    Did I kill my removable hard drive formatting it EXT4?


    So I have a 1TB MyBook removable hard drive that was working fine. I got the brilliant idea to reformat it using EXT4 instead of NTFS using Gparted. Now I can't get my Ubuntu 12.04 system to even recognize it when I plug it in. Wondering what I did wrong and if there is a way to fix it.

    Any help out there?

    The mount command plus fdisk -l plus cat /etc/fstab terminal readouts may shed some light in your thread with the

    Here you go. Warning... I have two internal hard drives and a pile of partitions. (major multi-boot distro hopper!)

    mount
    /dev/sda9 on / type ext4 (rw,errors=remount-ro)
    proc on /proc type proc (rw,noexec,nosuid,nodev)
    sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

    none on /sys/kernel/debug type debugfs (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)

    cat /etc/fstab
    # /etc/fstab: static file system information.

    I could not get any output from fdisk -l.

    You might need to either use /sbin/fdisk -l or sudo fdisk -l.

    Well - problem solved. I saw it wasn't even recognized in fdisk and tried unplugging and re-plugging the hard drive while still plugged into the USB. Now it has recognized it. Thanks for your help. If you see any improvements I should make in my fstab let me know. I still don't fully grasp what I am doing in there.

    Code:

    Fstab entry by UUID is best instead of /dev/sdb so don't touch it. I see nothing needing changes. Since problem solved. Marked thread solved with thread tools. Only the original poster can mark the thread as solved.
