Hello everyone!
I have a Vaio PC.It came with Preinstalled DVD-Burner Pioneer A04.And a CD-Rom Drive. Suddenly I checked today The DVD-Burner & the cd-rom drive doesen't show up. I didn't do anything, but it disappeared automatically.All I did was Password Protect my Windows XP (user Accounts). Should I run the forceaspi. I don't get any ASPI Errors. The Drives don't just show up. I restarted a couple pf times.Same Problem.
Thanks In Advance! :)

Note: Im running Windows XP (home edition) -preinstalled.

Well, this has happened to me in Win2k, so I imagine the same rules could apply. Here's what I found on a technote:

To make the CD ROM's reappear you will need to edit your registry.
Before doing this I highly recommend that you make a back up of your
Registry. This is very important in the event you delete the wrong key. Hold on tight, here we go.

After running Regedit you will want to find the following Registry Keys and delete the following entries:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

(Delete only the keys below)

UpperFilters
LowerFilters

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

(Delete only the keys below)

UpperFilters
LowerFilters

(You must reboot for changes to take effect)

Thanks very much for your fast reply!!! :)
How can I get to the registery?

[padre]

Start, Run "regedit.exe"

Be careful, and make sure you backup the registry before making any changes.

Thanks Again bro!!!
But in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Only the lower filters file shows up.And it does Not have any upper filters.
Thanks Again!!! :)

If there is only the lower filters, delete them and reboot. See if you drives come back. As I recall on mine, I only had lowers too.

You can also apply www.aumha.org/downloads/cdgone.zip

It gives you the regedit commands in a .reg file (you just click on the .reg file and it executes).

I appreciate the help! :)

Thanks in Advance!

So the drives are now being seen in the My Computer and File Manager, but not by DVDit and RecordNow? If so, I don't know what to tell you. Sorry.
