View Full Version : Why is my 32X burning sooo slow?

I have it hooked up as secondary slave while my 52X reader is secondary master. When I put a CD in the 52X to burn to the 32X burner it is really slow. This is using Nero. Maybe I'm not using Nero correctly. Any ideas? Thanks.

For one, you should use the Hard Drive as a buffer. There's an option to write the image to a HDD before burning to a disc. I suggest you do that. Just because you CAN write on the fly doesn't nessecarily mean you SHOULD. =)
Secondly, check the speed of your CDR's. If they're less than 32X, they're not gonna burn at 32X.

I have a CD-Rom claiming to be 52X, but in fact it's like 20X reading data files, it's faster when reading audio cds, but who needs to read an audio cd at 52X anyway?
they are both on the same ide chain... thats part of your problem. i have both my dvd and cdrw on the same chain and the burnproof kicks in a few times every cd copy. but i still manage to copy full 700mb cds in about 4-5 minutes.

I had the same problem with my 32x CDRW when i had it and the CD-rom on the same IDE, try and have the one on IDE 1 and the other on IDE 2. This way there is not so much data been transfered on 1 IDE cable.
PS: i am also using Nero.
the best configuration i can think of is to have your hard drive and your regular cdrom on ide1 and the burner on ide2 which accomplishes two things. makes it to where your cdrom and cdrw are on different chains and also makes the hd and cdrw on different chains which in both cases will make transferring information to the cdrw much faster meaning less burnproof cut ins or none at all.
try that and post whether it worked for you.

Aren't CD-ROMs ATA33? That would take the HDD down to ATA33 too... =\

nope. the speed of the different drives makes no difference. even if it could the difference would be very negligable seeing as how most hd's transfer in the low 30's anyways. just make sure you are using an ata133 cable on your ata133 drive and the cdrom and there will be no difference.
the ata speed is still 133mb/s the cdrom just can't match the speed of the hard drive.

No, now I know for a FACT that when you put an ATA33 and ATA66/100/133 hard drive on any IDE channel, that channel will run at ATA33, no matter what the other drives are. The channel must revert to the speed of the slowest drive in order to be compatable with both drives.
I would assume it works the same way with CD-ROMs, but I don't know for CERTAIN. Lets have someone else's opinion.
And as I understand it, ATA66 and faster HDD's run in the 50-60MBps range, not 30's.

the best set up i have found is cdrw as master on secondary. Hdd, as master and cdrom or dvd as slave on Primary. Using Nero.

the 8mb wd is the fastest ide drive on the market and this benchmark (http://www.tomshardware.com/storage/02q1/020305/wd1200-04.html) (granted its from tom's) shows the max speed doesn't even pass 50 mb/s and averages 40 mb/s through the entire medium.
and hardass's setup he likes is just what i suggested.

Alright, sorry about that one, but putting a CD-ROM on the same channel as an HDD will limit the HDD's performance by something like 37% (45MBps HDD multiplied 100% divided by 33MBps CD-ROM). That better? =)

well i'm not 100% sure that it reverts to the slower drive... but i could be wrong.
but if hardass is saying its faster the way he has it then surely its not limiting hard drive performance.

On one of the forums awhile back they did a test to see if having a cdrom and hdd on the same ide made the hdd run at the cdrom speed. It did not, granted it slowed the hdd, but the amount it slowed it was not enough that anyone would notice without measuring devices. I have run mine this way for years and have never noticed a slow down when DVD is being used.

I did the same test here and it showed the same thing. The only time the hard drive slowed to CDROM speed was when transfers between that CDROM and HD took place...this would be common sense though. When placing two different ATA standard drives on the same controller, only one drive at a time can occupy that channel. IDE channels can "switch" between the two due to this.
You can actually see this for yourself in the BIOS. When IDE devices are detected it will list what mode the device is in. If you place two different ATA standard drives on the same cable, they will be detected at their relative mode and act that way when the device is active. If using both drives simultaneously (besides copying CDROM to HD) then HD performance will take a hit but only because the channel becomes saturated with data. The same thing happens even when two HDs are on the same channel (not quite as bad as a CDROM and HD being on that channel though).

It was probably your post I read, Thanks Jon.

Have'nt retested yet. When I do I'll post results.

If Hardass has a 32x burner, it's going to be ATA66 compliant. Anything past 12x or so I would think would be ATA66. Which in that case it would be fine with even a WD drive.
Also I'm not sure if this has happened to anyone else, but with my burner and dvd on the same ide cable, I can only have dma enabled on one of them and it works fine when I have the hdd and dvd/burner on the same channel.
Just something I noticed that may explain why you burner is going slow, it could be in a pio mode rather than dma because of this.
