Thanks, that solved it.

Now I've encountered two other probs:

How do I format and mount for example hda4?
How do I mount a swapdisk?

To format a partition you can use a format command form the command line. Depending on what file system you want to use, there are different commands. Here is a good link about that:

http://www.lissot.net/partition/

The swap partition can be formatted as swap, but can also be left empty as long as the swap flag is on. You need to turn swap on with the command swapon, but usually the OS does this as it boots as long as it recognizes that you have a swap partition.

Thanks for the quick reply

I have a swap, but on the desktop it says:
Swap Used: 0/0 - %

So I did mkswap -c /dev/hda3 and swapon /dev/hda3 and it works.

I haven't tested if it will work after reboot.

The link describe very well how to make partitions, but how do I mount one?

Also, is there any good site for linux beginners or a description of the linux system?

FYI, the swap will only be used in cases where an application needs more memory to run than you actually have in RAM.
You can mount a partition, as super user or root with the mount command like this:

Code Sample

sudo su
mount /dev/hda7

To unmount use:

Code Sample

umount /dev/hda7

Notice it's "umount" not "unmount"
A way that is easier for beginners to remember in DSL is to right click on Emelfm and choose as super user. Navigate to the /mnt directory and open it. There will be a list of your media partitions there. Right click on the one you want to mount and choose mount.
