⭐⭐⭐⭐⭐ In this video, we demonstrate the process of recovering data from a RAID 5 array on a Synology DS409 NAS in the macOS Sonoma 14.5 environment. We will cover cases of logical damage, specifically accidental deletion of files or folders and volume formatting. You will learn how to proceed if the NAS or a specific disk fails, as well as how to access data if the RAID drive is lost and network folders no longer appear. We also specifically show how to recover information after deleting a virtual LUN disk within the DiskStation Manager environment.
