K3B error – Please insert an empty or append-able Double Layer DVD+R medium

If you use K3b for the first time, you will get confuse this error. You think that you have put your write able DVD disc inside your DVD writer but why K3b still says that there is no disc inside.

This error occurs when you try to burn a DVD with more data that it can hold. For example, if you see on the screen below, I try to burn 7.3 GB in a standard write-able DVD disc with at 4.7 GB capacity. It mentioned that I still have 630.8 MB free space. The color bar is still green.

Seem that everything is alright, but it is not. K3b doesn’t recognize your DVD capacity. If you use a standard DVD writer then it will be no problem because the default size is 4.7 GB.

But, if you use a Double Layer DVD writer then it will be a problem because the default capacity is 8 GB. So, whether you put a standard DVD disc or a Double Layer DVD disc, K3b will always recognize as 8 GB capacity. As long as you know your DVD disc capacity then it will be no problem.

Not enough space at my External Hard disk

I got this problem when I try to back up my data from my laptop today. Suddenly, I got not enough space message. FYI, my external Hard disk is Maxtor Personal One Touch 100GB.

So, I checked the hard disk space left.

taufanlubis@toshiba:~$ cd /media

taufanlubis@toshiba:/media$ ls

cdrom cdrom0 Maxtor sda1 sda2

taufanlubis@toshiba:/media$ df -h Maxtor/

Filesystem Size Used Avail Use% Mounted on

/dev/sdb1 94G 93G 367M 100% /media/Maxtor

taufanlubis@toshiba:/media$

Then I started deleting few gigabyte of my files to free up the space. I surprised because there was no change in Free Hard disk space (still 367M) at all. After searching for a few minutes with File Browser, finally I found out the problem which is a ‘Trash Bin‘ inside my Maxtor.

I though the Trash Bin is only one. Is it the default of Ubuntu? Don’t know yet.

I haven’t looking for the answer. Next time, may be.

Well, then I opened the .Trash-taufanlubis (trash bin directory), delete all the files inside.

Check the result.

taufanlubis@toshiba:/media$ df -h Maxtor/

Filesystem Size Used Avail Use% Mounted on

/dev/sdb1 94G 61G 33G 66% /media/Maxtor

taufanlubis@toshiba:/media$

I got my space back.

Virtual Box Error – A Domain Name Server (DNS) for NAT networking could not be determined

A Domain Name Server (DNS) for NAT networking could not be determined. Please, check your /etc/resolv.conf for nameserver entries. Either add one manually (man resolv.conf) or ensure that your host is correctly connected to an ISP. If you ignore this warning the guest will not be able to perform nameserver lookups and it will probably observe delays if trying so.

This error occurs when your Virtual Box’s guest try access internet but the main Operating System’s DNS hasn’t been set yet. To fix it, just add your Internet Service Provider (ISP)’s IP to your DNS.

In Ubuntu, the DNS file is /etc/resolv.conf.

Open System > Administration > Network > DNS and add your ISP’s IP to ‘DNS server List Box‘ then refresh the connection.
