Static Volume Recovery

Recovery Tool for Single / RAID 1 static volume

Please use this guide if you need to read the data of a Single Disk or RAID 1 static volume in a PC.

This guide is only intended for recovery of the data in case of the NAS being non-operational.

IMPORTANT NOTICES

• This tool is for recovering data from a Single or RAID1 static volume when the NAS unit is non-operational
• This tool will mount the data in READ-ONLY mode, to prevent accidental data corruption
• This tool is used entirely at your own risk and QNAP does not take responsibilty for any adverse consequences of using this tool
• Legacy volume or Storage Pool cannot be recovered with this tool
  • For Legacy volume (Single or RAID1) you can use EXT driver for Windows to read data directly in a PC: http://www.pendrivelinux.com/access-ext2-and-ext3-from-windows/
  • For Storage Pool, you must recover the volume in a QNAP NAS.
• This tool will not recover from faulty RAID array, filesystem errors, or deleted files

Requirements for recovery

• A Windows PC
• HDD from a QNAP NAS which contained Single or RAID1 static volume
• External USB HDD enclosure (installed with the HDD from a QNAP NAS)
• The network should have a DHCP server (most home routers have this built-in, if you don't know what this is don't worry about it)

Steps to recover

1. Download and install VMWare Player: http://www.vmware.com/products/player
   
2. Download the recover tool: http://download.qnap.com/Storage/tsd/utility/core.zip
   
3. Unzip the core.zip file
     
   
4. Connect the USB HDD enclosure to the PC
   Important!: If Windows asks to format/initialise the disk, select Cancel/NO
     
   
5. Open the VMware Player application which was installed in Step 1
   
6. Click "Open a Virtual Machine"
     
   
   
7. Browse to the unzip location of Step 3 and select the "core.vmx" file
   
8. Click "Play virtual machine"
   
   Note: If a prompt about virtual machine being moved or copied will appear, click "I copied it"
     
   
   Note: If a prompt about VMware Tools appears, click "Remind Me Later"
     
   
9. In the VMware Player menu bar, click Player > Removable Devices > USB Device > Connect to connect the USB HDD enclosure to the Virtual Machine
     
   
   Click OK, to confirm unplug from physical host and plugin to virtual machine

   Note: If you only see a "Disconnect" button, it means the USB device is already connected to the Virtual Machine
     
   
   
10. Press <Enter> at the boot screen
      
    
11. After you see a prompt "tc@box:~$", type the below command to run the recover script:
    sudo /mnt/sda1/recover.sh
    
12. If the script is successful, it will display an IP address
      
    
    
13. From the Windows PC, open Windows Explorer and type \\ip-address in the address bar, where "ip-address" is the address displayed in the previous step
      
    
14. You will see a folder "data" which contains the recovered data volume
    
    

Note:

• If necessary to reset the VM, type the below command:
  sudo reboot
