iBook no longer recognises CDR/DVD-ROM drive

[jpheloung]

My TOSHIBA DVD-ROM SD-R2515 (professionally installed) has worked fine for 2 years using Toast Lite 5.2.2L.
After an IT fella at work upgraded my iBook G3 to 10.3.9 my discs would fail partway thru burning.
Now I get the classic 'Error: 0x80020025' when I insert a blank disc - I tried the 'relaunch Finder' fix but no result.
The burner is in there and has worked perfectly. How can I get my iBook to recognise it again?

iBook OSX 3.9 500 mHz PowerPC G3 256 MB SDRAM

I would be tempted to download and install PatchBurn at
www.patchburn.de
It wont hurt
