[QUOTE=cholla;2538639]I don’t know if this will help . I downloaded this program from MS .I got it from one of the links in your posts atsocial.answers.microsoft.com .
The CD drive or the DVD drive does not work as expected on a computer that you upgraded to Windows Vista
Not applicable â€“ I would never upgrade to Fester :-0
I think you rejected it too quickly. It links to a download for Devcon utility
For more information about the filter drivers that may be loaded in Windows Vista, run the DevCon program. To do this, follow these steps:
Obtain and extract the DevCon program. For more information about how to obtain this program and about how to use this program, click the following article number to view the article in the Microsoft Knowledge Base:

If you are prompted for an administrator password or confirmation, type your password, or click Continue.
At the command prompt, change the directory to the directory to which you extracted the DevCon files.
Type [B]devcon stack gencdrom[/B] , and then press ENTER.
This listed my drives & it may list your missing drives.I only got it last night & have only had minimum time to fiad out what it does. If it does list your drives it at least shows your OS can see them .
You list of what you have tried is fairly long .I do remember reading something here at club.myce that was different than what you tried but it’s been a while & I need to see if I can find the topic.
I haven’t had the problem you are having but have ran across a lot of the links in your posts .Trying to find out why my Vista OS won’t read a DVD -RW recorded in -VR mode.[/QUOTE]
Hello cholla[I hope I have pronounced your name correctly] [FONT=Wingdings]J[/FONT]
Many thanks for offering your time and help with my problem.
I had noticed the link etc re devcon, however, I searched my system and wrongly assumed that it was there, as I found it in C:Windows - System32.
However, none of the commands worked. Yet another dead-end I thought.
From your detailed assistance i.e. Collapse this image Expand this image Ifâ€¦â€¦â€¦.
through to â€¦â€¦â€¦…and then press ENTER, can I assume that your instructions are as per Vista. I can see no such method.
As I have XP, the command run is slightly different â€“ START-RUN-cmd â€“ OR START â€“PROGS-ACCESSORIES-COMMAND PROMPT.
Having read your post, I went back and dll the Devcon utility to the desktop.
As is my habit with all installs, I disconnected from the net. Disabled all security in real time, and ran the utility. I opened the zip file and noticed where the [B]3 files[/B] had been placed.
I then performed the command etc and got the same response as I had before â€“
â€˜devcon is not recognised as an internal or external command, operable programme or batch fileâ€™
So I had a look where it had been placed â€“ Docs & Settings/name/local settings/temp â€“ I found the folder, named ia64[not what I expected â€“ the 64 was a bit suspicious] Now, the unzip said three files â€“ this folder had only one, an application.
I was expecting to see an .exe there as well.
Then it struck me that the â€˜pathâ€™ was not right that is to a temp folder, so I moved the folder to system32, where I had first found it and thought I already had this utility.
I opened the moved folder to check and it still only contained the application file, with which I can do nothing â€“ when I right click to open it tells me that it isâ€™ not a valid WIN32 applicationâ€™.
I have searched the system for an .exe but nothing.
Perhaps the unzipper had not worked properly â€“ well it said three files. Tried it three more times and still the same. Then I noticed the folder title and realised I had dll the utility for a 64 SYSTEM AND NOT 32.
Q311272 clearly says that the dll Devcon.exe contains files for both 32 and 64???
Yet when I right click and open the icon on the desktop, the dll I am about to run is entitled â€˜devcon.exeâ€™.
Despite the disappointment from not being able to solve this problem, the help I have received from various forums and newsgroups has been tremendous, and I have performed many actions that I would never have considered doing. Yep even venturing into the registry. I still canâ€™t help thinking that the obsolete entries in there for other hardware fitted, cannot help. But as yet, nobody has suggested such a course of action.
Another anomaly, is the removal of the upper and lower filters â€“ a suggestion that has been put forward more than once. Mine are not there in any case â€“ they are not there for any of the other 4 or 5 DVDs that have been in my computer - my laptop has them entered, and so did the other computers to which I attached the current new DVD Drive, and in which it worked perfectly.
Liteon have been no help at all. The retailer has, which is most unexpected.
Thank you again â€“ I think the time has come to do a â€˜clean installâ€™ of the OS and if that does not work, then a new HDD.
Something is corrupted somewhere. <O:p></O:p>
Thank you again for your suggestion â€“ it was certainly worth a try, seeing that I had not done it right the first time.
