Optical drives dissapear after system sleeps

[Eddie G]

I did a search on this issue and found a mention of it on the Windows
Support site which mentions a hot fix, which I did by calling MS and
haveing them email me a file to install on my system. I also did the
registry tweak also mentioned on the MS support site. Neither of
these "fixes" work. After a reboot my optical drives are recognized
by the OS and work fine...it's just after the system sleeps that the
are not in "my computer" or my "device manager".

Please help if you can!!

Thanks!

Eddie,

I wonder whether this KB article could apply to your situation:

I don't know whether it applies or not, but it could at least be a clue as
to the problem, hopefully.

This KB is how I knew of the hotfix and the registry tweak. This did
not help.

Eddie,

Ah, so we are talking about the same KB article. This is referred to as a
failure in communication.

Anyway, I've only one other thing for you to try: I don't know whether
you've seen and tried this step, but some folks have had good fortune in
resolving problems similar to that which you have by deleting the INFCACHE.1
file. It's located at C:\Windows\inf (scroll down to the file). It's OK to
delete the file even when it has nothing to do with the problem. This
procedure doesn't work for everybody, but you won't know until you try it.

Freddy,

I did as you suggested and this morning my system shows the optical drives
after it was sleeping. I hope this is a permanent fix and I just didn't get
lucky.

Thanks!!

Eddie,

Great! I hope it stays fixed, too. Deleting that cache file has done
wonders for quite a few folks.

 

[Eddie G]

It didn't stay fixed. My system went to sleep after I posted, and now my
optical drives are gone.

<sigh>

That's a bummer. I'm out of ideas. Your guess is as good as mine. More
research on the Internet? I wonder why the previous trick worked for a
while? What's the message here? I give up.

Hello,

I am having a similar problem, but it is recent. I have had Vista Home
Premium installed for a couple of months. Just in the past week I have had
a problem where occasionally after I shut down and start my computer my
CD-ROM is not identified. I have tried resetting the BIOS. What does work
is going back to a restore point, but this is more of a pain than it is
worth.

I tried to delete the file mentioned above, but I am having a problem with
the permissions. I am wondering if one of the recent updates had anything
to do with it?

Any additional thoughts would be great!

 

[Eddie G]

To delete the file you need to right click on it and select
Properties/security and find your user name and allow it to access the file.

If I understand this thread correctly, your problem was fixed for a
short time by deleting INFCACHE.1, is this correct?

I'm wondering if Vista re-created that file after you deleted it?

Don,

Yes, Vista likely recreates the file after you delete it, but the idea is
that it recreates it without the former erroneous contents which is what was
causing the problem originally. That brings up an idea: Rather than
deleting the file, try renaming it (from .1 to .2) on the premise that when
Vista recreates the file the prior erroneous contents won't get picked up
again. This renaming approach is based on the premise that the old erroneous
contents are also recreated. Just an idea to try.

 

[Eddie G]

My system did not recreate that file yet.

Keep trying.

Eddie,

Do you have a burner program installed, like Roxio or Nero? Some people
have had strange issues with their CD/DVD-ROM drives when either of those
two programs are installed. In those instances, uninstalling those burner
programs resolved the problems. Some versions of those burner programs have
compatibility issues with Vista, and thus have caused problems.

If you do have one of those installed, consider uninstalling it to see what
happens. You can always reinstall it if nothing good comes of it. If you
find that uninstalling the program resolves the problem, then I can recommend
some burner programs that work well with Vista. Something else to think
about.

Eddie,

When you stated, in your initial post, that you did the registry tweak, were
you referring to the tweak in this article?

http://support.microsoft.com/default.aspx?scid=kb;EN-US;320553

If not, try the tweak suggested in that Microsoft publication. If you've
already done that, ignore this post.

Freddy,

I did NOT try the registry tweak on this link you sent me, just the
one on the original KB article at the beginning of this thread. I saw
the article you are referring to me now but ignored it as it refers to
Vista Beta, and it also does NOT mention the optical drives working
but failing after the system comes out of sleep mode, which is what I
am experiencing. When I reboot my machine my optical drives work fine
until my system goes to sleep.

 

[Bob]

I tried that fix and it did not work. I was able to use the restore to go
to an earlier point and the CD-ROM was there, however, that stopped working.

I have tried restoring my machine and uninstalling the device again, no
success.

I am a minute away from going back to XP. I love Vista, but this problem is
driving me nuts!!

Eddie,

I don't think it matters that the KB refers to a Beta version, since it
could also apply to other versions. At the time it was written, other
versions may not have been released.

It's up to you, but you could try the tweak just to see what happens. I
don't think you will get any adverse results by doing it. You may not even
have those entries in your registry to remove, so in that case it doesn't
matter. Even if you don't want to do it, take a look at the KB article and
then at your registry to see whether the KB would even apply. I wouldn't
reject anything out of hand.

All,

Let's start over on the left so that out names don't disappear on the right.
Here is another point to consider, before anyone gives up and reinstalls XP
or smashes their computer with a hammer: Are these drives compatible with
Vista? What if they don't appear on the Vista compatibility list? Should
you all check out this point? Up to you.

Also, would a replacement drive perform any better? New drives are
inexpensive these days. It doesn't cost much to just replace the drive to
see what happens. And if that doesn't work, you haven't lost much, except
for inconvenience. Something more to think about and to consider.
