A new client has a two-drive NAS that shows 878 of capacity with 60% utilization. While troubleshooting an issue for the client, a technician notices the NFS folders are empty. Upon further…

There is no information to suggest the RAID card is damaged; the issue directly follows a configuration change, implying a logical rather than hardware problem.

Media failure refers to a physical issue with a hard drive, but both drives are implied to be operational given the capacity is shown and the issue arose after a configuration change.

When a RAID configuration is changed, especially from a striped array (RAID 0) to a mirrored array (RAID 1), the RAID controller typically performs an array rebuild or reinitialization. This process often reinitializes the disks, leading to the loss of all previous data and empty folders.
