The Product I have is a Western Digital My Book

The device has stopped working but there is nothing wrong with either of the two mirrored drives. I would like to take out the two mirrored hard drives, and recover the data if at all possible. How would I go about this on ubuntu 11.10? Both of the drives are recognized but I can not see the data anywhere. The relevant software I have on the system are: Disk Utility and a terminal application called mdadm. I am trying to be cautious and not accidentally wipe the data. Any help will be much appreciated.


If you can take out the drive and connected in a different way then you should be able to do:

sudo mount /dev/sdb1 /mnt

Before doing that I would suggest disconnecting the second drive also.


maybe ubuntu allready automounted the devices. you can check that with

cat /proc/mdstat

or by looking for assembles md's:

ls /dev/md*

if that did not work it depends a bit on how the drives are aligned, but

sudo mdadm --assemble /dev/md0 /dev/sda /dev/sdb

should assemble the raid device, and it shouldn't break anything it it doesn't. whereas /dev/md0 is the ID of the raid device you are creating (you can leave it like this if there are no other raid devices in your system). you just have to exchange /dev/sda and /dev/sdb with you hdds or partitions (you can raid full hdds or just single partitions). afterwards you can mount the device with

sudo mount /dev/md0 /mount/point

good luck
