Description
One of the drive bays in a multi-bay My Cloud device displays a Red LED. The Dashboard indicates that the drive has failed. One of the internal drives in the device has failed and needs to be replaced.
Resolution
This drive should be replaced as soon as possible.
For maximum data protection, it is recommended that the Cloud Storage device is turned off. On the Dashboard, go to Settings then Utilities and click on Shutdown. Once the device is off, keep it that way until the failed hard drive has been replaced. The drive must be replaced with a drive of identical capacity and rating when used in a RAID environment.
What to expect from a drive failure varies depending on the RAID mode in which the My Cloud Mirror, EX2, or EX4 is set to. For more information, please follow the information listed below:
IMPORTANT:- 4k drives are not supported in My Cloud enclosures and should not be used.
- Certain RAID modes retain data accessibility after a single drive failure has occurred. However, Western Digital still recommends to turn the My Cloud Mirror, EX2 or EX4 off unless extremely necessary. While missing a drive, the redundancy of the RAID array is compromised. Turn the unit off to avoid data loss in the rare case that a second drive were to fail.
Critical: On RAID modes that lack redundancy (such as RAID 0, Spanning, or JBOD). If no backup of the data exists, recovering data located on failed drives may still be possible through Data Recovery. Contact a Data Recovery service prior to replacing the failed drive. For more information on Data Recovery, please see Answer ID 6624: Recover Data from a Drive, Obtain a Circuit Board, Repair a Drive, or Find Data Recovery Partners |

Two Bay Drive Replacement Instructions
While handling an internal drive, ground yourself by touching metal before handling the device, to avoid electrostatic discharge (ESD) issues. Please see Answer ID: 1486 - How to properly handle Western Digital internal hard drives for more information. |
Removing a Drive:
Please follow the steps outlined below for removing the faulty drive from the enclosure:
- Place the powered off unit, with the Ethernet and Power cable disconnected, on a clean and stable surface
- Reveal the hard drives by pressing the indented button on the top of the device and pulling up the door
- Remove the bracket used for holding drives in.
- Pull the plastic tab at the back of the drive, while guiding the drive up and out of the enclosure
Preparing a Drive:
The My Cloud device ships with a bag holding the screws, tabs, and labels needed for inserting the new drive. For WD replacement drives, the parts attached to the faulty drive can be reused. A standard phillips-head screwdriver is all that is required to perform this task.
- Using a screw from the bag, attach a plastic tab to the top hole in the drive's side.
- Attach a screw to the corresponding hole on the other side of the drive.
- Attach label 1 or 2 to the top of the drive. Label 1 is on the left while label 2 is on the right, when looking down on the top when facing the front of the unit. There are corresponding numbers on the cross brace label.
Inserting a New Drive:
Once the drive is prepared to be placed into the My Cloud device, proceed to insert the drive:
- Press the indent on the top of the unit to open the door, and then remove the bracket that holds the drives in
- When looking down on the top of the unit with it facing inwards, and inserting two drives, arrange them so that the connectors at the bottom face in, the green boards facing each other. If inserting only one drive, the green board faces the middle of the unit
- Gently slip a drive into the slot. Make sure the plastic tab is sticking up at the back of the unit. Repeat with the other drive, if applicable
- Screw the bracket over the tops of the drives. Close the door and firmly push down until it locks into place
- Reconnect the network and power cables of the device
- Power-On the unit. Allow the unit to fully boot-up; this may take several minutes. It is normal to see a red LED because the replacement drive has not yet be prepared for use by either rebuilding the RAID array or formatting and creating a new volume. Proceed to the 'What to expect' section below related to the specific RAID configuration used prior to the drive failure for next steps
What to expect if a drive fails:
- What to expect if a drive fails on a RAID 0
- What to expect if a drive fails on a RAID 1
- What to expect if a drive fails on a Spanned volume
- What to expect if a drive fails on a JBOD setup
Replacing a drive on a RAID 0
RAID 0 stripes data across all drives involved in the RAID to provide improved performance, but does not provide any level of redundancy.It is normal to see a Red LED representing the existing and the replacement hard drive because the RAID is degraded.. Please see Answer ID: 13175 - The front LED on a My Cloud Mirror or My Cloud EX2 displays solid red for more information. Please follow the steps outlined below to prepare the replacement drive and create a new RAID0 array:
- Open the dashboard. Please see Answer ID 27432: How to Access the Dashboard on a My Cloud Device for help with this
- Click the Alert Icon to confirm the Volume Failure
- Additionally, Click the Storage Icon to view the RAID Health to confirm No Configured Volumes

Replacing a drive on a Spanned Volume
When a My Cloud 2-Bay NAS has a volume set to Spanning, both drives in the array work together to create a single large volume. Data that is transferred to the device fills up one drive at a time, filling the next in line once the previous becomes full. When a drive fails, the volume is no longer accessible from the network drive. It is important to know Spanned Volumes do not have redundancy and therefore any attempt to recover the data must be accomplished before attempting to rebuild the array. To replace the failed drive, follow the steps below:
- It is recommended turning-Off the My Cloud as soon as the RAID is found to be degraded to avoid further loss of data. Leave the device off until a replacement drive is inserted into the failed drive's drive bay
- Replace the failed drive. For assistance replacing the failed drive, please see Answer ID 10336: Steps to Get a Warranty Replacement, Power Supply, or USB Cable
