Re-installing Cdrecord problem.
 

I think I may have accidentally done some damage to "Cdrecord" which I normally use with K3b.

When trying to use K3b, it says that it was unable to find a CD writer.
Here are the other commands issued and the results:
# rpm -q cdrecord-2.01-0.a27.3.i386.rpm
package cdrecord-2.01-0.a27.3.i386.rpm is not installed

# rpm -ivhf cdrecord-2.01-0.a27.3.i386.rpm
warning: cdrecord-2.01-0.a27.3.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2
Preparing... ########################################### [100%]
package cdrecord-2.01-0.a27.3 is already installed


# rpm -e cdrecord-2.01-0.a27.3.i386.rpm
error: package cdrecord-2.01-0.a27.3.i386.rpm is not installed

How can I fix this problem?

Thank you for your help.

That will uninstall it if it is already installed. If you keep having problems try,

Thanks to reddazz.
I will remember the rebuild option if I have a similar problem. I have been suggested to use yum and this solved the problem.
