I have a LaCie 500 GB USB hard disk, which I used on NW6.5, formatted with NSS, and is about half full. I am migrating to OES2-Linux, and would like to avoid formatting this drive if at all possible, due to the time it would take to back it up via network. I read the documentation for OES2-Linux about using EVMS, but it only mentions using it by creating new partitions. Is it possible to "apply" EVMS to existing partitions and devices, without the need to reformat?

Thanks in advance,
