Failure to see DVD drives

[Magician]

Does anyone know what this pop-up means?

 

It comes up twice, on for each DVD drive I have in my system and then tells me that there are no writeable DVD drives in my computer. The drives are ok (As far as I know) I can burn successfully with them via Nero.

 

Its a SHW-1353 (I think thats right) LG drive

Windows XP Home SP2

 

And I have burnt many DVD successfully with imgburn, but all of a sudden its started to play up.

 

Any sugestions would be most welcome.

Stop switching the I/O to ASPI, put it back on SPTI.
