Solaris 8 System Administration Supplement

How to Format Removable Media for a UFS or UDFS File System

  1. Format the media.

    $ rmformat -F quick device-name
  2. (Optional) Create an alternate Solaris partition table.

    $ rmformat -s slice-file device-name

    A sample slice file looks like the following:

    slices: 0 = 0, 30MB, "wm", "home" : 
                  1 = 30MB, 51MB : 
                  2 = 0, 94MB, "wm", "backup" : 
                  6 = 81MB, 13MB

    See System Administration Guide, Volume I for information on creating an alternate Solaris partition table.

  3. Become superuser.

  4. Determine the appropriate file system type and select one of the following:

    1. Create a UFS file system.

      # newfs device-name
    2. Create a UDFS file system.

      # mkfs -F udfs device-name

Example--Formatting Removable Media for a UFS File System

The following example formats a diskette and creates a UFS file system.

$ rmformat -F quick /dev/rdiskette
Formatting will erase all the data on disk.
Do you want to continue? (y/n)y
$ su
# newfs /dev/rdiskette
newfs: construct a new file system /dev/rdiskette: (y/n)? y
/dev/rdiskette: 2880 sectors in 80 cylinders of 2 tracks, 18 sectors
        1.4MB in 5 cyl groups (16 c/g, 0.28MB/g, 128 i/g)
super-block backups (for fsck -F ufs -o b=#) at:
