It use to work but now it does not due to this error:
The driver ESDI or ASPI is not compatible. error 80900015
The old version of ESDI are not compatible with DVD Rom.

I tried re-installing ME, also tried deleting the hardware in device manager, tried letting windows recognize it. Tried using New hardware installation.

Try updating your ASPI Drivers?

here's the instructions as well as information that you may need to understand what this product does.  Including the Download for the ME version.  It is free from adaptec:

Let me know if this helps.

I'Ve tried that and I believe its after this installation that everything stopped working. Even Outlook has a hard time starting.

it used to work ?
try this: go to start - programs - accessories - system tools - system restore. choose to restore to an earlier time & try to find a date when you know it was working.
this process can be reversed if it doesn't work but if it does you may need to re-install programs installed since that restore date.

I"ve suceeded in getting the DVDrom to work but now when I Power DVD it tells me that ASPI is not installed and it is. I tried uninstalling Power DVD and re-installing it, still same problem.
When I try to rip that program says no ASPI access for this drive, no ASPI adapter available.

Those Bast... at Microsoft. Remember when you said to update to V4.70 for ASPI, you guys were right but with ME it will not work if ? ASPi was uninstalled or otherwise. What I know is that for me it never worked properly because a file was not installed with V4.70 and will never be because Microsoft wants a hand on everything, no wonder their in court.


Windows ME, 2000, and XP - Microsoft and Adaptec Divorce
After and during Windows 95/98, Adaptec continued to update the ASPI, including support for new CD-readers and writers, and other improvements. However, apparently Microsoft wanted to move away from external, non-Microsoft technologies in their OS, so with the newer OS's (ME, 2000, XP), ASPI wnaspi32.dll and the ASPI layer) is not included as part of the OS. Microsoft includes a minimal "ASPI" (called the Pass Through interface) in these OS's. This doesn't use the standard ASPI calls, so in other words, ASPI is not native to these OS's.

So, Adaptec then adopted the policy of selling the newer ASPI, as part of the EZ-SCSI packages.

This is where things can get a little confusing. Adaptec sells ASPI in the form of exclusively distributing the wnaspi32.dll file. They do make the latest version (4.60, build 1021) of the ASPI layer available for upload off their web site. (See They state this:

"Do NOT install ASPI32.EXE with Windows 2000, Windows ME... If you have one of these [operating systems], you will be using a different aspi layer that will conflict with the one provided in this file." (Emphasis mine)

This is mostly a political statement. 2000, XP, and ME don't install an ASPI layer, nor does it install wnaspi32.dll. SO what does this statement mean? This is meant to discourage people from downloading the latest layer and using it with Microsoft's newest OS's, which were meant to bypass ASPI. What Adaptec REALLY means is "Microsoft is not permitted by us to distribute the latest ASPI layer, because they wanted to do it themselves. Good riddence."
So, you can install ASPI on ME/2K/XP. Here are the steps:

Get all the applicable ASPI files. You can get them from our web site - click here. (Yes, this is illegal. But we are doing it anyway, for now.)
Unzip this file into a temporary directory; follow the instructions in the readme.txt file.
Put wnaspi32.dll manually in your system32 directory, because the ASPI layer installer/updater (aspi32.exe) will not run unless wnaspi32.dll is accessible for the system.
Run aspi32.exe; this will replace wnaspi32.dll if it needs to, and either replace or add the ASPI layer, however necessary to udpate the system.
Run aspichk.exe; you should see the dialog on the right:

I Don't Believe You
Fine, don't. =)

Whatever the case, Translator will soon be available with code that makes ASPI not mandatory to have on your system to run Translator, at least if you are running NT, 2000, or XP. However, it should be said that while the Pass-Through interface is adequate, and does the job at least as far as Translator is concerned, ASPI is still a much better technology, and we recommend that you buy it (EZ-SCSI 5.0 from Adaptec), and install it on your system.

I know I could of just written the web adress but I wanted to empahsize so in case this page goes down, we (all users and experts) at Expert Exchange has a history of this to answer others because what I found by searching the web is that there a huge amount of people hacing trouble with ASPI.

OK no offence but I think you're barking up the wrong tree.
If what you say is correct there would be an enormous amount of DVD drives being returned to the supplier and this is not the case. In fact in the past week I have installed 3 DVD drives without a problem (no updates,patches, changes of driver or aspi.exe files required.
I have a feeling if you did a clean install you would have no problems because your problem sounds more and more like software/driver conflicts.

I agree and the first time I installed the hardware everything was working fine until I disabled in Power DVD the ASPI function and upgraded to Version 4.70 from Adaptec.

I suggest you try it, now that we know how to correct the problem.
