gtitus,
First off, very useful tweak. It has saved me some troubleshooting time already. I am curious however about what put you onto this solution? If you have the time, can you explain a bit?
Thank you,
Luc...
i had the same problem , and after many hectic hours found that the dvd and cd drives wer worn out .they would not close all the way , but looked like they did close, after i disasembled them both and cleanded off , smothed out ,the worn rails that the disks holder rides on , they have worked for ober a year .
Gary, if the problem remains after you have gone back to a known good previous state (restore point) then it certainly sounds hardware related to me.
The fact that both drives are not recognized suggests it is not an individual drive problem. I can immediately think of two potential problem sources - one minor and one major. The minor one is a bad cable (assuming you are using an IDE cable) and you can confirm whether that is the problem by replacing the cable. An IDE cable is cheap and try to get an 80-pin cable and not the 40-pin one although it would also work. Of course if you have SATA drives then the probability of this being the problem source is significantly diminished since you'd have two SATA cables for the drives, and it is unlikely that both cables are bad. The major problem source is of course the motherboard itself. Either the IDE connector on the MB is bad, or the Southbridge is bad. Either way your MB is kaput.
My HP notebook computer had exactly the same problem. After doing everything I could think of without success I called HP tech service. They explained that they had a motherboard issue and asked that I return the unit for a motherboard replacement at no charge. When I did that, I had the same unit back working as new within 5 days.
I had the same problem with a laptop.There was nothing wrong with the CD Rom the problem was in the xp registry.Somehow a file got lost.Not knowing much about the registry I took it to a computer shop and they found the file that was lost and now its working great.
First disconnect both drives. Then try booting with one drive connected, then do the same with the other. If niether one is recognized check your BIOS and make sure they are enabled. If this doesn't solve the problem then try a new ribbon cable.
Hi there
I have come accross this problem a few times before and in my experience a simple bios reset usually cures it
remove the power from pc after shutdown and remove case /side look at the motherboard and locate the battery or refer to MB manual some boards have a jumper reset otherwise remove the battery and press the start switch a few times replace battery and close case before powering up try restarting you should see a F1/F2 option after post screen (power on self test ) reset bios to how you like it and boot up remember to reset date and time hope this helps you
regards Tim
I know my answer is not very high tech, but the same thing happened to me a few months ago, and I tried everything to get my computer to recognize the DVD-rom, but to no avail. Finally, I just called the manufacturer, and within 10 minutes, we did some work in the Registry, and all was fine. Sorry I don't have a better answer, but it worked for me.
Greetings,
My question would be did you remove any multimedia siftware last week just before you noticed the optical drives were no longer being recognized (i.e. Roxio, Nero, etc...). Removing these software packages can also remove the drivers that allow the operating system to recognize and utilize the drives. I would recommend that you try reinstalling a copy of Roxio and see if your drives come back.
Best Regards,
Hunter
I would check my BIO system.. Start you computer and push F2 to enter
BIO menue to check...
I had the same problem with Vista,I download I-Tunes DVD ,E,F they all went out of the window,So I deleted I_Tunes and all came back.Contact Apple no help.

Too many updates beyond the orginal programing of the system!
It's like learning all the laungages of the world but your only
going to speak english!
I formated my computer to the orginal factory programs.
downloaded only what I needed. 90% of the updates I downloaded
weren't necessary! My computer runs great and CD and DVDs play great

Computer Model: Sony PCVRX-991
System: Microsoft Windows XP Professional Version 2002 Service Pack 3
Computer: Intel(R) Pentium(R) 4
CPU: 3.06 GHz
1.00 GB RAM
System Restore is turned off on all drives.
Device Manager:
DVD/CD-ROM drives:
MATSHITA DVD-ROM SR-8588
SONY DVD RW AW-Q170A
Device Manager shows nothing is wrong with either DVD drive.
(meaning there is no yellow question mark next to either entry)
My Computer Folder:
DVD-RW Drive (F:) = SONY DVD RW AW-Q170A
DVD Drive (G:) = MATSHITA DVD-ROM SR-8588
Okay those are the specs/folder "views".
Now the problem:
My computer does not allow me to open the G: drive but the link to each drive is visible in the "My Computer" window.
When I put any media (DVD or CD or Data Disc)
into the Matshita DVD-ROM Drive (G:)
Nothing happens.
So I double click the DVD Drive (G:) icon
An "Insert disk" window appears stating, "Please insert a disk into drive G:." along with a "Cancel" button.
Then I Hit Cancel
I open the drive to see that there is indeed a disk in it.
I close the drive.
The drive light flickers for awhile, then stops (perfectly normal)
Then I try to trick the computer into showing me the contents of the CD I just verified is in the G: drive.
I RIGHT Click the DVD Drive (G:) icon and select "Explore"
An "Insert disk" window appears stating, "Please insert a disk into drive G:." along with a "Cancel" button.
I click the Cancel button.
I RIGHT Click the DVD Drive (G:) icon and select "Eject"
the drive slides open.
I take the CD out of the G: drive
I put it into the OTHER drive.
(DVD-RW Drive (F:)
I close the drive.
The drive light flickers for awhile, then stops (perfectly normal)
And Immediately Windows "My Computer" recognizes the Media as an "Audio CD" (F:)
Therefore it's not the Media I'm using.
Drive F: (The Sony DVD-RW) works
Drive G: (The Matshita DVD-ROM) doesn't work
Which brings up another strange thing.
These drives USED to be called Drive G: and Drive H: (respecively)
I'm not sure that's related to the problem, but I thought it was worth mentioning.
I am really at a loss.... most of the advise offered so far seems to my untrained eye to be related to people who have yellow question marks next to their DVD drives in Device Manager (I DON'T have that problem)
I can duplicate my problem with any media type
(DVDs, CDs, Data Discs)
In each instance, Drive G: tells me to
"Please insert a disk into drive G:."
while Drive F: allows me to open the folder and see the files.
I haven't installed any new software recently.
EXCEPT for the weekly Windows XP "Automatic" updates.
and honestly, I don't know when the problem started,
I just know that I first noticed it about 2 weeks ago -- just like Lee Koo.
We both have SONY's could it be a Windows Update that created the problem?
Please help.
Windows updates in combination with other programs can cause problems!
Like taking different combination of pills causes different side effects!
Try to restore back before you added the updates and see what happens!
