100 drives use Logical Disk Manager. To access the Disk Management utility:
- Open “MaxNeighborhood” and double-click on the NAS 4100 that you want to create the folder on.
- Login to NAS 4100 with the appropriate Administrator (or Administrator equivalent) username and password.
- Click on "Administer…
