    Sounds like fun, actually, and I have done this before. Watch the
console messages for errors. Shouldn't need additional msgs, 'cept for the
ignore-errors flag.

    Also, if the disks are different geometries, there might be some issues
with partitioning and stuff. You'll wanna fsck the new disk twice before you
start using it to be sure.
