I am only too happy to report a successful recovery of ALL of my data from my Synology box using my PC!
Situation: Distinctly Unpleasant
My CS-407 died (it wasn't it's fault but I won't go into it now). The motherboard was roasted through the USB port in the middle of re-constructing a failed Drive 3. 4X500GB RAID, 700GB of data, 40GB not backed up to secondary storage.
-No way to buy another Synology product (I live in Moscow, Russia).
-Don't know if the drives are burned out or not
-No backup of my CS-407 for the last week
On hand: One PC with 4 sata ports
-Need a way to do a non-destructive read of the Linux EXT/2 EXT/3 broken RAID
Software required: UFS.Explorer Professional Recovery v 3.9.1 ~$80US (http://www.ufsexplorer.com
Procedure I followed:
-Attached the 3 drives to my PC
-Run UFS Explorer
-Command: Build Software RAID
-Figure out the EXACT order originally from the Synology CS-407 through trial and error. Settings: 64K, Left-Symmetrical, 4 drives, use a "Broken Placeholder" for the missing drive. Build the software RAID by identifying and putting in the correct order.
-UFS Explorer immediately detected the Linux partition (after my 10th iteration) and gave me FULL access to ORIGINAL file structure. I was able to copy any files and/or directories at near hard drive speeds.
For example, my Synology hard drives that worked were numbers 1,2,4. I plugged them into various sata ports on my computer and discovered that I had 6 hard drives (3 Synology drives and 3 of my normal drives). Each of the synology drives were formatted into 3 partitions. The 3rd partition is the RAID data storage. My magic combination was "2, 5, BPH (Broken Place Holder),3". I went through "2,5,bph,3", "2,3,bph,5" etc. etc.
Obviously, your configuration will be different!
