How to Mount or Unmount a USB Mass Storage Device With vold Running

  1. Display device aliases for all removable mass storage devices, including USB mass storage devices.

    $ eject -n
    rmdisk0 -> /vol/dev/rdsk/c4t0d0/clik40    (Generic USB storage)
    cdrom0 -> /vol/dev/rdsk/c0t6d0/audio_cd   (Generic CD device)
    zip1 -> /vol/dev/rdsk/c2t0d0/fat32        (USB Zip device)
    zip0 -> /vol/dev/rdsk/c1t0d0/zip100       (USB Zip device)
    jaz0 -> /vol/dev/rdsk/c3t0d0/jaz1gb       (USB Jaz device)
  2. Mount a USB mass storage device by using the device aliases listed previously.

    $ volrmmount -i device-alias

    This example mounts a USB Jaz drive under /rmdisk/jaz0.

    $ volrmmount -i jaz0 

  3. Unmount a USB mass storage device.

    $ volrmmount -e device-alias

    This example unmounts a USB Zip drive from /rmdisk/zip0.

    $ volrmmount -e zip0
  4. Eject a USB device from a generic USB drive.

    $ eject device-alias

    For example:

    $ eject rmdisk0

    Note –

    The eject command also unmounts the device if it is not unmounted already. The command also terminates any active applications that access the device.
