RAID 5 rebuild problem

I have a question about rebuilding a 3 disk RAID 5 system running
Intel Matrix Storage Manager on an Intel DG965OT board.

Yesterday I moved the entire system (motherboard, CPU and disks) to a
new box that has more room. I reconnected the SATA cables in the same
order I took them off. I did not make any hardware changes except
that I removed some jumpers from my Seagate 7200.10 drives to remove
the 1.5G/s limit.

When I did the POST, the Matrix Storage Manager came up as failed RAID
volume and only 2 of the 3 drives showed up. I had forgotten to plug
in the last drive.

I reconnected the final drive. Now all three drives show up green but
the RAID volume is still red "failed". I have an option to rebuild
the array, but I am afraid that I will erase my data on my existing 3
disks.

Does rebuild automatically erase everything?

Did I do something wrong by removing the jumpers - should I replace
them?

Any help would be greatly appreciated - I surfed the forum but did not
find an answer.

Kind regards,

Telecentricity
