Repair disk updating boot support partitions dating roanoke va
If the partitioning scheme is not specified, then an appropriate one for the current machine is chosen. Times is the optional (defaults to 1) number of times to write random information. In either case, in order to be useful again, randomized wholedisks will need to be partitioned, or randomized partitions will need to be erased (newfs'd), e.g. If you desire a more sophisticated erase algorithm or if you need to erase only free space not in use for files, use the secure Erase verb.
Erase, using a secure method, either a whole-disk (including any and all partitions), or, only the free space (not in use for files) on a currently-mounted volume.
until interrupted with a signal (For example typing Control-C).

When ownership is enabled, the Owner and Group ID settings that exist on the disk are taken into account for determining access, and exact settings are written to the disk as FSOs are created.
Old disks are removed live, the RAID volume does not need to be unmounted.

If you need to erase all contents of a partition but not its hosting whole-disk, use the zero Disk or random Disk verbs.
Level : Only the "mirror" type increases fault-tolerance.
Adding a hot spare to a mirror will enable autorebuilding for that mirror. Adding a new member to a concatenated RAID set appends the member and expands the RAID volume.
Remove a member or spare from an existing RAID set.
