IDE channels are for internal burners. Your external burner is on a USB bus. Also, Nero does install its own aspi. Have you tried a different external enclosure?

laddyboy, thanks for the response.

With respect to the enclosure, I was using a Bytecc Me-320x with my internal burner. When this issue arose, I wound up buying an external burner and lo and behold its in a Me-325x. I assume slightly newer model of same manufacturer. Unfortunately, it provided no success in aleviating the problem.

mwafb: I have had a Memorex 4x (Pioneer), NEC 2500a, and NEC 3500AG burners mounted in external enclosures. Only once did I have a problem with the NEC 2500a. I had to change enclosures and do a clean reinstall of Nero before I could get it to work correctly again. It had worked perfectly for 8 months. It was also in a Bytecc USB2 enclosure. I now have it mounted in a Plumax USB2 enclosure. I have the NEC 3500 mounted in a Plumax fw/USB2 enclosure. I also have the external USB2 version of the Lite-On 1633. I also have several USB2 hard drives and other USB devices that are attached to my Compaq Athlon 64 laptop. Everything also works on my Toshiba laptop as well.

I tried replacing the dvd burner (pioneer dvr-108) with a Nec cd burner and now it actually works. So the problem occurs only when I use the DVD burner in an enclosure connected to usb 2.0.
In other words, I have been able to burn a cd over usb 2.0, got the dvd burner to work when installed internally on my desktop, and I got the enclosure to work when I replaced the dvd burner with a cd burner.
But, as many of you have experienced, using a dvd burner in an enclosure over usb 2.0 does NOT work.

Hey, does anybody have another OS's? Has some of you tried to burn a DVD with another OS's rather than Windows? I say this cuz I tried with freebsd and I couldn't burn any DVD, this means that te problem is not from the software, it's from the hardware (external case's chip and similar).

i have tried every single thing mentioned in this thread under sp1 and sp2 of windows xp, NOTHING fixes it, i am on a compaq presario 2100us laptop and i am using a lite-on 411s, i have a bytecc me-320x enclosure usb 2.0 connected through a buslink usb 2.0 hub, the drive works fine internally, the external works fine with a hard drive or cd writer. all my drivers are up to date, i even tried that dell patch to no success and had the same o2 controller, all software fails, the new Nero 6.6.0.6 does not work with it either... i guess at this point my suggestion is to get a new damn enclosure, b/c this one plain doesnt work burning a dvd-r.
now, what enclosure should i get :)

I have a Plumax PM525C2-PPB firewire/usb2 combo enclosure that I'm using with a NEC 3500AG on a Compaq Presario R3000 Athlon 64 3000+ laptop. I also have a NEC 2500a in an older Plumax USB2 enclosure that works fine as well. Your mileage may vary.

"Has everyone tried unchecking the "DVD High Compatability Mode" as suggested by Craig at Nero?

For several days, I kept getting the same error message everyone on this thread has been receiving. I unchecked the "DVD High Compatibility Mode" box (under "Recorder", "Choose Recorder", "Options", then "OK"), and now I am able to burn with no problems at 8X.

Now that I have unchecked "DVD High Compatibility Mode", my DVD burner is working smoothly. "

Where do I go to find "Recorder" to start? I searched everywhere and can't find it.

mwafb: It's one of the menus in the Nero Burning ROM program, not Express. If you have the full version and are using Express, just click the "Nero" button to go to Burning ROM.

I think I figured this out.

I have a MD-16XDVD9-EXT drive that has a NEC ND-3500A drive and a USB controller with the ALI M5621 chip set. DVD+R DL, DVD+R, CD-R media worked fine. DVD-R or DVD-RW when burning DAO (No Multisession) would fail. In DVD Decrypter I would get semaphore timeout errors. In Nero I would get (SCSI_ABORTED) and (SCSI_HASTAT_REQUEST_SENSE_FAILD) errors. From reading all the posts it seemed that when people took the drive out of the USB enclosure and put it in either a Firewire enclosure or on an IDE bus everything worked. I tried both and found that everything worked great. My last experiment involved connecting the drive to different USB 2.0 controller with a different chipset. The card I used was based on the Oxford OXFW911 chipset. It worked perfect!!!

I would contribute a lot of the problems that people are having to the ALI M5621 USB 2.0 controller chip used in a lot of USB enclosures. I do not know if it?s a hardware problem with the chip set or a software incompatibility problem with windows drivers.

