I have a client that a lost mobo and he had a RAID0 with 2x40GB drives (why?
I don't know).
Now the problem is I need to get the data off that array and onto his nice
new big, fast drive I put in. The new mobo is RAID ready but how do I get
it to read an existing RAID0 array? I tried booting from arrayed drives but
No maas!

Can I slave the array by changing the jumpers then will OS read it?

I have a file retrieving s/w that will try to read RAID volumes but man what
a time killer.

Any ideas?

Forget that approach. Most hardware-RAID "solutions" are incompatible
between each other. After all it would not do, if you could just change
your vendor, now would it?

The actual data storage one RAID solution is supposed to be
compatible to another one (same level of course). But the
desctriptor blocks are usually not compatible at all. Block-sizes
and stripe-sizes are also an issue.

For thet reason I stay off hardware RAID and use software RAID instead.
Then all you need is for the software to still run. (Not an issue
with Linux.) For hardware RAID to be really more reliable you need
to have a spare controller handy.

Best approach: Get another instance of the old "solution". Maybe
you can borrow one somewhere? Maybe your customer knows a place
where it is also in use? Or maybe the vendor of the original
"solution" has a newer model or controller card that is downward
compatible?

You could also try a data-recovery company. They might have a working
original controller in their hardware storage, since that is how
they recover data in many instances.

Thanks, I was afraid that is the case. RAID on hardware level just doesn't
make since to me! I bet my client will never do it again LOL. The original
vendor is not talking to him now so I am the go-between.

Yes, LOL. Or poor trusting devil. Essentially your customer
has been ripped-off, like many others are being ripped off
at the moment.

Some time ago had the choice of going with hardware RAID or
Software-RAID for some installations. I now have 10 Arrays in 4
computers woth a total of about 2TB net capacity (all redundant) using
software RAID (all on partition level) and have ho regrets at all. The
lack of interoperability between different RAID solutions was just one
big killer argument. The lack of flexibility (i.e. just whole disk
as option) was the other big killer.

At least low-cost hardware-RAID makes no sense at all, except to
force people to stay with a specific vendor.
