Today after a month I needed to burn a Back-up on DVD format..
It took 32minutes for 4.2gigs.
I then tried burning a CD took 5minutes

While burning the disk my PC get so slow....

Last time I burn an DVD took 5minutes and CD 2minutes(thats after a week of reformating)

Am using Nero 7.

Any solution or a Reformat needed? (Windows after all).
I tried Kubuntu9.04 Did not like it.... So yah still on Windows XP:(

Any advise.
 
was the backup thousands of little files? that can take longer, also the DVD speed can vary (if its a RW it will be slower).

nope, using DVD+R 16X 4.7gigs

They 820files non compress 4.1gigs. IF compress with WinRar it 1.1gigs.
 
Hi Ismail TM,

The writing speed depends on the DVDs writing speed. How much speed have your DVD.? If your DVD has low writing speed then DVD-RW automatically selects that speed by default. You can't make it higher. So, first check the speed that your DVDs have. OK..?

16X. My DVD supports 20X...

I formated PC and it working fast again. 6mins for 4.3gigs DVD.

Wonder what have cause this everytime? Is there a way to maintain speed?
 
Howzit guys.

I actually have the exact same problem at the moment with my father's pc.

For months after it's first install all was going smoothly and speedily. A DVD took about 5 / 6 minutes to complete, and computer ran fine, like it should. Then suddenly one day it slogged along for 30 odd minutes writing a DVD, and has carried on, taking at least 30 minutes, ever since. Quite a change! Nero says the disc will be writing at 16X, but still takes half an hour, which clearly isn't. And programs take eons to install from a disc as well.

The writer is an LG 20X non-LightScribe IDE drive.
My wild guess would be some driver (corruption / change / incompatibility) issue maybe, but who can really know. I think a re-format and fresh install should sort it out, like has happened for you, Ismail TM. It's just a bind to back everything up (especially with the DVD writer in this state), reload and get it up to scratch again when it's supposed to be working in a business. Will get to it one day...

yep the same but mine LightScribe.
Work fine after the format. took 2hours to format a redo everything.
 
Good thanks. :)

Ok, that's great! Hope it isn't an issue with LG drives. They're supposed to be one of the best.
But guess it'll remain a mystery. At least one that we can fix! :cool:
 
I'm fairly sure your problem has to do with PIO vs UDMA. I've seen this problem LOADS of times and each time it was the same issue.

When Windows encounters an error reading a disc, it assumes it's because it's trying to read too fast. So it lowers the bus speed, but only until the next reboot. If it encounters further problems, it locks the bus speed at the lower rate. Each time this happens, Windows lowers the bus speed further, until it hits the minimum: PIO.

This problem is fixable without a reinstall: google for more.

To check this, check your primary and secondary controllers in Device Manager. They might be set to "DMA if available", but it'll also show the current transfer mode.

The solution is also on MyBB somewhere - we have discussed this before. Definitely no need to reinstall OS.:D

Thanks. Both already set to DMA if Available.

Explain the difference between PIO and DMA?
 
Yip, defnitely was changed to PIO, which is dog slow. Uninstall your IDE devices on Device Manager and reboot your PC and when XP restarts, it will auto-detect the IDE devices again and it will set it to UDMA.

If it does not work, then follow the above steps but switch off PC, unplug the cables from the device, reboot then shutdown, plug cables back and boot up again!!

Ooookay. That makes total sense!
So instead of slowing down the disc speed, Windows slows down the entire bus speed. Nice. :rolleyes:

Oh boy, Device Manager won't even open and gives a missing dll error.
Guess a reinstall it is then... :erm:
The pc has been going solidly for a year or so, so probably about time.

Thanks alot for the help, guys! Learnt something very useful. :cool:
 
From Wikipedia:

Without DMA, using programmed input/output (PIO) mode for communication with peripheral devices, or load/store instructions in the case of multicore chips, the CPU is typically fully occupied for the entire duration of the read or write operation, and is thus unavailable to perform other work. With DMA, the CPU would initiate the transfer, do other operations while the transfer is in progress, and receive an interrupt from the DMA controller once the operation has been done. This is especially useful in real-time computing applications where not stalling behind concurrent operations is critical. Another and related application area is various forms of stream processing where it is essential to have data processing and transfer in parallel, in order to achieve sufficient throughput.

That explains why it's been almost impossible to do anything else while writing a DVD. :eek:
