The Arabic Shaikh al-Albaani website has produced a free DVD of the Shaikh’s Al-Hudaa wan-Noor series of tapes. The DVD includes 901 tapes. The size of the file is about 4.18GB, once you’ve downloaded it you have to burn it to a DVD for it to work.
You can actually search through the tapes by typing a particular word you may be after, which is quite handy. As an example, if you searched for, ‘النووي’ it would give you all the recordings which have the word ‘An-Nawawi’ listed in the cassette titles.
You can find the download link here. [Update Feb 2015, this link no longer seems to be working and I haven’t been able to find a replacement.]
