How to Determine if you Have a Failed Storage Drive?
This article goes over how to determine if a storage drive has failed. To replace a storage drive, refer to Knowledge Base article: "How to Replace a Failed Storage Drive"
How do You Know if You Have a Failed Storage Drive?
There are typically two main signs that you may have an issue with one of your storage drives. The first is the red banner notification you’ll see when connecting to your NVR with one of a few error messages about a storage drive. The second, the unit is stuck loading indefinitely with a status at the top right that mentions FSCK.

If the unit can boot, you’re going to want to check the Storage tab in System Settings to see what’s going on with the storage drive. If you find it missing, then you may have an issue with the storage drive.
(Notice: This does not pertain to RAID units. Refer to either of the following for troubleshooting a drive failure in a RAID set: Raid Maintenance (Linux OS) - OpenEye Knowledge Base or RAID Maintenance (Windows OS) - OpenEye Knowledge Base)
Troubleshooting
Power down the NVR and disconnect the power cable. Open up the NVR’s enclosure and ensure the drive is correctly connected and seated. Once verified, hold down the power button on the unit for about 30 seconds while you have the power disconnected (if the unit has a power switch instead of a button, just ensure it’s in the on position for 30 seconds) to perform a power drain. How to Perform a Power Drain
Once the power drain is complete, power the unit up. If the unit is still stuck booting while running service FSCK, or the storage drive is still missing, you may have a failed storage drive. At that point, contact Technical Support to start the RMA process: RMA Billing, Types, and Processing Portal, or run through more troubleshooting if an easier solution is suspected.
