C:\ is not accessible access is denied Location is not avail

by justinbowness15 / January 19, 2013 11:36 PM PST

Hello people,
I hope somebody can put me in the right direction here.

For some unknown reason i have come to my computer and whenever i click on the C: My computer or any icon on my desktop or try and edit any file (delete etc) i get the pop up message C:\ is not accessible access is denied Location is not available.

I thought this might have something to do with user accounts however I am the only user and administrator of the laptop and have all wrights, box's ticked.

Any help would be great.

Just a recap. Admin is not God.
by R. Proffitt Forum moderator / January 20, 2013 1:15 AM PST

As long as you think you have all rights, you may be stumped and won't look into the usual. Let's get past the "I'm the only user/admin" and remember that even the admin must obey NTFS permissions.

And you would try a new Admin account. And again the old lesson of the single account can not be forgotten. Keep an admin spare account.

Sorry that I can't guess which permission is off but we must get past the single user/admin hurdle before we can continue as well as getting our spare admin account in place.

Remember I only have the clues so far.

Some of the newer antivirus suites do block root directory modifications. There is rarely a reason to do this to C:\ so we'll have to boot safe mode or keep digging as to why this PC differs.\+is+not+accessible+access+is+denied+Location+is+not+available finds many prior discussions and I rarely duplicate these prior solutions.

Right or wrong, we get to use research on this. We've covered the basics here and good to read you now have a spare admin account.

-> Remember that many commands such as the CMD prompt will do this unless we "run as Admin". This is nothing new but I find folk that need to talk about Admin and God issues at times. In Linux for example, root is almost God like but you may still need to chmod this or that to dust off an item.

What do you think the next thing should be that i try??

Try the prior discussions.

The run as admin is the usual answer. I've had to do that with CMD and from there I can use notepad to edit boot.ini which is in the root folder.

I tried the "run as admin" for cmd but nothing opens (start menu just closes) i left click it or open and cmd opens as it should

There's a clue.

It's a slim one but my next move given only the clues so far is to try this in SAFE MODE. If that fails I'm off to run system scans if uninstalling the security suite doesn't bring it back to life.

This is the first solid clue that something is borked with this OS on this PC. Up till this point it sounded as if it's the old issue and discussion that we have to slog through.

Any more clues would be needed for me to not think this is some infection or antivirus protection.

Hi bob, man you know your stuff, hopefully you'll help cure me.

System scans?

Ive unistalled my security kit and still no look.

From all the error codes and fails it seems like a user account problem as it says restricted , denied, etc

Again. By default you can tinker with the root folder.

Oh sorry i must not have been clear. It does apply to all files and folders. I can use, or open most files but not move or delete them.

When i do a single left click on C:\ drive it just brings up the access denied message immediatly.

I see Kees noting Drive Permissions.
by R. Proffitt Forum moderator / January 21, 2013 12:12 AM PST
In reply to: bob

It's pretty rare but once in awhile you find folk tinkering with permissions and forget they did so. It took a lot of posts to see the full issue as I took your words as-is and know that the root folder is protected for very simple reasons.

Try the drive permissions next.
