Assistance with mdadm.conf syntax for reassembly of existing RAID0

Hello everyone. I'm trying to recover a friends data from a Sony Vaio VGN-AW47GH Laptop. It has a pair of Toshiba MK5055GS 2.5" 500GB HDD combined (according to my reading) into a 1TB RAID0. The laptop is no longer working so I'm trying to bring them up on my Ubuntu 14.04 system.

I need help with the syntax for the /etc/mdadm/mdadm.conf file to make the RAID0 mountable by Ubuntu. Hopefully someone familiar with mdadm.conf is able to point me in the right direction as the man page and searches online aren't making it clear enough for me to tweak.

They are appearing as /dev/sda & /dev/sdb and I get the following from mdadm examine/scan after ruing "mdadm --assemble --scan"

Code:

# mdadm --examine --scan /dev/sda
mdadm: ARRAY line /dev/md/imsm0 has no identity information.
ARRAY metadata=imsm UUID=99fcd315:2ac78f08:08014b0a:33f4585f
ARRAY /dev/md/Volume0 container=99fcd315:2ac78f08:08014b0a:33f4585f member=0 UUID=245d2401:2ad11a3c:6edacb92:47ce3340

Code:

# mdadm --examine --scan /dev/sdb
mdadm: ARRAY line /dev/md/imsm0 has no identity information.
ARRAY metadata=imsm UUID=99fcd315:2ac78f08:08014b0a:33f4585f
ARRAY /dev/md/Volume0 container=99fcd315:2ac78f08:08014b0a:33f4585f member=0 UUID=245d2401:2ad11a3c:6edacb92:47ce3340

Here's the exammine results without the --scan option:

Code:

# mdadm --examine /dev/sda
mdadm: ARRAY line /dev/md/imsm0 has no identity information.

There doesn't appear to be a /dev/md/Volume0 file in dev. There are a few md files now though:

Code:

# ls -la /dev/md* | grep md
brw-rw---- 1 root disk 9, 126 May 24 22:05 /dev/md126
brw-rw---- 1 root disk 9, 127 May 25 22:27 /dev/md127
/dev/md:
lrwxrwxrwx  1 root root    8 May 25 22:27 imsm0 -> ../md127

Code:

# mdadm --examine --scan /dev/md126
mdadm: ARRAY line /dev/md/imsm0 has no identity information.

Code:

# mdadm --examine --scan /dev/md127
mdadm: ARRAY line /dev/md/imsm0 has no identity information.
ARRAY metadata=imsm UUID=99fcd315:2ac78f08:08014b0a:33f4585f

Any and all (constructive) input greatly appreciated!
