Burning time too long

OK, we probably found it!

The PIO mode is an old and very slow transfer mode; it is considered a "degraded" mode.

Before attempting the manipulation to fix this problem, I would like to know how many hard drives you have (physically, I mean, not counting partitions) and what type they are (IDE or SATA), just to be sure.

The manipulation consists of uninstalling the primary IDE controller.
To do this, you need to follow the same steps as explained in my first response, but when you get to "primary IDE channel," you choose "uninstall" from the right-click menu.
You will need to restart the computer for this to take effect.
At startup, leave the PC alone; XP will automatically reinstall the IDE controller.
You will see messages at the bottom like "new hardware detected," which is normal.
Once this is done, check again to see if the PIO mode is gone and that DMA is in its place.

You should regain the proper burning speed.

You need to check what mode your burner is operating in:

right-click on "My Computer"
"Properties"
"Hardware"
"Device Manager"
"ATA/ATAPI IDE Controllers"
"Secondary IDE Channel" (if your burner is indeed installed on this channel, which is usually the case)
"right-click"
"Properties"
"Advanced Settings"

There you have Device 0 and 1.
On Device 0, check what is in "Transfer mode"
if it says "PIO mode" that's not good, that's where your problem is.
if it says "DMA if available" and below that you have active transfer mode DMA 2, then your problem lies elsewhere.

It's possible, it may also come from the buffer in Nero.
It should be at least 20 MB.

But if Nero tells you 6 minutes and you take 30, it's a data transfer problem from the disk to the DVD, it might be the SWAP, it could also be that the hard drive it's on is not in DMA mode.

The brand of DVD you are using, was the burning okay before?
Or is it a brand you have never tried?

To find out the DMA mode of your hard drives, follow the procedure I described in my first response, but check the "primary IDE channel" instead of the secondary one.

You should be in DMA mode 5 or 6.

Everything is working correctly. It was my mistake. I tried to insert a DVD-RW that had already been burned.
Thank you for everything, Flo.

Hello,

I know it's an old post but I have exactly the same problem as the others in this post, except that I can't fix anything myself.

I have 2 primary channels for the IDE, and my burner is on the second one. When I check the second channel in the device manager, it says "DMA if available," but in active mode it states PIO mode. I burn very slowly, but the burns work very well anyway (except for the endless time it takes to burn).

Recently, I read on a forum almost the same procedure mentioned above to switch from PIO to DMA (except that it didn't do anything), which said that the only difference was that I had to uninstall the driver for my burner channel, then shut down the PC, disconnect the burner, start up the PC and let it install the now empty channel, and then shut down to reconnect the DVD and start the machine. ONLY this worked for me; when it redetected it, it was once again in active Ultra DMA 2 mode.

My problem is that after managing to switch back to DMA mode, I tried to burn to see if everything was fine again… but alas... the burn went up to 4% quite quickly, but the rest went very slowly. Subsequently, I checked the device manager to see if it had stayed in active Ultra DMA 2 mode... but no!!! It returned once again to PIO mode!!!!

I am lost! I have tried everything I could find on the internet but to no avail!!

Does anyone have an idea on how to make it stable again??

Specs:

Intel Pentium dual core 2.8
Asus P5WD2 Platinum motherboard
2 x 10k RPM Raptor SATA drives
1 Seagate 300 GB 7200 SATA
Liteon burner on 40 pin IDE connector

Hello Flo,
I checked as you suggested and everything is normal. I wonder if it's because the temporary files are placed on the "L" partition (Swap) of my hard drive while my burning software is installed on the "C" partition with Windows, and the other software is installed on the "M" partition.

What is the DMA mode? How can I check? The buffer memory of Nero 6 was 18 MB, I set it to 30 MB. I changed the location of the temporary files of Nero and put them on drive "C". I did a burn and it's the same. I calculated the speed of my partitions with Nero and it gives me 2437 KB/s for "L" and 2016 KB/s for "C". What do you think, Flo?

