Can't mount/see external harddrive

Asked by austin b on 2012-02-01

Hi. I recently upgrade from an old version of Bodhi linux to Ubuntu 11.10. Using the live usb i could use my firewire external harddrive. Since a proper installation it won't appear....

mount && sudo fdisk -l shows:

/dev/sda1 on / type ext4 (rw,errors=remount-ro,commit=0)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfs-fuse-daemon on /home/austin/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=austin)

any ideas?

Hi,

Lets say you have pen drive connected to your machine and after upgrade your aren't able to see the same in the output of mount command.

1. Use sudo fdisk -l to get list of the devices connected to your machine.
2. Try mounting the device to some mount point i.e ( mount <device name> <mount point> )
3. Now you would see the device when you run mount command.
4. If not by the above mentioned method then in GUI try accessing the device once and then it would be visible in mount command output.

For. eg.

1. Pen drive connected to the machine but not visible to mount command.

raj@raj-desktop:~$ sudo mount
/dev/sda7 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)

none on /dev type devtmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/dev/sda6 on /home type ext4 (rw)
/dev/sda8 on /mnt/fly type ext4 (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfs-fuse-daemon on /home/raj/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=raj)

2. But pen drive visible to sudo fdisk -l.

raj@raj-desktop:~$ sudo fdisk -l

3. Accessing the device through CLI or using GUI as you wish, but I am doing using GUI.
4. Now device visible in mount command output.
