I'd highly recommend using rsync for copying the files. In my years
with Myth, I've tried all sorts of things (from mv to cp to dd (on
individual files)--note you can /not/ use tar or cpio or zip--even in
passthrough mode--because they all have 2GiB file size limitations) and
rsync had a /lot/ of advantages. You can use something as simple as
rsync --av --progress /mnt/video/* /new/drive/directory
(read the man page to make sure you do the trailing slashes properly).
And note that you can also specify --bwlimit to limit I/O bandwidth
(i.e. be even nicer than ionice can be) if you're continuing to use
other stuff on the system during the copy.
