How to get to your data
This is a quick step-by-step guide to getting to your 1TB of data when you really don't have any more choices.
- Either use your existing linux-box or get a bootable distribution image and prepare it.
- Dissassemble the LaCie unit (and you will have to void the warranty if you do this).
- Remove both hard drives from the unit.
- Connect both hard drives to your computer (internal SATA connections) and boot up your linux-distribution (for ubuntu, you can use the try without installing feature).
- Open a terminal and type sudo fdisk -l
- In this output, you should find the path for both hard drives, the first should be something like /dev/sdb2 487379970 (blocks), the second drive does not have a partition and should show up like /dev/sda (or sdc depending on your existing hardwareconfiguration):
ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x65764f20 Disk /dev/sda doesn't contain a valid partition table Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 125 1004031 5 Extended /dev/sdb2 126 60801 487379970 83 Linux /dev/sdb5 1 16 128457 82 Linux swap / Solaris /dev/sdb6 17 17 8001 83 Linux /dev/sdb7 18 18 8001 83 Linux /dev/sdb8 19 34 128488+ 83 Linux /dev/sdb9 35 125 730926 83 Linux
- With a text editor, open up /etc/mdadm.conf under the 130mb (128488+) mount, this is the LaCie raid configuration file.
- Make sure you have mdadm installed (sudo aptitude install mdadm for ubuntu).
- Open up command prompt/terminal and type sudo vi /etc/mdadm/mdadm.conf. This is the new RAID config file.
- Copy the settings from the Lacie config file in step 7 to the new config file in step 9. Change the paths to match your current setup. The smaller mount goes first and the bigger one (without the partition) second. should look like:
DEVICE /dev/sdb2 /dev/sda ARRAY /dev/md0 level=linear num-devices=2 UUID=163218f3:299b9ccc:3c666c38:60539313
- Now in terminal type sudo mdadm --assemble /dev/md0
- Mount the new disk where you want, f.ex. sudo mount /dev/md0 /mnt
- You're done, the data should now be available.
