No access to CD/DVD disc - list only

Hello,

The DVD writer in my Dell laptop (M4400) will read the discs and list the files correctly in Windows Explorer, but allows no access to the files. I get an "Access is Denied." error message when trying to copy files from the dvd (or cd) disc to my local drive. Trying to double-click files on the DVD disc, or right-clicking a file results in no action and no error message displayed. So it is unusable for anything other than getting a list of the files and folders on the disc.

This is a Windows XP sp3 system and the dvd drive is identified (in Device Manager) as TSSTcorp DVD+-RW TS-U633F. This behavior occurs for any user on the machine regardless of whether the user has local admin privileges or not. Same problem either way. It also occurs on discs I have written (using that writer, previously) or commercial discs.

I believe this is not a problem with the hardware, but rather is a problem with some system or registry setting or files or missing files. And here is why I believe that:

I have installed WMWare Workstation version 7.0.1 and have created a couple of virtual workstations - one is Windows 7 and the other is Windows XP SP3. When I launch either one of those workstations and try accessing the DVD disc, it works just fine! Files on the disc are accessible and can be run or viewed or copied. So that seems to indicate it is not an issue with the hardware at all.

I have McAfee anti virus software installed and up-to-date. Additionally, I regularly check the running processes for anything that seems unusual so I don't think there is anything running that is causing this.

Does anyone have an idea of what might be causing this access issue?

Thank you.

Had this trouble before, I solved it by editing the registery
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
The value Data for String Values allocatecdroms and allocatefloppies, must
be 0 not 1.

I would try to create a new user and profile and see if that works.
Your normal user profile may be corrupted.

I hope this helps !

SysExpert -

I logged on with two other (established) user profiles and the problem stilll exists. I then tried creating a completely new user profile, also with the same results. Still no access to the files on the DVD disc. No right-click menu, no drag and drop ability and no double-click (launch) ability. Yet I can do all those functions if I access this drive and disc through a VM session. Doesn't make sense to me.

This really has me stumped.

Thanks for your comments.

bad registry entry, malware , or driver.

try removing the device from the hardware device - uninstall the driver and reboot.

Also check the upper and lower filters in the registry


From: shekerra    Date: 08/12/2001 05:38PM PST
               See if you have this key in your registry for 'upperfilters' and 'lowerfilters'

               HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
               {4D36E965-E325-11CE-BFC1-08002BE10318)
               If so export it to a backup directory and then delete the two filter keys listed above.  Then go to
               device manager and remove the exclamation marks and reboot.
Missing Drive missing CD
Delete upper and lower filters?

More information on this problem:

I said previously there is no context menu for a right-click on any files on the DVD disc, and double-clicking the files will not execute the files. Dragging and dropping the files from the DVD disc to a location on the hard drive also does not work, but it does display an error after I attempt to drop the file onto the desktop (for instance). Here is the error message text:

Title: Error Copying File or Folder

Message text:
  Cannot copy <filename>: Access is Denied

  Make sure the disk is not full or write-protected
  and that the file is not currently in use.

I can verify the file is not in use at the time, nor is the destination is not full or write-protected. This message is displayed everytime I attempt to drag a file from the DVD disc and drop it onto a location that the user has write access to.

Thanks

Update:

SysExpert - I uninstalled the DVD drive and rebooted. I also removed the upper and lower filters in the registry. The problem still exists after the reboot. I visited the KB article in your last post. Tried running the MATS tool, but it would not run on my system for some reason - encountered a runtime error immediately.

So the problem has not been solved. Thanks for all your suggestions.

I would try something like ccleaner to see if it can help . Not sure if this is a bad driver, registry or permissions issue.

I hate to say it, but a wiper and reinstall is sometimes the only cure for some types of problems.

oops
wipe  not wiper.

SysExpert - I understand that wiping and reconfiguring the machine will most likely solve the issue I am having with the DVD disc access. SInce it does work fine in some situations, I was hoping I could discover what setting or file was causing the issue and avoid the tedious and time-consuming business of reinstalling the OS and all my software. I have done that too many times - not a lot of fun.

I appreciate everyone's help on this issue. I am now going to accept a wipe and reinstall is the only solution I have left.

This solution basically says there is no solution other than the brute force method of wiping and reconfiguring/reinstalling the OS and all software. It does not really solve the specific issue, although it should help me get past that problem.
