I posted in the Newbie Forum yesterday with this problem and another question, but I think I need to post here now about my DRU-820A slowness.
I recently got the drive (first DVD burner :o) and had just burned some CD-RWs and DVD-RWs, and now am wanting to do +Rs. The 2x DVD-RWs worked as I expected, taking 30m. My +Rs are 100 Fujifilm 16x, which are identified as PRODISC R05. Of course I left the first one set to 16x in Nero (18.104.22.168) and it took an hour and a half! The second, and last, I set to 8x speed and it “only” took 48 minutes. Also, for both burns the Buffer Level dropped below 50% every 1-2 seconds (Nero’s Read Buffer is always at 100), is that supposed to happen? It never goes lower than 95% with the DVD-RWs or CDs…
It was on an ATA-33 connection, since I was using a 40-wire cable, and I figured that 33MB/s should be enough for 16x; although I’m not sure if it runs at the full speed with my VIA Apollo Pro133A chipset.
I was wondering if it needs to be ATA-66, so I found an 80-wire cable to use instead. Now the BIOS warning is gone about “using a 40-wire cable” and the BIOS screen says it’s in ATA-66 mode. In Windows, Device Manager still just says “Ultra DMA Mode” as before – I don’t know if it’s supposed to differentiate between DMA modes or not…
I haven’t tried burning another +R, but I checked my ripping speeds again and CD-DVD Speed benchmark, and it’s no better than before. Using the DRU-820A OR my 6 year old Pioneer 16x reader (ATA-33), DVD Decrypter only shows ~3.5x speed. Similarly, in CD-DVD Speed, reads are only 6-7x max (actually, I think the old Pioneer performs better in the few comparisons I’ve done), whether using -RW, the +Rs I made, or a pressed DL. Shouldn’t I be getting speeds around 16x like I see in the CD Freaks reviews? (I know not all types will be that fast.) BTW, for the Interface Burst Rate, it only shows 10/17MB for the Sony/Pioneer. That doesn’t seem right?
I just don’t understand what’s going on. Why are my burns/rips/reads so far off of what they should be? PLEASE help me get it working right. Here’s my system details so you hopefully aren’t wondering.
Dual 930MHz PIIIs
2 Hitachi T7K250 drives (8MB, 60+MB/s) on Promise ATA-100 controller
Sony burner, like Pioneer reader, on its own channel on VIA IDE controller
Thanks in advance for any help!
