Metadata has different format and stored on a pre-assigned location of
hard devices. DDF1 and ISW store their metadata on different locations.
That means both of them can work together. (It's messy somehow.) It
requires a tool to create a kind of metadata and write it to the
corresponding hard devices. Intel OROM has the ability to do that and
I'm sure different venders provide its own way to facilitate it too.
(That won't happen automatically and requires user involvement.)
Therefore, an Intel board doesn't mean the hard disks have the ISW
format. The output from "dmraid -s -ccc" tells me that the reporter has
the DDF1 format on his/her disks. The DDF1 metadata won't go away until
"dmraid -rE " is conducted. 

Also the below dump shows that the name of the t-group raid set is
".ddf1_disks". If you use that name as the command line argument,
"dmraid -s -ccc .ddfa_disks" should work. I'm working on ISW metadata
creation now and will tackle this issue later as ISW format experiences
the same. 

As far as the crash, I have no idea where the bug is and will keep an
eye on it. 

BTW, I wasn't aware the issue until last email I got for the mailing
list. Could you point me to the original one?

Thanks,
Ying
