That will wipe the whole da1 disk , not just a partition on it.
I don't know what you really need, but something
would make the current stuff on the e partition of slice 1 on disk da1
unreadable short of using one of those heroic super recovery services.
If you want the old stuff back, sandwich that with the
backup and restore.