As for the DVDs, I haven't changed, I use Philips.
I checked the mode on primary IDE channel and I have:
Device 0
Transfer mode: DMA if available
Active transfer mode: PIO mode
Device 1
Transfer mode: PIO only
Active transfer mode: PIO mode

I checked the main IDE channel property in the properties and it is listed as Standard ATA/ATAPI IDE Controllers. Otherwise, I don't know how to check if it's IDE or SATA.
I only have a single hard drive partitioned into 5.

Good evening

I have the same issue with the IDE drive

I am following your responses with interest

Personally, I have 2 IDE channels... is that normal??

For my first one
I checked the mode on the primary IDE channel and I have:
Device 0
Transfer mode: DMA if available
Active transfer mode: Ultra DMA mode 5
Device 1
Transfer mode: DMA if available
Active transfer mode: not applicable

For my second one
I checked the mode on the primary IDE channel and I have:
Device 0
Transfer mode: DMA if available
Active transfer mode: PIO mode
Device 1
Transfer mode: DMA if available
Active transfer mode: not applicable

Thank you in advance for your help

OK big Phil, can you do the manipulation I explained in post 7.

c_kermit, you indeed have pretty much the same issue.
Uninstall the second channel (for you), as explained in post 7

As for me, it's Flo, like Florent.......

Here it is, I did the manipulation. I measured the speed with Nero and it's going 10 times faster. But there's a catch, my burner no longer recognizes my blank Philips DVDs.

thank you thank you and thank you again ... it works perfectly

this forum is amazing ...... 2 bugs fixed in 1 day

thank you and good luck to everyone

Nobody can answer me??? It's important because my hard drive is full and I really need to burn!!!

What burning software do you use?

And which "exact" version of XP?

--
I'm Flo, like Florent.......

Obviously, your version of XP Pro is not a pirated one? Because otherwise, this kind of problem is common.

Have you tried connecting to the second IDE port on the motherboard, and have you had the problem since the beginning or since the install of Nero 7?

--
It's me, Flo, like Florent.......

Unfortunately, the cm p5wd2 premium does not have a second IDE port, so I cannot try that. As for Nero, I've had this problem from the beginning, because it's a brand new PC and the first time I tried to burn something, it took forever.

But I noticed something, I'm not sure if it has any relation but...

When I finally managed to switch from PIO mode to Ultra DMA 2 mode, when I uninstalled the driver of the channel and physically unplugged/replugged my burner, I noticed that yes, the burner was indeed in the required mode, but my PC became very slow! my whole Windows was running at a crawl... and when I tried to burn to test and, probably, it switched back to PIO mode during the burn, my PC no longer lagged.

I'm not sure if this could be related to why it switches to PIO mode, but I'd rather mention it just in case. Personally, it seems to me like there's a conflict when the burner is in Ultra DMA 2 mode, but with what and why, I couldn't say.

A conflict.....possible.

We need to know the exact model of Liteon, most (for at least the past year) are not UDMA2 but UDMA4 (ATA66)

It is sometimes necessary to flash the firmware on Liteon to fix bugs.

It's worth a try.

What would also be interesting to know is whether it's Windows that forces PIO mode or the motherboard's BIOS....

(most of the time, it's Windows, but we need to make sure by checking the BIOS, what do you have?)

--
I'm Flo, as in Florent.......

Your post just lit a light in my head...

You say that recent burners use UDMA 4, which is ATA66... well, that reminded me of something I saw in the motherboard manual.

I don’t believe that the model I have, namely the Liteon model 165H6S, dual layer, is much older than 1 year, so I went back to look in my motherboard manual and I was able to read a passage that said that the primary IDE channel was compatible with DVD-RW ATA 100/66 models. However, I saw a small line at the bottom of the paragraph that said:

''... Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE device''

I thought that the problem might come from there because at first glance, it seems to me to be a pretty standard IDE cable that is connected to the burner, and since I don’t know what an 80-pin cable looks like, I really don’t know if this is the source of the problem. I imagine that if it is indeed a 40-pin cable, then it must not be big enough to work in any mode other than PIO. On the other hand, if I don’t have the right cable, then why does it still work!! It seems to me that a 80-pin cable and a 40-pin cable shouldn’t have the same connector, right??
