Solved How get back the ability to makes changes to a file

[Pooky1959]

I have been trying to do updates to programs I have on a external hard drive.
For the last few weeks I have been trying to update a few programs; but receive a message saying that I don't have authority to make changes. I can't even delete an empty folder.
I am logged on as administrator, and click to 'Allow' changes. I have tried going into the properties, the security of that folder and it says that Administrators have full control. Although the General tab says it is read only.
I have even downloaded the "Take Ownership" program; but when I right click the folder and chose that option, the Command Prompt opens and says that I am denied access to all that folders files.
Any ideas?

Check Disk

Have you tried checking the HDD for errors?

After I have used it at TAFE, one of my external HDDs often claims that it is "Read-only".
I have to run "Error-checking" before it will behave normally.

The result of the error checking is always, "No problems found".

Ok. So I did the check as suggest. I received no errors. And when I check the properties on my "Programs" folders it says that Administrators have full control. Yet I can still not even delete this empty folder. And when I click the security tab I get this message "The Permissions are incorrectly ordered, which may cause some entries to be ineffective", so I click "ok", and it opens and not one of the Groups or Users has any permission. I tried to "edit" but get a message that say it was incorrectly ordered, I click re-order and try to change the access and get another error message denying me access and even though I click Continue, I another error message saying that permissions were NOT changed "Access is Denied". The General tab for my 'Programs" folder is still Read-only, should I change this?

Everyone and/or Owner

Have you tried adding "Everyone" to the "Group or user names:"?

​

Also, check the "Owner" tab in "Advanced Security Settings" (click the "Advanced" button in step 1 above).

I was a pain. I changed the Security permissions and had to click 'Continue' about fifty times to allow that change to happen. But now I am able to delete folders and update programs.
Thank you!

No problem.

Be aware that "Everyone" will have the permissions you selected (i.e. it is not a very secure way to set the permissions).
It's a "quick and dirty" fix.

I suggest that you copy your data to another HDD (if possible) and then reformat the troublesome HDD.
Remember to check the files for malware.
