I currently us Sonic RecordNow DX 4.61 and personally find it's the best program for making a DATA CD/DVD, so I downloaded and installed the Trial of ONES and made some DATA CD's and burned a few CD-R's in my new NEC 3500, no burn problems so far. Haven't tested DVD yet as RecordNow is burning those fine for now!
Only problem I've noticed with ONES so far is after I've burned a CD-R and exited the program it seems to lock my NEC 3500 in to either 4x or 8x read speed, even after opening/closing the tray. I thought it was the CD I had just burned, but when I opened RecordNow to use the Disc Explorer/drive properties that seemed to reset the drive and the disc then read at full speed?
Apart from that it's been OK!
