Slow Burning problems with NEC 3500a

I just bought a nec 3500a dvd burner and it is taking me over 2 hours to burn a dvd at 8x with 8x DVD +R’s. I use nero and DVD shrink. What am i doing wrong???

could be DMA is not enabled. u do not give any system info. try these steps also

  1. go through the 10 points listed @ [ you may not be a newbie, but the trouble is, and might be related to one or more of the listed items ]. note: very important to keep the transfer mode on IDE channels in DMA mode. check them every now and then as the transfer mode can change without you being notified. see this MS article

  2. a) know your drive’s capabilities. use nero info tool to discover them. also go to the drive maker’s website and find out what media types and brands, and at what speed to those media types, the drive supports. [ eg., my pioneers 107d & 108a can burn to dvd-rw @ 4x without trouble, but my optorite 401 can only burn @ 2x to dvd-rw even though Nero and other burning programs will allow the drive to burn @ 4x and will produce a “successfull” disc @ 4x…but the result is a coaster ] b) update the firmware of the drive. check for updates @

  3. a) try another brand of CD/DvD disc. b) try burning at lower speed. eg., don’t burn at 24x to 16x media; burn according to MEDIA speed limits, don’t try to burn at the cd/dvd drive’s max speed until you are certain that you can do so without negative consequences.

  4. a) disable and/or uninstall any virtual drives. b) install an aspi layer. preferred is v460. get it @

  5. a) update the burning program you are using to the latest release. b) uninstall any recently installed software. c) do a virus scan, and a scan with spybot s & d [ get it @ ]

  6. for XP or Win2K users, optimise your operating system Services for best system performance. for info go to and

  7. before burning, open taskmanager and shutdown ALL unneeded processes that are running. DON’T commence a virus scan or a defrag before or during a burn - sadly, i have seen it happen !

  8. a) try another burning software and see if you get a better result. deepburner standard is free. get it @ b) for users of alcohol 120%, update to the latest drives support DLL [ look for topic “Alcohol 120% Device Support Patch Released” @ ] c) if you have multiple burning softwares installed, uninstall them all, then install one. test it. install another if needed. test it, and so on…

  9. make sure mainboard chipset drivers are up to date. make sure all cables and jumpers connected to drives are correctly configured with regard to master/slave setup.

  10. enter your BIOS and disable anything you don’t use. set memory speeds to default. set cpu speed to default. if you overclock, DON’T [ until you are certain that overclocking is not the cause of the trouble ].

  11. if you still cannot fix the problem, try the drive or the CD/DvD disc you are having problems with in another PC that has no burning issues [ if possible ]

  12. Disable autorun…unless you really need it for some purpose. for XP users go to start/run/type REGEDIT.EXE then click OK
    press Ctrl+F, type NoDriveTypeAutoRun in the box/find next
    doubleclick the highlighted key and replace the HEX value with b5
    repeat for each NoDriveTypeAutoRun key found. reboot.

It is definantley my computer that is the problem. I tried it on my friends computer and it worked. I have DMA enabled and everything like that. What do i have to get to work on my comp?? Should i reformat everything? I have a HP pavilion ze4800 laptop

you’ve haven’t given any details about what’s happening while the burning is going on, so whether or not your buffer is fluctuating plays a huge part in diagnosing the problem.

The burner does fluctuate drastically while i burn. Everything is normal except that it takes 2 hours to burn a movie

if the buffer keeps fluctuating, then either your computer is underpowered or something like DMA isn’t actually enabled (ie: it might be set to “DMA if available” but the actual mode might still be PIO).

then how do i make DMA the actual mode instead of PIO? My comp isnt underpowered since my other computer i tried it on is basically the same.

What do you get with a simple CD-DVD Speed diagnostic program reading clean pressed DVD? What do you get for Burst Rate, and CPU % utilization? You have laptop, so how you connect the burner?

To get DMA you may need to remove the IDE definitions in Device Manager and reboot, so it will be restored, search for a more complete description.

I connect through USB which is not a problem. Not sure how i run those tests that you told me to.

External USB might very well be of some problem albeit not as severe as you experience, search the forums.

I was refering to Nero CD-DVD Speed, get it here

First just test reading transfer rate on clean pressed DVD-Video. This will normally be “as good as it gets” for your reference. Look at the rate, burst rate, and % CPU utilization.
If you want, you can use the Create Data Disc command to write to blank media and see how the external case handles the speed.

BTW, are you on USB1 or USB2, this is big difference.

Here are the results of the nero speed:
Average: .55x
Start: .5x
End: .57x
Type P-CAV

Seek Times:
Random: 128ms
1/3: 163ms
Full: 266ms
CPU Usage:
1x = 100%
2x = 100%
4x = 100%
8x = 100%

Bust Rate: 0 MB/s

I have usb2

Very bad, the 100% CPU utilization is suspect as If I recall, not even on PIO mode you get 100% utilization at lowest speed test. For good DMA it is ~10%, not sure.
Burstrate of 0, hmmm, as if the USB link is clogged and not moving data.
Do you have other USB devices and they work fine (actually mouse is very slow device so not a good indication)
Something is wrong with the USB setup either in Windows driver and device manager, or the controller on the motherboard, or maybe you have another USB port or can borrow PCMCIA USB card just for testing, or the cable, that you should replace and try again.
That is assuming you said that on a different laptop the SAME external case with the burner works. Search the forums for problems with external enclusures, some poster experience slowness with certain chipsets and/or firmware, but definately not reading speed of 0.5X

You need to isolate the weakest link.

as Goudo stated, there’s definitely something wrong with the interface between the burner and your computer. i’ll move this to the recording hardware forum (where this thread probably should’ve gone in the first place).

mostly its due transferspeed to the drive the problem, so you get many buffer underruns, Ultradma must be ultra dma mode 2, have payload on cpu means it cant keep up the data transefer, so slow it down to a lower speed, defrag you drive, make sure the drive is not hooked up on the same cable as your burner

I reformatted my computer and a note came up saying that a Hi-Speed USB attached to non hi-speed hub, The USB mass storage device is a hi-speed usb device and will function at reduced speed when plugged into a non-HI-SPEED port. There are no HI-SPEED USB host controllers installed on this computer.

I assume this is why my burner has been going slow. What to i need to buy for my laptop to have a hi-speed usb connection?

That’s why I asked if you have USB1 or USB2. You have to be sure what your laptop has, you must read the specifications and if you need special drivers from the manufacturer because it is not standard in Windows. Maybe you have toll-free service or email to the laptop manufacturer and ask about hi-speed USB. Maybe you have defedtive USB controller on the motherboard.

Maybe by chance look if you have Firewire port on the laptop and change the external case to FW, or see if using some PCMCIA card that has USB2 on it.

I bought a usb 2.0 card and now when i burn with dvd shrink or any other program it stays on writing lead in and doesnt go anywhere. What should i do? I ran the nero dvd speed test again and it is up to 6x

Did you try a new usb cable? you might be using a bad cable.

The usb cable works fine

make sure the usb card is installed properly. If that does not work, check and see if their are any driver updates for the card --either by the manufacture or through windows updates.
