Scenario

Take one HDD from NSA RAID1 and connect it to a PC with Linux.
How to see data from NSA on this HDD?

Step

This is an example:

 

Step 1: Power off your PC.

Step 2: Install your HDD(s) and make sure all HDD(s) installed on the PC come from NAS

Step 3: Boot up with DVD-ROM ubuntu-10.04-desktop-i386.iso.

Step 4: Choose "Try Ubuntu 10.04 LTS" in the main menu.

Step 5: Choose Application->Accessories->Terminal to open a Terminal

Step 6: Run commands in terminal.

#change user to root
sudo su
#make sure your HDD appear in the system
fdisk -l
#install mdadm, if it asked you about Posifix Configuration, choose "No configuration"
apt-get install mdadm
#assemble your HDD: JBOD, degraded RAID1
mdadm -A -f /dev/md0 /dev/sda2
#assemble your HDD: healthy RAID1
mdadm -A -f /dev/md0 /dev/sda2 /dev/sdb2
#check the result
cat /proc/mdstat
#mount your device
mount /dev/md0 /mnt
#see your data
ls /mnt/
