Answer found: "replacing invalid security id with default security id"
I am posting this here because this "replacing invalid security id with default security id" just happened to me.
(There was an old thread here that was 2863 days old, but I figured maybe to cut out the old for the new thread.)
The issue: Windows insist on checking your hard drive for errors and if you are like me, you turn on the power and walk away for a minute and it defaults into checking. When I came back, I saw that it was into 36,000 and counting "replacing invalid security id with default security id" actions. When Windows finishes this "replacement", you can't move, copy or access files. It takes forever to complete and then just to find the drive is fubared.
In my case, I have two partitions on a drive that it wanted to check, and while it was doing the first one, I hit the reset button. That partition became totally unaccessible. (It was a storage and odd work drive, not a boot drive.) I could not do anything to or for it. Properties said "Zero" space and files on the size. (I wasn't going to try "Format".) Windows would not let me go into safe mode either, but reading posts told me it would not work. Many places this issue was asked about and all were dead ends. I tried suggestions like programs called Unlocker... that couldn't.
And after searching for this across the net, one suggestion came up in a similar thread. The suggestion wasn't much associated to the issue but it was something to try after reading of all the failures to fix the issue.
The suggestion is: Hiren's Boot CD.
I happened to still have a copy laying around, and even though it boots into a Win XP mini op system, I gave it a try. It failed to boot once but I tried again. Once it booted, I could access that drive. I thus went onto copying everything from that drive to another to make sure I had a copy, as it was near 500 gigs of stuff.
Once I had finished copying, using Windows explorer, I right clicked the drive and found I had a couple of options to try. One was changing the permissions to "everybody" and the other was remove attributes. I did them both. I shut down, removed the drive I copied to and rebooted. Yeah, freakin' Windows wanted to scan those drives again, but I denied it to. But when Windows 7 booted, I had access to that drive/partition. I click on a folder and I would get "You don't have permission to access the folder, click continue to permanently change access", which gave my access.
So why did this happen?
I would guess that it is because I let Windows 10 scan the drive, and it decided to change a few attributes. Why do I think that is true? Because all these dead-end searches happened in the period of XP to 7 transition. So I think Windows 7 did the same to XP then, and Windows 10 is going to be doing it to Win 7. I assume it's Microsoft's dirty little trick to expel Win 7 attributes. (Just a guess.)
Anyhow, I wanted to post this positive result for others to see. Perhaps another person is going to experience this, go through hours of searching and reading, or happen upon this post and find the answer sooner.
And I just did a quick search and found that some folks made a newer version (Win 10) than the XP one I used. It and the old one I used can be found at
Hiren's BootCD PE
I hope this helps you all.
