Mount External Hard-Disk in read only mode

[DieUbunt]

Hi,

I have Ubuntu Jaunty and I need to mount external hard-disk in reading mode only.
Could you suggest me a pratical method to do that automatically.
Is It possible to setup any option that it does that?
Thanks in advance;)

if you want to do it in the fstab just give it the ro option

In fstab I don't find any information about new hard-disk.
I have found only in mtab

Thanks

This is information that I have found in /etc/mtab :

/dev/sdb1 /media/disk fuseblk rw,nosuid,nodev,allow_other,blksize=4096 0 0

Try below command

sudo mount -t ntfs-3g -o umask=222 /dev/sdb1 /media/mountpoint

you will have to put the entry into fstab, it is simple/dev/sdb1 /media/disk ext3 ro 0 0

replace the ext3 with the filesytem used on the disk

can you post your fstab

[DieUbunt]

can you post your fstab

have you made the mount point /media/PACKARDBELL ?
sudo mkdir /media/PACKARDBELL

[DieUbunt]

have you made the mount point /media/PACKARDBELL ?
sudo mkdir /media/PACKARDBELL
Yes but now I have the msg :

Impossible mounting volume PACKARDBELL

Yes but now I have the msg :

Impossible mounting volume PACKARDBELL


where are you seeing said message? and are you sure the filesystem is vfat? what did you format the drive with?

its pendrive usb.
I took this information ( vfat ) from mtab.
I have the message by pop-up window:

only root can mount dev/sdb1 on /media/PACKARDBELL

Now gave me also this msg :

Impossible mounting <PACKARDBELL>
DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

[Boondoklife]

this is normal as mounting is a superuser thing, you can try to get around this by adding user as an option in fstab. but do keep in mind if that is the case then there is nothing stoping the user from unmounting it.

So what must I do to modify fstab in that way?
How could I umount later that volume?
thanks

:D Perfect
I have resulted inserting in fstab the row :

/dev/sdb1 /media/PACKARDBELL vfat user,ro,umask=0222 0 0

Good
It's that I wanted
Thanks a lot

this is because it is not there to begin with and when you plug it in dbus tries to mount it and the drive name is already taken.

ok let's go about this another way that may be more user friendly to you, get rid of that line in the fstab. then put the drive in and wait for it to mount and show up on the desktop. from there right click on it and goto the drive tab and click on settings. from there add ro as an option and see what you get.

Now It works fine and I know a little more about fstab and mtab functionality

Bye bye:D
