I've gotten into a wierd situation where the best course seems
to be wipe a (BSD) partition - without chnaging the size or location
- and then restoring from backup.
Based on the Handbook (sec. 12.3.2) the correct would seem to
be:
make backup
cd /
dd if=/dev/zero of=/dev/da1 bs=1k count=1
newfs -O 2 -U /dev/da1e
restore from backup
Have I overlooked anything?
That will wipe the whole da1 disk , not just a partition on it.
I don't know what you really need, but something
like
cd /
umount /dev/da1s1e
newfs /dev/da1s1e
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.
