Thanks for the article, it saved my life ;-)

For Knoppix user, booting from the live CD, use modprobe md before the mdadm command to load the md module into the kernel.

@ 'IGadget': that picture has been on the internets for a while and I couldn't find the original for it. If anybody does, please let me know so I can give proper credit.
Just search for water+cooler+raid in google...

@RobNY: if you just follow the instructions in the article you should have no problem recovering your data (as long as it's not a physical failure of the drive or the data is irremediably corrupted of course).

Just do something like:

mdadm --assemble /dev/md10 /dev/sdb4 --run

Then, if it worked, assuming you have a /mnt folder:

mount /dev/md10 /mnt

Now your data should be accessible from /mnt.

Hi how are you doing?
I manage to find this article about you trying to connect your MyBook 1GB! You mau be able to help me.

The 500 GB WD mybook stopped working, so after removing it from the enclosure and using a USB adaptor, Ubuntu won't automount it.
all of my files are in /dev/sdb4

Here's what I see using fdisk -l

Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00007c00 Device Boot Start End Blocks Id System /dev/sdb1 4 369 2939895 fd Linux raid autodetect /dev/sdb2 370 382 104422+ fd Linux raid autodetect /dev/sdb3 383 505 987997+ fd Linux raid autodetect /dev/sdb4 506 60801 484327620 fd Linux raid autodetect
