    USB HD Mounting issues


    I currently installed a USB External Disk drive on my gentoo machine running
    2006.1 AMD64 release.

    When I plug in the USB disk I can mount it fine. The problem I'm having is when I reboot the machine.

    dmesg show the drive and assigns it /dev/sde1. When I try to mount it,
    the system say's "allready mounted".

    If I type mount, nothing is showing up for this device. Also, I never listed it in fstab / mtab to mount.

    Please advise.

    Thanks

    For the (device already mounted) do you have HAL service that it's mounting the hard drive automatically ? usually the device will be mounted in /media !

    boot the machine and plug in the Drive once your machine is done booting,type.

    tail -s 3 -f /var/log/message (post here ), and try to mount it.

    Regards.

    Usb Mounting Problem on reboot

    Aliov,

    I donít have HAL service installed on the system.

    Hereís the kernel / gentoo revision Iím currently running.

    #uname -a

    Linux qdmi64 2.6.15-gentoo-r7 #1 SMP Wed Jul 11 14:56:42 EDT 2007 x86_64 Dual Core AMD Opteron(tm) Processor 270 AuthenticAMD GNU/Linux


    Hereís the output of dmesg, donít have a file called /var/log/message, when I reboot the machine and then plug in the USB Disk Drive.
