    I solved my own problem a while back and neglected to post my solution.
    I hate it when people do that to me. :)

    My original post is here:

    http://lists.freebsd.org/pipermail/freebsd-questions/2004-November/064038.html

    The summary is simply this: when rebuilding a mirror on a 3ware 7000-2,
    the rebuild would crap out with a vague disk error message. Doing a dump
    on the volume uncovered a couple of read errors.

    Solution:

    The read errors were killing the rebuild process. The hard disk's
    built-in SMART error correction was not kicking in though, because it
    only corrects bad sectors on a write. I tried to fix the disk with fsck,
    but the damage was too low-level, I guess...

    Anyway, I deleted the files with read errors--luckily they were
    trivial--and then copied a load of files to the partition to fill up the
    empty space. This triggered a SMART sector repair--I verified that with
    a SMART checker from ports.

    Once the bad sectors were remapped, I was able to rebuild my array.

    Hope this helps someone!
