+### Understand the alert
+
+This alert indicates that one or more physical disks attached to the MegaCLI controller are experiencing predictive failures. A predictive failure is a warning that a hard disk may fail in the near future, even if it's still working normally. The failure prediction relies on the self-monitoring and analysis technology (S.M.A.R.T.) built into the disk drive.
+
+### Troubleshoot the alert
+
+**Make sure you have taken necessary backup steps before performing any action. Netdata is not liable for any loss or corruption of data, databases, or software.**
+
+1. Identify the problematic drives:
+
+   Use the following command to gather information about your virtual drives in all adapters:
+
+   ```
+   megacli –LDInfo -Lall -aALL
+   ```
+
+2. Determine the virtual drive and adapter reporting media errors.
+
+3. Consult the MegaRAID SAS Software User Guide [1]:
+
+   1. Refer to Section 2.1.16 to check for issues with your drives.
+   2. Refer to Section 7.18 to perform any appropriate actions on drives. Focus on Sections 7.18.2, 7.18.6, 7.18.7, 7.18.8, 7.18.11, and 7.18.14.
+
+4. Consider replacing the problematic disk(s) to prevent imminent failures and potential data loss.
