DNS-323 RAID-1 Volume missing, Linear Volume availible.

Noob question.
Before I'm flamed for not reading the sticky on known issues. I did read it and it didn't really cover my issue.

My current setup.  Firmware 1.00
I have one Raid-1 volume and 1 linear volume.
Noticed that my Raid-1 volume is not available as a share, while my linear volume is.
rebooted the DNS-323 a couple of times with the volume still not showing.
Any helpful hints would be appreaciated

Edit :Is there any other way to submit a SMB restart, without using Telnet?

More information about the current config.
Missing volume is HDD_1 Raid 1 
availible volume is HDD_2 linear = (JBOD)
2 300 gig maxtor drives
Partitioned 200 gigs  Raid 1  the rest is linear

Went ahead and picked up a 3rd party piece of software that found my data with no problem.
I didn't want to install fun plug because I was afraid it would corrupt the missing partition further.

Good to here you got your data back - what was the software you bought, and what steps did you have to take?

I used Quick Recovery Linux www.unistal.com.  It's availible in two flavors. Linux  (naturally) and  Windows.

I plugged the drive in with my USB to SATA adaptor.  Once windows recognized the drive I ran the util and the data was recovered quickly.

I'm sure there are  freeware  utils  out there; that do the same thing, but I was in a near panic and I needed to get my data back.

I went ahead and updated the DNS-323 firmware to 1.04 and reformatted my formated my drives.  Then I copied everything back into the DNS.

One thing tried before I used this software. A more advanced Linux user may have more success than I did.

  Using Knoppix 5.1  reference (www.howtoforge.com/recover_data_from_ra … partitions)
entered root: sudo su

mdadm --examine --scan /dev/hda1 >> /etc/mdadm/mdadm.conf                             [hda1 could be something else mine was cda2]

added devices=/dev/hda1,missing       to the mdadm.conf      [I used vi here I fn' hate vi]

edit the file in /etc/default/mdadm

change
autostart=false to autostart=true


Start the raid
/etc/init.d/mdadm start
/etc/init.d/mdadm-raid start

ran
cat /proc/mdstat 
to see if the raid was working and it was.

Here's where things went wrong and is why I went ahead and purchased software.  If a more advanced Linux user could show me where I went
wrong I would be most appreciated.  The 3rd party software money well spent for recovering data, but that doesn't mean everyone
else has to.

I tried to extract the volume information using the following command

dd if=/dev/md0 bs=512 count=255  skip=1 of=/tmp/md0.txt

after creating the file I opened it in vi and as expected there was a bunch of binary gibberish,  but there wasn't any volume information.

After a couple days of searching and expanding the amount of information to be extracted I gave up.

I should have been able to see something like this in the md0.txt

"volGroup00 {
                  id = "xxxxxx-xxxx-xxxx-xxxx-xxxx-xxxx-x
seqno =2
status =["RESIZEABLE", "READ", "WRITE"
....etc.

I didn't see that and I couldn't figure out how to.  If anyone one has any luck using this I'd like to see what they did.
