Kubuntu 10.04, i386, new install. Can't access EXT4 partition on same HDD. Celeron, desktop.

Thank you.

I rarely use the console. So, I am still very dumb when using it!

Kubuntu 10.4 should out of the box support ext4. If you want to list the partitions on your computer use if you want to list the mounted partitions you may useor if you want to mount a partition you'll have to use the mount command. As an example, if you have a partition /dev/sda7 which is not yet mounted and have a directory /mnt/tmp you may use the commandwhich mounts the partition to the directory.

What's on the ext4 partition? Data? Another operating system? How have you tried to access it? Do you have a mount point for it? Is it mounted? I don't have Kubuntu so I don't know where you access the terminal, probably the Menu icon?? get your partition information using this command as root (sudo): sudo fdisk -l (lower case letter L in the command). Also, take a look at the /etc/fstab file to see what you have. If you don't understand it, post it here.

Thank you.

Before I follow your instructions, I want to know if there is a way to have my partitions automatically mount upon every boot, without a prompt for password.

surely, if you configure it in the /etc/fstab file.

Markus

ok more on the auto in a moment. fdisk coming next:

I am trying to be able to read/write files in sda4

neally@honeybear:~$ sudo mount /dev/sda4 /mnt/tmp
mount: mount point /mnt/tmp does not exist

Well, this tells you, that /dev/sda2 is not yet mounted.
And since /dev/sda4 is mounted to /media/disk, there is no problem for your Kubuntu to access the filesystem.

Markus

Edit: as I wrote "if you have a directory /mnt/tmp" if not, create one. But you don't need it since the partition is already mounted.

I suppose it says sda4 is mounted?
But in Kubuntu's GUI file manager, Dolphin, It won't let me so much as write new folder. I can not see any files on it.

Ok? All I know is I can't use sda4. Dolphin won't let me.

I don't remember these problems on my last computer, with Kubuntu 9.10.
How can I use my filesystem?

Well, you can write to it only as root. And if you open dolphin as a normal user, you don't have root-permissions.

There are two ways: write to the partition as root on the commandline, or create folders as root and change the owner of the folders to the normal user which then will have write-permissions within the folders
