Please tell me I didn't really screw something up

[watson524]

Hi all,

I got a new 1.5tb internal drive for Christmas. Machine currently running 8.04LTS. Has an 80gb internal drive where system files go. 2tb ext USB drive and a 250gb internal drive. Those are for media/data files

I put in the new 1.5tb internal (more on my issues with that in a later post) on the SATA3 controller and it put the 2tb on /dev/sdd instead of where it was at /dev/sdc. So I then unmounted the 2tb drive (mountpoint was /media/2tbext) and now it won't let me mount it again. I have a LOT of data on here that I need and I can't get to it.

I'm very new at this so it might be a simple question but basically, in gparted, it looks like it's mounted after a reboot (when I right click, the option is there to unmount) but when I look at it in places, it says I'm not privileged to mount the volume /media/2tbext. I went to a terminal and typed sudo mount /media/2tbext and it says failed to access mountpoint /media/2tbext: no such file or directory.

What can I do?

thanks in advance!

Nice Christmas present. :)

Very likely, your problem is to do with mount points and permissions. A good tutorial is here: http://www.psychocats.net/ubuntu/mountlinux

Yep, I'm sure that's the issue I just don't know how to fix it. I had read through that page you sent but I'm still stumped.

I can see the drive in fdisk

michele@michele-linux:/media/250gbint$

===========================

/dev/sdd1 is the current offender. And in gparted it looks "normal" to me but then after that in the tutorial, I get fuzzy. If I do the mkdir, I was afraid things would get overwritten or I wouldn't be able to see what's already there and so I'm stuck.

My fstab file looks like

============
michele@michele-linux:/media/250gbint$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# -- This file has been automaticly generated by ntfs-config --
#
# <file system> <mount point> <type> <options> <dump> <pass>

/dev/sdd1 /media/2tbext ntfs-3g defaults,locale=en_US.UTF-8 0 0

=========================
Before this started, the last line read /dev/sdc1 but since I plugged in the other drive and this drive changed to sdd1 I changed the fstab file too thinking that would help.

Can you post the contents of your /etc/fstab file?

Sorry, didn't see, you already have :(

[Irihapeti]

Try again..

OK, it's a NTFS partition. Then the link should be: http://www.psychocats.net/ubuntu/mountwindows

I'm following the steps but right away it says I'm not privileged to unmount (when I right click on it through the file browser side bar)

[watson524]

And I already have NTFS config installed but all that does is let me check off enable write support for internal and external devices.

[Irihapeti]

It sounds like you'll need to use sudo to unmount it. Have a look in the /media directory and see what directory it's using, and then enter

sudo umount /media/(whatever directory it is)

Note that it's umount with only one "n". (Just to confuse people)

Once your disk is unmounted, you can make directories with no worry about upsetting any of the contents.

[watson524]

When I am in terminal and type:


sudo umount /media/2tbext

It says umount: /media/2tbext: not found

[Irihapeti]

OK, then try "sudo umount /dev/sdd1"

If you wish, you could try "sudo umount -a" That tries to unmount everything that isn't in use by the system, so it will unmount the other drive as well.

If you wish, you could try "sudo umount -a" That tries to unmount everything that isn't in use by the system, so it will unmount the other drive as well.

sudo umount /dev/sdd1 gives "umount: /dev/sdd1: not mounted"
sudo umount -a gives:
umount: /media/250gbint: device is busy
umount: /dev/shm: device is busy
umount: /dev: device is busy
umount: /var/run: device is busy
umount: /: device is busy


I'm wondering if since this is an NTFS drive, is it easier to just plug it in to my ******* machine, copy off everything, then put it back in the Linux box and format it and start from scratch?

[Irihapeti]

You might be right about putting the drive in your Windows box and copying the files, especially if there's no real need to have NTFS in that particular computer. I'm probably a little out of my depth here, as it's a couple of years since I did anything with NTFS partitions.

If you still have problems after you've done that, then post back here and we can take it from there.

[watson524]

I'd like to stay NTFS since that's what my other drive in the Linux box is (and it's happy about it) so I'll move the data off the external and then how should I do it?

Plug it in to the Linux box and use gparted to format/partition etc? Then create the mount point and edit the fstab file so it's permanent and then put the data back on it?

It's about .5tb of data so it's going to take a while to move it.

I appreciate all your help!

[Irihapeti]

You need to make sure that the directories in /media already exist before you try to mount the drives.

While they are unmounted (or mounted to some other mount point) use the mkdir command to create the directories that are mentioned in your /etc/fstab listings. If they are refusing to unmount, it may be a good idea to reboot and then try the "sudo umount -a" command.

If the system is getting confused about which drive is which, you can use UUID numbers instead. To find out what those are, use the command

sudo blkid
while the drives are still installed.

Here's the output from my computer:

/dev/sda1: UUID="126bab5c-4f4c-473f-983a-6095e9bbe5cc" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda2: UUID="18eb5af4-930e-4bdc-b8d1-dc12696f31c6" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda5: UUID="cc3d2bf8-f19d-4a5c-981f-7bd601158434" TYPE="ext3"
/dev/sda6: UUID="1b1c7c3d-facb-41ad-85aa-b2b890382184" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda7: TYPE="swap" UUID="b2dccc3e-a50f-4e1d-9c7a-d7ada2f15922"


Then, instead of "/dev/sdd1" in your fstab file, you'd have UUID=(string)

[watson524]

Ok I got it sorted. After I moved all the data off and back to a ******* machine, I put the external drive on the Linux box and booted with the gParted live CD and was able to format the 2tb with no issues. Then I rebooted as normal, created the directory, mounted and shared and I can see everything as I expected (even from my ******* machines) so now I'm happily moving the data back.

thanks for all the input!

[Irihapeti]

You're welcome. Pleased to hear that it worked.
