Since Windows 2000 is fairly close to XP, I thought I would ask...I

believe my Upper and Lower Filters values in the key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro  l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

is corrupted because my CD-ROM is recognized by the system but cannot

play any CDs or show any data. By the way, the values read:

Upper Filters: REG_SZ  InCDPass GEARAspiWDM Cdralw2k pwd_2k

There is also a .bak value: InCDPass GEARAspiWDM



The Lower Filter is: PXHelp20 PFC Cdr4_xp

There is also a .bak value of PXHelp20 PFC



I'm a little leery of deleting these keys (as advised) but can someone

tell me how relatively safe or not these particular values are and

what danger exists in hosing the registry? I do have a backup.



Thanks for any help.

You want to be careful deleting some of these CD writer keys, it could

render your system unbootable.  Read here for possible solutions:



http://search.microsoft.com/search/r...8002BE10318%7d



The reason you can't read your cd's might be because an associated Nero

service doesn't start.  Look in the Services Manager to change or start

the necessary service(s).



A note about InCD:



"This is the InCD software which enables you to drag files onto a CD-R

directly from Windows Explorer, or to save onto CD directly from within

applications like Microsoft Word, without using the CD Recording

software that came with your CD-Writer (Nero).  While a great and

potentially very useful concept, the limitations of InCD CDs (CDs

created with InCD are only ever guaranteed to be readable in CD Writers

that are the same model as the CD Writer in which the CD was created –

it is not unusual not to be able to read a CD created via InCD, in

another CD-ROM drive) lead us to always recommend its removal.  We

advocate to instead always use its sister product, Nero (also called

"Nero Burning ROM"), to create CDs, as that is the only method that

guarantees that you will be able to read the CDs you create in any other

CD, CD-Writer, or DVD drive – a crucial consideration if you are using

CDs for data backups !



Recommendation :

Unless you do make use of InCD, remove it via "Add/Remove Programs" in

the Control Panel.  Otherwise right-click on it in the System Tray and

temporarily disable it whenever you need to use other software that will

want to write to your CD Writer."

These CD/DVD writer software packages can cause havoc on your system.

As for InCD I would follow the advice offered by answersthatwork.

Gosh, thanks for this advice. I really was queasy last night attempting

this for fear I'd hose the system.



I'll check out the Services Manager and delete the damned thing.

PXHelp20 is a faulty driver. You may want to try deleting it first.

Hi Neal - Try using this reg file to handle the delete (it takes care of

deleting some other things which can cause problems as well):

http://forum.aumha.org/ http://www.aumha.org/downloads/cdgone.zip  This is

pretty much the "standard" fix for this type of issue.  Backup first so that

you can recover if there are problems (there aren't usually, BTW).

Jim, do I replace the CD-ROM default Microsoft Driver? One poster said

I might have a corrupted driver. I do have a fresh copy of

CDr4_xp.sys. Before reboot after when system searches for driver for

CD-ROM?



Thanks!

Hi Neal - If you're sure that you have a "clean" copy of the driver, I would

replace it first, then reboot and see if that fixes the problem.  If not,

you can then run the .reg fix.  You may have difficulty replacing it because

it's an "in use" system file; if so, you can use one of the programs below

to do that for you.



I don't currently happen to have a copy of XP installed, but I believe that

that's not a protected file (my version - cdr4_2k.sys - doesn't appear to be

in my current Win2kProSP4), so you should only have to replace it in

%SystemRoot%\System32\Drivers folder I think, but check the

System32\dllcache folder and the ServicePackFiles folders also just to be

sure, and if it's there replace it in those locations also.



From one of my "standard" cleaning-up-malware posts:



"A program called Copylock, here,

http://noeld.com/programs.asp?cat=misc#CopyLock can aid in the process of

"replacing, moving, renaming or deleting one or many files which are

currently in use (e.g. system files like comctl32.dll, or virus/trojan

files.)"  Another is Killbox, here:

http://www.downloads.subratam.org/KillBox.zip

A third which is a bit different but often useful is Delete Invalid File,

here:  http://www.purgeie.com/delinv.htm which handles invalid/UNC

file/folder name deleting, rather than the in use problem."

Thanks, Jim. Just one last item before I take your advice! For Driver

Details on my non-functioning CD-ROM, I see a series of driver files

in Device Manager/Driver File Details:



They are all in c:\WINDOWS\system32\drivers folder:

Cdr4_xp.sys

Cdralw2k.sys

cdrom.sys

GEARAspiWDM.sys

imapi.sys

InCDPass.sys

pfc.sys

pwd_2k.sys

PxHelp20.sys

redbook.sys

storprop.sys



There are green checks next to the redbook, storprop, imapi and

cdrom.sys files.So is the cdrom.sys the magic file here if I can get

that one? Also PxHelp20.sys may be fault; I did get a new version of

that one.



I did not see a dllcache folder but the cdrom.sys file is in my

Service Pack/i386 folder.



Is the easiest thing just to run the .reg file?

BTW, the InCD file is something that Nero Burning ROM must have

installed...grrr. Cdralw2k is from Adaptec which makes Easy CD Creator

7, the burn program I have,



Thanks for all your help.

Hi Neal - Ah, new data!



If you have both InCD and Easy CD Creator's Drag to Disk DirectCD, their

respective drivers are known to confict badly with each other.  These are

two fundamentally different approaches to packet writing to your RW CD/DVD.

You should try to uninstall one or the other (I would suggest the InCD, as

IIRC it's easiest - use Add/Remove Programs in the Control Panel).



You might also want to disable XP's built-in CDWriter if you consistently

use Easy CD Creator or Nero by preference.  There have been some reports of

conflicts here also.  To stop it, go to Administrative Tools|Services.  In

Services, double click on (IIRC I think it's)    Imapi cd burning     then

Stop and then Disable.



Reboot after each removal/disable, then run the .reg file fix and reboot.  I

would suggest that you try this first before replacing the driver, contrary

to what we last discussed.
