Very slow DVD ripping in Windows 7

stephens · 20 Feb 2010

I have installed Windows 7 (Home premium) as a dual boot (with XP) and now as a single boot.
With both setups it takes 2 or 3 times as long to rip a DVD to the hard drive (25-30minutes.)

I noticed in device manager, that for IDE ATA/ATAPI Controllers: ATA Channel 0, ATA Channel 0 & ATA Channel 1 all have "DMA enabled" unchecked.

Should DMA be enabled by default when Win7 is installed? And if so does anyone have an idea why it would be cancelled on a fresh install?

The Pioneer DVR-216D was plug and play and just worked with XP so I haven't a clue about these sort of things. Should I have installed drivers for it when using Win7, or updated the firmware?

Many thanks for any replies.

Sounds like you're stuck in PIO mode.

That can be due to a hardware problem, like an IDE cable that isn't seated properly.

Once that is corrected, you'll need to get the DMA mode running again:

Thanks for the info bobkn.

ATAPI Cdrom says PIOMode4.

What is the correct way to set it to DMA? Do I just check the enable DMA box?

Some say copying dirty disks can set the DVDRW to PIO mode, is that likely to be the case?

The two HDD's and DVDRW are all SATA and I have not touched any cables between XP when it was OK, and installing Win7. I will try reseating the SATA cable but is there anything else to check if that does not work?

Thanks for any replies.

I have since checked the SATA cables and followed the Win7 Help instructions and been into device manager and the appropriate Channel to select ATAPI Cdrom which shows as PIOMode4. Then I checked the "DMA enabled" box and clicked OK.
The window then refreshes and the "DMA enabled" box is unchecked again, so it looks like I cannot change it from there.

The (D945GCNL) BIOS has never been updated because Intel say not to unless problems, and I am not sure if that would help.

Are the DVDRW (Pioneer DVR-216D SATA) completely plug and play or is there a chance that it is not Win7 compatible, or that it needs some Win7 drivers for it?

Many thanks for any replies.

have you installed the latest intel chipset drivers? INF Update Utility - Primarily for Intel® 5, 4, 3, 900 Series Chipsets

Yes hclarkjr I downloaded the very latest Intel Chipset (9.1.1.1025 12/29/2009) for my D945GCNL Mobo/Win7 and installed it first before the other drivers, as per Intel instructions.

It seemed to install fine/successfully and I did a restart, after each driver.

The window then refreshes and the "DMA enabled" box is unchecked again, so it looks like I cannot change it from there.

Then I tried uninstalling the Microsoft Driver for it, re-booted, and let Win7 install the driver again. But it still stays in PIOMode4.
The Pioneer website just says that the DVR-216D works with Vista using the Microsoft driver (no mention of Windows 7.)

Then re-installed XP and it is fine again (DMA is enabled) and the Movie that took 27 minutes to copy to HDD only took 7 minutes.

So the DVDRW and SATA cables are definitely OK.

For XP, the chipset driver I installed was from the Intel Mobo driver install CD, so it is an older version than the latest version I downloaded for Windows 7. I am not sure if using the latest chipset driver could be the problem.
Also there are later BIOS updates for my Mobo but the notes for them don't seem to have anything relevant to this problem.

Has anyone got any ideas that I could try seeing as it is OK with XP?

Many thanks for any replies. :)
