BTW: is there a way to hint rasync not to recalculate the md5sums on each invocation but to cache them permanently? A manual cache in an external file would do
Then buy another hard drive and add it to the computer. If you are currently employed, this may be even a cheaper use of your time than fiddling with strange filesystems, repartitioning your hard disk, etc.
Another option, if the changes are confined to few files, is to use CD-R/W or DVD for saving the files, which truly don't change.
