Access to partition data denied

Hello,

I reinstalled Windows 10 on the system-dedicated partition of a drive, but since then I can no longer access the data partition; a message says access denied, and I can't find out what to do. Of course, I don't want to format it.

I tried the solution here "You need permission": what to do?

But that applies to folders; I thought it would be the same for partitions. However, when I manage to change the owner and want to save the permission changes, it says "unable to save permission changes on (E:)." Before this message, I get another one that says "failed to enumerate objects, access denied." Access denied again... even though the boxes for granting access still show as checked.

I am afraid to touch anything; the only box I haven't checked is "apply these permissions only to objects and/or containers that are part of this container" in the advanced security settings for E: "under permissions, permission entries (list of users, concerning me there are system and my administrator account) and modify, after selecting one of these two."

Finally, I wanted to remove the administrator to re-add it to the permission entries, and now I have a small red cross for my administrator account in properties, security, group or user name! I therefore need help.

Edit (upon rereading the tutorial, I realize that I haven't checked: Replace all child object permission entries with permissions that can be inherited from this object. But now I don't dare to.

      Thank you for this link.

      With using takeown which modifies the registry or powerRun I need an opinion, if possible:

      First, if I restore to a date prior to my manipulation, can that help? I would just need to check in the Advanced Security Settings window the box Replace all child object permission entries with inheritable permission entries from this object. I would then have "This operation will replace the explicitly defined permissions on all descendants of this object with inheritable permissions from Data E:" (I don't know what that means).

      If that doesn't work, I will try according to malekal.

      My second question is if I connect the hard drive externally before all this to another PC, could that be a source of additional conflicts later on?

      Hello,

      As takeown brought nothing, I managed to do it by reinstalling Windows again... just by designating you as the owner, using your username in the designated box and then checking the box to replace the owner of subcontainers and objects.

      ...I didn't have to check the box Replace all child object permission entries with entries inherited from this object.

      However, the first time I click on a folder it always tells me "you do not have the necessary permissions to access this folder" without refusing me access since by clicking continue, I can access it.

      For those looking for a solution without going through the reinstallation of Windows, don't waste time deleting accounts in permission entries, that caused me problems (and if it's too late, and you are looking for the answer only after fiddling, except for reinstalling Windows... good luck, not sure you will find a satisfactory answer.

      Note that in this reinstallation of W10 I do not have System in the list of users for my data partition, I don't know why or what it changes. I also didn't have any users before doing the ownership change operation while during my previous install I had System and my Administrator account without doing anything different...

      Also, note that I had given a name to this partition but that only a drive letter is assigned this time and acts as a name, go figure why...
