"C:\ is not accessible. Access is denied"error message

original title: TEARING OUT MY HAIR - I'm a fool.

I was playing with advanced sharing and privileges and now I can't access to my c drive.  I feel like a fool.  I don't know what I deleted, but it does not restore my access.  He said "C:\ is not accessible.  Access is denied... " I right click on the c drive and try to change the privileges.  For example, to provide access to everyone, users, guests, etc. - and the message I get is "an error has occurred while trying to change the admin part.  Access is denied"- HELP.  I'm so frustrated.

In volume NTFS, only the owner of an object (file, folder,...) which can change permissions for this object. You must take possession of your C: drive somehow, after this only that you can grant permissions to users.

Try to get into safe mode, log in as 'Administrator' (enable that account first if it is currently disabled). Then right click C:\ drive, click Properties. Go to the Security tab, and then click Advanced. Go to the owner tab, and then change the property to 'Administrator' first. Then, grant permissions like these for these users [CMIIW]:

Authenticated users: read, execute, write, edit,
Administrators: Full control
TrustedInstaller: Full control
SYSTEM: Full control
Users: Read, execute

Finally, change the owner once more to "TrustedInstaller".

    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.

  • < drive >: \ is not accessible. access is denied.

    Hello

    I created a VM installed vm tools. so I decided to add a disc more to the system (windows 7 x 64 bit).

    When I format the drive. disc is created and formatted normally but when I want to access it, watch somehow I have no right.

    user with which i m trying to access is domain administrator and UAC is disabled.

    I deleted this record and created another, same scenario. I can't access the created disc.

    any ideas?

    Since you in a field, there are group policies restrict your access?

    Perhaps you could use diskpart to verify if the drive is in read-only mode?

  • 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:
