TOPIC

    I want to have multiple UFS partitions on my hard drive, but I can't seem to do it. Is this possible?


DISCUSSION

    Now it is not supported or possible to create multiple UFS volumes on the same physical hard disk. However, it is possible to add multiple physical hard disks and format them in UFS.

    To format a disk UFS, you may use a third party utility like Hard Disk Tools (HDT), by FWB, or a utility like pdisk or disk.

    'Pdisk' and 'disk' are in Mac OS X Server.
    /sbin/disk
    /usr/sbin/pdisk

    Pdisk and disk are two separate utilities. Pdisk can only edit the partition map of the drive, and does not format or initialize. Disk is used to initialize or format the drive/partition. It can also partition the drive but only into two partitions. You specify the size of the first partition and the second one is the rest of the drive.

    The man page has further information on pdisk and disk. Pdisk is complex and the man pages should be consulted before using pdisk on any hard disk.

    Also, if the hard drive already has a format (HFS/HFS+, Dos), it should automatically mount, and customers can use the 'initialize...' option under theTools menu in WorkSpaceManager.

    Note: Any of these processes will erase the disk, removing all data.
