unaccessible and not used 1.2 Tb ghost ext4 partition made during installation

English Install/Boot/Login
1

First of all, I am not sure this is the right forum, its more about partitions, but it is a bit like it.

This is the problem;
I have a problem concerning my partitions;
I run Opensuse 11.3 KDE 4.4.4 (standard issue) 64 bit.
When I installed suse I had only attached one harddisk. A 1.5 Tb hardisk.
In that I had made a 50 Gb partition and installed Windows.
I tried out linux mint, just for the fun, and then
I installed Opensuse, let it erase mint and gave it another 50 Gb In that it made home etc.
The rest Suse also formatted in ext4. Somehow it didn’t get a mount point.

I then attached second and third harddrive, and gave them mount points Windows/E and F respectively. (They are formatted in ntfs-3g)

Yesterday I decided to give it a mountpoint, and gave it /windows/D
I changed my mind and changed it to /home2

In both these places I could access it but only as read only. And most weird of all, it had a lot of files in them, very much looking like root.

My questions are;

How can I access and use that partition?
What might these files be? Can I delete them?
How would I best mount them?

Could anyone help me here?

You must tell the mount command to mount read/write otherwise it defaults read only

show use the output of
mount

this will show what is mounted where

also
cat /etc/fstab

this will show the default mount parameters

You mean like this:

But after failure to read at both locations I took away the mount points.

Where would I best mount it?

4

sdb1 and sdc1 have SFS as partition type, which would be windows dynamic disk, I’m not sure if the openSUSE kernel supports this by default.

sda5, as you have mentioned has no mount point set.

5

windows dynamic disks can be converted to basic with Testdisk, a guide is here /mypkb.wordpress.com/2007/03/28/how-to-non-destructively-convert-dynamic-disks-to-basic-disks/

6

Mm but the two pure ntfs3g drives are not a problem, they have each one extended partition. (that is sdb and sdc, and sdb1 and sdc1)

The problem is sda which has partition sda2, that didn’t get a mount point in the installation.
I made one in yast, putting it in /windows/D
and find that, 1) I cannot write to it

This is Yast expert partitioner now, I once more put the mount point in /windows/D
http://www.imagebam.com/image/c0748d98076270

  1. it contains “root-like” files.
    Why does it do that…?

It shouldn’t contain anything

See here

http://www.imagebam.com/image/f53af398076664

(and I did chose read and write in fstab options, see here
http://www.imagebam.com/image/42a43d98076769

The problem is sda which has partition sda2, that didn’t get a mount point in the installation.

sda2 is the extended primary partition, this is a ‘container’ that holds sda5 and sda6. the space displayed as sda2, is the space in sda5 + that in sda6.
It appearers I misunderstood your posts.

Again, sda5 needs a mount point!

I made a mount point, that is why I can see these files. ImageBam - Fast, Free Image Hosting and Photo Sharing

I put the mountpoint in /windows/D (just to put it somewhere)

I can mount but not write in it, so the 1.25 Gb are basically useless unless i can do something.

And… why would sda5 be in sda2 when that partition were mounted for the first time yesterday…?

Before that i had just the sda2 and sda5 in peace thinking to mount some day. Which was yesterday.

Something is really fishy here…

please do

su -

then

fdisk -l

thats a lower case L, and post the output

also the ‘mount’ and ‘cat /etc/fstab’ requested earlier, seing you have made changes since posting them.

sda5 also needs an fstab entry, you have none, need to add one.
