I had one instance where I nedded to use dmraid -r -E /dev/sdX to clean
disk. As far as I remember, partitions were not deleted, it's just
metadata.
Quick online search for "dmraid -r -E" never mentions data loss neither,
so you should be fine.
BUT, if you can, backup would be preferable for any live work with
important data, and "sfdisk -d /dev/sdX > partition.txt" will save
partition info so if anything goes wrong you can reapply it.
