I have a compaq presario, 700mhz, 20gb harddrive( approx. 11gb free),448mb ram,( approx 80% free on startup), and 40x max compaq cd-rom drive. I installed my first cd-rw drive, a sony crx185a1 and tested using promedia 32x cdr's to record to. I used the Bs Recorder Gold Wizard's "Disk Duplicate" using their defaults. I tried 3 different source discs, a studio recorded one done by my son who has musical aspirations and two commercial ones. All had the same result, the 3rd an 4th tracks were blank. The rest was perfect. Anyone have ideas for correcting? Thanks for any help you can give me.
