Re: Trouble copying a large number of files to last ext2 partition

Andrew,

Thanks for your nice feedback. This is extremelly helpful.

Is it possible to change anything on the current partition without
reformatting it or am I just doomed to tarball all the content, move it
somewhere else (I can always zap my macos 9 partition I haven't touched for
months...) and then mkfs, then restore files? It would be nice if I can
change reserved space and goof with inode stuff without doing that though.

Thanks for your help,

Laurent
