Hello All...
I am a CSE for Beaming DATA Corp. We bought some HP
Pavilion dv2000 laptops. There has been some problems with
the dvd drive in them.
the DVD drive is called
slimtype DVD A DS8AZH ATA
A really good drive on an XP machine. It seems there may be an
exploit somewhere in the HP updater. When we update the
driver the drive dies.
Here is the fix:
Run your update or whatever changes you need to make to your
system. Go to the device manager in the control panel and
disable the DVD drive.
You will have to work in the registry because someone is
deliberatly changing the registry and this causes the drive to quit
working.
=== Backing Up Registry and Registry Key ===
CAUTION: The registry contains critical information and a
registry backup is essential. An incorrect registry
entry may cause serious system problems or prevent the
computer from starting. You will not be warned of any
incorrect registry entries. If the registry is not
backed up, the only way to recover the system is to
reinstall the operating system. Do not double-click the
Backup.reg file on the desktop unless you intend to undo
the changes you are making to the registry.
1. Click Start and type regedit in the text box.
2. Click "File" in the menu.
3. Click "Export" from the drop-down menu.
4. Click the down arrow beside "Save In" and select Local Disk
(C.
5. Type Backup.reg in the File Name field.
6. Click Save.
=== Deleting UpperFilter and LowerFilter Registry Keys ===
1. Click Start and click Run.
2. In the Open box, type regedit and click OK.
3. Click the plus (+) sign beside HKEY_LOCAL_MACHINE.
4. Click the plus (+) sign beside System.
5. Click the plus (+) sign beside Current Control Set.
6. Click the plus (+) sign beside Control.
7. Click the plus (+) sign beside Class.
8. Locate the {4d36e965-e325-11ce-bfc1-08002be10318} key
and click it.
9. On the File menu, click Export.
10. In the File name box, type savedkey and click Save. It is
better
to save the "savedkey" to the desktop.
11. Click the REG_MULTI_SZ data type UpperFilters (found in
right
window pane) and then click Delete on the Edit menu.
12. When you are prompted to confirm the deletion, click Yes.
NOTE: If this data type is missing, continue to the next
method.
13. Click the REG_MULTI_SZ data type LowerFilters (found in
right
window pane) and click Delete on the Edit menu.
14. When you are prompted to confirm the deletion, click Yes.
15. Quit the Registry Editor and restart the computer.
The CD-ROM drive, DVD-ROM drive, or CD-ROM R/W drive
should now appear
in the My Computer window.
CD/DVD drivers reinstall:
1. Select Computer and click on Manage.
This will prompt you with a User Account Control Window.
2. Click on Continue.
This will open Device Manager.
3. Click the "+" sign next to CD/DVD Drive.
4. Click the first device listed under CD/DVD drive to highlight it.
5. Click uninstall to remove the CD/DVD device driver.
6. Click OK for confirmation.
Restart the computer by powering it completely OFF.
This is very important because the laptops will hibernate or not
load the corrections in the registry until the machine is powered
down.
This fix will workwith Any modle that has the drive compaque HP
whatever.
It is a good idea to make a restore point now that you have the
drive working. The machine can be restored if the dive goes
down again.
