Receiving a critical warning for your storage device is a serious matter that demands immediate attention to prevent potential data loss and system instability. This article provides a comprehensive guide on understanding these warnings, the types of alerts you might encounter, and the steps you should take to safeguard your data and maintain system performance.

Understanding Critical Storage Warnings​

Windows operating systems are equipped with monitoring tools designed to detect hardware abnormalities in storage devices, particularly Non-Volatile Memory Express (NVMe) Solid State Drives (SSDs). When such anomalies are detected, the system issues a critical warning to alert the user of potential issues that could lead to device failure. These warnings are crucial as they provide an opportunity to address problems before they escalate into complete hardware failure.

Types of Critical Warnings​

There are three primary types of critical warnings that Windows may display concerning your storage device:

• Spare Capacity is Low: This warning indicates that the spare storage capacity of your SSD has fallen below the manufacturer's recommended safety threshold. Spare capacity is essential for the SSD to manage data efficiently and maintain performance.
• Reliability is Degraded: This alert signifies that the reliability of your SSD is compromised due to significant media-related errors or an internal error within the NVMe subsystem. Such degradation can lead to increased error rates and potential data corruption.
• Drive is Set to Read-Only: In this scenario, the SSD has been set to a read-only state, meaning you can access and read data stored on the device, but you cannot write new data to it. This state is often a protective measure to prevent further damage or data loss.

Key Disk Health Attributes​

In addition to the critical warnings, Windows monitors several disk health attributes that can provide insight into the overall health and performance of your SSD:

• Estimated Remaining Life: This metric provides an approximate percentage of the SSD's lifespan that has been used, based on the manufacturer's predictions. It's important to note that while the value is capped at 0%, consumption below this threshold does not automatically indicate device failure.
• Available Spare: This attribute reflects the normalized percentage (ranging from 0% to 100%) of the remaining spare capacity available on the SSD. Adequate spare capacity is vital for the SSD's wear leveling and error correction processes.
• Temperature: Monitoring the temperature of your SSD is crucial, as excessive heat can accelerate wear and lead to premature failure. The temperature is typically measured in degrees Celsius.
