Method 2. Recover Data from Synology NAS by Taking Out Disks and Rebuilding RAID (Complex)
Unlike EaseUS NAS data recovery software, other NAS recovery products currently on the market only allow you to retrieve data in a very complex way, which can be tricky for average users.
The traditional procedures for Synology NAS data recovery are as follows:
Step 1. Power off the NAS service. Remove the RAID drives disks one by one.
- When you take disks out of the NAS, we highly suggest that you label them based on which bay they belong to. These marks will help you put them back together in the same correct way. Besides, when you remove the NAS drives, do not violate the warranty.
Step 2. Connect the drives to your computer. You can use SATA cables to connect the disk directly to your PC's motherboard or use USB-to-SATA adapters together with power. Do not initialize or format the drives when you are asked.
Step 3. Prepare enough external/internal hard drive or another network storage space (equivalent or more than the volume of recovered data from failed NAS drives) to keep the restored data from NAS.
Step 4. Get and use one of the best NAS recovery software to get data off.
