Found this: answers.microsoft.com See second reply ! No clue whether it will work. But as your old system was Windows 7 there is a chance it could work !
I had already done that. All settings are set to allow full access by anyone on the network, no password protection, etc.
Also, I've gone to the Credential manager and it shows the network that pops up when I try to access the folders, but there is no "show" button to click to show me the password. I didn't need a password in Win 7, I just want to eliminate the need so I can assess my backup files.
There are other solutions, but all depends a bit on whether you have a local accont or a Microsoft account, I think.
You could try to log into save mode or try to log into the Microsoft "build in administrator account", which is a special administrator account, that has even higher priviledges than the normal administrator account. To enter this account, you need to type the following at cmd prompt (with admin rights !): "net user administrator /active:yes".
It will confirm whether the action was a succes. Then "log off". When logging in again, you will see two accounts: your usual user /administrator account and the newly created special administrator account. Log into the new account (may take some time, because windows will create the account) and try to open the inaccessible folders again from this account.
When successful, log out of the new account and go back into your user account. Don't forget to type "net user administrator /active:no". From your user account !!! This will remove the newly created account, which is necessary for security reasons.
There is also another solution to remove passwords for
a) the administrator and
b) the user
through the cmd prompt (3rd option !!! on the following page) : www.top-password.com In a local account, just type a star (*) behind the indicated cmd prompt for the user, respectively the administrator. Then you will be asked for a new user or administrator password. Hit enter (twice) instead of a password and all passwords should be gone.
I solved it! Despite the fact that this problem only cropped up after installing Windows 11, the actual source was connected to the Seagate drive itself. I finally figured that out and with some effort, have regained access to my drive and files. Thanks for your suggestions Roger. By trying, and eliminating Windows options, I turned inward and figured out it was a Seagate issue.
