Method 3: Synology Data Recovery Using Reclaime (Disk Pull-Out Required)

The Synology NAS data recovery process of ReclaiMe File Recovery software is relatively more complicated than Wondershare Recoverit, because you must remove the hard drives from the Synology Server first. But it does its work.

You can effectively restore the disk order, block size, start offset, and other RAID configuration parameters from the unplugged Synology NAS drive with ReclaiMe File Recovery.

Follow the steps below to recover your deleted files from Synology NAS using ReclaiMe:

After disassembling the NAS server,

Step 1: Pull out the hard drives from Synology NAS and connect them to your Windows PC. Remember to switch off the power when disconnecting and connecting the hard drives. Label each disk with the section it belongs in before removing them from the Synology NAS. These labels will help you similarly reassemble everything if necessary. Refuse any requests from Windows on the computer to which you have connected the disks to "Initialize disks" or even "Format" them.

Step 2. Launch ReclaiMe File Recovery. Most NASes use MD-Raid or LVM drivers to manage an array. ReclaiMe can break the MD-Raid and LVM control structures.
