Until yesterday my Ubuntu 10.10 was booting perfectly. Today I was greeted with the message:
"An error occurred while mounting /media/drive
Press S skip mounting or M for manual recovery.

I press S and it then boots normally.

Anyone know the fix for this?

Do you have an external drive uplugged?

Hi there

I don't have an external drive just a USB although simultaneously I did have a problem with a second internal hard drive.

It was functioning fine and then today it appeared to have unformatted itself.
I've since re formatted and it is now functioning normally.
The only other thing I did prior to the problem was to download 'Storage Device Manager'.
Whether any of the above ids related I can't say!

Run boot info script and post results. (http://sourceforge.net/projects/bootinfoscript/)

Hi there,

Excuse my novice ignorance but how to I obtain the 'Boot Info Script"?

Re not knowing about spaces: neither do I!

Thanks...all

Thanks...allHi, click on the script link that jtarin posted, I know took me awhile to realize the words he types are links a lot of time like in this case, I thinks it is because he is such a jokester. He make me laugh at the things he posts.

Actually I have always done it this way. I don't like links in plain site......goes back to the days of link spamming.

I wouldn't recommend spaces. You should use UUID.

Converting to UUID. (https://help.ubuntu.com/community/UsingUUID)

Hi there'
I think this is what you requested.
Took me some time to figure out how it works.
Too used to windows and click on 'setup' methodology.
Someone suggested delving into the UUID . What!
Is Ubuntu supposed to give one a headache!!:lolflag:

Your fstab file is messed up.

1. You cannot have the mount point as "/media/Drive Two". The space between Drive and Two is throwing it off
2. You're trying to mount /dev/sdc1 three times. 2 times to the same location with different mount options, and 1 time to /media/sda2

To fix number 1, I would recommend changing the mount point to a folder without a space in the name. If you really want that space then try using the following:


/dev/sdc1 /media/Drive\ Two vfat defaults 0 0

To fix number 2, simply get rid of all but two of the mount lines for /dev/sdc1

+1 on compmodder26 suggestions.

After using Linux for a while, I stopped using spaces. Even my shared folders with windows do not have to have spaces.

I do use others ways to highlight like CamelCase, Under_score, with-dash, or justonename.

mkdir drive_two
or
mkdir DriveTwo

Edit fstab:
gksudo gedit /etc/fstab

/dev/sdc1 /media/drive_two vfat defaults 0 0

Better to use UUID:
UUID=19F2-323B /media/drive_two vfat defaults 0 0

After all edits run this to make sure there are no errors. If is just returns then it is ok.

sudo mount -a
