Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I have an OS X Lion recovery stick that I would like to access, specifically to use it to install Lion in a Virtualbox VM. I notice that Windows detects and mounts the recovery stick as an optical drive. I know the drive works, because I am able to install Lion from it on a Mac. In Ubuntu, the drive does not automount, and I cannot figure out how to mount it manually. Ubuntu version is 11.04 amd64. I have not found any forum posts or comments from other people trying to do this.

  • The output of wodim --devices:

    0 dev='/dev/sg3' rwrw-- : 'APPLE' 'USB DISK'

  • When I try to mount it with sudo mount -t iso9660 /dev/sg3 /mnt:

    mount: special device /dev/sg3 does not exist

  • When I dmesg | tail:

    [12825.417616] usb 2-1: USB disconnect, device number 60
    [12826.140121] usb 2-1: new high speed USB device number 61 using ehci_hcd

    [12827.728188] sr 44:0:0:0: Attached scsi generic sg3 type 5

Any ideas how to mount this volume and read from it?

insert your disk then check in disk utility –  shantanu Mar 22 '12 at 21:19
Thanks for the tip. In disk utility, the drive is detected, but it is detected as empty. I also notice that the detected partitioning is Apple Partition Map. This made me think to try the hmount program included with hfsutils. However, that outputs hmount: /dev/sr0: not a Macintosh HFS volume (Invalid argument) –  Erik Mar 22 '12 at 22:01
