    O.K. After formatting it -- did you label it? (Usually after
    partitioning if it is a second drive -- but the partitioning will be
    otherwise set to a default based on the size of the drive -- and
    probably changed by the install process.

    But format is only a low-level format. You need to do the label
    (another option from within the format program). Once it is labeled,
    the OS should recognize it.

    "Unformatted" probably means "not labeled" in this case.

    Note that if it is a FC drive which has been used in a hardware
    RAID array, you will have difficulty formatting it at first. There is
    only one sequence which I know to work (from a booted system) This is
    from memory, so I might have something wrong.

    1) Plug in the drive.

    2) issue the command "devfsadm -c disk -C" to make the necessary
    device entries (including symlinks from /dev/c1t2d0s* to the
    actual special device files) -- assuming that this is a second
    drive in the machine)

    3) "format -e c1t2d0" (Assuming that you are formatting the
    second drive in a SB-1000 or SB-2000. Note that you don't need
    to type the slice (e.g. "s2") for the format command.

    4) as the *first* command from within format -- let it auto-detect
    the drive type. (If you do *anything* else in format, such as
    trying to partition it, you'll have to start over.)

    5) It will then print a message saying that it needs to reformat
    to change the sector size to 512 bytes. Accept this, and sit
    back for a while (an hour or more depending on the size of the
    drive).

    6) Once this is done, partition and label the drive. Because
    of the "-e" option, you will get two choices of label formats,
    and you should pick the first of the two, even if it is
    currently the second one -- which is an other RAID format.)

    Note that if you formatted the drive before with no troubles,
    this does not apply to this drive -- but it *did* to a collection of 20
    72GB FC-AL drives which I got from a hamfest for $10.00 each. Once this
    is done, the drive is fine and ready for use.

    O.K. Were you able to boot from that? If using the built-in
    USB port (USB 1.2, I think) it would have been very slow.

    Good.

    Mostly, check whether the drive has been labeled after
    formatting.

    Good Luck,
    DoN.