If you are having these problems can you post the chipset of the USB 2.0 Controller that your enclosure is using? I hope this helps.

The Plumax PM525C2-PPB 1394/USB2 enclosure uses the Prolific chipset. This is one of the enclosures I use. This site does a good job in noting the chipsets used in enclosures.

jd: I didn't see where it specified the chipset. I have a feeling that box uses the Cypress chipset. I may be wrong but I think the Prolific chipset is only available with the 1394/USB2 combo enclosures. Why not go for the combo? Chances are your next system will have firewire as well. Here's another site that specifies chipsets:

http://www.dealsonic.com/plumax.html

You might try googling external enclosures to see what other people are using and their experiences. There is also a forum that discusses external enclosures at:

I would say that the USB 2.0 controller chip is the problem for ALL the chipsets in this thread!

I highly doubt it is the problem for Ali chipsets predominantly.
USB 2.0 enclosures appear to be universally problematic if you do a quick google search.

With my Syba/Creative I/O enclosure the Myson chipset refuses to burn any kind of media with USB 2.0. It will burn disks at USB 1.1

The strange thing is that the .DLL file listed previously did not cure my burning woes with my Pioneer 106D but it now works perfectly with a NEC2500A.

I'd still like to know what exactly the .DLL file does as the NEC2500A did not work in the enclosure before the .DLL file was installed?

I still believe that Nero etc is not the root cause of the problem but for some reason the .DLL file circumvents the problem for the NEC at least?!?

I came to conclusion based on trial and error.

I was using an IBM T42 Laptop with Win XP SP2, USB2, Nero, an ALI USB to IDE controller, and a NEC 3500A drive. With the ALI controller I received (SCSI_ABORTED) and (SCSI_HASTAT_REQUEST_SENSE_FAILD) errors. With the exact config except using an Oxford controller in place of the ALI controller everything worked. Nothing was changed except the controller.

As I said before, I don't think it is a software problem, it's from the hardware. I have an ME-525U2 enclosure with the Genesys GL811E chipset and I couldn't burn any DVD with USB 2.0.

I think there's no solution for this, maybe updating the enclosure chipset firmware could do something useful.

Yes I agree that it would help if the chipset firmware could be updated as my USB 2.0 devices for MP3 player etc work flawlessly.

If nothing worked with USB 2.0 then it might be the actual USB port/drivers as this isn't the case it is a conflict between the enclosure chipset and the USB 2.0 standard.

Now, why the .DLL file sorts this out for one of my DVD drives is a mystery. If we knew what the .DLL file actually does I think that might help solve the root cause of the problem?

Yes, it would help knowing what exactly does the .DLL file, but I think the root of the problem is the synchronization between the DVD-RW drive and the USB 2.0, you can verify this because the enclosure doesn't fail with a hard disk.

All that we are doing with the modified Nero MMC.DLL file is ignoring the 'SCSI Command Error' message the first few times and re-issuing the command a few more times in the hopes that a connection will occur.

Well, there's more to it than that, but that is basically accurate.

It sucks! :-)


Seriously though, we suspected a hardware problem from the very begining. And our 'patch' only confirms that.

Can we say with 100% that its the chipset in the external chassis? No.

Some replace the USB chassis with another and it does resolve their issue. But others try the same solution and it does not work for them. Of course they have different model recorders.

But then others have tried different model recorders with different external USB 2 chassis and still they could not resolve the issue.

The problem is that there is no one solution that works 100% of the time, not even 90% of the time.

The only way this will get resolved is for Recorder MFG's and the Chassis makers to take it from here and try and isolate the problem. It does not matter who's software they use, as it occurs with everyones software.

And only pressure from the Recorder MFG's user can make this happen.

Let me ask a question--my problems are with an internal drive Sony DRU-500A--so it is not just the enclosure.

Craig: How can it be hardware if all the people on this thread are having problems with a myriad of different makes? Don't mean that as a hostile question--your input is very valued here. My next question to you, is why is it that so many of us here were burning fine until this past summer? For some reason, that doesn't sound like hardware to me. Lots of different burners work fine, then suddenly go kaput. Am I missing something?

My last questions is why so many on this thread are using external burners? Is there some advantage? Originally I was going to buy an ext., but my computer guy said internal was faster.

Many thanx to all who have contributed--this really is a special community of strangers.

Best wishes to all for getting this sorted out.
