LSI MegaRAID SAS 9260-4. I have 14 3TB SATA drives configured in 1 big RAID 5 volume. 1 physical drive is showing in MegaRAID as failed and 1 other is showing as unconfigured. In Windows Server 2012, the drive doesn't show up in file explorer anymore. Disk Management in Server 2012 shows the disk as unknown, not initialized. What steps should I take to correct this issue? Will I lose data?
