How can i fix my Toshiba RD-XS30 ?

Hi,

My problem is with the RD-XS30 hdd/dvd recorder, purchased in 2004 only recently the check disc dirty or damaged error message keeps coming up and i am unable to copy to dvd -r as enter blank disc appears. No problems with the HD but i have content that i would like to transfer and not being able to watch dvds is also a pain..lol I have also noticed there is now a clicking sound when the disc is trying to read...any advice or solutions would be appreciated.
