Ok, I just purchased a Sony DRU-500a drive and haven't had any problems burning dvd's, however this is what happens when I burn CD's...it powers thru like the first 7-10% of it and a good clip, and then it just sits there for a while (almost 1 min or so doing nothing/spinning not burning) and then spins down to like 1x and then only speeds up to 4x!! What the hell is going on?? In simulation mode it runs fine!!
I have a P4 2.0A GHZ computer with 1024MB of DDR RAM and an 80GB HDD (with at least 10GB free) and there's nothing running in the background. I use Win XP Home and I tried using both Roxio EZ CD Creator 5.0 Plat and Nero 5.5.10.0 (both show fine simulation but actual burn screws up). The quickest I managed to get was like just under 9 mins for like 680MB which is pathetic (something like 1/4 of how fast it should be). DMA is on, the drive is the master on its channel (and I'm not using the other device, it's reading off the HDD). I've tried it both with Power-burn on and off. The media I'm using is Memorex 700MB cd'rs which I KNOW are capable of faster than 8x at least. So before I rip this POS out and return it to best-buy can someone please help??? Also, Nero's CD Speed gives me an "Invalid Field in Parameter Test 052600" if I try and do a transfer test. (Although in Nero's and EZ CD Creator's simulation it gets 24x).
It looks like it works fine but when it tries to fill the last part of the buffer or something it's having trouble?? I have no idea, it burned fine at 2.4x for a DVD+R
