as an Xp usser my 'CDVDW SH-S223F SCSI drive worked well. This enabled me to copy DVD-RAM dvd's onto DVD-R/W etc. since installing Windows 7 I am unable to do this, and even if I re-install Xp; am still unable to 'see' DVD-RAM dvd's. I have used used W7 update drivers facility to see what this made of the problem, and it said I was up to date. Anybody have any ideas.
