How To Solve Disk Mount Error in Ubuntu

I have several partition on the hard disk of my laptop. Some of them are NTFS and some Ext4. I prefer to auto-mount all the partitions at startup. It saves me trouble and time. I prefer to auto-mount the partition by editing the fstab. This was the first time I was trying to automount an Ext4 partition by editing the fstab. But it gave me the following error when I tried to mount the partition:

mount: wrong fs type, bad option, bad superblock on /dev/sda7,
missing codepage or helper program, or other error
In some cases useful info is found in syslog – try
dmesg | tail or so

When I tried to mount the partition via GUI, it gave me the following error:

Unable to mount 80 GB Fliesystem
Error mounting: mount exited with exist code 1: helper failed with:
mount: only root can mount /dev/dsa7 on /media/80GB

Where /media/80GB is the location where I was trying to mount it.

dmesg | tail command showed me the following result:

[ 2123.530257] [] ? ieee80211_scan_rx+0x190/0x190 [mac80211]

Fixing disk mount error

The problematic part was pointed by dmesg. It had trouble with uid=1000. Actually I had edited the /etc/fstab file to include the following line to auto-mount the Ext4 partition:

UUID=f920adf0-6038-4145-8214-4e1b79ca2d9b /media/80GB ext4 defaults,uid=1000 0 0

I changed it with the line given below to remove the troublesome “uid=1000”:

UUID=f920adf0-6018-4145-8314-4e1b79ca2d6b /media/80GB ext4 defaults 0 0

The automount of the partition worked fine afterwards. Cheers :)

  • This is obviously a programming failure, system, application or other.
    Mistakes like these should be an upgrade fix not a user fix.

  • I get the same error while mounting a network drive. i.e. mount:only root can mount \1XX.XXX.XX.XXvolume1. could you help me out?
