Hi Dan,
Thank you for your reply.
/proc/mdstat -> no such file or dir
/dev/md0 -> no such file or dir
mdadm -Q /dev/sdb2: -> device 0 in 2 undetected raid1
mdadm -Q /dev/sdb4 -> device 0 in 2 undetected raid1
mdadm -A /dev/md0 /dev/sdb2 /dev/sdb4
=>
mdadm: error opening /dev/md0
How do I create /dev/md0?
Thanks for your help and patience.
Yours Sincerely Stephen Grant Brown

Hi All,
I have a drive out of a Western Digital Mybookworld World edition drive.
cfdisk -Ps /dev/sdb
tells me that there are four partitions and this drive and that the file
system is "Linux raid" on all four partitions.
How do I mount this partitions so that I can copy the files on this
partition onto another drive?
You may or may not be able to do so.
Install mdadm (apt-get or aptitude) if you don't have it
already.
Plug in the drive.
Check /proc/mdstat to see if anything is being mounted. If so,
you have a /dev/mdX filesystem available to you now.
If not, you want to investigate the partitions:
mdadm -Q /dev/sdb1
(and the same for the other partitions)
Do you have all the partitions that were part of a RAID set? If
so, you can assemble them:
mdadm -A /dev/md0 /dev/sdb1 /dev/sdb2...
or something similar.
If you don't have needed partitions, you may not be able to get
anything. You may be able to reassemble a partial set of a RAID1
or RAID5 set.
