Re: dvdrw disappears

So much for that, the issue has returned....... again

Just wondering if it is safe to delete all of the UDF files,
there is about 15 of them
4 of these are in the NERO folder
the rest are in sytem32
although some of these are Wudf - not sure if they are the same thing.

As to changing the Ultra DMA Mode, as I have mentioned it appears to be
impossible through device manager.
I will have a look in the registry at some stage.

PS: Ulead Straight to disc SDK has not returned

thanks

Thankyou Michel !!

I dont appear to be able to change the DMA mode, although it can most
likely
be done through the registry
I uninstalled "Ulead Straight to disc SDK" and the problem seems to be
resolved
(3 restarts - all good)
not even sure how or why it was installed in the first place
After everything I have tried, I was starting to believe it was something
obvious, which is often the case.

Thankyou again - keep up the great work - very much appreciated

Hallo Shane,

Try putting your DVD writer in Ultra DMA mode 2 and remove UDF reader as
well since that is used to formatwre-writable cd's and Xp handles that
well
by its self.

thankyou for both of your prompt replies

I should have also mentioned that I have a CDRW connected on the same
IDE
controller that works fine.

Peter,
I have not had roxio installed since installing XP late last year
and I have reformatted twice since then
I am currently using Nero for burning and have not had any issues until
recently

Michel,
My problem is intermittent, the device is available at the moment
As I belatedly noted at the top of this post, I have a CDRW working
correctly all of the time, I believe this may make your initial
suggestion
unlikely in my case ?

with your second suggestion
both optical devices are connected to the
Secondary IDE Channel
Device 0 (CDRW) has a current transfer of Ultra DMA mode 2
Device 1 (DVDRW - Problem device) has a current transfer of Ultra DMA
mode
4
I was initially hoping to peg this back to Ultra DMA mode 3 to attempt
to
rectify the issue, but, the only adjustment available is changing the
Transfer mode back to PIO
is this what you are suggesting ?

Thankyou
Shane

Hi there,

This happens quite often if one of the third-party packages has been
uninstalled. They add references in the Registry for modules which
they
use,
and these references fail to be removed, leaving Windows unable to
find
the
files apparently needed for CD devices at the next boot. There is a
simple
Registry patch to correct this (download it
aumha.org/downloads/cdgone.zip.

Before using the patch, be sure to back up the Registry. After using
the
patch and rebooting, the drives should reappear. Any third party
package
that is still required will then need to be re-installed.

This problem also may arise if there is underlying trouble with the
Input-Output system of the machine: for example, interactions with
controllers like Promise or Highpoint, or with special drivers. It may
be
worth trying a change in the DMA settings for the device in Control
Panel
|
System | Hardware | Device Manager. Under IDE controllers, double
click
on
the Primary or Secondary IDE Channel concerned, then click the tab for
the
Advanced Settings page.



Best Regards,

Michel Denie

This problem may occur if some CD recording programs from Roxio Easy
CD
Creator is installed on the computer, and if the version of the CD
recording
program is not compatible with Windows XP.

Hi
Hoping someone has some info on this issue.

A couple of weeks ago my DVDRW (liteon SHM 165P65) started
intermittently
disappearing from my system
ie: does not even show up in device manager.

I tried to read an old backup disc
which was formatted using Adaptec DirectCD
this installed udfreader on my system
have had the problem ever since

I have tried
waiting for it to be working - uninstalling it through device
manager
and
letting it auto reinstal.

sfc /scannow

reinstalling windows

reformatting my hard drive

After reformatting it worked fine for a while
but, after installing all updates through 'microsoft updates' the
issue
has
returned

Does anybody know if this is a known issue with a particular update
?
and if so if there is a fix.

I receive no error codes at all

there is no upperfilter or lowerfilter values listed under the
registry
key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Any help/suggestions will be appreciated
I have noted other people out there with very similar current
issues,
but,
nothing identical so far.

Thankyou
Shane
