Administrator locked out of secondary hard drive -- Permissions, Security tab -- Windows 7 on Windows Domain

I managed to change permissions on my own hard drive and locked myself out completely (was my C drive but now set up as a slave). Now the security tab doesn't even show up. Not sure exactly what I set it to that caused the problem. I can only guess that it was a deny setting on Everyone or something???

I've tried takeown.exe from an elevated cmd prompt using the local admin as well as the domain admin among a number of other things that have not worked.

Any ideas?

Thanks.

From an elevated command prompt, takeown.exe will have to work, no room for arguing. Please quote the error again, so others can see it.

So it could be that the file system (the security descriptors in particular) are corrupt. Do a checkdisk on it to see if errors can be corrected. chkdsk /r d:

I've attached a screenshot of chkdsk's progress through the security descriptors stage... I'll update you once it's completely done.

this computer logs onto the domain ?

Trying logging on as a local user if administrator is not defined

from elevated command prompt

net user administrator /active:yes

go to control panel and set the password for this local account.

logoff domain logon to the computer name using administrator

I have not tried using a linux live boot disk and copying files from one drive to another from there... At this point really if I can just get to my desktop I'll be happy. Almost all of my data exists on a secondary drive which I do have access to.

Would linux ignore windows file permissions?

does windows use some sort of encryption or something to enforce these permissions? it seems like there would be something in linux that could let you ignore them, no?

Maybe GetDataBack  can help... GetDataBack Simple will recover your data if the hard drive's partition table, boot record, FAT/MFT or root directory are lost or damaged, ...GetDataBack Simple can even recover your data when the drive is no longer recognized by Windows.

I don't know if the free version is limited in functionality, though.

I actually own the full version of this program... I was leaning toward recovery software but wasn't sure if it would work. This is definitely my next step.

This wasn't a soluton to keeping the partition intact but at least I saved the files I needed.
