    Default Can't mount second hard drive

    Hi,

    I am a recent (very recent, about 1 hour ago..) convertee from Ubuntu.

    This is my first foray from ubuntu (other than Mint) so i am a little bit lost.

    I am trying to mount a hard drive that only a few hours ago was fine in Ubuntu.

    Can anyone help?

    Here is the output from fdisk -l :

    Code:
    Disk /dev/sda: 80.0 GB, 80000000000 bytes
    255 heads, 63 sectors/track, 9726 cylinders

    Disk identifier: 0x41ab2316
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1               1        3187    25599546    7  HPFS/NTFS

    the drive in question is sdb1. It is formated in ext3 and contains data i need to access.

    I am pretty sure this is going to be something dumb that i'm missing but any help is appreciated.

    Can you also post the output of

    mount
    If using KDE 4, your external drive will not mount, until you click on the appropriate drive icon within Dolphin (file manager) for example. It should show up after this.

    Code:
    /dev/sda5 on / type ext4 (rw,acl,user_xattr)
    proc on /proc type proc (rw)
    sysfs on /sys type sysfs (rw)
    debugfs on /sys/kernel/debug type debugfs (rw)
    udev on /dev type tmpfs (rw)
    devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
    /dev/sda6 on /home type ext4 (rw,acl,user_xattr)
    /dev/sda1 on /windows/C type fuseblk (rw,noexec,nosuid,nodev,allow_other,default_permissions,blksize=4096)
    rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
    thanks for the speedy reply.

    It is an internal HD, not external and i cannot find a drive icon to click on.

    For internal drives, you may need to adjust /etc/fstab permissions. The easiest (graphical) way to do this, is to use YaST > System > Partitioner utility. Navigate to the volume concerned, and edit the fstab options so that the you have access to it as user.

    A useful reference for you:

    Edit: Ignore the ntfs info, just the permissions info.

    cheers,

    in partitioner whenever i try to edit anything to do with the /dev/sdb i get a message saying it is in use.

    I try :

    Code:
    umount /dev/sdb
    i get a message :
    Code:
    Could not find /dev/sdb in mtab
    umount: /dev/sdb is not mounted (according to mtab)
    i have also tried the above using sdb1

    It will probably be mounted by root. From a console:

    mount (to see what is actually mounted and where)

    You should be able to unmount it with

    su (to become root, enter root password when prompted)
    umount /dev/sdb1 (or whatever the appropriate device is)
