Book: CD/DVD device is not accessible. Access denied message

• Drive external drive is not accessible, access denied.

  My computer (Win7 Home Prem) ran chkdsk after an update of windows, probably triggered by ccleaner or glary utilities. My external hard drive was plugged during the update, reboot and chkdsk. The chkdsk command probably checked my coz external HD, I can see folders/paths that were there. The next day I couldn't access my HD due to a mistake, saying: it was not accessible and access is denied. I searched online potential solution and tried the following without success, and they have been applied using an admin account and an admin cmd.

  * Change the permissions and ownership, but the property always says it's impossible to determine the owner.

  * Changed the share permissions.

  * Do you have 'takeown' and a 'icalcs' has changed owner but same error.

  * Check the disk management, drive seemed ok with the letter drive and all.

  * Ran chkdsk /F on both of my C: drive and external hard drive, both completed successfully without error during the analysis and not found bad sectors.

  * Program of Unlocker used to check if player was running another process, found nothing.

  In my computer, it shows the letter drive and NTFS, but not bar showing free space. Properties would show 0 free space / used. Here I can go to cmd and access the content from there. I used the function of 'Explore disk' of glary Utilities and I could see the content and even run mp4/avi files in the player. So I guess the drive and its contents is ok, just that I can't access it through normal means.

  Thanks in advance!

  Hi LeBlanc,

  I apologize for the late response and can certainly understand your concern. I appreciate your efforts. As you mentioned that you are not able to access the external drive, and you receive the error of access denied when you connect to your user account, I suggest to try to create a new administrator user account and then try to access the external drive.

  To create a new user account, please follow the steps mentioned in the link below:

  Ask them of the exact key sequence

  Hello

  Have you tried to update the CD/DVD drive?
  You could go to the Device Manager and could remove the reader of CD/DVD from the list of devices.
  Then, you must restart the laptop.
  After restarting again the Windows operating system will recognize the new device as the CD/DVD drive and will initialize and reinstall the driver.

  Then try using the new CD/DVD drive

  Hello Urbchguy,

  Thank you for your message.  It is possible that the profile has been corrupted.  Let's try the following:
  Connect to your computer with one of the admin accounts that works properly.
  Click 'Start' > click 'My computer' > navigate to the following folder:
  C:\Documents and Settings
  Rename the problematic profile to add _old after profile.
  example: C:\Documents and Settings\jsmith_old
  And then disconnect and reconnect under the problematic connection.  A new profile will be done, you can then copy the 'old' profile data to the new.
  Please let us know if it did or did not help to solve the problem.

  Hello

  I give my 15 years old nephew an old laptop so I am trying to run a system recovery and restore it to its original state factory.

  As soon as I clicked on Recovery Manager > System Recovery > restore to their original factory condition, I get a screen with this message Windows Boot Manager:

  Windows could not start. A recent hardware or software change might be the cause. To solve the problem:

  1. Insert your windows installation disc and restart your computer. (don't have)

  2. choose your language settings, and then click "next".

  If you do not have this disc contact the Adminitrator's manufacturer or a computer in your system.

  Status: Oxc0000225

  Is there a way to get around this. I would get to it as soon as possible, but I want to wipe all my info beforehand.

  Thank you!

  try to perform the recovery by using the partition.  boot f11 and recovery manager must take over. If not, or if the process does not finish successfully, perform a large hard drive. If the test successfully you will need to order a copy of your HP recovery disk.

  as an alternative, you can create a new admin account and simply delete your existing account after.

  hope this helps

• Attempt to start in the recovery environment gives 0xc000000e error - "device is not accessible.

  HP Pavilion g4-1117dx laptop computer 4 GB, Win 7 Home Premium SP1 64-bit running

  Tried to boot into the recovery environment through the HP Recovery Manager (v 2.0.9.0 Rebecca.exe 3/25/12)

  However, I get to the Windows Boot Manager screen that says error 0xc000000e - device is not accessible

  I scanned the partition HP_TOOLS for errors, including an analysis of the sector, but it does detect any errors.

  FYI - I have repair disks that I created.  Is it possible to repair or recover only the partition HP_TOOLS?

  Just to be clear, the problem is with my Recovery partion only.  Win 7 in main boot works fine.

  Suggestions to fix or repair, please?

  Don't know what else to suggest other than using recovery discs to reinstall. If you have recovery disks, the recovery partition is not really necessary, more a convenience than using disks, that's all.

• IPad & Ipod Nao do not installed the drivers. Get the access denied message.

  IPad & Ipod Nao do not installed the drivers. Tried to update the drivers and got the access denied message. With the Ipod Nano "Type - hand-held device" get message "this device does not work properly because Windows cannot load the drivers required for this device. (Code 31) on location IUMBus enumerator.

  Hi Mos,

  Thank you for your update on the issue.

  Basically, UMBus enumerator or enumerator of Bus Mode user enumerates devices on different buses to user mode. Umbus.sys is the universal management Bus Enumerator driver and a 32-bit executable that requires no direct user interface. You may need to check if there is a yellow exclamation on this device driver in Device Manager and update driver if required. Refer to the following steps to do:

  1. Open Device Manager by clicking the Start button, click Control Panel, click System and Security, and then, under System, click the Managerof peripheral . If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. Click view in the menu, and then select Show hidden devices.
  3. In the list of hardware categories, find and expand the System devices and select the UMBus enumerator(with a yellow exclamation point) and then double-click the device name.
  4. Click the driver tab, click Update driver, and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

• "Access denied" message in Device Manager

  I can't update the driver software in all my gear installed on my computer via a right click on it in Device Manager. It happens to the progress bar 'Software Installation pilot' before stopping and give me a message "access denied." Why would he do that? I'm the only one who touch my computer, it uses a lot less.

  In addition, how can I bypass the "Access denied" message and give me permission to do stuff like that?

  Hello

  Thanks for posting your question in the Microsoft Community!

  I see from the description of your post, that you are getting the error message access denied when updating driver software.
