Hi all,
My apologies in advance if I'm in the wrong place, but my attempts to
find a solution lead me here time and time again. :)
I'm having some trouble using a simple two-disk RAID-0 array with an
Adaptec 1210SA card. My exact problem has been well described almost two
years ago, here:
https://www.redhat.com/archives/ataraid-list/2007-February/msg00007.html
Unfortunately no-one has ever replied with any solution that I can see!
Here's some useful output to supplement my shameful thread revival:

And I'm not sure if this will be useful, but here it is anyway:

Of course, the simplest answer would be to try 1.0.0-rc15 and see how it
goes. I've downloaded the source and checked the changelog: tere's no
mention of a fix pertaining to this issue, and as I also rely on dmraid
for my boot devices I'd rather not break it without a tested package
with which to install (unless I had no other choice, you understand.)
I could also update to Ubuntu 8.10, which is planned, but I've noticed
that the version included in this release is still only at 1.0.0-rc14.
What has happened to rc15 in Intrepid? Is there a package update planned
by the maintainer?
I'm more interested in finding a solution to the problem, and learning
more about the checksums. Is there some way I can begin investigating
this issue myself? Unfortunately, I fear my aspirations shall run away
with me, but any insight/starting information to fixing the problem
would be welcome.
Thanks for reading! Any ideas are more than welcome.
Regards,
Tom
