    Re: Error while mounting ntfs drive.

    After deleting the old mountpoint and specifying a new one, and reinstalling ntfs-3g it now works again. Weird.

    Maybe the old mountpoint was instead conflicting with hdXY, or maybe it was ntfs-3g? Haha, anyways I'm glad it works now.

    Thanks for the help.

    Re: Error while mounting ntfs drive.

    Too soon to cheer ...

    After 3 reboots it is now happening again, error: error while mounting /media/mediadrive.
    This is the new mountpoint I made...

    Re: Error while mounting ntfs drive.

    Gparted will often have a yelllow or red icon on a partition with issues. Clicking (right click?) on icon may tell why it has issues. Often with NTFS it just suggests chkdsk.

    From Disk Utility or Disks click on drive and on right side is Smart Data info on drive. Is it showing any issues. New drive should not but even new drives sometimes have issues.

    Re: Error while mounting ntfs drive.

    Gparted is showing a green icon. Smart-Data says "drive is healthy". And chkdsk yesterday reported no errors too.
    I don't think the drive or the filesystem is faulty. I think the problem lies purely in the booting process. When I mount the drive in a gnome terminal, there are no problems at all - it uses the specified fstab mountpoint and works correctly.

    Could it be that the drive gets accessed by something before fstab can mount it?
    from the boot.log:

    Code:
    Mount is denied because the NTFS volume is already exclusively opened.  The volume may be already mounted, or another software may use it which  could be identified for example by the help of the 'fuser' command.  
    mountall: mount /media/hdd1 [897] terminated with status 16  
    mountall: Filesystem could not be mounted: /media/hdd1
    I pressed M at the errorscreen (manual recovery) and ran "fuser -vm /dev/sdb1" and "mount" and recorded the output:

    Code:
    root@Media-PC:~# fuser -vm /dev/sdb1
                         USER        PID ACCESS COMMAND

    Re: Error while mounting ntfs drive.

    Your error message is from your old mount, where is that from?

    I thought this was not now used:
    mountall: Filesystem could not be mounted: /media/hdd1

    What is mounted:

    /dev/sdb1 on /media/mediahdd type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,b lksize=4096)

    Re: Error while mounting ntfs drive.

    Yes, this was the old mountpoint. Sorry I copied the error message from my opening post.

    The fuser and mount output are recent. It seems that the HDD is already mounted at that point (during manual recovery - which is before gnome)?

    Re: Error while mounting ntfs drive.

    Were you not mounting hdd1 with fstab but with something else like a script or udisks?
    Or is entry in fstab still there for the hdd1?

    It seems like you are still trying to mount the same drive twice which is not allowed.

    Re: Error while mounting ntfs drive.

    Yes, that's exactly what I'm saying. Something accesses the drive before fstab does. At least that's what I'm thinking right now.

    I didn't manually make a script to do this, maybe it is a program I installed that I forgot about. I removed all entries from fstab now.

    Re: Error while mounting ntfs drive.

    When I remove the line from fstab completely, it still gets mounted during boot. It is then mounted with the label's name under /media/mediahdd. The label is mediahdd. When mounted this way I do not have write access.

    So something other than fstab mounts the drive during boot. Even _before_ fstab, because fstab reports the error "Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the 'fuser' command."

    WHAT MOUNTS MY PROGRAM BEFORE FSTAB DOES?
