MOVED FROM XP SUPPORT SECTION


hi, my son has a problem with his pc.

The dvd-rw has vanished from windows.
This problem started after Daemon tools was installed. He took the machine back to where he bought it and they removed daemon tools and reinstalled some drivers for the drive, it worked again, and they said he could reinstall daemon again.
He reinstalled daemon, and of course the drive promptly vanished again. It still shows in bios.

He is running windows xp home, the drive is a sata dvd-rw drive.


I see from some similar threads here, and elsewhere, that this is a known issue and that I should try to remove filters using these instructions:--

Step 1: Start Registry Editor
Click Start, click Run, type regedit, and then click OK. Registry Editor starts.
Step 2: Delete the UpperFilters registry entry
1. In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
2. Expand SYSTEM, and then expand CurrentControlSet.
3. Expand Control, and then expand Class.
4. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
5. In the right pane (topic area), click UpperFilters.

Note An UpperFilters.bak registry entry may also appear. To delete the UpperFilters registry entry, you must click UpperFilters and not UpperFilters.bak.
6. On the Edit menu, click Delete.
7. When you receive the following message, click Yes to confirm the deletion of the UpperFilters registry entry:
Are you sure you want to delete this value?
The UpperFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.

Note Do not exit Registry Editor. You must have this program for the next step.
Step 3: Delete the LowerFilters registry entry
1. In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
2. Expand SYSTEM, and then expand CurrentControlSet.
3. Expand Control, and then expand Class.
4. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
5. In the right pane (topic area), click LowerFilters.

Note An LowerFilters.bak registry entry may also appear. To delete the LowerFilters registry entry, you must click LowerFilters and not LowerFilters.bak.
6. On the Edit menu, click Delete.
7. When you receive the following message, click Yes to confirm the deletion of the LowerFilters registry entry:
Are you sure you want to delete this value?
The LowerFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.
8. Exit Registry Editor.

however, when I go to Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}, I do not see anything saying Upper or Lower filters.

Help please :(

noone? :(

if the drive is listed in the device manager right click on it's listing and choose uninstall
reboot and check if it is working
in the registry under local machine/software
check if daemom tools are still listed

katchin

drive is not listed in device manager, it is listed in bios though.

dai

try the filters again from this the one you posted above is for xp although 99.9% the same
vista has extra places to check

the pc with the problem is an xp machine

katchin

so i'm missing drivers for the dvd? i presume something happened to the generic drivers in windows, how can i replace them?

dai

uninstall the drive from the device manager and reboot and windows will reinstall

katchin

problem is it isnt listed in device manager. I may just put xp pro on that pc and an older version of daemons tools, maybe that will sort it. shame though.

dai

daemons tools could be the problem uninstall it

katchin

SOLVED. I removed the dvd drive and tried it in another machine, worked with no problems. This was after the drive had reappeared a couple of times and vanished again in the first pc.

I replaced the sata cable with a new one and hey presto, all ok.

dai

glad you have it sorted
